[ ] API JSON 解析失败

Error message

[%s] API JSON 解析失败: %w

What it means

searchImpl unmarshals the API body into FeikuaiAPIResponse; if the payload is not valid JSON or does not match the struct, it falls back to searchWeb with this wrapped error. It means the endpoint answered but not with the expected JSON schema.

Solutions

1. Log a snippet of body on failure to see what was actually returned
2. Check Content-Type; handle non-JSON (HTML challenge) explicitly
3. Verify FeikuaiAPIResponse fields still match the current API schema
4. If Content-Encoding is gzip and not auto-decompressed, wrap with gzip.NewReader

Example fix

// before
var apiResp FeikuaiAPIResponse
if err := json.Unmarshal(body, &apiResp); err != nil {
    return p.searchWeb(client, keyword, fmt.Errorf("[%s] API JSON 解析失败: %w", p.Name(), err))
}
// after
var apiResp FeikuaiAPIResponse
if err := json.Unmarshal(body, &apiResp); err != nil {
    log.Printf("feikuai non-JSON response (first 200B): %.200s", body)
    return p.searchWeb(client, keyword, fmt.Errorf("[%s] API JSON 解析失败: %w", p.Name(), err))
}

ct := resp.Header.Get("Content-Type")
if !strings.Contains(ct, "application/json") {
    return fmt.Errorf("expected JSON, got %q", ct)
}
if len(body) == 0 { return fmt.Errorf("empty body") }

func looksLikeFeikuaiAPI(b []byte) bool {
    var probe struct { Code int `json:"code"` }
    return json.Unmarshal(b, &probe) == nil
}

results, err := plugin.Search(keyword)
if err != nil && strings.Contains(err.Error(), "JSON 解析失败") {
    log.Printf("feikuai returned non-JSON (likely challenge page); using fallback results: %v", err)
}

When it happens

Trigger: json.Unmarshal(body, &apiResp) fails — HTML error page instead of JSON, empty body, changed field types (e.g. code became string), gzip content not auto-decompressed.

Common situations: Site replaced API with an HTML challenge page (anti-bot), API version change altering the response shape, proxy injecting a captive-portal page.
