nginx日志记录请求包

使用log_format指令来更改日志格式,该指令只能放在http{}段

log_format 日志名 '日志内容';

$request_body是nginx的内置变量,可以记录post的数据
$time_local 格式化的时间
$request 请求地址
$status 响应码
$body_bytes_sent 传送页面的字节数
$http_referer 来源地址
$http_user_agent 客户端UA
$document_root 当前文件的目录绝对地址,比如:/var/www/html
$fastcgi_script_name 当前url的绝对地址,比如:/info.php
$request_filename 当前请求文件的绝对物理地址,基于root和alias指令,比如:/var/www/html/info.php
$http_cookie cookie信息,这个也很重要,如果在cookie中带上了用户的标识,比较方便调试

# 在nginx http{} 里面写下以下内容
 log_format request_log escape=json '{"DATE":"$time_local","URL":"$request","STATUS":"$status","REFERER":"$http_referer","AGENT":"$http_user_agent","BODY":"$request_body","COOKIE":"$http_cookie"}';

# 在server中使用
access_log  /www/wwwlogs/xxx.com.log request_log;



# 日志中将会记录以下格式的内容
