Nginx websocket代理Node.js

Question

我正在尝试使用Node.js来读取凤凰频道使用npm包凤凰频道。凤凰频道是在websockets之上复用的。我在我的phoenix服务器前面使用的是NGINX代理，所以对于NGINX来说，它只是一个websocket。

凤凰频道在网页上运行良好，正如您在此处看到的（您将在网页中看到数据）。

它也可以从我的内部网络上的nodejs正常工作：

const { Socket } = require('phoenix-channels')

let socket = new Socket("https://192.168.1.113:4445/socket")

socket.connect()

// Now that you are connected, you can join channels with a topic:
let channel = socket.channel("room:lobby", {})

channel.on("new_msg", payload => {
  console.log(`${payload.body}`);
});

channel.join()
  .receive("ok", resp => { console.log("Joined successfully", resp) })
  .receive("error", resp => { console.log("Unable to join", resp) })

但是，如果我用域名替换显式IP： PORT地址，并从外部运行它，它就不起作用了（这里与上面的脚本的唯一区别是URL）：

const { Socket } = require('phoenix-channels')

let socket = new Socket("https://suprabonds.com/socket")

socket.connect()

// Now that you are connected, you can join channels with a topic:
let channel = socket.channel("room:lobby", {})

channel.on("new_msg", payload => {
  console.log(`${payload.body}`);
});

channel.join()
  .receive("ok", resp => { console.log("Joined successfully", resp) })
  .receive("error", resp => { console.log("Unable to join", resp) })

因此，websockets suprabonds.com 通过代理在浏览器中工作正常，但不能用作nodejs脚本。

以下是我在suprabonds.com的nginx conf:

server {
    server_name suprabonds.com www.suprabonds.com;
    
    location / {
        proxy_pass  http://localhost:4445;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }


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


}

知道我哪里做错了吗？

火狐是那些工作正常的。其他的（301 178）是来自非工作Node.js脚本的（即使用域名的）。同一位置的error.log文件是空的。
请注意，我也在使用noip动态dns。

如果您将URL更改为：

let socket = new Socket("wss://suprabonds.com/socket/websocket?token=undefined")

或

let socket = new Socket("wss://suprabonds.com/socket/websocket?vsn=1.0.0")

它将连接
