[ ] 搜索失败

Error message

[%s] 搜索失败: %w

What it means

Returned by XiaokupanPlugin.searchImpl when the search against xiaokupan.com fails after the automatic function-ID refresh path has been exhausted (or the refresh succeeded but the retry with the fresh ID also failed). It wraps the final search error with %w and prefixes the plugin name.

Solutions

1. Look at the wrapped cause (%w chain): 请求失败 = network, HTTP NNN = status, 解析/读取 errors = transport, 解析 Seroval 响应失败 = upstream changed response shape
2. Curl the endpoint manually: https://xiaokupan.com/_serverFn/<functionID>?payload=... to see what the server returns
3. If HTTP 404/400, the function ID is stale — confirm refreshServerFunctionID can discover a new one from the site's entry JS
4. If the Seroval shape changed, update parseSearchResponse to match the new response structure
5. Retry later for transient 5xx/timeout cases

func canReachXiaokupan() error {
    resp, err := http.Head("https://xiaokupan.com/")
    if err != nil { return err }
    defer resp.Body.Close()
    if resp.StatusCode != http.StatusOK { return fmt.Errorf("homepage HTTP %d", resp.StatusCode) }
    return nil
}

results, err := plugin.SearchWithResult(keyword, ext)
if err != nil {
    // %w chain reveals root cause: 请求失败/HTTP NNN/解析... failure
    log.Printf("xiaokupan search failed: %v", err)
    time.Sleep(2 * time.Second)
    results, err = plugin.SearchWithResult(keyword, ext) // one retry
    if err != nil { return otherSources(keyword) }
}

When it happens

Trigger: Either the first searchWithFunctionID attempt failed, refresh succeeded, and the retry with the refreshed ID also failed — or the first attempt failed and the refreshed-ID retry itself errored. Root causes come from searchWithFunctionID: payload construction, URL parse, request creation, doLimitedRequest (network/HTTP/size), or parseSearchResponse (Seroval decode).

Common situations: Upstream site temporarily down or returning 5xx; stale server-function hash even after refresh (site changed its bundle layout); response exceeds the 4MB maxSearchResponseSize cap; keyword produces a payload the endpoint rejects.
