查询微信扫码状态失败：HTTP {status}

Error message

查询微信扫码状态失败：HTTP {status}

What it means

poll_qr_status GETs the QR status endpoint with the qr_code string; request timeouts are deliberately tolerated and reported as status wait, so this error means the gateway answered with a real HTTP error status and the polling iteration aborts.

Solutions

1. Fetch a fresh QR code when the current one is stale or polling keeps failing
2. Use the same base_url and route headers as the original fetch_qr_code call
3. Retry with backoff for 5xx and inspect the body for 4xx cause

let st = match WeixinClient::poll_qr_status(&base, &tag, &qr.qr_code).await {
    Ok(st) => st,
    Err(e) if e.to_string().contains("HTTP ") => {
        let qr = WeixinClient::fetch_qr_code(&base, &tag).await?; // stale code, refresh
        WeixinClient::poll_qr_status(&base, &tag, &qr.qr_code).await?
    }
    Err(e) => return Err(e),
};

When it happens

Trigger: Polling with an expired or invalid qrcode value (4xx); gateway 5xx; base_url or route header mismatches versus the ones used to fetch the code.

Common situations: QR code expired server-side while polling continues; IP rate-limited; endpoint changed after a gateway update.
