创建验证请求失败

Error message

创建验证请求失败: %w

What it means

solveVerification builds a GET http.Request for the verification endpoint with http.NewRequestWithContext. If request construction fails (invalid method/URL), the error is wrapped as 创建验证请求失败. This indicates the constructed verifyURL is not a valid absolute HTTP URL.

Solutions

  1. Ensure the pageURL passed to getDetailInfo/searchSuggest includes an absolute scheme (https://)
  2. Log verifyURL before request creation to spot missing scheme/host
  3. Fallback to "https" if parsedPage.Scheme is empty

Example fix

// before
verifyURL := (&url.URL{Scheme: parsedPage.Scheme, Host: parsedPage.Host, Path: endpointPath}).String()
// after
scheme := parsedPage.Scheme
if scheme == "" {
    scheme = "https"
}
verifyURL := (&url.URL{Scheme: scheme, Host: parsedPage.Host, Path: endpointPath}).String()
Defensive patterns

Strategy: validation

Validate before calling

u, err := url.Parse(rawURL)
if err != nil || u.Scheme == "" || u.Host == "" {
    return fmt.Errorf("url must be absolute: %w", err)
}

Try / catch

info, err := plugin.GetDetailInfo(ctx, url)
if err != nil && strings.Contains(err.Error(), "创建验证请求失败") {
    log.Printf("verification request could not be built for %s: %v", url, err)
}

Prevention

When it happens

Trigger: http.NewRequestWithContext returns an error — typically because parsedPage had an empty/invalid Scheme or Host so the reconstructed verifyURL is not absolute (e.g. missing scheme).

Common situations: Page URL was scheme-relative (//host/path) so parsedPage.Scheme is empty; pageURL had no host (e.g. a relative path leaked in); programmatic URL reconstruction dropped the scheme.

Understand the failure class

Background: "Invalid URL" / "URL cannot be empty": fix the malformed or missing URL behind request-construction failures — this error's family across 50 libraries.
