[ ] 创建网页搜索请求失败

Error message

[%s] 创建网页搜索请求失败: %w

What it means

searchWeb is the HTML scraping fallback used when the JSON API path fails; it builds a second request to SearchWebURL and wraps any construction error in this message. As with the API path, this fires before any bytes hit the network.

Solutions

1. Validate the composed searchURL with url.Parse before creating the request
2. Check the SearchWebURL constant and query string composition
3. Confirm url.QueryEscape is applied to all user-supplied parts

Example fix

// before
searchURL := SearchWebURL + "?wd=" + url.QueryEscape(keyword) + "&ext=1"
req, err := http.NewRequestWithContext(ctx, http.MethodGet, searchURL, nil)
// after
u, uerr := url.Parse(SearchWebURL)
if uerr != nil {
    return nil, fmt.Errorf("invalid SearchWebURL %q: %w", SearchWebURL, uerr)
}
q := u.Query(); q.Set("wd", keyword); q.Set("ext", "1"); u.RawQuery = q.Encode()
req, err := http.NewRequestWithContext(ctx, http.MethodGet, u.String(), nil)

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

results, err := plugin.Search(keyword)
if err != nil && strings.Contains(err.Error(), "创建网页搜索请求失败") {
    return nil, fmt.Errorf("feikuai web fallback misconfigured: %w", err)
}

When it happens

Trigger: http.NewRequestWithContext(ctx, http.MethodGet, SearchWebURL+"?wd="+url.QueryEscape(keyword)+"&ext=1", nil) fails — malformed URL composition or illegal characters after concatenation.

Common situations: Stale or mistyped SearchWebURL constant, keyword containing characters that break the URL even after QueryEscape (e.g. embedded control chars), domain rotation mistakes.

Understand the failure class

Background: "Invalid URL" / "URL cannot be empty": fix the malformed or missing URL behind request-construction failures — this error's family across 50 libraries.
