GottoxSocket.IO-java-Client在握手时出错: http://192.168.1.69:8080/socket.io/1/ : java.io.FileNotFoundException：
提问于 2014-06-06 11:50:17
我正在尝试将简单节点js (socket.io)服务器与我的android应用程序通信，我使用Gottox socket.io-java-client lib作为客户端，但它总是返回错误(当握手文件未找到时出错)，我使用wifi在本地网络上测试该应用程序，我的ip是192.168.1.69，我已经通过web测试了服务器通信，运行良好。
节点js套接字服务器代码
var mongo = require('mongodb').MongoClient,
Client = require('socket.io').listen(8080).sockets;
mongo.connect('mongodb://192.168.1.69/chat',function(err, db){
if(err) throw err;
Client.on('connection',function(socket){
//get mongo db collection
console.log("Connected to server");
var col = db.collection("messages"),
sendStatus = function(s){
socket.emit('status',s);
};
//emit all messages
col.find().limit(100).sort({_id:1}).toArray(function(err, res){
if(err) throw err;
socket.emit("output",res);
});
//wait for input
socket.on('input',function(data){
console.log("data-------> name: "+data.name+" message: "+data.message);
//insert into mongodb server
//json data from client
var name = data.name,
message = data.message,
whitespacePattern = /^\s*$/;
if(whitespacePattern.test(name) || whitespacePattern.test(message)){
sendStatus("Name and Message is required.");
console.log("invalid data");
}else{
col.insert({name: name,message:message},function(){
//emit latest to all clients
Client.emit('output',[data]);
sendStatus({
message:"message sent",
clear:true
});
});
}
//on input
});
//on connection
});
//mongo db connect
});安卓客户端的代码

问题解决(某种程度上)，这里：Android developpement, Gottox socket.io-java-client: file not fount Exception /socket.io/1/
(尝试使用socket.io的早期版本-首先从node_modules中删除socket.io文件夹，然后使用以下命令安装旧版本，例如0.9.16 :NPMInstallSocket.IO@0.9.16)

使用这个新库在Java上使用socket.io 1.0
