I'm switching a Laravel Website from Apache (htaccess) to NGinx. I have built an Image Serving that produces a uri with the appropriate parameters for resizing ex : pics/images/max24h/music_video_red_icon.png.
I Apache does not find the file it would redirect it to a route image/images/max24h/music_video_red_icon.png where an Action in laravel creates and returns the image. In .htaccess it works with this code :

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^pics(.*).(jpe?g|png|gif|ico|bmp)$ /image$1.$2 [R=307,L]

Now in NGinx conf, How do I redirect it properly? I tried a lot of suggestions like :

# Redirect pics file not found to php laravel route to create the image

location @img_proxy {

    rewrite ^/pics(.*).(jpe?g|png|gif|ico|bmp)$ /image$1.$2;

}



location / {

    try_files $uri $uri/ /index.php?$query_string;

}

It does not work at all, the server works if I remove those lines. I'm using Mac High Sierra 10.13.6 . Could it be some config conflict? Here is the full nginx.conf :

The main difference between the function of the .htaccess file and your rewrite statement is that Apache will perform an external redirect using a 307 response, while Nginx performs an internal redirect instead. See this document for details.

To force Nginx to perform an external redirect, append the permanent or redirect flag to the rewrite statement, which generates a 301 or 302 response respectively.

For example:

location @img_proxy {

    rewrite ^/pics(.*).(jpe?g|png|gif|ico|bmp)$ /image$1.$2 redirect;

}

The difference between a 302 and a 307 response, is that the latter will redirect a POST request method without changing it to a GET.

If you need to redirect POST requests, you will need to capture the relevant parts of the URI with a regular expression location or if block and use a return 307 instead.

For example:

location @img_proxy {

    if ($uri ~ ^/pics(.*).(jpe?g|png|gif|ico|bmp)$) {

        return 307 /image$1.$2$is_args$args;

    }

}

See this caution on the use of if.
