跳转接口返回无效链接

Error message

跳转接口返回无效链接

What it means

Validation guard in ting77 resolveLink: a redirect was received and Location was non-empty, but url.Parse failed or the URL lacks scheme/host. The redirect target itself is malformed — a relative or garbage Location header.

Solutions

1. Resolve relative Locations against the request URL before validating
2. Skip entries whose redirect target stays malformed
