Cordova Paypal和ionic 2不工作，出现JSON错误

我不知道为什么我不能将Ionic2应用程序与Paypal集成

我正在为PayPal cordova mobile sdk使用Ionic native包装器

我在

Paypal.init

中获得了成功，但在

renderSinglePaymentUI

import { Injectable } from '@angular/core';
//import { Paypal, PaypalPayments } from 'ionic-native';

import {PayPal, PayPalPayment, PayPalPaymentDetails, PayPalConfiguration, PayPalConfigurationOptions} from 'ionic-native';
//import {PayPal} from 'ionic-native';

@Injectable()
export class Payments {

paymentdata : PayPalPayment;
paymentdetails: PayPalPaymentDetails;
paypalConfig: PayPalConfiguration;
paypalConfigOptions: PayPalConfigurationOptions;

constructor() {
 this.initiatePaypal();   
}

initiatePaypal(){
   // this.paypalConfig = new PayPalConfiguration("ssn.bala@gmail.com","+65", "85256592", "MMS", "mmssingapore.org","mmssingapore.org",YES,0,YES,"en",YES,NO,YES,"ssn.bala-buyer@gmail.com", "testing123" );

PayPal.init({
        "PayPalEnvironmentProduction": "YOUR_PRODUCTION_CLIENT_ID",
        "PayPalEnvironmentSandbox": "AYghcu8pISVBO03yX58CVC7vccATg5jraW-k52jPw9V63RQkuIaS2H8moi2OnWln97FPvP-gDEMbMlHj"
        })
    .then(onSuccess => {
        console.log("init success");
        alert("init success" + JSON.stringify(onSuccess));
    })
    .catch(onError => {
        console.log("init failed", Error);
        alert("init failed" + JSON.stringify(onError));
    });
}


initiatePayment(){

    this.paymentdetails = new PayPalPaymentDetails("10.00", "0", "hello");
    this.paymentdata = new PayPalPayment("10.00","USD", "MMS tickets", "sale");


    PayPal.renderSinglePaymentUI(this.paymentdata)
    .then(onSuccess => {
         console.log('OnSuccess Render: ' + JSON.stringify(onSuccess));
         alert('OnSuccess Render: ' + JSON.stringify(onSuccess));
       })
    .catch(onError=> {
       console.log('onError Render: ' + JSON.stringify(onError));
       alert('onError Render: ' + JSON.stringify(onError));
         });
}



}

我使用的是离子2 RC0

今天我试着一起使用爱奥尼亚2和贝宝。我按照办公室的指示做了，几乎所有的事情都成功了，但也有一些小的例外。这里有一个简单的提供者，它工作得很好。希望有帮助在付款之前，应该调用“preload”，当然这只是一个示例代码

import { Injectable } from '@angular/core';
import { PayPal, PayPalPayment, PayPalConfiguration } from '@ionic-native/paypal';

@Injectable()
export class PaypalProvider {    
    private paypal: PayPal;

    constructor() { }

    public preload() {
        this.paypal = new PayPal();

        this.paypal.init({
            PayPalEnvironmentProduction: "YOUR_PRODUCTION_CLIENT_ID",
            PayPalEnvironmentSandbox: "YOUR_SANDBOX_CLIENT_ID"
        }).then(value => {
            console.log('[???] init:', value);
            this.paypal.prepareToRender('PayPalEnvironmentSandbox', new PayPalConfiguration({
                presentingInPopover: true,
            })).then(value => {
                console.log('[???] prepared:', value);
            }).catch(error => {
                console.log('[???] Error:', error);
            });
        }).catch(error => {
            console.log('[???] Error:', error);
        });
    }

    public fooPayment() {
        let payment = new PayPalPayment('10.00', 'BRL', 'Some Product', 'Assinatura');
        this.paypal.renderSinglePaymentUI(payment).then(value => {
            console.log('[???] Payment:', value);
        }).catch(error => {
            console.log('[???] Payment Error', error);
        });
    }    
} // - - -
