调试用的

log_format json  '{'
        '"time_local":"$time_local",'
        '"time_iso8601":"$time_iso8601",'
        '"host":"$host",'
        '"remote_addr":"$remote_addr",'
        '"http_x_forwarded_for":"$http_x_forwarded_for",'
        # $remote_user等同于用户名，由ngx_http_auth_basic_module认证
        '"remote_user":"$remote_user",'
        # 客户端port
        '"remote_port":"$remote_port",'
        '"request":"$request",'
        # 含有参数的完整的初始URI
        '"request_uri":"$request_uri",'
        # $query_string与$args一样
        '"args":"$args",'
        '"query_string":"$query_string",'
        '"status":"$status",'
        # 协议，通常是“GET”或“POST”
        '"request_method":"$request_method",'
        '"server_protocol":"$server_protocol",'
        '"request_body":"$request_body",'
        # 当前请求的文件的路径名，由root或alias和URI request组合而成
        '"request_filename":"$request_filename",'
        '"body_bytes_sent":"$body_bytes_sent",'
        '"http_referer":"$http_referer",'
        '"http_user_agent":"$http_user_agent",'
        '"upstream_addr":"$upstream_addr",'
        '"upstream_response_time":"$upstream_response_time",'
        '"upstream_status":"$upstream_status",'
        '"request_time":"$request_time",'
        '"cookie_uid":"$cookie_uid"'
        '}';

loghao 记录下来以后用

    log_format  loghao  '[$time_local] - $remote_user $http_x_forwarded_for - $host$request_uri $status $request_method $server_protocol $body_bytes_sent '
        '"$http_referer" "$request_body" "$http_user_agent" "$request_filename" '
        '"$upstream_addr" "$upstream_response_time" "$upstream_status" $request_time';
