PHP websockets在wss://上不工作

Question

我把我的网站移到了https://.在http to socket上有一个通过ws: //sitename.com: 3003的连接，现在有必要在wss: //sitename.com: 3003上提供它们。我该怎么做呢？谢谢。

PHP：

$loop   = React\EventLoop\Factory::create();
$context = new React\ZMQ\Context($loop);
$pull = $context->getSocket(ZMQ::SOCKET_PULL);
$pull->bind('tcp://127.0.0.1:3004');
$pull->on('message', array($pusher, 'onMessage'));

$webSock = new React\Socket\Server($loop);
$webSock->listen(3003, '0.0.0.0');
$webServer = new Ratchet\Server\IoServer(
  new Ratchet\Http\HttpServer(
    new Ratchet\WebSocket\WsServer(
      new Ratchet\Wamp\WampServer(
        $pusher
      )
    )
  ),
  $webSock
);

$loop->run();

JS：

window.phpSocket = new ab.Session('wss://sitename.com:3003',

nginx：

server {
    listen   443 ssl;
    keepalive_timeout   70;

    client_max_body_size    500M;
    root /var/www/path/to/site/root;
    index index.php;
    server_name sitename.com;
    gzip_static on;
    gzip            on;
    gzip_min_length 1000;
    gzip_proxied    expired no-cache no-store private auth;
    gzip_types      text/plain application/xml text/css text/javascript application/javascript;


    ssl                     on;
    ssl_certificate         /etc/letsencrypt/live/sitename.com/fullchain.pem;
    ssl_certificate_key     /etc/letsencrypt/live/sitename.com/privkey.pem;
    ssl_session_cache       shared:SSL:10m;
    ssl_session_timeout     10m;

因为您的nginx conf没有指定如何将您的客户端wss转发到您在3003处监听的服务器端口。

您应该将其添加到nginx.conf中的服务器块中

location /wss/ {
    proxy_pass http://localhost:3003;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
}

并将您的Js代码更改为：

window.phpSocket = new ab.Session('wss://sitename.com/wss/',
