url地址重写
rewrite模块：rewrite指令
sysntax : rewrite regex replacement [flag];
Default: -
Context: server,location,if
功能：
将regex指定的URL替换成replacement这个新的url可以使用正则表达式
当replacement以http://或者https://或$schema开头，则直接返回302重定向
替换后的url根据flag指定的方式进行处理
last:用replacement这个url进行新的location匹配
break:break指令是停止当前脚本指令的执行，等价于独立的break指令
redirect：返回302重定向（临时重定向）
permanent：返回301重定向（永久重定向）
