not find data

Error message

not find data

What it means

htmlJsonToMap2 extracts data blobs from the LanZou page via findDataReg and picks the longest match; this error means zero matches were found, so there is no JSON-ish data to parse into a parameter map.

Solutions

1. Verify the share link still opens normally in a browser
2. If the share needs a password, ensure the password is provided in the storage/link config so the correct flow runs
3. Update OpenList to pick up lanzou parser fixes; report the HTML if already current

func hasLanzouDataBlob(html string) bool {
    return findDataReg.MatchString(html)
}

m, err := htmlJsonToMap2(html)
if err != nil {
    if !hasLanzouDataBlob(html) {
        // error/challenge template: retrying blindly will not help
        return nil, fmt.Errorf("unexpected lanzou page (deleted or challenge): %w", err)
    }
    return nil, err
}

When it happens

Trigger: The share/download page HTML contains no data assignments matching findDataReg — the page is an error template, a challenge page, a password prompt, or LanZou changed how data is embedded.

Common situations: Share link deleted or privatized; wrong share password flow reaching this function; LanZou frontend change moving data into JS variables or fetch calls; rate-limited response body.
