   The APISIX's  access log only support NGINX's variable and the access.log look like this with the config:
   
   ```
    http:
       enable_access_log: true         # enable access log or not, default true
       access_log: logs/access.log
       access_log_format: '{"status": $status,"body_bytes_sent": $upstream_response_length,"scheme":"$scheme","http_user_agent":"$http_user_agent","request_length": $request_length,"request_body":"$request_length","remote_addr":"$remote_addr","request_time": $upstream_response_time,"host":"$host","server_port":"80","clientIp":"$remote_addr","client_addr":"$remote_addr:$remote_port","request_uri":"$request_uri","time":"$time_iso8601","http_referer":"$http_referer","x_forwarded_for":"$http_x_forwarded_for","x_real_ip":"$http_x_real_ip","upstream_addr":"$upstream_addr","method":"$request_method","server_addr":"$server_addr","appName":"-$server_name","backendName":"-@kubernetes","source":"apisixAccess","trace_id":""}'
       access_log_format_escape: json
   
   ```
   access.log
   ```
   {"status": 200,"body_bytes_sent": 710,"scheme":"http","http_user_agent":"Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/99.0.4844.84 Safari/537.36","request_length": 569,"request_body":"569","remote_addr":"::1","request_time": 0.003,"host":"localhost","server_port":"80","clientIp":"::1","client_addr":"::1:55367","request_uri":"/headers","time":"2022-04-13T16:42:54+08:00","http_referer":"","x_forwarded_for":"","x_real_ip":"","upstream_addr":"127.0.0.1:1980","method":"GET","server_addr":"::1","appName":"-_","backendName":"-@kubernetes","source":"apisixAccess","uber_trace_id":""}
   
   ```
   
   Unfortunately, I also need several other parameters, refer to the partially custom variables using nginx-controller. These variables are not supported in APISIX. So ask if there is any way to get some of the above variable information.
   
   For example：
