我的代码 Sandbox paypal 未来付款出了什么问题？

Question

我已经在我的应用中启用了未来付款权限，并使用开发人员控制面板。但是还没有生效，请查找错误。http://developer.paypal.com/并登录https://developer.paypal.com/developer/accountStatus，您可以查看您拥有的许可证。

 $data = array(
                "intent" => "authorize",
                "payer" => array(
                    "payment_method" => "paypal"
                ),
                "transactions" => array(
                    array("amount" => array(
                        "currency" => "USD",
                        "total" => "1.88"
                    ),
                        "description" => "future of sauces")
                ));

        $data_string = json_encode($data);
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, "https://api.sandbox.paypal.com/v1/payments/payment");
        $headers = array(
            'Content-Type: application/json',
            'PayPal-Client-Metadata-Id: d6743cbb53ea4470a53bfe458f0cb885',
            'Authorization: Bearer A103.B7d5318JDS6NA1zGh02avjCx16oxnBPadUat5z9SlGVGEiOhoAeMuqyz0anGSICS.FAkzECypTS1IXfemHcpVa5yyrGu',
        );
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        //curl_setopt($ch, CURLINFO_HEADER_OUT, true);
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
        $result = curl_exec($ch);
        $information = curl_getinfo($ch);
        curl_close($ch);
        print_r($information);
        die;

在此输出

出于好奇，您是否有使用PayPal SDK的某种厌恶情绪？它可以处理很多事情，并确保一致性。我问这个问题是因为我在请求中没有看到有效的客户端ID和密码 - 我认为这就是你遇到错误的原因。 ID看起来太小了（如果您已经编辑掉了它，请忽略此消息）。 - Nate I

他在请求中使用了一个令牌，只要该令牌没有过期，那么它应该是有效的。 - Matt Cole

如果您还没有阅读此内容，请查看以下链接： https://developer.paypal.com/docs/integration/mobile/make-future-payment/，请查看“获取授权代码”中提到的步骤。 - HardikDG

你在调用时使用了https吗？ - lov2code

由于我没有从任何人那里得到解决方案，所以我逐步深入我的代码并找到了解决方案。

function paypalFuturePayment($userID,$amount)
{
    $amount=number_format($amount,2);
    /* paypal App truxx dev client and secret key*/
    if($userID && $amount){

    $refresh_token = $userData['paypal_refresh_tokens'];
    $Metadata_id = $userData['paypal_metadata_id'];
    if($refresh_token && $Metadata_id){

我制作了一个Paypal模块，希望这份代码能对你有所帮助。

$result_json = json_decode($result);

/* Check if authentication is valid */
if (isset($result_json->access_token))
{
    $enc_data = json_encode($data);

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, 'https://api.sandbox.paypal.com/v1/payments/payment');
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, !in_array($_SERVER['REMOTE_ADDR'], array('127.0.0.1', '::1')));
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 2);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_VERBOSE, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $enc_data);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array(
        'Content-Type: application/json',
        'Authorization: Bearer '.$result_json->access_token,
        'PayPal-Client-Metadata-Id: ************'
    ));

    $result = curl_exec($ch);
    $json_result = json_decode($result);
    curl_close($ch);
}

json_encode($data) 有一些额外的信息，可能对您要执行的交易没有用处，但这只是一个示例。

    "payer": {
        "payment_method": "credit_card",

                    },
                    {
                        "quantity": 1,

                    },
                    {
                        "quantity": 1,
                        "name": "Shipping",
                        "price": 0,
                        "currency": "USD"
                    }
                ],
                "shipping_address": {
                    [...]
                }
            }
        }
    ]
}
