用于Node.js的代理

Question

我试图使用Node.js读取凤凰频道使用npm包凤凰频道。凤凰频道在websockets之上是多路复用的。我在我的菲尼克斯网络服务器前使用了一个NGINX代理，所以对于NGINX来说，它只是一个websocket。

凤凰频道可以很好地进入网页，因为您可以看到这里 (您将在网页中看到数据)。

在我的内部网络上，nodejs也可以正常工作。

​

​

test_chan.js (具有显式IP和端口)：

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，如果我用域名替换了外接IP:端口地址，并从外部运行它，它就不能工作(上面的脚本唯一的区别是URL)：

test_chan.js (通过域名和我的NGINX代理)：

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，suprabonds.com websockets可以通过代理在浏览器中正常工作，但不作为nodejs脚本工作。

以下是suprabonds.com的nginx：

站点-启用相关服务器部分：

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


}

知道我做错了什么吗？

火狐是那些运行良好的。其他的(其中有30178个)是来自不工作的Node.js脚本(也就是使用域名的脚本)。位于同一位置的error.log文件为空。

请注意，我也使用noip动态域名系统。

如果将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")

它会连接
