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,出现以下错误:
为商品价格,税金和运费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。

我在这里面临一个问题:
[{"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,
类似意味着我遇到了问题(为物品价格,税金和运费指定的金额不等于总金额)。
我编写的代码如下:
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,它无法动态运行。你能查一下代码并帮忙吗?

如果我试图在Android设备上运行此代码,因为点击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。
答案 0 :(得分:5)
为什么要转义此代码中的引号?
[{"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}

我仔细查看了您的代码示例。你能确认totatamount
的来源吗?代码示例代表它将是undefined
,这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 file中有一个很好的代码示例,它提供了如何设置createPaypalButton
的一个很好的示例。如果你还没有,我会建议看看这个。
