Node.js 通过php gear从托管的客户端连接到socket.io？-openshift

我正在尝试做一些相对简单的事情，至少是为了让事情开始。我有两个gear托管在openshift上，一个php-5.4和一个node.jsgear。我的客户端文件是从PHPGear托管的，但我正在尝试设置一个到节点服务器的socket.io连接

我意识到这会带来CORS问题 我尝试过在（许多）其他事情中更新标题，但运气不好。为了测试，我只使用socket.io

我不断地发现这个错误：

GET http://www.domain.com/socket.io/?EIO=3&transport=polling&t=1416040246016-0 404 (Not Found)`

如果我从通过express托管的index.html文件进行连接，它确实可以工作

我对node比较陌生，所以如果我在如何处理这个问题的假设中犯了一些错误，请原谅

这是代码

服务器端：

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

var server = function(){

var strt = this;

strt.setHeaders = function(){

  app.use(function (req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', 'http://www.domain.com:8000,
    http://domain.com:8000, http://node-domain.rhcloud.com:8000');

    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
    next();
  });
}

strt.setupVariables = function() {
  strt.ipaddress = process.env.OPENSHIFT_NODEJS_IP;
  strt.port      = process.env.OPENSHIFT_NODEJS_PORT || 3000;

  if (typeof strt.ipaddress === "undefined") {

      console.warn('No OPENSHIFT_NODEJS_IP var, using 127.0.0.1');
      strt.ipaddress = "127.0.0.1";
  };
}

strt.createRoutes = function() {

  app.get('/', function(req, res){
    res.sendfile(__dirname + '/index.html');
  });

}

strt.ioServer = function() {
  io.on('connection', function(socket){
    socket.on('chat message', function(msg){
      io.emit('chat message', msg);
    });
  });
}

strt.initializeServer = function() {

  http.listen(strt.port, strt.ipaddress, function(){
    console.log('listening on *:8000');
  });
}

}

var Start = new server();
Start.setHeaders();
Start.setupVariables();
Start.createRoutes();
Start.ioServer();
Start.initializeServer();

<script src="http://node-metagenome.rhcloud.com:8000/socket.io/socket.io.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>
  var socket = io().connect("http://node-domain.rhcloud.com:8000");

    socket.emit('chat message', $('#m').val());
    $('#m').val('');
    return false;
  });
  socket.on('chat message', function(msg){
    $('#messages').append($('<li>').text(msg));
  });
</script>

var socket = io().connect("http://node-domain.rhcloud.com:8000");

var socket = io("http://node-domain.rhcloud.com:8000");

客户端：

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

var server = function(){

var strt = this;

strt.setHeaders = function(){

  app.use(function (req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', 'http://www.domain.com:8000,
    http://domain.com:8000, http://node-domain.rhcloud.com:8000');

    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');

strt.setupVariables = function() {
  strt.ipaddress = process.env.OPENSHIFT_NODEJS_IP;
  strt.port      = process.env.OPENSHIFT_NODEJS_PORT || 3000;

  if (typeof strt.ipaddress === "undefined") {

      console.warn('No OPENSHIFT_NODEJS_IP var, using 127.0.0.1');
      strt.ipaddress = "127.0.0.1";
  };

      io.emit('chat message', msg);
    });
  });
}

strt.initializeServer = function() {

  http.listen(strt.port, strt.ipaddress, function(){
    console.log('listening on *:8000');
  });
}

}

var Start = new server();
Start.setHeaders();
Start.setupVariables();
Start.createRoutes();
Start.ioServer();
Start.initializeServer();

