spring cloud gateway modify response headers

As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. You must use $\ to mean $ because of the YAML specification. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. Sign in The following example below is invalid: The Redis implementation is based on work done at Stripe. It is the name of the header to be removed. This interface and its usage are subject to change in future milestone releases. All of these predicates match on different attributes of the HTTP request. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. AddRequestParameter is aware of the URI variables used to match a path or host. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. Route: The basic building block of the gateway. Well occasionally send you account related emails. It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. The AddRequestHeader GatewayFilter factory takes a name and value parameter. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. 3,AddResponseHeader GatewayFilter Factory. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. Most examples below use the shortcut way. Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. Spring Cloud Gateway || Modify Response Body Using Post Global Filter modify response body of route in spring cloud gateway Hi everyone, have you ever worked with Filters ? In configuration, reference the bean by name using SpEL. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query the request should only be allowed if it comes from a trusted list of IP addresses used by those Here, you can modify requests and responses before or after sending the downstream request. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. It adds the Host header, scheme and port of the current request to any existing Forwarded header. The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. The most noteworthy thing here is: ServerHttpRequest or HttpMessage interface provides a method to get the request headers HttpHeaders getHeaders(); returns a read-only instance, specifically of type ReadOnlyHttpHeaders, mentioned here more than once I wrote this blog post using Spring Cloud Gateway version Greenwich.SR1. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). Otherwise, the original value in the client request is sent. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. . You can also define a rate limiter as a bean that implements the RateLimiter interface. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. There should be no reason why a filter cannot modify a response header. These are special filters that are conditionally applied to all routes. Modifying the request body is a common requirement. Setting this value to zero blocks all requests. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. The lowercase full name of the secure header needs to be used to disable it.. A route is matched if the aggregate predicate is true. Options. Spring Cloud Gateway. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . Displays the list of routes defined in the gateway. The following example configures a header route predicate: This route matches if the request has a header named X-Request-Id whose value matches the \d+ regular expression (that is, it has a value of one or more digits). statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. The request returns a 200 without a response body. This uses the URI templates from Spring Framework. The LocalResponseCache runs if its associated property is enabled (spring.cloud.gateway.filter.local-response-cache.enabled) and activates a local cache using Caffeine for all responses that meet the following criteria: The response has one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). URI variables may be used in the value and are expanded at runtime. If it is not, a status of HTTP 429 - Too Many Requests (by default) is returned. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. responseCode; responseHeaderTransformations; responseMessage; type; . The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. If you would like us to look at this issue, please provide the requested information. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. I think i have to go for a blocking call here. You can combine multiple route predicate factories with logical and statements. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. To configure Global http timeouts: To enable wiretap, set spring.cloud.gateway.httpserver.wiretap=true or spring.cloud.gateway.httpclient.wiretap=true for the HttpServer and HttpClient, respectively. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. Spring cloud gateway response body modification. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. Modifying the Way Remote Addresses Are Resolved, 5.12. Spring Cloud Gateway includes many built-in GatewayFilter Factories. URI variables may be used in the value and are expanded at runtime. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. Those values are then available for use by GatewayFilter factories. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. The HTTP Cache-Control header allows caching (that means it does not have any of the following values: no-store present in the request and no-store or private present in the response). The ServerHttpResponse instance is used to . For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services The route configuration allows applying CORS directly to a route as metadata with key cors. The The XForwarded Remote Addr Route Predicate Factory, 6.5.1. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). Route filters are scoped to a particular route. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. In order to modify APIcast behavior with custom policies, you must do the following: Add custom policies to APIcast Define a policy chain that configures APIcast policies Add the policy chain to APIcast 4.1. It is possible to create a gateway filter named without the. spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. Retrieving the Routes Defined in the Gateway, 15.5. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. return r.host("*.somehost.org").and().path("/somepath") In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. reverse proxies. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. To write a custom global filter, you must implement GlobalFilter interface as a bean. This is of particular use when using something like Spring Session with a lazy data store, and you need to ensure the session state has been saved before making the forwarded call. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. You can use it inside a regular Spring web handler as a method parameter. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. Value 3.9. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. It must be a valid Spring HttpStatus. The SetRequestHeader GatewayFilter factory takes name and value parameters. If the fallback is called, the request is forwarded to the controller matched by the URI. Filter: These are instances of GatewayFilter that have been constructed with a specific factory. