服务器反推技术，flex flash socket java javascript

感谢大家的回答：

问题已经解决了：

如下：

服务器代码：

package JSocket;

?

?

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.OutputStreamWriter;

import java.io.PrintWriter;

import java.net.ServerSocket;

import java.net.Socket;

import java.util.ArrayList;

import java.util.List;

import java.util.concurrent.ExecutorService;

import java.util.concurrent.Executors;

?

public class Server {

private static final int PORT = 3000; // 端口号

private static List<Socket> list = new ArrayList<Socket>(); // 保存连接对象

private ExecutorService exec;

private ServerSocket server;

?

public static void main(String[] args) {

new Server();

}

public Server() {

try {

server = new ServerSocket(PORT);

exec = Executors.newCachedThreadPool();

System.out.println("服务器已启动！");

Socket client = null;

while (true) {

client = server.accept(); // 接收客户连接

list.add(client);

exec.execute(new ChatTask(client));

}

} catch (IOException e) {

e.printStackTrace();

}

}

?

static class ChatTask implements Runnable {

private Socket socket;

private BufferedReader br;

private String msg="";

private String msg1="";

?

public ChatTask(Socket socket) throws IOException {

this.socket = socket;

br = new BufferedReader(new InputStreamReader(socket.getInputStream()));

}

?

public void run() {

new Thread(new Runnable() {

public void run() {

PrintWriter pw;

try {

pw = new PrintWriter(socket.getOutputStream(),true);

int i=0;

while(true){

msg="<cross-domain-policy><allow-access-from domain="" + "*" + "" to-ports="3000"/></cross-domain-policy>";

msg1=i+"你好！";

if(i==0){//如果客户端是第一次访问服务器那么发送，安全策略允许文件，这必须的否则其余的免谈

pw.println(msg);

pw.flush();

}

else{//向客户端发送数据

pw.println(msg1);

pw.flush();

}

try {

Thread.sleep(1000);

} catch (InterruptedException e) {

e.printStackTrace();

}

i++;

}

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

}).start();

}

}

}

客户端代码：

js代码中的swf文件是flexbuilder编译之后的文件，这个要怎么弄到稍微会点flex应该就能明白了！不多说了！

在网上找了这个叫服务器反推技术：具体实现的方式不一样，我用的是java作为tcp/ip服务器，flash作为客户端接收，然后flash和js通信达到可以将服务器的数据反推到html中的目的！有很多问题以上的代码都应该解决了！

遇到问题：

flash安全策略问题！

数据乱码问题！

再次感谢大家！
