[ ] 解析搜索 JSON 失败

Error message

[%s] 解析搜索 JSON 失败: %w

What it means

The response body was read but jsonutil.Unmarshal could not decode it into lou1SearchResponse. The plugin expected a JSON search API payload; anything else (HTML error page, Cloudflare challenge, changed schema) triggers this error.

Solutions

1. Log the first bytes of body to see what actually came back (HTML challenge? partial JSON?)
2. Compare the live API response against the lou1SearchResponse struct; update fields/json tags if the schema changed
3. Confirm search URL points at the JSON API endpoint, not an HTML page
4. Check Content-Type and encoding handling (gzip) on the client transport

Example fix

// before
type lou1SearchResponse struct {
    OK   bool `json:"ok"`
    Data struct{ Hits []searchThread `json:"hits"` } `json:"data"`
}
// after — match renamed upstream fields
type lou1SearchResponse struct {
    OK   bool `json:"success"`
    Data struct{ Hits []searchThread `json:"results"` } `json:"data"`
}

// before parsing
c.Header.Set("Accept", "application/json")

results, err := lou1.Search(kw)
if err != nil && strings.Contains(err.Error(), "解析搜索 JSON 失败") {
    if bytes.HasPrefix(body, []byte("<")) {
        log.Printf("lou1 returned HTML — anti-bot page or endpoint moved")
    }
    return err
}

When it happens

Trigger: Body is not valid JSON or its structure does not match lou1SearchResponse fields (types or nesting differ).

Common situations: WAF/anti-bot returned an HTML challenge instead of JSON; site changed the search API response shape; response is gzip-compressed and not decompressed; truncated body.
