使用Android客户端进行socketIO时出现SocketIO异常

概述我正在构建一个Android聊天应用程序.我在服务器端使用nodejs并尝试实现androidclientforsocketIO.我收到了SocketIO异常.这些代码有什么问题？服务器varhttp=require('http'),fs=require('fs');varapp=http.createServer(function(req,res){res.end();

我正在构建一个Android聊天应用程序.我在服务器端使用nodeJs并尝试实现android client for socketIO.我收到了SocketIO异常.这些代码有什么问题？

服务器

var http = require('http'),fs = require('fs');var app = http.createServer(function (req, res) {res.end();                                                      }).Listen(8000, '127.0.0.1');var io = require('socket.io').Listen(app);io.sockets.on('connection', function(socket) {socket.on('echo', function(data) {socket.emit('echoback', data);});});

客户

解决方法:

检查是否将INTERNET PERMISSION置于Manifest中.如果你不这样做,请：

<uses-permission androID:name="androID.permission.INTERNET"/>
