spring cloud gateway modify response headersspring cloud gateway modify response headers
If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. The pattern is an Ant-style pattern with . If so, the same rules apply. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. The PreserveHostHeader GatewayFilter factory has no parameters. Modify request body. AddRequestHeader is aware of the URI variables used to match a path or host. Want to remove the "warning cannot modify header information" error from your WordPress website? There should be no reason why a filter cannot modify a response header. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) the request should only be allowed if it comes from a trusted list of IP addresses used by those In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. 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. 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. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. value or the String representation of the HttpStatus enumeration. You can read more about them in the. 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. .application.yml. Am I doing it wrong? The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. Embed. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is The Reactor Netty HttpClient and HttpServer can have wiretap enabled. In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. This predicate extracts the URI template variables (such as sub, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. The default filter is a rewrite path filter with the regex /serviceId/?(?. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). You can use it inside a regular Spring web handler as a method parameter. 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. You can enable, disable, or configure policies to control how they modify APIcast. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. Currently, only forward: schemed URIs are supported. The Passing headers with Spring Cloud Feign. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. 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 PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. 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). Getting the refreshTokenMono is webclient call which is in a different service.. By the time it gives the response, main response is already about to commit and wont allow us to modify the response headers. Most examples below use the shortcut way. method: Method name in the service that handles the request. Those values are then available for use by GatewayFilter factories. This uses Java regular expressions for a flexible way to rewrite the request path. We do this already Spring Cloud Gateway - read response body and set response headers Ask Question Asked 1 year, 11 months ago Modified 1 year, 11 months ago Viewed 675 times 0 I want to implement a GatewayFilter that reads the response body and out of this the response code is determined and should then be set afterwards. For relative redirects, you should use uri: no://op as the uri of your route definition. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. 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). SetResponseHeader is aware of URI variables used to match a path or host. status codes that if returned will cause the circuit breaker to be tripped. 1. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. 4.1. Zuul profile. The following listing shows how it works: This style also allows for more custom predicate assertions. This type of Repository is not suited to populate Routes across multiple Gateway instances. The preceding route matches if the request contained a red query parameter whose value matched the gree. pass the authentication token downstream to the services (in this case Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services regexp, so green and greet would match. 1050. Naming Custom Filters And References In Configuration, 18. - thaneesh shanand Apr 16, 2018 at 1:05 Refresh the page, check Medium 's site status, or find something interesting to read. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean In subsequent calls, this value is recalculated with the number of seconds left until the response expires. URI variables may be used in the value and are expanded at runtime. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. Route filters are scoped to a particular route. By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. Let's simplify this scenario. Multiple matching segments are allowed. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. The resulting response is similar to the following: The response contains the details of the GatewayFilter factories applied to any particular route. Typically, there will be a name key and an args key. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. 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. URI variables may be used in the value and will be expanded at runtime. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. 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. returned from the route it wraps. 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). You must use $\ to mean $ because of the YAML specification. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. When doing so, you need to make sure to include the default predicate and filter shown earlier, if you want to retain that functionality. This predicate matches with a header that has the given name whose value matches the regular expression. httpStatusCode: The HTTP Status of the request returned to the client. For the external controller/handler scenario, headers can be added with exception details. Closing due to lack of requested feedback. The route configuration allows applying CORS directly to a route as metadata with key cors. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. This filter works only with HTTP (including HTTPS) requests. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. To provide the same CORS configuration to requests that are not handled by some gateway route predicate, set the spring.cloud.gateway.globalcors.add-to-simple-url-handler-mapping property to true. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium The Between route predicate factory takes two parameters, datetime1 and datetime2 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, you can reference the bean by name using SpEL. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. return r.host("*.somehost.org").and().path("/somepath") The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. Options. The filter takes a maxSize parameter. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. The following examples show how to set up global pre- and post-filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. Value 3.9. In 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. To configure Global http timeouts: The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. It is defined by an ID, a destination URI, a collection of predicates, and a collection of filters. Sharing Routes between multiple Gateway instances, 17.1. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. If the new named header already exists, its values are augmented with the new values. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. This is the number of tokens the token bucket can hold. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. Easy to extend and/or customize using standard Spring patterns The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. There are many caching cases on the network, but there are various Bug problems in the testing process. This paper will introduce its usage in detail. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. Sign in To write a custom global filter, you must implement GlobalFilter interface as a bean. Server. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. The RemoveHopByHop Headers Filter removes headers from forwarded requests. API gateway provides a unified access for services in microservices architecture. reverse proxies. The status parameter should be a 300 series redirect HTTP code, such as 301. It is the name of the header to be removed. So, if the downstream server responded with X-Response-Red:1234, it will be replaced with X-Response-Red:Blue, which is what the gateway client would receive. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. A number of timeouts are associated with this handshake. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. The following describes an alternative style gateway. Spring Cloud Gateway. .route("test1", r -> { For example, to reference a filter named Something in configuration files, the filter Properties. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. Removes an existing route from the gateway. 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. If the information is not provided within the next 7 days this issue will be closed. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. }, 4. 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. 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). Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. Retries are performed after a backoff interval of firstBackoff * (factor ^ n), where n is the iteration. The gateway maintains a client pool that it uses to route to backends. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. Filter: These are instances of GatewayFilter that have been constructed with a specific factory. You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. Predicate: This is a Java 8 Function Predicate. Spring cloud gateway response body modification. The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. 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. The RemoteAddr Route Predicate Factory, 5.10.1. connect-timeout must be specified in milliseconds. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. URI variables may be used in the value and are expanded at runtime. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). Writing Custom GatewayFilter Factories, 17.2.1. Well occasionally send you account related emails. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. In future milestone releases, there will be some KeyResolver implementations. .metadata(RESPONSE_TIMEOUT_ATTR, 200) By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. By default, if the KeyResolver does not find a key, requests are denied. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. aws api gateway parameter mapping. That is not a complete working sample, it is just some code. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. connect-timeout must be specified in milliseconds. The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. 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 spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). Spring cloud gateway response body modification. 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 following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. to the exchange attributes. This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. The RemoveResponseHeader GatewayFilter factory takes a name parameter. If the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. The RequestHeaderSize GatewayFilter factory takes maxSize and errorHeaderName parameters. consumer can be a pure Client (like an SSO application) or a Resource 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. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. The following example configures an AddRequestParameter GatewayFilter: This will add red=blue to the downstream requests query string for all matching requests. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. Then the proxy request is made. Looking for a place to stay in Gunzenhausen? This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. 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.
