Question

嗨，我之前一直在尝试使用Apache进行此操作，但没有成功。我决定改用Nginx。

我正在尝试建立以下内容，

客户端<-wss-> Nginx <-ws-> Node.js

似乎很简单，但是我没有成功。我不断收到错误301。

我的客户端方面很简单

const connection = new WebSocket('wss://' + location.host + '/ws');

服务器端是

const ws = new WebSocket.Server({port: 8080});

Nginx配置文件是

server {
    server_name example.com;
    listen 443 ssl; # managed by Certbot

          return 301 https://$host$request_uri;
     } # managed by Certbot

     listen 80;

     server_name example.com;
     return 404; # managed by Certbot
}

我已经看到了许多有关websockets配置设置的文章，而我所没有的绝对可以。但是，无论我多么努力，它都不起作用。

Answer 1

我知道了，

问题是我将Websocket设置为端口8080，但是我的proxy_pass被设置为端口3000。

解决方案是使它们都在同一端口上。

对于应用服务器

const ws = new WebSocket.Server({port: 3001});

并使Nginx在/ ws下具有相同的端口，

proxy_pass http://localhost:3001;

通过Nginx反向代理使用Node.js保护Websockets的安全-错误301
