Question

当我尝试将我的系统连接到nodeJs套接字（socket.io）时，我收到错误消息

WebSocket connection to 'ws://mysite.co/socket.io/?EIO=3&transport=websocket&sid=SkcmTj6P8_qAL_mSALBN' failed: Error during WebSocket handshake: Unexpected response code: 400

配置如下： nginx- v1.8.0

upstream node {
        ip_hash;
        server localhost:3001;
        server localhost:3002;
        server localhost:3003;
        server localhost:3004;
        server localhost:3005;
}

server {
        listen 80;
        server_name www.mysite.co
        root /var/www/mysite/web;
        rewrite ^/app\.php/?(.*)$ /$1 permanent;
        try_files $uri @rewriteapp;
        location @rewriteapp {
        rewrite ^(.*)$ /app.php/$1 last;
        }
        # Deny all . files
        location ~ /\. {
        deny all;
        }
        location ~ ^/(app|idan_dev)\.php(/|$) {
        fastcgi_split_path_info ^(.+\.php)(/.*)$;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index app.php;
        fastcgi_send_timeout 30;
        fastcgi_read_timeout 30;
        fastcgi_pass 127.0.0.1:9000;
        }
        # Statics
        location /(bundles|media) {
        expires 1d;

        try_files $uri @rewriteapp;
        }
        error_log /var/log/nginx-error.log;
        access_log /var/log/nginx-access.log;

        location ~ /socket.io {
                proxy_set_header X-Real-IP $remote_addr;
                proxy_pass http://node;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                proxy_read_timeout 150;
                access_log off;
        }

}

在nodejs部分我批准了任何一个（现在，为了测试这个特定的问题）

var app = require('express')();
var bodyParser = require('body-parser');
var redis = require('redis').createClient();
var server = require('http').createServer();
var io = require('socket.io').listen(server);
var sockets = [];
var request = require('request');

// these statements config express to use these modules, and only need to be run once
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: true }));

app.post('/data', function(req, res) {
  // do some stuff with data sent directly to node.
});

app.listen(parseInt( process.env.port ) + 1000); // set listening a port for port for the balancer.

module.exports = app;

// run HTTP server on this port
console.log('listening to port ' + ( parseInt( process.env.port ) - 3000 ));
server.listen(process.env.port); // setting multiple ports for same file 

// allow any user to authenticate.
io.set('authorization', function(handshake, callback)
{
  return callback(null, true);
});

io.sockets.on('connection', function(socket)
{
  var id = getUserId(socket);
  console.log('on connection id - ' + id);
  if( id === false) return;
  sockets[id] = socket;

  socket.on('disconnect', function()
  {
    var index = sockets.indexOf(socket);
    if (index != -1) {
      sockets.splice(index, 1);
    }
  });

});


function getUserId(socket) {
  // getting the id of the user..
  return '1';
}

我不知道它是否相关但网站本身是基于php的，只有套接字系统是基于nodejs的。我对nodejs和socket.io非常好，所以如果有任何数据丢失，请告诉我，我会添加它。
