CacheRequestBody then places it in the attributes available from ServerWebExchange.getAttributes(), with a key defined in ServerWebExchangeUtils.CACHED_REQUEST_BODY_ATTR. AddRequestHeader is aware of the URI variables used to match a path or host. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. 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). The status parameter should be a 300 series redirect HTTP code, such as 301. The following describes an alternative style gateway. This predicate matches requests that happen after the specified datetime. 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 following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. Route: The basic building block of the gateway. 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). Modifying the request body is a common requirement. 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. By clicking Sign up for GitHub, you agree to our terms of service and 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). There are convenience methods that you can use to mark an exchange as routed 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. URI variables may be used in the value and are expanded at runtime. You can read more about them in the. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. With MVC, it also supports forwarding to a local handler through the forward() method. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). This paper will introduce its usage in detail. After the proxy request is made, the post filter logic is run. .filters(f -> f.addRequestHeader("header1", "header-value-1")) The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. If You Appreciate This, You Can Consider: We are thankful for your never ending support. GitHub Gist: instantly share code, notes, and snippets. All pre filter logic is executed. Spring Cloud Gateway includes many built-in GatewayFilter Factories. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. This property takes a list of filters. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? 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. If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. Star 14. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. You can extend an abstract class called AbstractGatewayFilterFactory. ServerHttpResponse interface. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. status codes that if returned will cause the circuit breaker to be tripped. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. The PreserveHostHeader GatewayFilter factory has no parameters. Passing headers with Spring Cloud Feign. Naming Custom Filters And References In Configuration, 18. If the information is not provided within the next 7 days this issue will be closed. name can contain a space-separated list of header names. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. You must use $\ to mean $ because of the YAML specification. The filter takes a host parameter. 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 the Gateway Handler Mapping determines that a request matches a route, it is sent to the Gateway Web Handler. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. This handler runs the request through a filter chain that is specific to the request. To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. 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 filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. cloudflare tunnel home assistant 19 3407 . 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. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. The collection of filters applied to the route. 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). connect-timeout must be specified in milliseconds. It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. Retrieving Information about a Particular Route, 15.6. The following listing shows the KeyResolver interface: The KeyResolver interface lets pluggable strategies derive the key for limiting requests. The input type is a Spring Framework ServerWebExchange. forwards the incoming token to outgoing resource requests. NOTE: This is not recommended for production. This vulnerability is known as HTTP Response Splitting. Retrieving the Routes Defined in the Gateway, 15.5. If so, the same rules apply. 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. To retrieve the routes defined in the gateway, make a GET request to /actuator/gateway/routes. To configure per-route timeouts: To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. .build(); In order to write a Route Predicate you will need to implement RoutePredicateFactory as a bean. It must be a valid Spring HttpStatus. The filter also looks in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR attribute to see if it equals lb. It adds more detail to each route, letting you view the predicates and filters associated with each route along with any configuration that is available. By default, if the KeyResolver does not find a key, requests are denied. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. 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. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. This is useful when you try to support CORS preflight requests and your route predicate does not evaluate to true because the HTTP method is options. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. Am I doing it wrong? @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 two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. status: The HTTP status of the request returned to the client. The following listing shows how it works: This style also allows for more custom predicate assertions. The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. The RemoveResponseHeader GatewayFilter factory takes a name parameter. It is the name of the query parameter to be removed. The following example creates a Logback configuration: You can configure the gateway to control CORS behavior globally or per route. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. Note that the $ should be replaced with $\ because of the YAML specification. 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 following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. 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. 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. ALWAYS_STRIP: The version is always stripped, even if the original request path contains version. 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; . I got the root cause. 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. Then the proxy request is made. This predicate matches cookies that have the given name and whose values match the regular expression. To configure Global http timeouts: 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. 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. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. You can use it inside a regular Spring web handler as a method parameter. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. URI variables may be used in the value and are expanded at runtime. Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. SetResponseHeader is aware of URI variables used to match a path or host. responseCode; responseHeaderTransformations; responseMessage; type; . reverse proxies. 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. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. 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. It must be a Java System Property, not a Spring Boot property. 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]. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled 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. Since the request can be read only once, we need to cache the request body. application.yml. 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). Displays the list of routes defined in the gateway. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. 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 . The following example configures /actuator/gateway/routes: This feature is enabled by default. This filter (which configures the local response cache per route) is available only if the local response global cache is enabled. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. In future milestone releases, there will be some KeyResolver implementations. Configuring Predicates and Filters For, 15.4. 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). 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 ? You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. It uses the Host header, scheme, port and path of the current request to create the various headers. If it is not matched, the filter does nothing. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. Route filters are scoped to a particular route. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. It offers a simple way to manipulate the request path by allowing templated segments of the path. Spring Cloud CircuitBreaker supports multiple libraries that can be used with Spring Cloud Gateway. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. - thaneesh shanand Apr 16, 2018 at 1:05 The first one is the The following listing shows how to modify a response body GatewayFilter: The PrefixPath GatewayFilter factory takes a single prefix parameter. That is not a complete working sample, it is just some code. For a full working sample see this project. a circuit breaker. Sumant Rana 77 Followers Embark on a cloud native journey Follow More from Medium 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. Download ZIP. The algorithm used is the Token Bucket Algorithm. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. To write a custom global filter, you must implement GlobalFilter interface as a bean. the request should only be allowed if it comes from a trusted list of IP addresses used by those 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). privacy statement. regexp, so green and greet would match. The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. series: The series of status codes to be retried, represented by using org.springframework.http.HttpStatus.Series. The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. If the fallback is called, the request is forwarded to the controller matched by the URI. The pattern is an Ant-style pattern with . value or the String representation of the HttpStatus enumeration. 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). The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. Then look no further than Parkhotel Altmuehltal, a family-friendly hotel that brings the best of Gunzenhausen to your doorstep. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. This predicate matches requests that happen before the specified datetime. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. Easy to extend and/or customize using standard Spring patterns which are java ZonedDateTime objects. The protocolsRegex parameter must be a valid regex String, against which the protocol name is matched. Setting this value to zero blocks all requests. It adds the Host header, scheme and port of the current request to any existing Forwarded header. This interface and its usage are subject to change in future milestone releases. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. The arguments are typically listed in the order that are needed for the shortcut configuration. This can be used with reverse proxies such as load balancers or web application firewalls where returned from the route it wraps. To clear the routes cache, make a POST request to /actuator/gateway/refresh. 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. keyResolver is a bean that implements the KeyResolver interface. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. This is the number of tokens the token bucket can hold. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. 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. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. Those values are then available for use by GatewayFilter factories. . 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). 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 an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. 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). consumer can be a pure Client (like an SSO application) or a Resource Most examples below use the shortcut way. There should be no reason why a filter cannot modify a response header. How does it work? The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. : spring-boot-starter-oauth2-client 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa existing host header, scheme and port the...
