External Storage

[Barry]

Hey gang.

I have setup an external SFTP. When I upload the image, I see that the file is indeed uploaded to the SFTP, however when attempting to access it via browser, I get a 404.

URL: https://clubwallpapers.com
External Storage URL: https://i.clubwallpapers.com the appropriate dns entries have been made.

Here is an example.
https://clubwallpapers.com/image/VjbkL is the main image. Actual image address is
https://i.clubwallpapers.com/AnimeManga4.md.jpg

Any idea what I did wrong here?

Chevereto tries to check if the image is there (your server request file http header from the external storage server). If that fails you will get that 404 thing.

So there needs to be a webserver on the sftp server? No big deal, but just need to be sure

Of course you need a webserver in the external storage server, otherwise the images can't be served via HTTP.

You should debug the output here:

app/routes/route.index.php

        // Test remote image
        if($image['file_resource']['type'] == 'url') {
            $url = preg_replace('/^https:/i', 'http:', $image['file_resource']['chain']['image']);
            $headers = G\getUrlHeaders($url, [CURLOPT_REFERER => G\get_current_url()]); // Add referrer for some CDN restrictions
            $error_tpl = "Can't fetch file header from external storage server: %url (%e)";
            if($headers['http_code'] == 500) { // Internal (curl) error
                $error_e = $headers['error'];
            } else if($headers['http_code'] !== 200) {
                $error_e = $headers['http_code'];
            }
            if($error_e) {
                error_log(strtr($error_tpl, ['%url' => $url, '%e' => $error_e]));
                if($headers['http_code'] !== 200) {
                    return $handler->issue404();
                }
            }
        }

A minimal NGINX server config works fine for that.

Without SSL:

server {
  listen 80;
  server_name your.domain.name;
  access_log /path/to/your/access.log;
  error_log /path/to/your/error.log;
  location / {
    expires 90d;
    root /path/to/your/root/;
  }
}

With SSL:

server {
  listen 80;
  listen 443 ssl http2;
  listen [::]:443 ssl http2;
  ssl_certificate /path/to/your/certificate.cer;
  ssl_certificate_key /path/to/your/certificate.key;
  ssl_session_cache shared:SSL:20m;
  ssl_session_timeout 60m;
  ssl_prefer_server_ciphers on;
  ssl_ciphers ECDH+AESGCM:ECDH+AES256:ECDH+AES128:DH+3DES:!ADH:!AECDH:!MD5;
  ssl_dhparam /path/to/your/dhparam.pem;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  add_header Strict-Transport-Security "max-age=31536000" always;
  server_name your.domain.name;
  access_log /path/to/your/access.log;
  error_log /path/to/your/error.log;
  location / {
    expires 90d;
    root /path/to/your/root/;
  }
}

                }
            }
        }

Thanks _ thought maybe the image was "pulled" via SFTP and presented from the parent server....

No, it just fetch the image headers. Anyway, I will remove that for the next version.
