盘链 token 为空

Error message

盘链 token 为空

What it means

resolvePanToken rejects an empty token with '盘链 token 为空' ('panlian token is empty'). A pan group entry contained no usable token/URL after trimming, so there is nothing to resolve into a real pan link.

Solutions

1. Skip entries with empty tokens in resolvePanLinkTokens instead of failing the whole resolution.
2. Log and drop malformed groups; verify the upstream response for that item.
3. Update the PanGroup struct/parsing if upstream renamed the token field.
4. Report the resource as having no links rather than surfacing an error to the user.

Example fix

// before
resolved, err := p.resolvePanToken(client, cookie, token)
if err != nil { return err }
// after
if strings.TrimSpace(token) == "" { continue } // skip empty entries
resolved, err := p.resolvePanToken(client, cookie, token)

// filter entries before resolution
usable := groups[:0]
for _, g := range groups {
    if strings.TrimSpace(g.Token) != "" {
        usable = append(usable, g)
    }
}

func hasToken(g PanGroup) bool {
    return strings.TrimSpace(g.Token) != ""
}

url, err := plugin.ResolveToken(ctx, token)
if err != nil && strings.Contains(err.Error(), "盘链 token 为空") {
    continue // skip empty entry, keep processing other groups
}

When it happens

Trigger: resolvePanLinkTokens iterates groups and encounters a PanGroup item whose token field is empty or whitespace-only; upstream returned a group with missing token data.

Common situations: panlian listing includes placeholder/empty entries for items whose links were removed; JSON schema drift leaving token fields unset; scraping a deleted resource.
