此代码在localhost上完美运行，但在将其推送到云代工厂后无效...
这是服务器代码：
var net = require("net"),
JsonSocket = require("json-socket");
var port = process.env.VCAP_APP_PORT || process.env.PORT || '3000';
var server = net.createServer();
//DEFINE A JSON MODEL FOR TAG DATAS
var tags = [];
var ids = [1, 2, 3, 4, 5];
var date = new Date();
for (var i = 0; i < ids.length; i++) {
tags.push({id: ids[i],
timestamp: date,
position: [0, 0]
});
console.log(tags[i]);
}
function update(tags, i){
var now = new Date();
tags[i].timestamp = now;
if(tags[i].position[0] < 180 && tags[i].position[0] > -180){
tags[i].position[0] += Math.floor(Math.random()*3 - 1);
} else {
tags[i].position[0] = 0;
}
if(tags[i].position[1] < 180 && tags[i].position[1] > -180){
tags[i].position[1] += Math.floor(Math.random()*3 - 1);
} else {
tags[i].position[1] = 0;
}
}
server.listen(port);
console.log('Socket emitting on port: '+port);
server.on("connection", function(socket) {
console.log('New connection');
socket = new JsonSocket(socket);
console.log('JsonSocket created');
var i = 0;
socket.on("message", function(message) {
console.log('Mesaage received');
if(message.command == "newData"){
//remplir l'array
//message.data.position[0] --> x
}else{
streamInterval = setInterval(function() {
if(i<tags.length){
socket.sendMessage(JSON.stringify(tags[i]));
update(tags, i);
i++;
} else {
i = 0;
socket.sendMessage(JSON.stringify(tags[i]));
update(tags, i);
i++;
}
}, 1000); //SET INTERVAL DURATION IN MS
}
});
});
所以基本上我只是在等待开始连接的消息。之后，我将所有数据发送给客户端。
这是我客户的代码：
var net = require('net'),
JsonSocket = require('json-socket');
var port = 80;
var host = 'locationserver.apps.eu01.cf.canopy-cloud.com';
var socket = new JsonSocket(new net.Socket());
socket.connect(port, host);
socket.on('connect', function(err) {
console.log('client connected');
socket.sendMessage({command: 'start'});
console.log('message sended');
socket.on('message', function(msg) {
console.log(msg);
});
});
在localhost上，这是结果：
client connected
message sended
{"id":1,"timestamp":"2016-04-12T12:36:33.491Z","position":[0,0]}
{"id":2,"timestamp":"2016-04-12T12:36:33.491Z","position":[0,0]}
{"id":3,"timestamp":"2016-04-12T12:36:33.491Z","position":[0,0]}
{"id":4,"timestamp":"2016-04-12T12:36:33.491Z","position":[0,0]}
{"id":5,"timestamp":"2016-04-12T12:36:33.491Z","position":[0,0]}
但如果我将服务器放在云代工厂上，我就明白了：
client connected
message sended
然后停止......
我没有错误..没有。但在云代工厂我的调试消息说客户端连接不会出现！ （console.log（'New Connection'）第38行......）
我有一些联系，但我想这只是云代工厂的保持系统..
有人有关于此的一些信息吗？
云代工刚刚说使用：var port = process.env.VCAP_APP_PORT || process.env.PORT || '3000';我想我必须在80端口绑定我的客户端，但我不确定...
谢谢

你应该记录
var port = process.env.VCAP_APP_PORT || process.env.PORT || '3000';检查部署端口时使用的端口。
在客户端，发生的情况是端口可能是错误的（端口80）。
它没有在您的客户端显示任何错误，因为您没有打印它：
socket.on('connect', function(err) {
if (err) {
console.log(err);
}
console.log('client connected');
socket.sendMessage({command: 'start'});
console.log('message sended');
socket.on('message', function(msg) {
console.log(msg);
});
});
可能发生的事情是它无法连接并发送消息，因此它会超时。
编辑：
在查看云代工厂文档之后，它写了流量重定向到端口80（http）或443（https）重定向到环境端口。

我现在正在使用socket.io，一切都很完美 请参阅http://socket.io/和示例：http://socket.io/get-started/chat/
云代工厂的问题是一切都用过http！你还不能使用TCP ......他们正在研究它。
