nginx正则匹配

需求：由于运营商缓存，需要域名后加上时间以便绕过缓存，例：www.name.com/yyyy-mm-dd/ 和www.name.com返回同样的数据，这时候就需要nginx的正则匹配

写法

location ~ ^/\d+\-\d+\-\d+/(.*)$ {
      alias /etc/nginx/html/$1;
}

• 重点是（）和$1,如果不写，会报404/403
• nginx文档：

If alias is used inside a location defined with a regular expression then such regular expression should contain captures and alias should refer to these captures (0.7.40), for example:

location ~ ^/users/(.+\.(?:gif|jpe?g|png))$ {
    alias /data/w3/images/$1;
}
