Feature request + Bug: DeepL & Google Translate free alternative / Fanyi Youdao validation issues

[jiangaq]

Thank you.

[Fevol]

Thank you for the feature request!

Officially speaking, there is no fully free choice for either DeepL or Google Translate, unless you've signed up for their API.

The plugin does include LingvaTranslate, which is a freely accessible Google Translate scraper (i.e. does not require sign-up), it should work out of the box -- though you may have to switch hosts to get the one that works best for you (or host the service yourself using Docker/Vercel).

As for DeepL, I can't immediately find any scrapers that work reliably and could also be added to the plugin easily. If the LingvaTranslate service doesn't work for you, I'm afraid the only other option would be to embed the websites as iframes, though I haven't tried that method myself.

Thank you for your explain.

However, I have youdao api, but it doesn't work, showing "Translation service is not validated".

When testing in setting, it shows "Validation failed: undefined".

Could you please check?

[Fevol]

Many thanks for pointing that out, it seems that the error code was not being shown properly. Something else does seem to be wrong with the validation request.

If you don't mind, could you download the below zip, and unpack it in .obsidian/plugins/translate? It contains an updated script that fixes the error code issue.

Then validate the service again and see what error code it gives, that would be immensely helpful for fixing the issue with Youdao!

Tried, it shows "Validation failed: 202" now, what does that mean?

[Fevol]

According to Youdao's API docs, it looks like the signature verification is failing due to an encoding problem. I'm not sure why that is happening, but I'll try to fix the issue ASAP.

[Fevol]

Looks like I made a few tiny mistakes with the signature procedure, could you check if it works now?

New attempt:

[jiangaq]

Now returned ""Validation failed:0"

[Fevol]

Alright, after double-checking, status code "0" should mean that the request was correctly sent and retrieved, or in other words: all functions work properly.

Had to fix one last issue, but with this, you should be able to validate the service and translate text now.

Fixed version: https://github.com/Fevol/obsidian-translate/files/10359449/translate.zip

I'm really grateful for all your help with debugging this issue!

[Fevol]

Sorry, I've uploaded the wrong version, this is the actual fix:

[jiangaq]

It works now, thank you so much!

[Fevol]

Incredibly glad to hear that! If you find any issues related to Youdao (or anything else), do let me know.
I'll try pushing an official fix later today, which will hopefully also improve the error messaging.

Again, thank you for helping me debug this!

[Fevol]

I'm going to mark this as closed for now.

You can absolutely re-open this issue in case you find another bug with Fanyi Youdao!

If you (or anybody else) would like to suggest a DeepL scraper alternative for the plugin, please open up a new feature request issue.
