Websocket 代理背后的Web套接字

我有一个SpringBoot应用程序，WebSocket在Apache2后面运行。尝试连接时，我遇到以下错误：

• 服务器日志：

  Handshake failed due to invalid Upgrade header: null
  

• 客户端日志：

以下是Apache 2配置：

<IfModule mod_ssl.c>
<VirtualHost *:443>

谢谢你的帮助

您需要安装mod_proxy_wstunnel（mod_proxy和mod_ssl）。然后在Apache的配置中：

ProxyPass /ws2  ws://languageexchange.eu:92 keepalive=On
ProxyPassReverse /ws2  ws://languageexchange.eu:92
ProxyPass /wss2 wss://languageexchange.eu:92 keepalive=On
ProxyPassReverse /wss2  wss://languageexchange.eu:92

如果这是一台机器，最好设置127.0.0.1而不是languageexchange.eu，因此：

您在哪里托管服务器？在AWS上，当您在某些模式下使用ELB时，WebSocket支持存在问题。它只是Ubuntu的VPS。您的服务器托管在哪里？在AWS上，当您在某些模式下使用ELB时，WebSocket支持存在问题。这只是Ubuntu的VPS。
