发送搜索请求失败

Error message

发送搜索请求失败: %w

What it means

searchImpl in the leijing plugin wraps any error from p.doRequest (which performs the HTTP GET against the search URL) with this message. It signals the HTTP request itself failed before a response was obtained. The original transport error is preserved via %w.

Solutions

1. Inspect the wrapped cause from %w to see the transport-level reason
2. Test the search URL with curl from the same host to confirm reachability
3. Increase the HTTP client timeout or configure a proxy if egress is restricted
4. Check if the site blocks automated clients and adjust headers (User-Agent, Referer)
5. If the domain changed, update the BaseURL/searchURL constants in the plugin

u, err := url.Parse(searchURL)
if err != nil || u.Host == "" {
    return fmt.Errorf("invalid search URL: %q", searchURL)
}

results, err := plugin.Search(ctx, keyword)
if err != nil {
    if errors.Is(err, context.DeadlineExceeded) {
        return fmt.Errorf("leso search timed out: %w", err)
    }
    var netErr net.Error
    if errors.As(err, &netErr) && netErr.Timeout() {
        // retry with a longer timeout
    }
    return err
}

When it happens

Trigger: p.doRequest(client, searchURL, BaseURL) returns a non-nil error during a keyword search: connection refused/reset, timeout, DNS failure, TLS error, or proxy failure.

Common situations: The leijing upstream site is unreachable or has changed domain; corporate firewall blocks egress; client timeout too short; site requires different TLS settings (e.g. TLS fingerprinting blocked Go's default client).
