Wrong url or unsupported link ... {0}

Error message

Wrong url or unsupported link ... {0}

What it means

Terminal else-branch of longzhu_download: the URL's host matched none of the supported Longzhu subdomains (star.longzhu.com, y.longzhu.com, replay.longzhu.com). you-get raises ValueError with the offending URL so the caller knows the link is routable to no extractor branch.

Solutions

Use the exact supported forms: http://star.longzhu.com/<domain>, http://y.longzhu.com/<domain>, or http://replay.longzhu.com/<videoId>
Open the page in a browser and copy the URL from the address bar once the video/replay is playing
If a legitimate new subdomain exists, add an elif branch for it before the else and raise

Example fix

# before
you_get 'http://www.longzhu.com/room/12345'  # -> Wrong url or unsupported link

# after
you_get 'http://star.longzhu.com/12345'    # live room branch
you_get 'http://replay.longzhu.com/182308'  # replay branch

Defensive patterns

Strategy: validation

Validate before calling

from urllib.parse import urlparse

def is_supported_longzhu(url):
    host = urlparse(url).netloc
    return host in ('star.longzhu.com', 'y.longzhu.com', 'replay.longzhu.com')

Try / catch

try:
    longzhu_download(url, ...)
except ValueError as e:
    if 'unsupported link' in str(e):
        print('use a star./y./replay.longzhu.com URL')
    else:
        raise

Prevention

Validate the URL host against the three supported Longzhu subdomains before calling
Copy the URL only from the address bar while the room/replay is open
Automate routing with a host->extractor map instead of substring guesses

When it happens

Trigger: Passing any Longzhu URL whose web_domain is not star./y./replay., e.g. 'http://www.longzhu.com/...', 'http://longzhu.com/...', or a malformed URL where url.split('/')[2] yields an unexpected host string.

Common situations: Copy-pasting the site root or a channel-listing page instead of a room/replay page; site introducing a new subdomain (e.g. mobile m.longzhu.com links) the extractor never learned; trailing slashes or query strings producing an unexpected domain token.
