[ ] API 失败且网页搜索没有有效资源 (API: )

Error message

[%s] API 失败且网页搜索没有有效资源 (API: %v)

What it means

After the primary API call failed and the plugin fell back to scraping the web search page, zero parseable results were found. The plugin wraps both failures into this combined error because it has no usable data to return.

Solutions

1. Inspect the fallback page HTML and update the plugin's CSS selectors to the current markup.
2. Check whether the site serves a captcha/anti-bot page and add proper headers/cookies.
3. Retry later or with a different keyword to distinguish 'no results' from a broken scraper.
4. Fix the primary API error (apiErr) so the fallback is not required.

// probe the fallback page and count expected selector matches
n := doc.Find("div.result-item").Length()
if n == 0 {
    log.Println("fallback page returned no items; markup may have changed")
}

results, err := searchImpl(keyword)
if err != nil {
    if strings.Contains(err.Error(), "没有有效资源") {
        log.Printf("no results and API down: %v", err)
        return emptyOrCachedResults()
    }
    return err
}

When it happens

Trigger: searchWeb: the API errored (apiErr non-nil) AND the DOM selector pass over the fallback HTML matched no result items (len(results) == 0).

Common situations: Site markup changed so the CSS selectors (.bm-file, .ext-meta, etc.) no longer match; the site served a captcha or empty results page; keyword genuinely has no results but is wrapped with the API error.

Understand the failure class

Background: EmptyResultError / "no results found": when an API or scraper succeeds but returns zero rows — this error's family across 9 libraries.
