我正在尝试将simple node js (socket.io) 服务器与我的android 应用程序 进行通信 我正在使用Gottox socket.io-java-client lib 作为客户端转换为 jar 文件但它总是返回错误(找不到握手文件时出错)我正在使用 wifi 在本地网络上的移动设备上测试应用程序我的 ip 是 192.168.1.69 我已经通过网络测试了服务器通信，它工作正常
node js socket server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
});

最佳答案
问题已解决(某种程度上)，此处:Android developpement, Gottox socket.io-java-client: file not fount Exception /socket.io/1/
(尝试使用早期版本的 socket.io - 首先从 node_modules 中删除 socket.io 文件夹，然后使用此命令安装旧版本，例如 0.9.16:npm install socket.io@0.9.16)
关于java - Gottox socket.io-java-client “握手时出错，由 : java. io.FileNotFoundException : http://192. 168.1.69 :8080/socket. io/1/引起，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/24081179/
