钛合金的Paypal集成问题

Question

我必须在我的应用程序中实现Paypal.在这里,我已经将一些产品添加到购物车中.如果我点击购物车,我必须使用Paypal支付金额.

单击Paypal按钮时,我收到以下错误:

为物料价格,税金和运输指定的金额不等于总金额.

为什么会收到此错误？

我使用以下代码:

$.paypalWindow.addEventListener('open', function(){ 
var Paypal = require('ti.paypal'); 
var u = Ti.Android != undefined ? 'dp' : 0; 
var status = Ti.UI.createLabel({ top: 20 + u, height: 50 + u, color: '#333', text: 'Loading, please wait...' }); 
$.paypalWindow.add(status); var price = totalamount; 
 var   invoiceitemslist = JSON.stringify(data);

var button; function addButtonToWindow() {
if (button) { $.paypalWindow.remove(button); button = null; } 
button = Paypal.createPaypalButton({ width: 194 + u, height: 37 + u,    buttonStyle: Paypal.BUTTON_194x37, top: 20 + u,

    language: 'en_US',
    appID: 'APP-80W284485P519543T',
    paypalEnvironment: Paypal.PAYPAL_ENV_SANDBOX, 
    feePaidByReceiver: false,
    enableShipping: false,
    payment: { 
        paymentType: Paypal.PAYMENT_TYPE_BUSINESS,
        subtotal: price, 
        tax: 0.00,
        shipping: 0.00,
        currency: 'USD',
        recipient: 'thaibusiness@gmail.com',
        customID: 'anythingYouWant',
        invoiceItems:
    [{"name":"Bajaj 200 mm Ultima PT01 Personal Fan","totalPrice":2997,"itemPrice":999,"itemCount":3},
          ],
        ipnUrl: 'http://www.appcelerator.com/',
        merchantName: 'EYMOBINS Insurance',
        memo: 'For the insurance with EYMOBINS!'
          }
        });

button.addEventListener('paymentCancelled', function (e) {
    alert('Payment cancelled. Please try again!');
    addButtonToWindow();
});
button.addEventListener('paymentSuccess', function (e) {
    alert('Payment successfull. Please get your Policy No.!'+"  "+e.transactionID);
    $.paypalWindow.remove(button);
    //addButtonToWindow();
});
button.addEventListener('paymentError', function (e) {
    alert('Payment Error. Please try again!');
    addButtonToWindow();
});

button.addEventListener('buttonDisplayed', function () {
    $.paypalWindow.remove(status);
    //alert('Please pay '+Ti.App.totalcost+'$ with Paypal!')
});

button.addEventListener('buttonError', function () {

});

 $.paypalWindow.add(button);
 } 
 addButtonToWindow();            
  });


 $.paypalWindow.open();

请检查代码并给我一个解决上述问题的想法.

在这里,我面临一个问题:

[{"name":"Bajaj 200 mm Ultima PT01 Personal Fan","totalPrice":999,"itemPrice":999,"itemCount":1},{"name":"Average2Excellent CBSE KG EVS MATHS ENG Educational CD ROMS","totalPrice":547,"itemPrice":547,"itemCount":1}]

这里的totalamount是1546.这里我在控制台中打印了invoiceitems,我得到的数据如上所述.

所以我已经给出了:

invoiceItems:invoiceitems,

就像我收到问题的意思一样(为物品价格,税收和运输指定的金额不等于总金额).

同样的事情我写的代码如下:

invoiceItems:[{"name":"Bajaj 200 mm Ultima PT01 Personal Fan","totalPrice":999,"itemPrice":999,"itemCount":1},{"name":"Average2Excellent CBSE KG EVS MATHS ENG Educational CD ROMS","totalPrice":547,"itemPrice":547,"itemCount":1}]

它工作得很好.

分配值时,它不会动态工作.你能检查一下代码并提供帮助吗？

如果我试图在Android设备上运行此代码,因为我点击paypal按钮没有任何事情发生.为什么登录表单未在Android设备中打开.

Answer 1

你为什么要逃避这段代码中的引号？

[{"name":"Bajaj 200 mm Ultima PT01 Personal Fan","totalPrice":2997,"itemPrice":999,"itemCount":3}

这不是有效的JSON(或Javascript).这需要Paypal吗？我认为它应该是这样的:

[{"name":"Bajaj 200 mm Ultima PT01 Personal Fan","totalPrice":2997,"itemPrice":999,"itemCount":3}

我仔细看了一下你的代码示例.你能确认一下totatamount来自哪里吗？正如代码示例所示undefined,它将与您描述的错误消息一致.在提交此数据之前,您能否立即确认它肯定是正确的值？

ti.paypal规范在README文件中有一个很好的代码示例,它给出了如何设置的一个很好的例子createPaypalButton.如果你还没有,我会建议看看这个.

button = Paypal.createPaypalButton({
    // NOTE: height/width only determine the size of the view that the button is embedded in - the actual button size
    // is determined by the buttonStyle property!
    width: 194 + u, height: 37 + u,
    buttonStyle: Paypal.BUTTON_194x37, // The style & size of the button
    bottom: 50 + u,

    language: 'en_US',
    textStyle: Paypal.PAYPAL_TEXT_DONATE, // Causes the button's text to change from "Pay" to "Donate"

    appID: '<<<YOUR APP ID HERE>>>', // The appID issued by Paypal for your application; for testing, feel free to delete this property entirely.
    paypalEnvironment: Paypal.PAYPAL_ENV_SANDBOX, // Sandbox, None or Live

    feePaidByReceiver: false, // This will only be applied when the transaction type is Personal
    enableShipping: false, // Whether or not to select/send shipping information

    advancedPayment: { // The payment itself
        payments: [
            {
                isPrimary: true, // Mark this as the primary vendor; this marks this as a chain payment.
                merchantName: 'Primary Vendor',
                paymentType: Paypal.PAYMENT_TYPE_SERVICE, // The type of payment
