Question

Anyone tell me how to rewrite URL in Nginx

to

https://dl.expamledomain.com/dwn/524/mmmnGreUwmpRTGl7RO9NtGLhgQZrQ1IW/file.zip

second our download.php file in the root public_html folder.

I have used this rule on .htaccess

RewriteEngine On

RewriteRule ^dl/(\w+)/(\w+)/(.*)/?$ download.php?pt=$1&tk=$2&flen=$3 [L,QSA,NC]

its working fine but I try many on Nginx rule like this

I try this code in Nginx but not working

    http{

       server {
          listen       80;
          server_name  *.oursitename.com;

   location / {
    rewrite ^(?i)/dl/(\w+)/(\w+)/(.*)/?$ /download.php?pt=$1&tk=$2&flen=$3 last;
 }

  location = /download.php {
    # Your fastcgi_pass configuration
}
    }

its show me this error

" open() "/home/username/public_html/dl/515/25xfkUNYOGvvOt0z7ko9YkpHCWZrlRfX/file72.exe" failed (2: No such file or directory),"

our file location like this

1.Home
    1.Username
     1.public_html
       1.downloadfolder
       2.download.php
       3.index.php
       4.htaccess

NGINX rewrite rules always use absolute URI Paths, so in order to rewrite your second URL into the first one (which is what the provided Apache2 rule does), you just need to add a couple of /:

location / {
    rewrite ^(?i)/dl/(\w+)/(\w+)/(.*)/?$ /download.php?pt=$1&tk=$2&flen=$3 last;
}
location = /download.php {
    # Your fastcgi_pass configuration
}

The NC flag is translated into the PCRE mode modifier (?i) (cf. this question), while the QSA flag is the default NGINX behaviour.

Remark: Under Apache2 it is also better to put your rewrite rules in the server config, instead of .htaccess files and disable them altogether: you gain in performance and they will not be published on the Web if you make a configuration mistake.
