nginx 日志打印post请求参数

在日志格式后面加上 $request_body 配置信息

 log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for" $request_body';

 access_log  logs/access.log  main;
 log_format
