[ ] 搜索请求失败

Error message

[%s] 搜索请求失败: %w

What it means

searchImpl wraps any error returned by doRequestWithRetry for the alupan search request. It means the HTTP GET to www.aliupan.com failed on every retry attempt — network-level failure or timeout — before any response body could be processed. The underlying cause is preserved via %w.

Solutions

1. Inspect the wrapped error (errors.Is for context.DeadlineExceeded, *net.OpError, etc.) to identify the root cause.
2. Test reachability: curl -v 'https://www.aliupan.com/?s=test' from the deployment host; check proxy env vars.
3. Increase searchTimeout (currently 12s) or searchMaxRetries (3) if failures are transient/slow-network.
4. Check for anti-bot/Cloudflare challenges; add appropriate headers or cookies in setCommonHeaders if the site began blocking.
5. Fall back gracefully — skip this plugin and aggregate results from other plugins when it fails.

Example fix

// before
resp, err := p.doRequestWithRetry(req, client, searchMaxRetries)
// after
resp, err := p.doRequestWithRetry(req, client, searchMaxRetries)
if errors.Is(err, context.DeadlineExceeded) {
    // bump searchTimeout or retry with a fresh context
}

// Quick pre-flight before running the full search
ctx, cancel := context.WithTimeout(context.Background(), 3*time.Second)
defer cancel()
req, _ := http.NewRequestWithContext(ctx, http.MethodHead, "https://www.aliupan.com/", nil)
if _, err := http.DefaultClient.Do(req); err != nil {
    log.Printf("aliupan unreachable: %v", err) // skip plugin or alert
}

// Go: classify the wrapped transport error and fall back
if err != nil {
    switch {
    case errors.Is(err, context.DeadlineExceeded):
        log.Println("aliupan: request timed out after retries")
    case errors.Is(err, syscall.ECONNREFUSED):
        log.Println("aliupan: connection refused")
    default:
        log.Printf("aliupan: request failed: %v", err)
    }
    // continue with other plugins' results
}

When it happens

Trigger: doRequestWithRetry exhausts searchMaxRetries (3) because of DNS failure, connection refused/reset, TLS handshake timeout, or the 12-second searchTimeout context/client deadline expiring on each attempt.

Common situations: aliupan.com is down, geo-blocked, or rate-limiting the host; the deployment environment has no internet egress; a corporate proxy intercepts HTTPS; the 12s timeout is too short on a slow connection; site started requiring cookies/JS challenge (Cloudflare).

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.
