提交验证失败

Error message

提交验证失败: %w

What it means

Wraps the transport error returned by cloudscraper's POST when submitting the solved bot-challenge verification form. It means the verification request never got an HTTP response (connection, TLS, timeout, or proxy failure). The library wraps the underlying cause with %w so callers can unwrap it.

Solutions

1. Unwrap the error with errors.Unwrap/As to find the root cause (e.g. *url.Error, net.Error, x509 errors).
2. Verify the proxy settings applied to the scraper are reachable and correct.
3. Retry the request with backoff; these are usually transient network failures.
4. Check DNS/TLS connectivity to the target site (curl the same URL).

if u, err := url.Parse(requestURL); err != nil || (u.Scheme != "http" && u.Scheme != "https") { return fmt.Errorf("invalid request URL for challenge submit") }

var netErr net.Error; if errors.As(err, &netErr) && netErr.Timeout() { /* retry with backoff */ }

if err := p.doRequest(); err != nil { var wrapped *fmt.wrapError; if errors.As(err, &wrapped) { log.Printf("submit failed: %v", errors.Unwrap(err)) }; if isRetryable(err) { time.Sleep(backoff); retry() } }

When it happens

Trigger: submitChallengeVerification calls scraper.Post(requestURL, "application/x-www-form-urlencoded", ...) and err != nil, i.e. before any HTTP status is available, during challenge verification against the site.

Common situations: Site unreachable from the host, invalid/unreachable proxy configured via applyProxyToScraper, TLS interception or cert issues, DNS failure, or transient network drops during anti-bot verification.
