Share not found or canceled: %s

Error message

Share not found or canceled: %s

What it means

Raised as AssertionError in baidu_pan_download (src/you_get/extractors/baidu.py:195). After fetching the share page, baidu_pan_parse fails to extract a sign token (sign is None) and the page does not contain the 'access-code' marker for password-protected shares, so the share is treated as deleted, canceled, or never existed.

Solutions

  1. Verify the share URL still opens in a browser; if Baidu says the file was canceled/deleted, obtain a fresh share link.
  2. If the share needs a password, make sure the page is recognized as protected (the 'access-code' marker must appear) and pass the correct password so baidu_pan_protected_share runs.
  3. If the URL is valid in a browser, the site markup likely changed — update the regexes in baidu_pan_parse or upgrade you-get to a newer release.

Example fix

# before
baidu_pan_download('http://pan.baidu.com/share/link?shareid=123&uk=456')  # dead link

# after (verify share exists, then fetch)
# open the URL in a browser first; if canceled, get a new share link
baidu_pan_download(new_valid_share_url)
Defensive patterns

Strategy: try-catch

Validate before calling

import re

def baidu_share_alive(html):
    # same signal the extractor uses: a parseable sign or an access-code marker
    has_sign = re.search(r'"?sign"?\s*[:=]\s*["\']([\w-]+)', html) is not None
    is_protected = bool(re.findall(r'\baccess-code\b', html))
    return has_sign or is_protected

Try / catch

try:
    baidu_pan_download(url)
except AssertionError as e:
    if 'Share not found or canceled' in str(e):
        # dead link: surface to user / drop from queue, do not retry
        mark_share_dead(url)
    else:
        raise

Prevention

When it happens

Trigger: Calling baidu_pan_download with a pan.baidu.com share URL that was deleted/canceled by its owner, never existed, or whose page layout changed so baidu_pan_parse can no longer find the sign regex AND the page lacks r'\baccess-code\b'. Only raised when isprotected stays False.

Common situations: Expired Baidu cloud shares (very common), mistyped share link (wrong uk/id), Baidu changing the share page HTML so the parse regexes break, or a protected share whose access-code marker is not detected due to markup change.
