spring cloud gateway modify response headers

InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. connect-timeout must be specified in milliseconds. All pre filter logic is executed. AddRequestHeader is aware of the URI variables used to match a path or host. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled . The XForwarded Remote Addr Route Predicate Factory, 6.5.1. 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. . It should be available as a GitHub (or similar) project or attached to this issue as a zip file. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. 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 following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. to your account, I am trying to modify a header of response in a post filter of gateway,the filter handle a cors problem which would filt websockt service ,the websockt service is a micro-service which must been decorated with cors configurationso a websockt request will get a response with multiple header like Access-Control-Allow-Origin, to solve this questioni must modify the response header of the key Access-Control-Allow-OriginHowever ,when i do this, a error occured, java.lang.UnsupportedOperationException: null at org.springframework.http.ReadOnlyHttpHeaders.set(ReadOnlyHttpHeaders.java:99) ~[spring-web-5.1.6.RELEASE.jar:5.1.6.RELEASE] at com.apigw.filter.CORSFilter.lambda$filter$0(CORSFilter.java:84) ~[classes/:na] at reactor.core.publisher.MonoRunnable.call(MonoRunnable.java:73) ~[reactor-core-3.2.8.RELEASE.jar:3.2.8.RELEASE]. - thaneesh shanand Apr 16, 2018 at 1:05 1. 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). import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. Modifying the request body is a common requirement. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. The following describes an alternative style gateway. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. 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). This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. If youre using load-balanced routes, you need to explicitly define your. These are special filters that are conditionally applied to all routes. Retrieving Information about a Particular Route, 15.6. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. 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 Since the request can be read only once, we need to cache the request body. The preceding route matches if the request contained a red query parameter whose value matched the gree. The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. 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 filter takes a maxSize parameter. 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. .build(); The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. The collection of filters applied to the route. The following listing shows how to add local response cache GatewayFilter: The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. 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. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. In this case, the rate limiter needs to be allowed some time between bursts (according to replenishRate), as two consecutive bursts results in dropped requests (HTTP 429 - Too Many Requests). Spring cloud gateway response body modification. Writing Custom GatewayFilter Factories, 17.2.1. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. If you would like us to look at this issue, please provide the requested information. Already on GitHub? If so, the same rules apply. 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). 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. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). Sharing Routes between multiple Gateway instances, 17.1. This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). The args key is a map of key value pairs to configure the predicate or filter. Am I doing it wrong? This predicate matches requests that happen after datetime1 and before datetime2. This property takes a list of filters. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. Easy to extend and/or customize using standard Spring patterns It uses the Spring WebSocket infrastructure to forward the websocket request downstream. 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). From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. The predicates defined by RouteDefinitionLocator beans are combined using logical and. By clicking Sign up for GitHub, you agree to our terms of service and Filter: These are instances of GatewayFilter that have been constructed with a specific factory. This is the rate at which the token bucket is filled. 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). consumer can be a pure Client (like an SSO application) or a Resource By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. However, you can also reroute the request to a controller or handler in an external application, as follows: In this example, there is no fallback endpoint or handler in the gateway application. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). URI variables may be used in the value and will be expanded at runtime. This is the value of the Location header. 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. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. Spring cloud gateway response body modification. value or the String representation of the HttpStatus enumeration. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. The Between route predicate factory takes two parameters, datetime1 and datetime2 It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. The following example below is invalid: The Redis implementation is based on work done at Stripe. GitHub spring-cloud / spring-cloud-gateway Public Notifications Fork 2.9k Star 3.9k Code Issues 337 Pull requests 39 Actions Projects Security Insights New issue How to modify spring cloud gateway response headers #1092 Closed It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. 25Modify Response Body GatewayFilter Factory; 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. 3,AddResponseHeader GatewayFilter Factory. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. status codes that if returned will cause the circuit breaker to be tripped. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. All of these predicates match on different attributes of the HTTP request. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. To write a custom global filter, you must implement GlobalFilter interface as a bean. 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 following example configures a between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). However, there is one in another application, registered under localhost:9994. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). The headers with the exception type, message and (if available) root cause exception type and message are added to that request by the FallbackHeaders filter. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. Note that the $ should be replaced with $\ because of the YAML specification. it is proxying. The SetRequestHeader GatewayFilter factory takes name and value parameters. It uses the Netty HttpClient to make the downstream proxy request. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). The gateway can listen for requests on HTTPS by following the usual Spring server configuration. A per-route response-timeout with a negative value will disable the global response-timeout value. status: The HTTP status of the request returned to the client. Have a question about this project? 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. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). Modify request body. In Currently, only forward: schemed URIs are supported. Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. Created 6 years ago. This predicate matches cookies that have the given name and whose values match the regular expression. outcome: The outcome, as classified by HttpStatus.Series. To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. The RemoveResponseHeader GatewayFilter factory takes a name parameter. Policy to specify how to modify the response code, body and headers. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. The path part of the request URL is overridden with the path in the forward URL. regexp, so green and greet would match. The status parameter should be a 300 series redirect HTTP code, such as 301. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. The Host route predicate factory takes one parameter: a list of host name patterns. The XForwarded Remote Addr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). the request should only be allowed if it comes from a trusted list of IP addresses used by those backoff: The configured exponential backoff for the retries. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. By default, it creates a NettyChannel by using the default TrustManagerFactory. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. If it is not provided, the value of the Host request header is used. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. You signed in with another tab or window. This type of Repository is not suited to populate Routes across multiple Gateway instances. It adds the Host header, scheme and port of the current request to any existing Forwarded header. 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)'. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. keyResolver is a bean that implements the KeyResolver interface. If it is not matched, the filter does nothing. Refresh the page, check Medium 's site status, or find something interesting to read. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. For the external controller/handler scenario, headers can be added with exception details. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. the ID of the service from the DiscoveryClient. It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. This filter also automatically calculates the. The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. The DedupeResponseHeader filter also accepts an optional strategy parameter. I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. If the fallback is called, the request is forwarded to the controller matched by the URI. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed in a single second (without any dropped requests). The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR.
