访问登录页面失败

Error message

访问登录页面失败: %w

What it means

Step 1 of gying login performs a GET of the site's login page via requestWithChallengeRetry (which handles Cloudflare challenges). If that request fails at the transport level (connection error, timeout, challenge not solvable), the error is wrapped as '访问登录页面失败: %w' and the login aborts before any credentials are sent.

Solutions

1. Verify basic connectivity to the site base URL (curl -I <baseURL>, with the same proxy if configured).
2. Check the proxy: it may be down or too slow, causing request timeouts — switch or disable it.
3. Re-run with DebugLog enabled to see how many challenge retries were attempted and the underlying error.
4. Update the plugin/cloudscraper so the Cloudflare challenge solver matches the site's current protection level.
5. Retry later if the site itself is temporarily down or rate-limiting your IP.

var lastErr error
for i := 0; i < 3; i++ {
    res, err := gyingLogin(ctx, creds)
    if err == nil {
        return res, nil
    }
    lastErr = err
    if !strings.Contains(err.Error(), "访问登录页面失败") || !isTransient(err) {
        return err
    }
    time.Sleep(time.Duration(1<<i) * time.Second)
}
return lastErr

When it happens

Trigger: Calling gying login when the GET to loginPageURL errors in requestWithChallengeRetry — network unreachable, DNS failure, TLS error, or exhausted challenge-retry attempts.

Common situations: Site blocked or down; proxy offline; Cloudflare returns an unsolvable challenge repeatedly; corporate firewall or GFW interference; DNS pollution of the site domain.
