.net 5 获取用户真实IP(nginx)

环境 centos，docker，nginx，.net 5

1. 配置Nginx

   server {
        listen 80;
        server_name www.xxx.cn;
        location / {
            proxy_set_header Host $host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header REMOTE-HOST $remote_addr;
            proxy_set_header X-Forwarded-For $remote_addr; #为防止Ip伪造 如多个代理在最外层设置 remote_addr 其他代理设置$proxy_add_x_forwarded_for;
            proxy_pass http://localhost:xxx/;
        }
        error_page   500 502 503 504  /50x.html;
    }

修改完成后nginx -s reload 重新加载配置文件
2. 代码添加配置

  app.UseForwardedHeaders(new ForwardedHeadersOptions
      {
         ForwardedHeaders = ForwardedHeaders.XForwardedFor | ForwardedHeaders.XForwardedProto
      });

3. 使用原始方法获取IP地址
var ip = context.HttpContext.Connection.RemoteIpAddress.ToString()
