[ ] 执行搜索失败

Error message

[%s] 执行搜索失败: %w

What it means

searchImpl in the javdb plugin wraps any non-rate-limited failure from executeSearchWithRateLimit as '[javdb] 执行搜索失败: %w' (search execution failed). It is the top-level error aggregator for the search step; rate-limited runs (isRateLimited=true) are deliberately not wrapped because partial results are still processed.

Solutions

1. Unwrap the %w cause to find which inner step failed
2. Curl the javdb search URL with the same headers to check reachability/blocking
3. Verify the search URL and User-Agent still match the current site behavior
4. Increase the client timeout if failures correlate with slow responses
5. Treat this error in callers as 'source temporarily unavailable' and fall back to other plugins

// Go: check source reachability before invoking search
resp, err := http.Head("https://javdb.com")
if err != nil || resp.StatusCode >= 400 {
    log.Printf("javdb unreachable, skipping")
}

func isSearchExecFailure(err error) bool {
    return err != nil && strings.Contains(err.Error(), "执行搜索失败")
}

results, err := p.searchImpl(client, keyword)
if err != nil {
    var inner error = errors.Unwrap(err)
    log.Printf("javdb search failed (cause=%v): %v", inner, err)
    return nil, err
}

When it happens

Trigger: executeSearchWithRateLimit returns an error with isRateLimited=false — e.g. request creation failure, client.Do transport error, non-200 status, body read failure, or HTML parse failure.

Common situations: javdb blocks or changes its endpoint; network egress blocked in the container; HTTP client timeout too short; site returns 5xx or a bot-block page; goquery fails on an unexpected response.

Understand the failure class
