HTTP 403 Forbidden - 需要重新登录

Error message

HTTP 403 Forbidden - 需要重新登录

What it means

The search response body passed isLoginShell(body) — i.e. it looks like the login page shell rather than search results. The plugin interprets this as the server having redirected to login because the session is invalid, and reports it as a 403-like condition requiring re-login.

Solutions

1. Re-login to refresh the session cookie (the plugin's 403-recovery path handles this).
2. Avoid using the same account from multiple clients that invalidate each other's sessions.
3. Persist cookies across restarts so sessions are reused while valid.
4. Verify credentials are still valid in case the account was logged out everywhere.

results, err := p.Search(keyword)
if err != nil && strings.Contains(err.Error(), "需要重新登录") {
    if rlErr := p.reloginUser(user); rlErr != nil {
        return rlErr
    }
    results, err = p.Search(keyword)
}

When it happens

Trigger: searchWithScraper gets HTTP 200 but the HTML is the login shell (session silently invalidated); the code detects isLoginShell(body) and returns this error before attempting JSON extraction.

Common situations: Site logs out sessions server-side ( kicked by concurrent login ); cookies cleared/rotated; site redirects unauthenticated requests to the login page instead of returning 403.

Understand the failure class

• HTTP status errors: handling 4xx and 5xx responses — how to handle 4xx and 5xx responses properly.
• Authentication and authorization failures — expired tokens, bad credentials, and missing scopes.
