Extensions work for specific subscription？

[Nikkiiw]

Hi!
Firstly thx for all the work.
Can extensions work for specific subscription？
Like ImageProxy, some pic of subscription do not need proxy , but some other do.
Thank you for reply.

yes. It depends on the extension.

It depends on the used proxy. See: https://github.com/FreshRSS/Extensions/tree/master/xExtension-ImageProxy
If WSRV.NL is used I cannot find a fitting configuration

@math-GH Thx！
But ImageProxy is just a exemple.
Does FreshRSS has a switch or something can let user choose which extension work for a specific subscription?
Like subscription A use ImageProxy,
subscription B use FeedTitleBuilder

Or some config file?

There is no such function at the moment, but extensions can decide which feed to apply to and could expose some settings for that

@Alkarex thx！ I will do some research

[Nikkiiw]

@Alkarex I'm really sorry I do some research but can not find out how to do it.
Can you show some example?
appreciate that!

scheme_default (default: auto): which scheme to use for resources that do not include one; if set to -, those will not be proxied; if set along scheme_include, the scheme included in the URL will either be auto-matically derived from your current connection or the one explicitly specified

This is from Image Proxy.Use this function to decide? Am I correct?

You would have to patch the extension for your needs.

In the following code, $entry has access to the feed information:

Extensions/xExtension-ImageProxy/extension.php

Lines 147 to 152 in 64b5ac4

	public static function setImageProxyHook(FreshRSS_Entry $entry): FreshRSS_Entry {
	$entry->_content(
	self::swapUris($entry->content())
	);
	return $entry;

return $entry;

I was looking at this as I would like to implement a whitelist for domains which break wsrv.nl (usually because they used their own image proxy). Is it correct to think (roughly) that checking $entry->_url against a whitelist (skipping swapUris to return the vanilla entry if we have a match) would be the most parsimonious approach?

That would skip a lot of processing I suppose, but intuitively I'd expect in e.g. getProxyImageUri().
