如何在Nginx的access日志中记录POST、Header和Cookie中的参数信息？

http {

    include       mime.types;

    default_type  application/octet-stream;



    log_format  main  '$remote_addr - $remote_user $server_name [$time_local] "$request" '

                      '$status $body_bytes_sent "$request_body" "$http_referer" '

                      '"$http_user_agent" "$http_x_forwarded_for" "clickpid=$cookie_clickpid" "clickaid=$cookie_clickaid"';



    access_log  logs/access.log  main;



    sendfile        on;

    #tcp_nopush     on;



    #keepalive_timeout  0;

    keepalive_timeout  65;



    #gzip  on;



    server {

        listen       8080;

        server_name  localhost;



        #charset koi8-r;



        access_log  logs/host.access.log  main;



        location ~ \.php$ {

　　　　　　　#这里会记录post数据

            access_log logs/post.log main;

            proxy_set_header Host $http_host;

            proxy_pass   http://127.0.0.1;

        }



        location / {

　　　　　　　#这里不会记录post数据　

            root   html;

            index  index.html index.htm;

        }
