java - 如何在java中连接到gtalk？

转载作者：搜寻专家更新时间：2023-10-31 20:31:03

我正在尝试用 Java 编写一个小型 XMPP gtalk 客户端。我知道有很多库可以帮助你，但 RFC 太容易理解了，所以我决定自己写一个客户端。我知道 gtalk 服务器是 talk.google.com:5222 但是当我尝试这个小程序时我得到了这个结果:

 HTTP/1.1 302 Found
Location: http://www.google.com/talk/
Content-Type: text/html
Content-Length: 151

<HTML><HEAD><TITLE>302 Moved</TITLE></HEAD><BODY><H1>302 Moved</H1>The document has moved <A HREF="http://www.google.com/talk/">here</A>.</BODY></HTML>

我也尝试连接指定的位置，但它不起作用。这是我在 Java 中的代码:

    package fr.grosdim.myjabber;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;

import javax.net.ssl.SSLPeerUnverifiedException;
import javax.net.ssl.SSLSocketFactory;

/**
 * Hello world!
 * 
 */
public class App {
    public static void main(String[] args) {
        SSLSocketFactory factory = (SSLSocketFactory) SSLSocketFactory
                .getDefault();
        try {


            Socket s = new Socket("talk.google.com", 5222);

            PrintWriter out = new PrintWriter(s.getOutputStream());
            out.println("<?xml version=\\'1.0\\' encoding=\\'utf-8\\' ?>");
            out
                    .println("<stream:stream to='talk.google.com:5222' "
                            + "xmlns='jabber:client'"
                            + " xmlns:stream='http://etherx.jabber.org/streams' version='1.0'>");
            out.flush();

            BufferedReader reader = new BufferedReader(new InputStreamReader(s
                    .getInputStream()));

            String line;
            while ((line = reader.readLine()) != null) {
                System.out.println(line);

            }

            out.println("</stream>");
            s.close();

        } catch (SSLPeerUnverifiedException e) {
            System.out.println(" Erreur d'auth :" + e.getLocalizedMessage());
        } catch (UnknownHostException e) {
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (Exception e) {
            System.out.println(e.getLocalizedMessage());
        }

    }
}
