[ ] 第 页搜索请求失败

Error message

[%s] 第%d页搜索请求失败: %w

What it means

This error wraps a failed per-page HTTP search request in the yunsou plugin's fetchPage. doRequestWithRetry exhausted all retry attempts (network error or non-200 status) and the underlying failure is chained with %w so the root cause (e.g. the '重试 %d 次后仍然失败' error) is preserved. It indicates the plugin could not retrieve the HTML for that search page at all.

Solutions

1. Inspect the wrapped cause (%w chain) to see if it is a timeout, connection error, or bad status code.
2. Verify network connectivity and that wpys.cc is reachable (curl -I https://wpys.cc/).
3. Update/rotate User-Agent, Referer, and other headers if the site added anti-bot protection.
4. Increase maxRetries or retry backoff in doRequestWithRetry for flaky networks.
5. Reduce requested pages so one bad page does not fail the whole search.

Example fix

// before
return nil, fmt.Errorf("[%s] 第%d页搜索请求失败: %w", p.Name(), page, err)
// after
var resp *http.Response
resp, err = p.doRequestWithRetry(req, client)
if err != nil {
    log.Printf("[%s] 第%d页搜索请求失败(跳过): %v", p.Name(), page, err)
    return nil, nil // degrade gracefully instead of aborting search
}

func checkReachable(url string) error {
    resp, err := http.Head(url)
    if err != nil { return err }
    defer resp.Body.Close()
    if resp.StatusCode != 200 { return fmt.Errorf("站点状态码 %d", resp.StatusCode) }
    return nil
}

doc, err := p.fetchPage(client, keyword, page)
if err != nil {
    log.Printf("跳过第%d页: %v", page, err)
    return resultsSoFar, nil // partial results instead of abort
}

When it happens

Trigger: doRequestWithRetry returns an error after maxRetries failures in fetchPage — all attempts timed out, connection was refused/reset, or every retry returned a non-200 status code.

Common situations: Site wpys.cc is down or blocked, the User-Agent/Referer anti-scrape headers are no longer sufficient and the site returns 403/503, DNS failure, or the machine has no internet/proxy access.

Understand the failure class

Background: 'Something went wrong' / 'Request failed (500)' / 'HTTP error! status: 404' — what failed HTTP requests actually mean and how to find the real cause — this error's family across 28 libraries.
