二维码请求返回状态码

Error message

二维码请求返回状态码: %d

What it means

generateQRCodeWithSig in plugin/qqpd checks the HTTP status of the QR-code image endpoint and rejects any non-200 response with the actual status code embedded. It is a guard against serving corrupted/absent QR images to the login flow; callers handleGetStatus and handleRefreshQRCode will surface this to the user as a QR-code fetch failure.

Solutions

1. Check the embedded status code: 403/429 means the client IP is blocked or rate-limited — wait and retry, or use a proxy/rotating exit IP.
2. Retry generateQRCodeWithSig (via handleRefreshQRCode) after a short backoff for transient 5xx codes.
3. Verify the QR-code endpoint URL and that required headers/cookies are still valid (endpoint may have changed server-side).
4. Update the plugin if the upstream API contract changed.

Example fix

// before
resp, err := client.Get(qrURL)
...
// after — retry on transient statuses
for attempt := 0; attempt < 3; attempt++ {
    resp, err := client.Get(qrURL)
    if err == nil {
        if resp.StatusCode == 200 {
            break
        }
        resp.Body.Close()
    }
    time.Sleep(time.Duration(attempt+1) * time.Second)
}

results, err := generateQRCodeWithSig(...)
if err != nil {
    if strings.Contains(err.Error(), "状态码: 429") || strings.Contains(err.Error(), "状态码: 403") {
        time.Sleep(2 * time.Second)
        // retry once, else surface to user as "QR fetch blocked, try later"
    }
}

When it happens

Trigger: The GET request to the QQ PD QR-code endpoint returns a status code other than 200 (e.g. 403 anti-bot block, 429 rate limit, 502/503 upstream outage).

Common situations: Server-side rate limiting after repeated QR refreshes; the QQ endpoint changing or blocking datacenter IPs; transient upstream errors during QR refresh loops.
