Unsupported url

Error message

Unsupported url

What it means

Raised as plain Exception in ku6_download (src/you_get/extractors/ku6.py:47). For new-style www.ku6.com detail pages, the code scrapes an inline `detailDataMap={...};` JS object from the HTML; if that regex finds nothing, the page shape is unrecognized and the URL is rejected before any video metadata can be read.

Solutions

  1. Open the URL in a browser and confirm the video page (with metadata) is actually served.
  2. curl the page with the same headers and grep for detailDataMap; if gone, the page became JS-rendered — the extractor needs updating (or use the v.ku6.com canonical URL form).
  3. Prefer canonical v.ku6.com/show/... URLs which use the id-based path instead of page scraping.
Defensive patterns

Strategy: try-catch

Validate before calling

import re
from you_get.common import get_content

def ku6_page_has_detail_map(url):
    page = get_content(url)
    return re.search(r'detailDataMap=(\{.+?\});', page) is not None, page

Try / catch

try:
    ku6_download(url, output_dir)
except Exception as e:
    if str(e) == 'Unsupported url' and 'v.ku6.com' not in url:
        ku6_download(canonicalize_to_v_ku6(url))  # or flag site redesign
    else:
        raise

Prevention

When it happens

Trigger: Calling ku6_download with a ku6.com URL that (a) matches none of the v.ku6.com/my.ku6.com id patterns, and (b) whose fetched HTML does not contain r'detailDataMap=(\{.+?\});' — e.g. ku6 redesigned the page, serves a JS-rendered shell, or returns an error/geo-block page.

Common situations: ku6.com site redesign removing the inline detailDataMap; bot detection returning an empty shell; old dead links redirecting to the homepage.
