我试图配置Nginx代理将请求传递给另一个服务器,只有当$request_body变量匹配特定的正则表达式.但它不适合我.

 server{
        listen 80 default;
        server_name www.applozic.com;

        location / {
                 proxy_set_header X-Real-IP $remote_addr;
                 proxy_set_header X-Forwarded-For $remote_addr;
                 proxy_set_header Host $http_host;

                if ($request_body ~* (.*)appId(.*)) {
                   proxy_pass http://apps.applozic.com;
                }
        }

}

请求正文是::

              {
               "applicationId": "appId","authenticationTypeId": 1,"enableEncryption": false,"notificationMode": 0,"deviceType": 4,}
