Question

我的目标是使用＆＃34; paypal＆＃34;设置定期的6个月和12个月订阅。作为我们SaaS的付款方式。我使用其余的API，我无法找到的一件事就是如何进行一次性销售，并使用PayPal的其余部分将我的代码重新定为定期付款API（我现在已经阅读过了）。我们在这里：

我有一个工作advanced server integration用于使用Paypal的Express Checkout REST API进行付款。

我按照上面链接中解释的代码示例创建了一次性销售，以及来自paypal的this example中显示的内容。我已经尝试将两步流程切换为包含计费协议创建和执行调用，但是打开用户登录到paypal的轻窗口正在停止显示错误消息＆＃34; Things此刻似乎没有工作。请稍后再试＃34;这是我的javascript代码，几乎与工作示例完全相同，但路径不同。

paypal.Button.render({

    // Set your environment

    env: 'sandbox', // sandbox | production

    // Wait for the PayPal button to be clicked
    payment: function(resolve, reject) {

    // Make a call to the merchant server to set up the payment
        console.log("button clicked")
        return paypal.request.post('/payment/paypal/subscription', {amount: '0.02'})
            .then(function(res) {
                resolve(res.payToken); #--WHERE I'M GOING WRONG
            })
            .catch(function(err) { reject(err); });
    },

    // Wait for the payment to be authorized by the customer
    onAuthorize: function(data) {

        // Make a call to the merchant server to execute the payment
        return paypal.request.post('/payment/paypal/execute', {
            data: data,
            paymentID: data.paymentID,
            payerID: data.payerID
        }).then(function (res) {
            if (res.state == "active") {
                document.querySelector('#paypal-button-container-server').innerText = 'Payment Complete!';
            } else {
                console.log(res);
                alert("Payment could not be approved, please try again.")
            }
        });
    }

}, '#paypal-button-container-server');

我可以说我在付款功能中出错了，就是在resolve(res.payToken)的行上。我不知道我应该传递给这个函数的v1 / payments / billing-agreement响应中的哪些数据，但是已经尝试了profile_id和approval_url（实际的href） - ＆＃34; href＆＃34;：＆＃34; https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXX＆＃34;）。

我哪里错了？如果这是可能的，我觉得我只是一个工作的例子，而不是做这项工作，但我想知道它是否能够像我做的那样（在哪种情况可能需要通过Payflow来完成？）。

注意：我完全理解结算协议和结算资料，而我的问题不在于REST API。除了工作的一次性销售实施，我还可以制作所有必要的账单资料/协议（通过邮递员验证）。

以下是v1/payments/billing-agreements沙箱调用的响应，如果有人可以在其中指出正确的数据。

Answer 1

REST API仍会传回快速结帐网址，但为了将其与checkout.js前端集成一起使用，您需要传回在审批网址中找到的令牌。您可以解析此URL并获取服务器上的令牌部分，并在调用resolve方法之前将其返回或传递。

即

approval_url = { 
    "href": "https://www.sandbox.paypal.com/cgi-bin/webscr?cmd=_express-checkout&token=EC-XXXXXXXXXXXXX" 
}

var token = "EC-XXXXXXXXXXXXX";
resolve(token);
