[ ] 搜索返回状态码

Error message

[%s] 搜索返回状态码: %d

What it means

The duanjuw plugin returns this when the search response status code is not 200. Any non-OK status (403 WAF block, 429 rate limit, 5xx) is treated as a failed search since the plugin expects an HTML results page.

Solutions

1. Map the status: 403 → blocked, change headers/cookies/IP; 429 → back off and slow down; 5xx → retry later
2. Verify setDuanjuwHeaders produces browser-like Referer and User-Agent
3. Reduce search frequency or add caching for repeated keywords
4. Re-check the site manually; if it now requires JS challenge, the plugin needs updating

Example fix

// before
if err != nil { return err }
// after
var statusErr interface{ Error() string }
if strings.Contains(err.Error(), "搜索返回状态码: 429") {
    time.Sleep(time.Minute)
    items, err = p.searchImpl(k)
}

// probe status before searches
resp, err := client.Get(duanjuwBaseURL + "/")
if err == nil {
    if resp.StatusCode == 403 || resp.StatusCode == 429 { log.Println("currently blocked/rate-limited") }
    resp.Body.Close()
}

if err != nil && strings.Contains(err.Error(), "搜索返回状态码: 429") {
    select {
    case <-time.After(time.Minute):
        return p.searchImpl(k)
    case <-ctx.Done():
        return ctx.Err()
    }
}

When it happens

Trigger: doDuanjuwRequestWithRetry succeeded at transport level but resp.StatusCode != http.StatusOK in searchImpl.

Common situations: Anti-bot protection blocking datacenter IPs; too-frequent searches hitting a rate limit; site returning 5xx during incidents; redirect to a login or verification page.
