微信企业付款到零钱突然升级商家转账到零钱，有没有已经对接了的~

五月中旬的时候还看到微信企业付款到零钱，连续支付了一个月，突然发现微信企业付款不见了，于是打了客服电话，客服说五月中下旬升级为商家转账到零钱。网上文档很少，官方文档

一直都是用easywechat
有没有支持商家转账到零钱的包~
推荐一下

用了wechatpay-php出现报错

       // 商户号
        $merchantId = env('WXAPP_MCH_ID');

// 从本地文件中加载「商户API私钥」，「商户API私钥」会用来生成请求的签名
        $merchantPrivateKeyFilePath = file_get_contents(base_path(env('WXAPP_KEY_PATH')));
        $merchantPrivateKeyInstance = Rsa::from($merchantPrivateKeyFilePath, Rsa::KEY_TYPE_PRIVATE);

// 「商户API证书」的「证书序列号」
        $merchantCertificateSerial = '4D15C9C132BDA318198D27E7797753AE5B07AF09';

// 从本地文件中加载「微信支付平台证书」，用来验证微信支付应答的签名
        $platformCertificateFilePath = file_get_contents(base_path(env('WXAPP_CERT_PATH')));
        $platformPublicKeyInstance = Rsa::from($platformCertificateFilePath, Rsa::KEY_TYPE_PUBLIC);

// 从「微信支付平台证书」中获取「证书序列号」
        $platformCertificateSerial = PemUtil::parseCertificateSerialNo($platformCertificateFilePath);

// 构造一个 APIv3 客户端实例
        $instance = Builder::factory([
            'mchid' => $merchantId,
            'serial' => $merchantCertificateSerial,
            'privateKey' => $merchantPrivateKeyInstance,
            'certs' => [
                $platformCertificateSerial => $platformPublicKeyInstance,
            ],
        ]);

// 发送请求
        $resp = $instance->chain('v3/certificates')->get(
            ['debug' => true] // 调试模式，https://docs.guzzlephp.org/en/stable/request-options.html#debug
        );
        echo $resp->getBody(), PHP_EOL;

The `certs()` contains the merchant's certificate serial number() which is not allowed here.

感谢 微信v3支付-WeChatPay\Exception\InvalidArgumentExcept ？

        $obj = new AesUtil('v3 key');

        $str = openssl_x509_parse(file_get_contents(base_path(env('WXAPP_CERT_PATH'))));

        $merchant_id = env('WXAPP_MCH_ID');//商户号
        $serial_no = $str['serialNumberHex'];//API证书序列号
        $sign = $this->get_Sign("https://api.mch.weixin.qq.com/v3/certificates", "GET", "", $this->get_Privatekey(), $merchant_id, $serial_no);//$http_method要大写

//        dd($result);//解密后的内容，就是证书内容
        dump($aa);  //证书

以上证书替换

某种情况下巨坑

 $resp = $instance->chain("v3/transfer/batches/out-batch-no/{$out_batch_no}/details/out-detail-no/{$out_detail_no}")->get();
return $resp->getBody()

返回结果

GuzzleHttp\Psr7\Stream^ {#1209
  -stream: stream resource {@685
    wrapper_type: "PHP"
    stream_type: "TEMP"
    mode: "w+b"

    options: []
  }
  -size: null

解决
