Question

我正在尝试访问正在调用我的休息服务器的客户端ip，但我只是将null作为响应。 Web服务器正在运行，我可以从Web浏览器访问。

我试过

@Context HttpServletRequest

还有

@Context ContainerRequest请求
    request.getRequestHeader（ “HTTP_FORWARDED”）
    // HTTP_X_FORWARDED
    // HTTP_CLIENT_IP

但两种情况都没有成功，响应为空或空白。

HttpServletRequest提供了一个应该返回远程IP地址的getRemoteAddr()方法。请注意，代理或NATing可能会修改IP地址。

编辑：

解决方案是注入一个灰熊请求：

@GET
@Path("/test/")
@Produces(MediaType.APPLICATION_JSON)
public TestAddress test(@Context org.glassfish.grizzly.http.server.Request re) {
    System.out.println(re.getRemoteAddr());
    ...
}

这对我有用，但它完全依赖灰熊。
