WebSocket通过SSL与Apache反向代理 [英] WebSocket through SSL with Apache reverse proxy

问题描述

在客户端，我正在尝试建立wss连接:

On the client side, I am trying to establish the wss connection:

var ws = new WebSocket("wss://wsserver.com/test")

并返回错误:

WebSocket connection to 'wss://wsserver.com/test' failed: Error during WebSocket handshake: Unexpected response code: 400

完整的标头是:

请求标头

GET wss://wsserver.com/test HTTP/1.1
Host: wsserver.com

Pragma: no-cache

服务器端在Apache反向代理后面的端口8888上运行.这是Apache的配置:

The server side is running on go at port 8888 behind an Apache reverse proxy. This is the Apache configuration:

<VirtualHost *:443>
        ServerName website.com

        ProxyPreserveHost On
        ProxyRequests Off
        ProxyPass "/" "wss://localhost:8888/"

mod_proxy 和 mod_proxy_wstunnel 已安装.

这里缺少什么吗?似乎请求已通过，但未建立连接.

Is there something missing here? It seems like the request goes through but no connection is established.

推荐答案

我最终通过为虚拟主机使用此配置解决了此问题，该配置使用HTTP标头过滤请求:

I ended up solving this problem by using this configuration for the virtual host, which filters requests using the HTTP headers:

<VirtualHost *:443>
    ServerName website.com

    RewriteEngine On

    # When Upgrade:websocket header is present, redirect to ws
    # Using NC flag (case-insensitive) as some browsers will pass Websocket
    RewriteCond %{HTTP:Upgrade} =websocket [NC]
    RewriteRule ^/ws/(.*)    wss://localhost:8888/ws/$1 [P,L]

    # All other requests go to http
    ProxyPass "/" "http://localhost:8888/"
