Nginx 重写 - 从 URL 中删除 static 资产的路径段？

Question

I have the following URL:

https://example.com/<template>/v1/a/b

I wanted to rewrite it to https://example.com/<template>/index.php?v=v1&p1=a&p2=b , and managed to do so using the regex below.

I also have the following static URLs being called from index.php :

https://example.com/<template>/v1/a/b/assets/images/intro.png

How can I redirect all assets to their proper location? which is:

https://example.com/<template>/assets/...

Here is my setup so far:

server {
    root /var/www/html;
    index index.html index.php;
    server_name _;

    location / {
      try_files $uri $uri/ @rewrites;
    }

    location @rewrites {
      rewrite ^(.*)/(.*)/(.*)/(.*)/?$ $1/index.php?a=$2&b=$3 last;
    }

    location ~ \.php$ {
      fastcgi_pass unix:/run/php/php8.0-fpm.sock;
    }
}

Answer 1

If the URIs pointing to assets contain the literal word /assets/ , you just need a regular expression that matches that part of the URI.

For example:

location ~ ^(/[^/]+)(/.*)?(/assets/.*)$ {
    try_files $1$3 =404;
}

The regular expression captures the first word (using the character class [^/] to match anything which is not a / character), and everything from the word assets to the end of the URI, both of which are subsequently used in the try_files statement.
