下载微信账单问题

[yqsphp]

通过加载插件请求对账单
`/申请交易账单
$plugin = Pay::wechat()->mergeCommonPlugins([GetTradeBillPlugin::class]);
//$plugin = Pay::wechat()->mergeCommonPlugins([DownloadBillPlugin::class]);

    $params = [
        'bill_date' => $date,
        'bill_type' => 'ALL',
    ];
    $result = Pay::wechat()->pay($plugin, $params);`

返回下载地址后，在调用插件
`$plugin = Pay::wechat()->mergeCommonPlugins([DownloadBillPlugin::class]);

    $params = [
        'download_url' => $result->download_url,
        //'sign' => $result->hash_value
    ];
    $bill = Pay::wechat()->pay($plugin, $params);

[5003] InvalidResponseException in Functions.php line 204
$random = $message->getHeaderLine('Wechatpay-Nonce');
$sign = $message->getHeaderLine('Wechatpay-Signature');
$body = (string) $message->getBody();
dump($sign);

    $content = $timestamp."\n".$random."\n".$body."\n";
    $public = get_wechat_config($params)['wechat_public_cert_path'][$wechatSerial] ?? null;

    if (empty($sign)) {
        throw new InvalidResponseException(Exception::INVALID_RESPONSE_SIGN, '', ['headers' => $message->getHeaders(), 'body' => $body]);
    }

`
异常，签名空，不知道是不是这么调用

别验证签名。

Pay::wechat()->pay([
PreparePlugin::class,
DownloadBillPlugin::class,
RadarSignPlugin::class,
ParserPlugin::class,
], $params);
