paypal结帐按钮在javascript中获取json响应

Question

在paypal API reference page 中，它说创建付款后会返回响应。我想在支付完成后使用交易信息，但是不知道如何从基础集成场景here获取这个响应json。浏览完文档后，我看不到在哪里可以获得此响应。我在这里错过了一个选项吗？提前致谢。

以下是我的代码

paypal.Button.render({

    // Set your environment

    env: 'sandbox', // sandbox | production

    // Pass the client ids to use to create your transaction on sandbox and production environments

    client: {
        sandbox:    'removed for security', // from https://developer.paypal.com/developer/applications/
        production: 'removed for security'  // from https://developer.paypal.com/developer/applications/
    },

    // Pass the payment details for your transaction
    // See https://developer.paypal.com/docs/api/payments/#payment_create for the expected json parameters

    payment: function() {
        return paypal.rest.payment.create(this.props.env, this.props.client, {
            transactions: [
                {
                    amount: {
                        total:    total,
                        currency: 'USD'
                    },
                    custom: purchaseOrderNumber
                }
            ]
        });
    },

    // Display a "Pay Now" button rather than a "Continue" button

    commit: true,

    // Pass a function to be called when the customer completes the payment

    onAuthorize: function(data, actions) {
        console.log("data", data);
        console.log("actions", actions);
        return actions.payment.execute().then(function() {
            console.log('The payment was completed!');

            //use transaction information from json response here
        });
    },

    // Pass a function to be called when the customer cancels the payment

    onCancel: function(data) {
        console.log('The payment was cancelled!');
    }

}, '#paypal-button');

数据的控制台结果

{

"paymentToken":"EC-8T213183GM917341N",
"payerID":"784ARKSZGWBPG",
"paymentID":"PAY-00M809553A479072XLEBN4RI",
"intent":"sale",
"returnUrl":"https://www.sandbox.paypal.com/?paymentId=PAY-00M809553A479072XLEBN4RI&token=EC-8T213183GM917341N&PayerID=784ARKSZGWBPG"

}

操作结果的控制台

{
    "payment":{}
}
//see below for console screenshot

EDIT2：

对paypal框架的请求和响应

看起来最后一张图片是我真正需要的响应。有没有办法从基本的 paypal 按钮获取这些数据？

给actions.payment.execute().then()添加一个参数来捕捉响应

paypal.Button.render({

    // Set your environment

    env: 'sandbox', // sandbox | production

    // Pass the client ids to use to create your transaction on sandbox and production environments

    client: {
        sandbox:    'removed for security', // from https://developer.paypal.com/developer/applications/
        production: 'removed for security'  // from https://developer.paypal.com/developer/applications/
    },

    // Pass the payment details for your transaction
    // See https://developer.paypal.com/docs/api/payments/#payment_create for the expected json parameters

    payment: function() {
        return paypal.rest.payment.create(this.props.env, this.props.client, {
            transactions: [
                {
                    amount: {
                        total:    total,
                        currency: 'USD'
                    },
                    custom: purchaseOrderNumber
                }
            ]
        });
    },

    // Display a "Pay Now" button rather than a "Continue" button

    commit: true,

    // Pass a function to be called when the customer completes the payment

    onAuthorize: function(data, actions) {

        return actions.payment.execute().then(function(param) {
            console.log('The payment was completed!');

            //param is the json response
        });
    },

    // Pass a function to be called when the customer cancels the payment

    onCancel: function(data) {
        console.log('The payment was cancelled!');
    }

}, '#paypal-button');

设置看起来一切都很好，您现在所需要的只是决定您想要什么以及如何处理您的响应。

在 onAuthorize 函数中，您可以对所有已批准的销售执行类似 (github paypal checkout button) 的操作（检查 data.status 是否为 approved（信用卡）或 created（使用贝宝付款） ), 那么你应该有一个data.payer 包含所有信息）：

jQuery.post('/my-api/execute-payment', { paymentID: data.paymentID, payerID: data.payerID });
            .done(function(data) { /* Go to a success page */ })
            .fail(function(err)  { /* Go to an error page  */  });

或者直接在函数中使用datajson对象。
