Get QrCode Error: ${JSON.stringify(result)}

Error message

Get QrCode Error: ${JSON.stringify(result)}

What it means

The aliyun.jsx qrcode() helper requests a login QR code from Alipan's OAuth endpoint (https://openapi.alipan.com/oauth/authorize/qrcode). When the HTTP response is not ok and the error body contains no `message` field, the code falls back to throwing `Get QrCode Error: <raw body JSON>`. It means the QR-code request failed with an unexpected response shape (no usable error message returned by the API).

Solutions

  1. Retry the QR-code request; transient gateway errors usually resolve on retry.
  2. Inspect the JSON in the error message to identify the actual failure (status code, blocked request, etc.).
  3. Check network/proxy settings — the Tauri HTTP client must be able to reach openapi.alipan.com.
  4. Verify the Alipan OAuth API still returns errors with a `message` field; update the parser if the API contract changed.

Example fix

// before
throw new Error(`Get QrCode Error: ${JSON.stringify(result)}`);
// after
if (res.status === 429 || res.status >= 500) {
    // retry with backoff before giving up
    return retryQrcode();
}
throw new Error(`Get QrCode Error (HTTP ${res.status}): ${JSON.stringify(result)}`);
Defensive patterns

Strategy: try-catch

Validate before calling

// before calling qrcode(), verify connectivity to the API
const reachable = await fetch('https://openapi.alipan.com').then(r => true).catch(() => false);
if (!reachable) throw new Error('openapi.alipan.com unreachable — check network/proxy');

Type guard

function isQrCodeResponse(r) {
  return r && typeof r === 'object' && typeof r.qrCodeUrl === 'string' && typeof r.sid === 'string';
}

Try / catch

try {
  const { url, sid } = await qrcode();
  showQr(url);
} catch (e) {
  if (String(e.message).startsWith('Get QrCode Error')) {
    // non-2xx without API message: transient/gateway — retry with backoff
    await sleep(2000);
    retryQrcode();
  } else {
    showError(e.message);
  }
}

Prevention

When it happens

Trigger: Calling qrcode() and the POST to openapi.alipan.com/oauth/authorize/qrcode returns a non-2xx status whose res.data lacks a `message` key (e.g. HTML error page, empty body, proxy/gateway error JSON with different field names).

Common situations: Alipan API downtime or rate limiting returning an HTML/CDN error page; a corporate proxy or firewall intercepting the request; the hardcoded client_id being revoked or the API contract changing; DNS/network failure inside the Tauri HTTP client producing an opaque error payload.
