自定义响应头泽西/ Java

问题描述

我正在努力实现以下目标。

I am trying to achieve the following.

从请求中读取自定义标头及其值：

Read a custom header and its value from Request:

name: username

现在，作出回应，我想在HTTP响应中返回相同的头 name：value 对。

Now, on response, I would like to return the same header name:value pair in HTTP response.

我正在使用Jersey 2.0实现的JAX- RS webservice。

I am using Jersey 2.0 implementation of JAX-RS webservice.

当我发送请求URL Http：// localhost / test / 时，请求标头是也通过了（暂时，虽然Firefox插件 - 硬编码）。

When I send the request URL Http://localhost/test/, the request headers are also passed (for the time being, though Firefox plugin - hardcoding them).

收到该URL的请求后，将调用以下方法：

On receiving the request for that URL, the following method is invoked:

@GET
@Produces(MediaType.APPLICATION_JSON)
public UserClass getValues(@Context HttpHeaders header) {
    MultivaluedMap<String, String> headerParams = header.getRequestHeaders();
    String userKey = "name";
    headerParams.get(userKey);

    // ...

    return user_object;
}

我怎样才能做到这一点？任何指针都会很棒！

How may I achieve this? Any pointers would be great!

推荐答案

只需注入 @Context HttpServletResponse响应作为方法论证。更改该标题

Just inject a @Context HttpServletResponse response as a method argument. Change the headers on that

@Produces(MediaType.APPLICATION_JSON)
public UserClass getValues(@Context HttpHeaders header, @Context HttpServletResponse response) {
    response.setHeader("yourheadername", "yourheadervalue");
    ...
}
