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
[root@www extra]# cat www.confserver {listen 80;server_name www.etiantian.org etiantian.org;root html/www;location / {return 401;}location = / {return 402;}location /documents/ {return 403;}location ^~ /images/ {return 404;}location ~* \.(gif|jpg|jpeg)$ {return 500;}access_log logs/access_www.log main ;}

测试结果截图
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。
