无法解析code字段，类型: %T, 值

Error message

无法解析code字段，类型: %T, 值: %v

What it means

The parsed login JSON stores its 'code' field as interface{}, so gying converts it via fmt.Sprintf("%v") + strconv.Atoi. If the value is neither a number nor a numeric string (e.g. bool, nested object, or missing→nil), Atoi fails and the plugin returns '无法解析code字段，类型: %T, 值: %v', reporting the Go type and value it couldn't parse.

Solutions

1. Log the full raw response body and check the actual shape of the 'code' field against the error's %T/%v output.
2. Compare with the site's current API docs or a manual login (browser devtools) to see the new response schema.
3. Update the plugin to handle the new schema (e.g. accept string statuses or a renamed field).
4. If the field is missing entirely, the endpoint likely returned an error payload — fix the request (credentials, cookies) and retry.

Example fix

// before: only numeric/string-numeric accepted
parsed, err := strconv.Atoi(codeStr)
// after: also treat a bool-style or mapped status defensively
if s, ok := codeInterface.(string); ok {
    parsed, err = strconv.Atoi(strings.TrimSpace(s))
}

func codeFieldIsNumeric(loginResp map[string]interface{}) bool {
    switch v := loginResp["code"].(type) {
    case float64, int, string:
        return true
    default:
        _ = v
        return false
    }
}

When it happens

Trigger: Login response JSON contains a 'code' field whose value is not numeric — a string like "ok", an object, a boolean, or the field is absent so codeInterface is nil.

Common situations: Site changed its login API response schema (code moved/renamed, became a string status); response is actually an error payload with a different shape; partial/HTML-ish body that unmarshaled as something unexpected.
