invalid url for yinyuetai

Error message

invalid url for yinyuetai

What it means

The YinYueTai extractor only accepts three URL shapes: v.yinyuetai.com/video/<id>, v.yinyuetai.com/video/h5/<id>, and m2.yinyuetai.com/video.html?id=<id>. If none of the three regexes matches, the video id cannot be extracted and this error is returned before any network call is made.

Solutions

1. Rewrite the URL to the canonical form https://v.yinyuetai.com/video/<id> before extracting
2. Confirm the URL opens a video page in a browser
3. If the domain layout changed permanently, add the new pattern to the MatchOneOf call in extractors/yinyuetai/yinyuetai.go
4. Validate the URL against the three patterns on the caller side first

Example fix

// before
_, err := yinyuetai.Extract("https://www.yinyuetai.com/video/2515284", opts) // wrong host -> error

// after
_, err := yinyuetai.Extract("https://v.yinyuetai.com/video/2515284", opts) // matches first pattern

var yinyuetaiRe = regexp.MustCompile(`^https?://(v\.yinyuetai\.com/video/(h5/)?\d+(\?vid=\d+)?$|https?://m2\.yinyuetai\.com/video\.html\?id=\d+)`)

func isYinyuetaiVideoURL(raw string) bool {
    return yinyuetaiRe.MatchString(raw)
}

if !isYinyuetaiVideoURL(url) {
    // rewrite to canonical https://v.yinyuetai.com/video/<id> or reject
}
_, err := yinyuetai.Extract(url, opts)

When it happens

Trigger: Passing a www.yinyuetai.com host, a fan/stage page, a URL with the id in an unexpected query param, or any post-rebrand domain layout that no longer matches the three patterns.

Common situations: YinYueTai rebranded/reorganized its site so canonical video permalinks changed; users paste search-result or playlist URLs; trailing fragments or encoded characters break the match.
