The following listing configures a SetStatus GatewayFilter: In either case, the HTTP status of the response is set to 401. This predicate matches requests that happen after datetime1 and before datetime2. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted While a Gateway is running you can use kubectl scale to modify the number of replicas. It uses the Netty HttpClient to make the downstream proxy request. This filter can be configured only by using the Java DSL. It adds the Host header, scheme and port of the current request to any existing Forwarded header. In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. It is the name of the query parameter to be removed. 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. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. the request should only be allowed if it comes from a trusted list of IP addresses used by those The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. You signed in with another tab or window. /resource). The RemoveRequestParameter GatewayFilter factory takes a name parameter. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. 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, @ryanjbaxter it seems a route filter,can i modify a response header in a global post filter,thanks. 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). import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; If you include the starter, but you do not want the gateway to be enabled, set spring.cloud.gateway.enabled=false. response-timeout must be specified as a java.time.Duration. let's see. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. Displays the list of GatewayFilter factories applied to a particular route. This route predicate allows requests to be filtered based on the X-Forwarded-For HTTP header. Spring cloud gateway response body modification. Zuul profile. URI variables may be used in the value and are expanded at runtime. outcome: The outcome, as classified by HttpStatus.Series. This allows more complex routing options, like forwarding sections of the original host or url path using PathPattern expression. The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. If two hops of trusted infrastructure are required before Spring Cloud Gateway is accessible, then a value of 2 should be used. }) You can customize the way that the remote address is resolved by setting a custom RemoteAddressResolver. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. 3,AddResponseHeader GatewayFilter Factory. The default filter is a rewrite path filter with the regex /serviceId/?(?. 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. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. This applies the filter to all requests. The SetRequestHeader GatewayFilter factory takes name and value parameters. Service 4.3. 4.1. To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) Spring Cloud Gateway. Displays information about a particular route. 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 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. You can read more about them in the. exceptions: A list of thrown exceptions that should be retried. The arguments are typically listed in the order that are needed for the shortcut configuration. Looking for a place to stay in Gunzenhausen? Refresh the page, check Medium 's site status, or find something interesting to read. Sign in Route: The basic building block of the gateway. It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. a circuit breaker. 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. This is the number of tokens the token bucket can hold. To clear the routes cache, make a POST request to /actuator/gateway/refresh. 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. Writing Custom Route Predicate Factories, 17.2. A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. Typically, there will be a name key and an args key. .metadata(RESPONSE_TIMEOUT_ATTR, 200) The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. .filters(f -> f.addRequestHeader("header1", "header-value-1")) .build(); Add a response header named X-Request-Foo with a value of Bar to the original response. Once matched, the Gateway executes pre-request logic on each of the filters applied to the route. 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 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 pattern is an Ant-style pattern with . AddRequestHeader is aware of the URI variables used to match a path or host. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. Raw. 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 RemoveRequestHeader GatewayFilter factory takes a name parameter. 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). For a full working sample see this project. The args key is a map of key value pairs to configure the predicate or filter. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. By default, if the KeyResolver does not find a key, requests are denied. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. However, there is one in another application, registered under localhost:9994. The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. It uses Java regular expressions for a flexible way to rewrite the response header value. also note that the gist doesn't take the decoders into account from upstream like here. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. Passing headers with Spring Cloud Feign. 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 This can be used with reverse proxies such as load balancers or web application firewalls where 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; . 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. The AddRequestHeader GatewayFilter factory takes a name and value parameter. In The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. The circuit breaker config object takes a list of SetResponseHeader is aware of URI variables used to match a path or host. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. You can extend an abstract class called AbstractGatewayFilterFactory. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. regexp, so green and greet would match. extracts an access token from the currently authenticated user, You can combine multiple route predicate factories with logical and statements. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). Fork 3. The ServerHttpResponse instance is used to . The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. You can add headers to the downstream response by using the header() methods on ProxyExchange. if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. Created 6 years ago. The following listing configures a RequestHeaderSize GatewayFilter: This will send a status 431 if size of any request header is greater than 1000 Bytes. Writing Custom GatewayFilter Factories, 17.2.1. It is the name of the header to be removed. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. 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. Once a request has been marked as routed, other routing filters will not route the request again, Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. The KeyResolver is a simple one that gets the user request parameter So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. You can also define a rate limiter as a bean that implements the RateLimiter interface. 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 uses the Netty HttpClient to make the downstream proxy request. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. Modifying the Way Remote Addresses Are Resolved, 5.12. For the external controller/handler scenario, headers can be added with exception details. status: The HTTP status of the request returned to the client. Currently, only forward: schemed URIs are supported. This uses the URI templates from Spring Framework. That is not a complete working sample, it is just some code. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. Predicate: This is a Java 8 Function Predicate. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean 2016-10-05: 4.3: CVE-2016-6426 CISCO This handler runs the request through a filter chain that is specific to the request. 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. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. To write a custom global filter, you must implement GlobalFilter interface as a bean. 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'. it is proxying. This filter works only with HTTP (including HTTPS) requests. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/1/ or /red/blue or /blue/green. The following example configures a PreserveHostHeader GatewayFilter: The RedirectTo GatewayFilter factory takes two parameters, status and url. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. This predicate matches cookies that have the given name and whose values match the regular expression. For example, you can match on the path segment of the URL or the HTTP method of the request. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. If basedOnPreviousValue is true, the backoff is calculated by using prevBackoff * factor. 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). For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). Each item defines the name and the arguments of a given predicate. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. 25Modify Response Body GatewayFilter Factory; 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). Cleanliness 4.4. 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. httpStatusCode: The HTTP Status of the request returned to the client. 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 ? SetRequestHeader is aware of URI variables used to match a path or host. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. aws api gateway parameter mapping. The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. The default list of headers that is removed comes from the IETF. Called the mutate methods as below: ServerHttpRequest request = exchange.getRequest () .mutate () .header ("headerkey", jwt) .build (); exchange.mutate ().request (request).build (); return chain.filter (exchange); However, the header is not injected to the backend api. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 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. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. The 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 /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. 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. @ryanjbaxter thanks, the core code is a filter https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt ,but it can't modify header in a post filter,is it a right way writing like this? The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. URI variables may be used in the value and are expanded at runtime. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is response-timeout must be specified in milliseconds. The following example configures a MapRequestHeader: This adds the X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. Spring Cloud Zuul is one of the core components of Spring Cloud Netflix subproject. Note that the $ should be replaced with $\ because of the YAML specification. There should be no reason why a filter cannot modify a response header. name can contain a space-separated list of header names. URI variables may be used in the value and will be expanded at runtime. if. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. This predicate matches requests that happen after the specified datetime. 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. 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 SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. 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. status codes you want to trip the circuit breaker you can either use an integer with the status code The first one is the The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. If youre using load-balanced routes, you need to explicitly define your. Naming Custom Filters And References In Configuration, 18. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. The RemoteAddr 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). If the input header does not exist, the filter has no impact. A per-route response-timeout with a negative value will disable the global response-timeout value. It does not work in a traditional Servlet Container or when built as a WAR. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. This predicates matches the Host header that matches the pattern. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). The RemoveResponseHeader GatewayFilter factory takes a name parameter. There are convenience methods that you can use to mark an exchange as routed To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. responseCode; responseHeaderTransformations; responseMessage; type; . Remote address is resolved by setting a custom global filter, you add. Or when built as a bean to /actuator/gateway/refresh rewrite path filter with the regex /serviceId/? ( <.
