[ ] 执行搜索失败

Error message

[%s] 执行搜索失败: %w

What it means

searchImpl wraps any failure from p.executeSearch(keyword) with this error, preserving the underlying cause via %w and prefixing the plugin name. It is the outer boundary error for the first phase of a Diduan search: fetching and extracting the result list.

Solutions

1. Unwrap the error (errors.Unwrap or %w chain) to see whether it was a request failure, HTTP status, or parse failure.
2. If the message mentions a Cloudflare Managed Challenge, pause and retry later or improve scraper stealth/proxy setup.
3. Verify BaseURL/SearchPath still match the live site's endpoints.
4. Add retries/backoff for transient network errors.

Example fix

// before
results, err := p.Search(keyword)
if err != nil { return err }
// after
results, err := p.Search(keyword)
if err != nil {
    log.Printf("diduan search failed: %v", err) // %w chain shows root cause
    return err
}

results, err := p.Search(keyword)
if err != nil {
    log.Printf("search failed: %+v", err) // preserve wrap chain
    if strings.Contains(err.Error(), "Managed Challenge") {
        // cool-down / proxy rotation path
    }
    return err
}

When it happens

Trigger: executeSearch returns an error — the page request failed (wrapped 搜索请求失败), a non-200 status or Cloudflare challenge occurred (httpStatusError), or goquery HTML parsing failed — and searchImpl propagates it wrapped.

Common situations: Cloudflare challenge pages returned to the scraper; site layout change causing parse or empty responses; network outages; the search endpoint URL changed so requests 404.

Understand the failure class

Background: "API request failed": what wrapped HTTP errors from external APIs mean and how to find the real cause — this error's family across 29 libraries.
