提取登录信息失败

Error message

提取登录信息失败: %w

What it means

In checkQRLoginStatus (plugin/qqpd/qqpd.go:1798), when the QR-login response contains '登录成功', the plugin calls extractLoginInfo to pull ptsigx and uin from the ptuiCB callback. If that parsing fails, the error is wrapped as '提取登录信息失败: %w'. It means QQ's login response was reported successful but its body did not match the expected ptuiCB format.

Solutions

1. Log the full response body (the plugin already prints it) and check whether the ptuiCB format changed
2. Update the regexes in extractLoginInfo to match the current QQ response format
3. Re-generate the QR code and retry the login — a stale/expired QR can yield malformed responses
4. Check for a pending confirmation state (user must confirm on the phone) before parsing

Example fix

// before
return nil, fmt.Errorf("提取登录信息失败: %w", err)
// after
return nil, fmt.Errorf("提取登录信息失败 (响应: %.200s): %w", bodyStr, err)

user, err := p.checkQRLoginStatus(qrsig)
if err != nil {
    if strings.Contains(err.Error(), "提取登录信息失败") {
        // log the raw response and fall back to re-issuing the QR code
    }
    return err
}

When it happens

Trigger: handleCheckLogin polls checkQRLoginStatus; the response body contains '登录成功' but extractLoginInfo fails to find ptuiCB(...), the URL, ptsigx, or uin in it.

Common situations: QQ changed the ptqrlogin response format, a login confirmation step is pending so the URL lacks the expected query parameters, or an HTML error/captcha page is returned despite the success marker.
