假设当前nginx服务器IP为 192.168.1.1

直接访问，可以进到前台；

现在请求后台 http://192.168.1.1/aaa/type/list

斜杠其实就是分隔符，会匹配 / 后面的内容。并且根据proxy_pass中是否存在斜杠，proxy_pass有斜杠就匹配的内容去除location中有的；如果没有斜杠就会把location中匹配的内容带过来。

例如这个：

location /aaa {
    proxy_pass  http://192.168.2.1:8080;
}

http://192.168.1.1/aaa/type/list 代理后的则为 http://192.168.2.1:8080/aaa/type/list

location /aaa/ {
    proxy_pass  http://192.168.2.1:8080;
}

http://192.168.1.1/aaa/type/list 代理后的则为 http://192.168.2.1:8080/aaa/type/list

location /aaa {
    proxy_pass  http://192.168.2.1:8080/;
}

http://192.168.1.1/aaa/type/list 代理后的则为 http://192.168.2.1:8080/type/list

location /aaa/ {
    proxy_pass  http://192.168.2.1:8080/;
}

http://192.168.1.1/aaa/type/list 代理后的则为 http://192.168.2.1:8080/type/list

反向代理的时候，如果头部包含 下划线 例如：access_token 需要设置一下；需放在http {} 下

Nginx静态资源部署问题

alias和root的区别

根路径和虚拟路径

alias 匹配的是指定的目录

root 匹配的是上级目录

例如 目录 /b/a/1.txt

配置root形式想要访问1.txt

location /a {
	root /b;
}

访问 http://localhost/a/1.txt 是可以访问到的，因为root形式是：root配置的路径 + location路径 拼接成的；

配置alias的形式访问1.txt

location /xx/ {
   alias /a/b/;  # b后面的斜线不能去掉
}

访问：http://localhost/xx/1.txt 即可访问
