Question

我正在AWS Elastic Beanstalk上运行socket.io node.js应用。我没有包括express.js。

显然，Elastic Beanstalk上的Nginx代理在没有手动配置的情况下无法通过TCP连接。

我正在尝试通过我的Android客户端或浏览器连接它。

我已尝试过互联网上的每个解决方案，但我得到502 Bad gateway或超时错误。

我是否应该将AWS Elastic Beanstalk负载均衡器更改为接受TCP而非HTTP？

我的node.js应用正在侦听端口3000（硬编码）。在localhost上运行得很好。

var server = require('http').createServer(handleRequest);
var io = require('socket.io')(server);

function handleRequest(request, response)
{
    response.end('It Works!! Path Hit: ' + request.url);
}

io.on('connection', function (socket)
{
    console.log('a user connected');

    socket.on('disconnect', function ()
    {
        console.log('user disconnected');
    });

    socket.on('chat message', function (msg)
    {
        console.log('message received on server: ' + msg);

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

server.listen(3000, function ()
{
    console.log("Server listening on port:", 3000); //Callback triggered when server is successfully listening. Hurray!
});

这是我的package.json

{
  "name": "qurba-messaging-backend",
  "version": "0.0.1",
  "scripts": {
    "start": "node main.js"
  },
  "dependencies": {
    "socket.io": "^1.4.6"
  }
}

这是我的nginx配置https://gist.github.com/RobinBuschmann/c42a413ecedee463e5bd8e613ddd8d04
