nginx正则表达式求助

Question

我想用nginx的rewrite功能，当有人请求

https://www.xxx.com/upload/logo/5db1da5a1c9ee295f8e49f8fc03f51bf/

自动在尾部加上 raw.jpg

https://www.xxx.com/upload/logo/5db1da5a1c9ee295f8e49f8fc03f51bf/raw.jpg

怎么写规则最好呢？最好能/upload/logo/忽略这些目录

Answer 1

打游戏的时候，脑子突然反应过来，我吧raw.jpg加到默认文档里不就行了，何必写什么正则！哈哈

server {
    ...
    index index.html index.php raw.jpg;
    ...
}

Answer 2

location / {
    try_files raw.jpg @fallback;
}

Answer 3

这样写可以吧

location / {
    # rewrite /(upload/logo/[0-9,a-f]+)/$ $1/1raw.jpg;
    rewrite /(\w+/\w+/[0-9,a-f]+)/$ $1/1raw.jpg;
}