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter: This listing adds 2 headers X-Request-Color-1:blue and X-Request-Color-2:green to the downstream requests headers for all matching requests. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. The RequestRateLimiter is not configurable with the "shortcut" notation. Already on GitHub? You signed in with another tab or window. Spring Cloud Gateway comes with one non-default remote address resolver that is based off of the X-Forwarded-For header, XForwardedRemoteAddressResolver. which are java ZonedDateTime objects. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. Predicate: This is a Java 8 Function Predicate. Add a response header named X-Request-Foo with a value of Bar to the original response. The filter takes a maxSize parameter. The Between route predicate factory takes two parameters, datetime1 and datetime2 #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. The collection of filters applied to the route. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. To disable it, set the following property: This will default to true in a future release. Once a request has been marked as routed, other routing filters will not route the request again, AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. .filters(f -> f.addRequestHeader("header1", "header-value-1")) Creating and Deleting a Particular Route, 15.8. The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). This is the rate at which the token bucket is filled. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). If the URL has a lb scheme (such as lb://myservice), it uses the Spring Cloud ReactorLoadBalancer to resolve the name (myservice in this example) to an actual host and port and replaces the URI in the same attribute. In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. This vulnerability is known as HTTP Response Splitting. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). }, 4. This could be useful for maintenance windows. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java. You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. Removes an existing route from the gateway. .metadata(RESPONSE_TIMEOUT_ATTR, 200) To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The filter takes a host parameter. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] APIcast standard policies The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). I got the root cause. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. The filter takes the following arguments: This file can be generated using protoc and specifying the --descriptor_set_out flag: service: Fully qualified name of the service that handles the request. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. .uri("http://someuri") The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. privacy statement. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. This handler runs the request through a filter chain that is specific to the request. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. This predicates matches the Host header that matches the pattern. A Token Relay is where an OAuth2 consumer acts as a Client and In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. The This uses Java regular expressions for a flexible way to rewrite the request path. 2016-10-05: 4.3: CVE-2016-6426 CISCO Embed. This section covers common problems that may arise when you use Spring Cloud Gateway. By clicking Sign up for GitHub, you agree to our terms of service and or check if an exchange has already been routed. The body is cached in a request attribute defined by. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. forwards the incoming token to outgoing resource requests. If so, the same rules apply. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). exceptions: A list of thrown exceptions that should be retried. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. This type of Repository is not suited to populate Routes across multiple Gateway instances. A per-route response-timeout with a negative value will disable the global response-timeout value. I suppose your issue may have been different than mine, but when I turned on trace logging I saw that my filter was executing after the response was sent and so I gave the filter a different order value that put it in the right order. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). the ID of the service from the DiscoveryClient. In configuration, you can reference the bean by name using SpEL. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. URI variables may be used in the value and will be expanded at runtime. The algorithm used is the Token Bucket Algorithm. There are many caching cases on the network, but there are various Bug problems in the testing process. The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true). ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. For example, to reference a filter named Something in configuration files, the filter The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. Let's simplify this scenario. None of the prior documentation applies to what follows. Response data is not cached if Cache-Control header does not allow it (no-store present in the request or no-store or private present in the response). /resource). You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. Modify request body. and puts it in a request header for the downstream requests. .route("test1", r -> { It accepts the first parameter to override the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours) and a second parameter to set the maximum size of the cache to evict entries for this route (KB, MB, or GB). The following example configures a SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. How does it work? When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. The following listing configures a RemoveResponseHeader GatewayFilter: This will remove the X-Response-Foo header from the response before it is returned to the gateway client. This applies the filter to all requests. With MVC, it also supports forwarding to a local handler through the forward() method. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. application.yml. The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. AddRequestHeader is aware of the URI variables used to match a path or host. Spring Cloud Gateway Response Modification Raw README.md Overview As of this writing, there's a somewhat limited/restrictive means of applying HTTP response transformations/modifications via Spring Cloud Gateway, probably because it needs to accommodate both the Mono and Flux (aka "reactive") models. The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. status: The HTTP status of the request returned to the client. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. This lets you match on anything from the HTTP request, such as headers or parameters.
