nginx-location使用

location语法



location使用的语法例子为：
location [=|~|~*|^~] uri{

对location语法列表说明。
|1ocation | [=|~|~*|^~] |uri |{..}.
|指令 |匹配标识。 |匹配的网站网址。|匹配URI后要执行的配置段。


上述语法中的URI部分是关键，这个URI可以是普通的字符串地址路径或者是正则表达式，当匹配成功则执行后面大括号里面的相关指令。正则表达式的前面还可以有~或~*等特殊的字符。

这两种特殊字符~或~*匹配的区别为：
“ ~ ” 用于区分天小写(大小写敏感)的匹配；~/images{}
“ ~* ” 用于不区分大小写的匹配。还可以用逻辑操作符！对上面的匹配取反，即 ！~ 和！~* 。
“ ^~ ” 作用是在常规的字符串匹配检查之后，不做正则表达式的检查，即如果最明确的那个字符

实现配置

小结





不用URI及特殊字符组合匹配顺序    匹配说明


第一名：“location  = / {”    精确匹配/


第二名：“location  ^~ /images/ {”     匹配常规字符串，不做正则匹配检查, 优先匹配路径


第三名：“location  ~* \.(gif|jpg|jpeg)$ {”     正则匹配


第四名：“location  /documents/ {”     匹配常规字符串，如果有正则则优先匹配正则。


第五名：“location  / {”     所有location都不能匹配后的默认匹配。
