Jersey - Redirect after POST to outside URL
提问by Vuk Stankovi?
I'm using Jersey to create REST API. I have one POST method and as a response from that method, user should be redirected to custom URL like http://example.comthat doesn't have to be related to API.
我正在使用 Jersey 创建 REST API。我有一个 POST 方法，作为该方法的响应，用户应该被重定向到自定义 URL，这样http://example.com就不必与 API 相关。
I was looking at other similar questions on this topic here, but didn't find anything that I could use.

I'd suggest altering the signature of the JAX-RS-annotated method to return a javax.ws.rs.core.Responseobject. Depending on whether you intend the redirection to be permanent or temporary (i.e. whether the client should update its internal references to reflect the new address or not), the method should build and return a Responsecorresponding to an HTTP-301 (permanent redirect)or HTTP-302 (temporary redirect)status code.
我建议更改 JAX-RS 注释方法的签名以返回一个javax.ws.rs.core.Response对象。根据您希望重定向是永久的还是临时的（即客户端是否应更新其内部引用以反映新地址），该方法应构建并返回Response对应于HTTP-301（永久重定向）或HTTP -302（临时重定向）状态代码。
Here's a description in the Jersey documentation regarding how to return custom HTTP responses: https://jersey.java.net/documentation/latest/representations.html#d0e5151. I haven't tested the following snippet, but I'd imagine that the code would look something like this, for HTTP-301:
以下是 Jersey 文档中关于如何返回自定义 HTTP 响应的描述：https: //jersey.java.net/documentation/latest/representations.html#d0e5151。我还没有测试过以下代码段，但我想对于 HTTP-301，代码看起来像这样：
@POST
public Response yourAPIMethod() {
URI targetURIForRedirection = ...;
return Response.seeOther(targetURIForRedirection).build();
}
...or this, for HTTP-302:
...或者这个，对于 HTTP-302：
@POST
public Response yourAPIMethod() {
URI targetURIForRedirection = ...;
return Response.temporaryRedirect(targetURIForRedirection).build();
}
