[root@nginx nginx-1.24.0]# nginx- location案例
location区段，通过指定模式来与客户端请求的URL相匹配
功能：
允许根据用户请求的URL来匹配定义的各个location，匹配时，此请求将被相应的location配置块中的配置所处理，例如做访问控制等功能
语法：
location [修饰符] pattern {......}
修饰符
= 精确匹配
~ 正则表达式模式匹配，区分大小写
~* 正则表达式模式匹配，不区分大小写
^~ 前缀匹配，类似于无修饰符的行为，也是以指定模块开始，不同的是，如果模式匹配，那么就停止搜索其他模式了，不支持正则表达式
@ 定义命名location区段，这些区段客户端不能访问，只可以由内部产生的请求来访问，如try_files或者error_page等
