Apache camel 将一个 URI 路由到另一个 URI

问题描述

是否可以将所有请求直接路由到另一台服务器?例如，将所有此项目特定的休息端点 localhost:8080/get-something 路由到另一个项目端点，如下所示: someIp:8081/get-something2 .像这样:

Is it possible to route all of request to another server directly? For example route all of this project specific rest endpoint localhost:8080/get-something to another project endpoint like this: someIp:8081/get-something2 . something like this:

from("localhost:8080/get-something")
.to("someIp:8081/get-something2")

或者这个:

rest()
            .path("/get-something")
            .get()
                .route()
.to("someIp:8081/get-something2")

我尝试了太多方法，但我做不到！

I've tried too many ways but I cant!

推荐答案

您可以使用基于 http 的组件(jetty 或 undertow)作为消费者(来自)并带有 matchOnUriPrefix=true 选项，然后发送它使用 bridgeEndpoint=true 选项到 http 组件.

You could use a http based component (jetty or undertow) as consumer (from) with matchOnUriPrefix=true option and then send it to an http component using bridgeEndpoint=true option.

示例:

from("undertow:http://localhost:8080/?matchOnUriPrefix=true")
.to("http4://google.com/?bridgeEndpoint=true");

这样任何发送到 localhost:8080/的请求都会被转发到 google.com/

That way any request sent to localhost:8080/ will be forwarded to google.com/

在浏览器中尝试 http://localhost:8080/，您将获得 google 网页.

Try http://localhost:8080/ in your browser and you will get google web page.

在浏览器中尝试 http://localhost:8080/search?q=camel ，您将收到camel"的响应；搜索.

Try http://localhost:8080/search?q=camel in your browser and you will get response for "camel" search.

在你的情况下，你可以这样做:

In your case you could do:

from("undertow:http://localhost:8080/?matchOnUriPrefix=true")
.to("http4://localhost:8081/?bridgeEndpoint=true");
