一、获取全部cookie信息

  这个比较方便,直接在nginx.conf文件中添加$http_cookie

log_format main
    '[$time_local] - $remote_addr:$remote_port - $remote_user - $upstream_addr $upstream_status $upstream_response_time - '
    '"$request" $status $bytes_sent $request_time '
    '"$http_referer" - "$http_user_agent" '
    '"$http_cookie"';
# 增加一个 $http_cookie
Copy after login

  第二步,在server 中的access.log 后加上 main

access_log logs/item_access.log main;
  error_log logs/item_error.log ;
Copy after login

二、获取单个cookie的值

  有时候要是是觉得某个cookie很重要,需要单独取出来,免得去一堆麻烦

  首先,也是在nginx.conf文件中定义一个值,如 $my_cookie 

log_format main
    '[$time_local] - $remote_addr:$remote_port - $remote_user - $upstream_addr $upstream_status $upstream_response_time - '
    '"$request" $status $bytes_sent $request_time '
    '"$http_referer" - "$http_user_agent" '
    '"$my_cookie" "$http_cookie"';
# 这边定义了 $my_cookie 和 $http_cookie其实都能取到
# $my_cookie只能取到 value
Copy after login

  其次还是要改server 中的内容,

server {
  listen 80;
  server_name xxxx.****.com ;
  access_log logs/item_access.log main; # main 需要
  error_log logs/item_error.log ;
  set $my_cookie "";
  if ($http_cookie ~* "my_cookie=(.+?)(?=;|$)") {
  set $my_cookie $1;
  }
Copy after login

三、获取多个cookie的值

  如果觉得不止一个cookie的值重要,比如有两个cookie需要取出来,如何呢?重复第二步的动作

在nginx.conf 日志格式中增加也该 $my_cookie2 的变量

再在server 段中增加一个 set $my_cookie2那部分

log_format main
    '[$time_local] - $remote_addr:$remote_port - $remote_user - $upstream_addr $upstream_status $upstream_response_time - '
    '"$request" $status $bytes_sent $request_time '
    '"$http_referer" - "$http_user_agent" '
    '"$my_cookie" - "$my_cookie2" - "$http_cookie"';
  
server {
  listen 80;
  server_name xxxx.***.com ;
  access_log logs/item_access.log main; # main 需要
  error_log logs/item_error.log ;
  set $my_cookie "";
  if ($http_cookie ~* "my_cookie=(.+?)(?=;|$)") {
  set $my_cookie $1;
  }
  set $my_cookie2 "";
  if ($http_cookie ~* "my_cookie2=(.+?)(?=;|$)") {
  set $my_cookie2 $1;
  }
Copy after login

  我这边是实现了,但是命名不一样,大家自己尝试吧。

ps:nginx日志中添加cookie信息

1.在要添加的server中添加获取cookie的信息

server {
        listen     80;
        server_name   jxjymember.cdeledu.com;
        set $jxjymembercookie "";
        #此处如果想取全部cookie 可以写成 
        #if ( $http_cookie ~* "(.*)$" ){
        if ( $http_cookie ~* "jxjymembercookie=([a-za-z0-9_]*)" ){
          set $jxjymembercookie $1;
        }
        access_log   logs/jxjymember.cdeledu.com_access.log main;
        error_log   logs/error_jxjymember.cdeledu.com.log;
        location / {
             #
             proxy_pass       http://cdel_jxjy_member;
             proxy_redirect     off;
             proxy_set_header    host $host;
             proxy_set_header    x-real-ip $remote_addr;
             proxy_set_header    x-forwarded-for $proxy_add_x_forwarded_for;
             client_max_body_size  10m;
             client_body_buffer_size 512k;
             proxy_connect_timeout  300;
             proxy_send_timeout   300;
             proxy_read_timeout   300;
             proxy_buffer_size    64k;
             proxy_buffers      32 64k;
             proxy_busy_buffers_size 128k;
             proxy_temp_file_write_size 64k;
        }
    }
Copy after login

主要添加的地方都标红了,说明下:第一处的意思是:定义一个jxjymembercookie变量,变量的内容从http的cookie去取,取的规则是匹配后面的正则jxjymembercookie=([a-za-z0-9_]*),其实http_cookie这个里面的值是一个一个cookie的值,中间以“;”分隔。

2.在log_format main中添加上要添加的变量名。

log_format main   '$proxy_add_x_forwarded_for - $remote_user [$time_local] '
             '"$request" $status $bytes_sent '
             '"$http_referer" "$http_user_agent" $jxjymembercookie ';
Copy after login
