location的匹配规则

  1. 语法规则： location [=|~|~*|^~] /uri/ { … }
  2. =      #用于标准uri前，需要请求字串与uri精确匹配，如果匹配成功就停止
  3. ~      #用于标准uri前，表示包含正则表达式并且区分大小写
  4. ~*     #用于标准uri前，表示包含正则表达式并且不区分大写
  5. !~     #用于标准uri前，表示包含正则表达式并且区分大小写不匹配
  6. !~* 　 #用于标准uri前，表示包含正则表达式并且不区分大小写不匹配
  7. ^~    #用于标准uri前，表示包含正则表达式并且匹配以什么开头
  8. $     #用于标准uri前，表示包含正则表达式并且匹配以什么结尾
  9. \     #用于标准uri前，表示包含正则表达式并且转义字符。可以转. * ?等
  10. *     #用于标准uri前，表示包含正则表达式并且代表任意长度的任意字符
  11. 匹配优先级：=, ^~, ~/~*，/
  12. location优先级：(location =) > (location 完整路径) > (location ^~ 路径) > (location ~,~* 正则顺序) > (location 部分起始路径) > (/)
