【问题描述】：

我想使用包amazon-pay-api-sdk-php 将 Amazon Pay 支付网关添加到我的 Laravel 应用程序中。

根据文档，我编写了这些代码。但是会显示以下错误：

this guide 没有解决我的问题，因为在新版本的包中进行了更改。

控制器方法代码：

public function pay()
{
    $merchant = \'A2NLZCVN7XU3TT\';
    $public_key = \'SANDBOX-AG7E76X2NTPYJUHR2EFGRSTB\';
    $store_id = \'amzn1.application-oa2-client.xxxxxx\';

    $amazonpay_config = array(
        \'public_key_id\' => $public_key,
        \'private_key\'   => base_path(\'amazonpay-private.pem\'),
        \'region\'        => \'eu\',
        \'sandbox\'       => true
    );

    $client = new Client($amazonpay_config);

    $payload = [
        \'storeId\' => $store_id,
        \'webCheckoutDetails\' => [
            \'checkoutReviewReturnUrl\' => route(\'payment.amazonpay\')
        ]
    ];
    $payload = json_encode($payload);

    $signature = $client->generateButtonSignature($payload);

    return view(
        \'front.amazonpay\',
        compact(\'merchant\', \'public_key\', \'payload\', \'signature\'),
    );
}
