Location规则

语法规则： location [=|~|~*|^~] /url/ {… }

符号 含义
= = 开头表示精确匹配
^~ ^~开头表示uri以某个常规字符串开头，
理解为匹配url路径即可。
~ ~ 开头表示区分大小写的正则匹配
~* ~* 开头表示不区分大小写的正则匹配
!~和!~* !~和!~*分别为区分大小写不匹配及
不区分大小写不匹配的正则
/ 用户所使用的代理（一般为浏览器）

精确匹配

=

普通匹配

无符号
^~

正则匹配

~
~
!-
!-

  23.                 echo '= /jrf';
  24.         }
  27. }
  1. curl http://yxj.mxs223.com:8080/jrf/index.html
  3. curl http://yxj.mxs223.com:8080/jrf/cms
  5. curl http://yxj.mxs223.com:8080/jrf/cms/
  7. curl http://yxj.mxs223.com:8080/jrf/cms/index.html

正则匹配优先级


1、location 配合先后顺序与配置文件location 先后顺序无关
2、如果都是普通匹配，最长的会被命中
3、普通匹配会被正则所覆盖
3、^~ 普通匹配 不会被正则所覆盖
4、=精准匹配直接命中
