Daily Blink Page Layout has changed - IndexError: list index out of range

[ptrstn]

The Layout and URL of the Free Daily Page has changed.

New URL: https://www.blinkist.com/en/content/daily

The locator attribute values for BeautifulSoup have to be updated accordingly. Previous values are no longer valid and cause an IndexError:

    def _create_blink_info(response_text):
        soup = BeautifulSoup(response_text, "html.parser")
>       daily_book_href = soup.find_all("a", {"class": "daily-book__cta"})[0]["href"]
E       IndexError: list index out of range

confirmed, having this also since... 22.05.2022, because last folder i have in my library is:
'2022-05-21 - Finde den Weg zu deiner inneren Mitte'/

Jap same here. How to fix this?

[NicoWeio]

I was able to retrieve audio and text content for the free daily by calling Blinkist's API the way the frontend does. I prefer this over BeautifulSoup because it's more direct and the new DOM lacks descriptive classes/IDs. However, I haven't integrated my approach with this codebase, and I'm not sure if it works the same for arbitrary books on Blinkist Premium. If anyone's interested, I'll post my code tomorrow. :)

Perfect, let me please know!

⚠️ Update: I've created a repo with updated code here

Again, I haven't tried other values for User-Agent yet, and I can't check whether this approach will work for Premium content.

@NicoWeio does your code work straight out of the box, or does this to be replaced with the core.py ?

[WrayOfSunshine]

Would this approach work on a Windows machine?

See my earlier comment:

Assuming you have cloudscraper installed, my script works out of the box, and it should download the audio just fine. However, it does not generate a text or cover image file, does not set the audio's metadata, and does not precisely follow dailyblink's naming conventions.

[NicoWeio]

Would this approach work on a Windows machine?

If dailyblink worked on Windows before, yes. Both my approach using Blinkist's API and the current approach using BeautifulSoup.

@ptrstn Is there a fix/update coming? you said until Sunday and then you removed your answer.

@ptrstn Is there a fix/update coming? you said until Sunday and then you removed your answer.

This change requires some refactoring and a little bit more time than initially expected. I'll see what I can do. Can't guarantee you when though, since I've got other things in life to take care of first.

Executing this code on google colab I am getting 403 forbidden error on line 70 when calling get_chapters after troubleshooting I found that response.raise_for_status() gives that error as it can't access the url which gives this error. how can I resolve this?
@NicoWeio

[NicoWeio]

@rajeshbhavikatti I just published my code here, so we can keep this issue clean from further discussions.
Notice the double slash in the URL? That might be the cause, although it didn't cause issues for me. Maybe because of a different requests version? Anyway, I fixed the double slashes in my code. Plus, I've added CI to my repo, and it works just fine there, too.

Hi Peter @ptrstn , do you have some updates on this?

Hi Peter @ptrstn , do you have some updates on this?

I'll be able to work on it starting beginning of October, since I'm still busy with private issues

Hi, I have made some updates based on this repo feel free to reach out to me on any changes or update check out my notebook here

[Erik262]

@rajeshbhavikatti nice work, but you don't catch the mp3 files.

[rajeshbhavikatti]

@Erik262 yes, as the notion API doesn't support it yet
