• 空格：默认匹配，普通匹配 ```shell location / { root /home; }

- =：精确匹配
```shell
location = /imooc/img/face1.png {
    root /home;
}

• ~*：匹配正则表达式，不区分大小写 ```shell

  符合图片的显示

  location ~* .(GIF|jpg|png|jpeg) { root /home; }

- ~：匹配正则表达式，区分大小写
```shell
#GIF必须大写才能匹配到
location ~ .(GIF|jpg|png|jpeg) {
    root /home;
}

• ^~：以某个字符路径开头 ```shell location ^~ /imooc/img { root /home; }

```
