无法提取qrid

Error message

无法提取qrid

What it means

Raised by generateQRCodeWithSig when the regex "qrid":"([^"]+)" finds no qrid in the info page body. api_key extraction succeeded (error 751 did not fire), but the qrid needed to poll QR scan status is absent, so QR generation aborts. This means the endpoint response is missing the expected qrid JSON field.

Solutions

1. Dump infoText on failure to inspect the actual response structure around qrid.
2. Update the qrid regex/parsing to match the current response format (e.g. accept qrid without quotes or nested JSON).
3. Re-request the info page with proper headers/cookies; a stale or anonymous session may get a degraded response.
4. Retry generation once — transient truncation or a race with session setup can omit qrid.

Example fix

// before
qridMatch := qridRegex.FindStringSubmatch(infoText)
if len(qridMatch) < 2 {
    return nil, "", fmt.Errorf("无法提取qrid")
}
// after: accept both quoted JSON and bare forms
qridRegex := regexp.MustCompile(`"?qrid"?\s*[=:]\s*"?([A-Za-z0-9_-]+)`)
qridMatch := qridRegex.FindStringSubmatch(infoText)
if len(qridMatch) < 2 {
    return nil, "", fmt.Errorf("无法提取qrid, 响应长度: %d", len(infoText))
}

// Go: confirm qrid is present in the body before relying on it
if !strings.Contains(infoText, "qrid") {
    return fmt.Errorf("info response has no qrid field (len=%d)", len(infoText))
}

func hasQRID(infoText string) bool {
    return regexp.MustCompile(`"?qrid"?\s*[=:]\s*"?([A-Za-z0-9_-]+)`).MatchString(infoText)
}

qr, _, err := plugin.GenerateQRCodeWithSig(...)
if err != nil {
    if strings.Contains(err.Error(), "无法提取qrid") {
        // response shape drift; refetch once before giving up
        return retryOrFail(err)
    }
    return err
}

When it happens

Trigger: generateQRCodeWithSig (called by handleGetStatus, handleRefreshQRCode) successfully extracts api_key but qridRegex.FindStringSubmatch returns fewer than 2 groups on the same infoText.

Common situations: Weibo changed the response format (qrid renamed or nested differently); a partial/error response that still contains api_key but not qrid; response truncated by a proxy or size limit; endpoint serving different content per region or session state.