<script src="http://node-metagenome.rhcloud.com:8000/socket.io/socket.io.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>
  var socket = io().connect("http://node-domain.rhcloud.com:8000");

  socket.on('chat message', function(msg){

  });
</script>

var socket = io().connect("http://node-domain.rhcloud.com:8000");

var socket = io("http://node-domain.rhcloud.com:8000");

var socket=io（）。连接（“http://node-domain.rhcloud.com:8000");
$（'form'）。提交（函数（）{
emit（'chat message'，$（'#m'）.val（））；
$（'m'）.val（''）；
返回false；
});
socket.on（'chat message'，函数（msg）{
$（“#消息”）.append（$（“
”）.text（msg））；
});

好的，我想出来了。这是一个相对较小的变化

而不是：

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

var server = function(){

var strt = this;

strt.setHeaders = function(){

  app.use(function (req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', 'http://www.domain.com:8000,
    http://domain.com:8000, http://node-domain.rhcloud.com:8000');

    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
    next();
  });
}

strt.setupVariables = function() {
  strt.ipaddress = process.env.OPENSHIFT_NODEJS_IP;
  strt.port      = process.env.OPENSHIFT_NODEJS_PORT || 3000;

  if (typeof strt.ipaddress === "undefined") {

      console.warn('No OPENSHIFT_NODEJS_IP var, using 127.0.0.1');
      strt.ipaddress = "127.0.0.1";
  };
}

strt.createRoutes = function() {

  app.get('/', function(req, res){
    res.sendfile(__dirname + '/index.html');
  });

}

strt.ioServer = function() {
  io.on('connection', function(socket){
    socket.on('chat message', function(msg){
      io.emit('chat message', msg);
    });
  });
}

strt.initializeServer = function() {

  http.listen(strt.port, strt.ipaddress, function(){
    console.log('listening on *:8000');
  });
}

}

var Start = new server();
Start.setHeaders();
Start.setupVariables();
Start.createRoutes();
Start.ioServer();
Start.initializeServer();

<script src="http://node-metagenome.rhcloud.com:8000/socket.io/socket.io.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>

  });
</script>

var socket = io().connect("http://node-domain.rhcloud.com:8000");

var socket = io("http://node-domain.rhcloud.com:8000");

应该是：

var app = require('express')();
var http = require('http').Server(app);
var io = require('socket.io')(http);

var server = function(){

var strt = this;

strt.setHeaders = function(){

  app.use(function (req, res, next) {
    res.setHeader('Access-Control-Allow-Origin', 'http://www.domain.com:8000,
    http://domain.com:8000, http://node-domain.rhcloud.com:8000');

    res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
    res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
    next();
  });
}

strt.setupVariables = function() {
  strt.ipaddress = process.env.OPENSHIFT_NODEJS_IP;
  strt.port      = process.env.OPENSHIFT_NODEJS_PORT || 3000;

  if (typeof strt.ipaddress === "undefined") {

      console.warn('No OPENSHIFT_NODEJS_IP var, using 127.0.0.1');
      strt.ipaddress = "127.0.0.1";
  };
}

strt.createRoutes = function() {

  app.get('/', function(req, res){
    res.sendfile(__dirname + '/index.html');
  });

}

strt.ioServer = function() {
  io.on('connection', function(socket){
    socket.on('chat message', function(msg){
      io.emit('chat message', msg);
    });
  });
}

strt.initializeServer = function() {

  http.listen(strt.port, strt.ipaddress, function(){
    console.log('listening on *:8000');
  });
}

}

var Start = new server();
Start.setHeaders();
Start.setupVariables();
Start.createRoutes();
Start.ioServer();
Start.initializeServer();

<script src="http://node-metagenome.rhcloud.com:8000/socket.io/socket.io.js"></script>
<script src="http://code.jquery.com/jquery-1.11.1.js"></script>
<script>
  var socket = io().connect("http://node-domain.rhcloud.com:8000");
  $('form').submit(function(){
    socket.emit('chat message', $('#m').val());
    $('#m').val('');
    return false;

</script>

var socket = io().connect("http://node-domain.rhcloud.com:8000");

var socket = io("http://node-domain.rhcloud.com:8000");

我也不需要设置标题
