log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for" '
'"$http_host" "$request_time" "$upstream_response_time" $http_device $http_appversion $upstream_addr '
'$http_openudid $http_code $http_networkType "$http_deviceModel" "$http_osVersion"';
解析格式为
