Serving arbitratry file by path

[nicklayb]

Hi, I'm trying to serve a file from a remote arbitrary server but I cannot make it work. Example, I'm trying to process the following file:

https://cf.geekdo-images.com/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg

I tried the following without success:

• http://localhost/https://cf.geekdo-images.com/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg
• http://localhost/https%3A%2F%2Fcf.geekdo-images.com%2FY4_BmMKtbr7P5tOaRYtJSQ__original%2Fimg%2FLfOrZWAdcVrvr5MqJ8McEG4eYuw%3D%2F0x0%2Ffilters%3Aformat%28jpeg%29%2Fpic5934281.jpg (url encoded)
• https://localhost/aHR0cHM6Ly9jZi5nZWVrZG8taW1hZ2VzLmNvbS9ZNF9CbU1LdGJyN1A1dE9hUll0SlNRX19vcmlnaW5hbC9pbWcvTGZPclpXQWRjVnJ2cjVNcUo4TWNFRzRlWXV3PS8weDAvZmlsdGVyczpmb3JtYXQoanBlZykvcGljNTkzNDI4MS5qcGc= (Base 64 encoded, the imgproxy docs says it should support encoded 64 url)

Hi @nicklayb

This project is simply a basic setup for using Nginx as a cache server for imgproxy with some simple rewrite rules so that many people can set up a simple image processing server themselves. Regarding the issue you are raising, I think this question should be discussed in the official repository of imgproxy or thumbor (the server from which you want to access images).

Best regards

[nicklayb]

Not really, they do support it, it's just that your nginx prevents support for it.

I don't nginx much but I managed to do it by replacing

-    default     'local://'
+    default     'https:/'

And I provide the url without the https scheme

(A / is appended automatically, not sure why)

And it works, calling localhost/this.is.the.picture.path.png

Hi @nicklayb

Thank you for your feedback. If your adjustments work, then I believe you have configured Nginx correctly for your requirements.

My project is just a basic setup for a general image processing server, and you will need to make further adjustments to suit your specific needs.

Best regards.

By the way, in the imgproxy.conf file, under the $origin_server settings, I've already explained how to add configs for image hosts (Line 103).

docker-imgproxy/imgproxy.conf

Lines 95 to 109 in 218bc6d

	## **`$origin_server`**
	## Define origin base URL from the request.
	## This setup assumes that an origin server starts with an `@` symbol (such as `@nasa`, `@pinterest`, etc.).
	## You can also add your own origin servers using [regular expressions](https://www.nginx.com/blog/regular-expression-tester-nginx/).
	map $uri $origin_server
	{
	default 'local://';
	# Put your rewrite rules for origin servers from here.
	#> E.g.
	~^/@mybucket/ 's3://my-bucket';
	~^/@myhost/ 'http://myhost.com';
	~^/@nasa/ 'https://mars.nasa.gov/system/downloadable_items';
	~^/@pinterest/ 'https://i.pinimg.com/originals';
	}

Why don't you try adding a line for the host you want to access in the format I recommended?

map $uri $origin_server
{
    default         'local://';

    # Put your rewrite rules for origin servers from here.
    ~^/@sample/     'https://cf.geekdo-images.com';
}

After adding it, you can simply access the image at the following link:

http://localhost/@sample/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg

And even combine it with pre-built filters, such as:
http://localhost/@sample/_thumb/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg

http://localhost/@sample/_small/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg

http://localhost/@sample/_w640/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg

http://localhost/@sample/_blurry/Y4_BmMKtbr7P5tOaRYtJSQ__original/img/LfOrZWAdcVrvr5MqJ8McEG4eYuw=/0x0/filters:format(jpeg)/pic5934281.jpg

I put a lot of effort into this project, and I hope it will be truly useful for anyone interested in learning from the available configurations.

If it doesn't work for you, I'm really sorry, I would encourage you to find another configuration that works better for you rather than suggesting using this project.

Best regards.

It just works!

But again, your example doesn't use the raw url, only the path if I see correctly. What I was trying to achieve was the full url (scheme, domain and path)

But that's ok, my solution satisfies me enough
