使Nginx代理仅升级Docker Compose堆栈中的信号器WebSocket连接

有没有办法只升级

nginx.conf

文件中的SignalR WebSocket连接而不复制整个部分

ASP.NET Core拒绝未升级的信号器连接，但是我在该ASP.NET Core项目上运行API，当请求的标题为“Connection:“upgrade”时，该API不会接受带有正文的POST请求

我当前的解决方案是复制我的

nginx.conf

文件中的“location”部分，如下所示。有更优雅的解决方案吗

谢谢

我的

找到了解决办法

因此，您可以在

nginx.conf

中编辑“proxy\u set\u header Connection”属性，以向前传递必要的值

nginx.conf

的重要部分如下：

location /shopvac {
    proxy_pass http://shopvac:80;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection $http_connection;
    proxy_set_header Host $host;
    proxy_cache_bypass $http_upgrade;
    rewrite ^/shopvac/(.*)$ /$1 break;
}
