kandi X-RAY | spring-cloud-gateway Summary
This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. 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.

I'm trying to build a simple api-gateway using spring-cloud-gateway. So far I understood the basic principle but I'm running in a specific Problem:
The target url which I'm forwarding my request potentially contains zero, one or multiple path segments. Unfortunately, these path segments are ignored....

Ok, I found the answer: According to here it is intentional, that the path of the uri is ignored. So in my case, the set path filter would fix the problem:
I have a scenario that I have some microservices, cloud gateway and eureka server. All microservices and cloud gateway registered on the eureka server. Cloud gateway will securing all the downstream services. When any user want to access the service first it will fill out the username and password for authentication on the cloud gateway. If the user will be authentic then it will access the service by the gateway route that is already set in application.properties file but I want when the user will authentic and access the service then I can also get user authentic credential in downstream services or microservices that are behind the cloud gateway. In other word I want to getting principle values that is set on the gateway in downstream service. So, After searching many days I got a Global Filter Implementation link but this filter code in Kotlin and I am not familiar with Kotlin, So unable to understand of this. I want to implement this in Java. Basically this filter for adding username and user roles to headers of downstream services request. How can I convert this filter into java.
Here is the Workflow

I believe it's something like following
I have a React application based on Typescript which is hosted on my PC. I use Spring gateway to forward requests to another microservice. GET requests are working fine but for POST requests I get:

It seems that your issue is about local development only.
Create react app solves precisely this by supporting the dev server to serve as a proxy to your API endpoint.
Just add the API domain in the
proxy key in package.json. More on this here
For production you should either host them both under the same domain (using a reverse proxy to route static content vs api request based on the URL path), or find a permanent cors friendly solution on your backend.
Cors is a browser feature and cannot be disabled. Though, when not using the POST method you can get around the preflight but you still can't access the response body without the proper headers set

The problem was occurring because the default authentication manager wasn't working for me, I had to implement one specifically for my problem.

ANSWERAnswered 2022-Jan-09 at 02:12
OPTIONS pre-flight request is related to CORS policy and it is sent by the Browser automatically, so you can not disable it.
If you have access to the Server code, you can add
Access-Control-Allow-Origin: YOUR_DOMAIN header in the response message.
I've deployed an application in Kubernetes with two pods. If I directly invoke its Kubernetes service (
http://app:8080) it will balance the requests between those two pods using round robin.
The actual runtime contains a Spring Cloud Gateway pod in front of the application, configured this way:...

In order to make Spring Cloud Gateway distribute the load and not stick to one pod I had to:

You don't have any
predicate specified for your
route definitions - which means both of them match any incoming request. From Spring Cloud Gateway:
Clients make requests to Spring Cloud Gateway. If the Gateway Handler Mapping determines that a request matches a Route, it is sent to the Gateway Web Handler.
Route: Route the basic building block of the gateway. It is defined by an ID, a destination URI, a collection of predicates and a collection of filters. A route is matched if aggregate predicate is true.
Since you don't have any
predicate specified - your route matches the incoming request and the last one is winning.
I'm trying to build a gateway with load balancer by using spring-cloud-gateway But when I hit gateway, it gives me 404 instead of routing me to the registered service in eureka
I don't want to use auto-discover feature, so I use manual routing instead.
my code is uploaded here : https://github.com/gry77/poc-spring-cloud-gateway
How can I fix it ?...

GatewayFilter, you should register the filter like this:
I am trying to forward client certificate information from Spring Cloud Gateway to microservices behind it. I modified the Netty config and it is successfully requesting a client cert from the client, but I don't see it forwarding it to the microservice behind it. In Apache we used to use +ExportCertData which populated a handful of headers with the client certificate DN, validity time, etc. Does Spring Cloud Gateway have any out of the box functionality like this?
I found these 2 questions which seem similar, but neither had very explicit answers. spring cloud gateway forward client certificate and Does anyone have a simple example of implementing x509 mutual authentication in Spring Cloud Gateway/Spring WebFlux?...
ANSWERAnswered 2021-Aug-24 at 12:39
After playing with it for a while, changing something on the Netty HttpClient did not seem to be right because as far as I could tell it did not know anything about where the request came from. However I found that the filter chain had all the information I needed, so I put in a custom GlobalFilter which adds the certificate information to the header like what Apache does.
