[ ] 执行搜索失败

Error message

[%s] 执行搜索失败: %w

What it means

Generic wrapper in dyyj.searchImpl for any failure returned by p.executeSearch (which itself may use HTML scraping or the Flarum JSON API). The inner error is preserved via %w, so this is a contextual wrapper, not a distinct failure. It indicates the whole search pipeline for this plugin failed.

Solutions

1. Inspect the wrapped cause with errors.Unwrap / %v of the returned error — fix the root cause first
2. Run with debugMode=true to get the pre-wrap log line identifying the failing stage
3. Verify network access to BaseURL from the host (curl the search URL)
4. Check whether the site/API changed and update selectors or API params
5. Ensure doRequestWithRetry backoff is adequate for a rate-limited site

Example fix

// before
results, err := plugin.Search(ctx, keyword)
if err != nil {
	log.Fatal(err)
}
// after
results, err := plugin.Search(ctx, keyword)
if err != nil {
	var rootErr error
	for e := err; e != nil; e = errors.Unwrap(e) {
		rootErr = e
	}
	log.Fatalf("search failed: %v (root cause: %v)", err, rootErr)
}

url, err := url.Parse(pluginBaseURL); if err != nil || url.Host == "" { return errors.New("plugin base URL invalid") }

results, err := p.searchImpl(ctx, keyword)
if err != nil {
	log.Printf("[%s] search failed: %v", p.Name(), err) // %v shows the full wrap chain
	return nil, err
}

When it happens

Trigger: Any underlying cause inside executeSearch: request construction failure, network error after retries, non-200 status, HTML/JSON parse failure, or empty results path that returns an error.

Common situations: Site blocked the client (cloudflare challenge); API endpoint changed; keyword triggers server-side rate limiting; network/proxy outage in the deployment environment.

Understand the failure class
