使用来自certbot的ssl将websocket nginx代理设置为node.js

Question

我想让我的使用ws npm模块的节点应用程序使用ssl websockets（wss：//）。最重要的是，我想使用在certbot中使用nginx设置的ssl。

我让节点websocket监听端口8080，尽管我可以直接连接到该端口，但是由于该站点是通过ssl服务的，因此由于未加密，因此会引发错误。

对于客户端javascript，您可以将呼叫路由到wss：//examplesite.com/websocket

• 在nginx配置中，将标头设置为”，以建立关闭连接。
• 为您的websocket端口创建上游
• 添加/ websocket位置

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
}

upstream websocket {
   server 127.0.0.1:8080;
}

server {
    server_name examplesite.com;
    location /websocket {
            proxy_pass http://websocket;
            proxy_http_version 1.1;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection $connection_upgrade;
            proxy_set_header Host $host;
    }

# after this is just an example of the rest of the nginx config for a node server on 8675
# that has a static build directory
    location / {
        proxy_pass http://127.0.0.1:8675;
        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;
        proxy_set_header X-Real-IP $remote_addr;
    }
    location ~ \.(gif|jpg|png|js|txt|html|mp3|css|woff2)$ {
        root /root/examplesite.com/build/;
        expires 30d;
    }

    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/examplesite.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/examplesite.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

}

您可以使用https://www.npmjs.com/package/wscat测试您的本地ws：// ...：8080和您的wss：//.../websocket连接
