nginx location规则

To summarize, the order in which directives are checked is as follows:

1，Directives with the “=” prefix that match the query exactly. If found, searching stops.

2，All remaining directives with conventional strings. If this match used the “^~” prefix, searching stops.

3，Regular expressions, in the order they are defined in the configuration file.

4，If #3 yielded a match, that result is used. Otherwise, the match from #2 is used.

个人总结：

1，普通匹配的表达式不能重复，正则匹配的表达式不能重复（不同的修饰符可以重复，比如~和~*）

2，正则匹配：要有~（大小写敏感）获取~*（大小写不敏感）

普通匹配：^~或=或空

3，最大前缀匹配，uri要尽量匹配更多的前缀

4，普通匹配没有编辑的顺序，正则有

5，正则location让位于=和^~，覆盖其他的普通location
