通过SSL使用Socket.io Node.js的错误网关错误

我以前有一个Socket.io脚本运行良好的http，但升级到https已经打破了它。 我已经在服务器上安装了证书，但没有运气。 服务器设置的代码是：

var https = require('https'), fs = require('fs'); var options = { key: fs.readFileSync('/etc/nginx/ssl/default/54082/server.key'), cert: fs.readFileSync('/etc/nginx/ssl/default/54082/server.crt') }; var app = https.createServer(options); var io = require('socket.io').listen(app); 

但是，在Web浏览器中，页面无法连接到它，并且控制台显示the server responded with a status of 502 (Bad Gateway)响应。

任何想法，如果脚本设置是错误的？ 或者也许在Nginx的设置？

非常感谢

• Socket.io无法在nginx + node.js + php应用程序中连接
• 部署本地nginx服务器到公共ubuntu 16.04
• Laravel + AngularJS Nginx路由
• 如何更新nginx模块运行时的内部状态？
• 我如何使用nginx 1.9.5作为gRPC的反向代理？

编辑：我用来连接的前端代码：

 <script type="text/javascript" src="https://socket.example.com/socket.io/socket.io.js"></script> <script> var io = io('https://socket.example.com', { secure: true }); </script> 

编辑:: Nginxconfiguration：

 # FORGE CONFIG (DOT NOT REMOVE!) include forge-conf/socket.example.co.uk/before/*; server { listen 443 ssl; server_name socket.example.co.uk; root /home/forge/socket.example.co.uk; # FORGE CONFIG (DOT NOT REMOVE!) include forge-conf/socket.example.co.uk/server/*; location / { proxy_pass https://socket.example.co.uk:3000; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection 'upgrade'; proxy_set_header Host $host; proxy_cache_bypass $http_upgrade; } } # FORGE CONFIG (DOT NOT REMOVE!) include forge-conf/socket.example.co.uk/after/*; 

 var socket = io.connect('dev.somedomain.com:3000',{secure:true}); 

 var fs = require('fs'), https = require('https'), config = JSON.parse(fs.readFileSync('./config.json','utf-8')), serverOpts = { key: fs.readFileSync(config.server.key), cert: fs.readFileSync(config.server.cert) }, server = https.createserver(serverOpts,function(req,res){}), io = require('socket.io').listen(server); io.on('connection', function(socket){ console.log('houston, we have lift off'); }); server.listen(config.port, function(){ log('listening on *:%d',config.port); }); 

  proxy_pass https://socket.example.co.uk:3000;
