Are you writing extractors or just using youtube-dl as a CLI program?

[deangelo200]

Writing an extractor
` with youtube_dl.YoutubeDL(ydl_opts) as ydl:
info_dict = ydl.extract_info(url, download=False)
video_id = info_dict.get("id", None)
video_title = info_dict.get('title', None)
video_thumb = info_dict.get('thumbnail',None)
context = {
'form': form,
'title':video_title,
'id': video_id,
'thumbnails':video_thumb

                }`

Well, at this level _is_valid_url is not available. Need other approaches. What's your scenario?

[deangelo200]

I want to add a feature to my website to let persons download songs but if the person entered an invalid url i want to run some functions

[yan12125]

I guess I've got you. Just catch ExtractorError and analyze it

[deangelo200]

How to do this ? Can you give me a short example please

[yan12125]

Like this. Do whatever you want to e.

from youtube_dl.utils import ExtractorError

try:
    info_dict = ydl.extract_info(url, download=False)
except ExtractorError as e:
    print(e)

Hey am getting this error instead of getting this error i want to send the user to a page

How about using Regular Expressions to check? Pretty much the standard way to validate form input.

[deangelo200]

I was thinking the same thing but i want to send the users to an error page if their is an error in the url.

[yan12125]

Oops I forgot DownloadError wraps ExtractorError. Replace ExtractorError in the previous code with DownloadError

Are you familiar with Django

[deangelo200]
