在Jersey 2.22.2中获取客户端ip

本文介绍了在Jersey 2.22.2中获取客户端ip的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我正在尝试访问正在调用我的休息服务器的客户端ip，但是我只得到null作为响应.网络服务器正在运行，我可以通过网络浏览器进行访问.

I am trying to acess the clients ip that are calling my rest server but I only get null as a respons. The webserver is running and I can access is from the web browser.

我尝试过

@Context HttpServletRequest

@Context HttpServletRequest

还有

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

@Context ContainerRequest request request.getRequestHeader("HTTP_FORWARDED") //HTTP_X_FORWARDED //HTTP_CLIENT_IP

但没有成功，响应为空或为空.

But neither whit sucess, the response is null or blank.

设置

• Jersey v:2.22.2
• Grizzly v:2.3.22
• Java v:8

Rest.java

import javax.ws.rs.GET; import javax.ws.rs.Path; import javax.ws.rs.PathParam; import javax.ws.rs.Produces; import javax.ws.rs.QueryParam; import javax.ws.rs.container.ContainerRequestContext; import javax.ws.rs.core.Context; import javax.ws.rs.core.MediaType; import javax.ws.rs.core.Request; import javax.ws.rs.core.UriInfo; @Path("/rest") public class Rest { @GET @Path("/test/") @Produces(MediaType.APPLICATION_JSON) public TestAddress test(@Context HttpServletRequest re){ System.out.println(re.getRemoteAddr()); TestAddress adr = new TestAddress(); adr.setAge(32); adr.setName("Fidde"); adr.setSurename("Lass"); //System.out.println(uriInfo.getBaseUri()); return adr; }

main.java

import org.glassfish.grizzly.http.server.HttpServer; import org.glassfish.jersey.grizzly2.httpserver.GrizzlyHttpServerFactory; import org.glassfish.jersey.server.ResourceConfig; import java.io.IOException; import java.URI; public class Main { // Base URI the Grizzly HTTP server will listen on public static final String BASE_URI = "localhost:8080/myapp/"; /** * Starts Grizzly HTTP server exposing JAX-RS resources defined in this application. * @return Grizzly HTTP server. */ public static HttpServer startServer() { // create a resource config that scans for JAX-RS resources and providers // in com.example package final ResourceConfig rc = new ResourceConfig().packages("com.example"); // create and start a new instance of grizzly http server // exposing the Jersey application at BASE_URI return GrizzlyHttpServerFactory.createHttpServer(URI.create(BASE_URI), rc); } /** * Main method. * @param args * @throws IOException */ public static void main(String[] args) throws IOException { final HttpServer server = startServer(); System.out.println(String.format("Jersey app started with WADL available at " + "%sapplication.wadl\nHit enter to stop it...", BASE_URI)); System.in.read(); server.stop(); }

}

推荐答案

HttpServletRequest提供了一种getRemoteAddr()方法，该方法应返回远程IP地址. 请注意，代理或NAT可能会修改IP地址.

HttpServletRequest provides a getRemoteAddr() method that should returns the remote IP address. Note that proxying or NATing may modify the IP address.

解决方案是注入灰熊的请求:

The solution is to inject a grizzly request :

@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，但是完全依赖于灰熊.

This is working for me, but it is totally grizzly dependant.
