Java 来自 REST 的访问请求对象

Access Request object from REST

提问by qnoid

Is it possible to access the Request object in a REST method under JAX-RS?

是否可以在 JAX-RS 下以 REST 方法访问请求对象？

I just found out

我刚刚发现

@Context Request request;

On JAX-RS you must annotate a Requestparameter with @Context:

在 JAX-RS 上，您必须使用@Context注释请求参数：

 @GET  
 public Response foo(@Context Request request) {

 }

Optionally you can also inject:

（可选）您还可以注入：

• UriInfo
• HttpHeaders
• SecurityContext
• HttpServletRequest

• 信息
• 头文件
• 安全上下文
• HttpServletRequest

To elaborate on @dfa's answer for alternatives, I find this to be simpler than specifying the variable on each resource method signature:

为了详细说明@dfa 对替代方案的回答，我发现这比在每个资源方法签名上指定变量更简单：

public class MyResource {

  @Context
  private HttpServletRequest httpRequest;

  @GET  
  public Response foo() {  
    httpRequest.getContentType(); //or whatever else you want to do with it
  }
}
