套接字.io对于Nginx+NodeJS,跨源请求只能部分工作

socket.io nginx node.js javascript

和一个服务器。取决于子域

现在我想用套接字.io来自另一个地方。 但当我发出声音或听到声音时,它就不起作用了。

我没有得到任何例外,但事件不会触发。

后端代码:

io.set('origins', '*:*');

io.on('connection', function (client) {
    console.log(client.id + " joined!"); //event fired

    client.on('helloworld', function () {
        console.log(client.id + " said hello!"); //event not fired
    });
}

前端代码:

var io = io("https://subdomain.example.com");
io.emit("helloworld");

Nginx脚本:

server{
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/subdomain.example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/subdomain.example.com/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot

    server_name subdomain.example.com;

    location / {
        limit_conn addr 10;
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_pass    http://127.0.0.1:7005/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
        proxy_set_header Access-Control-Allow-Origin "*";
        proxy_set_header Access-Control-Allow-Headers "origin, x-requested-with, content-type";
        proxy_set_header Access-Control-Allow-Methods "PUT, GET, POST, DELETE, OPTIONS";
    }
}

我尝试过的可能性:

Socket.io + NodeJS + Nginx + SSL

Cross-domain connection in Socket.IO

Socket.io + Node.js Cross-Origin Request Blocked
