Paypal 与 Ionic 3 的集成

Question

我正在使用 ionic 原生插件进行 PayPal 支付：https://ionicframework.com/docs/native/paypal/

我的代码是：

this.payPal.init({   PayPalEnvironmentProduction: 'XXXXXXXXXXX',  
PayPalEnvironmentSandbox: 'XXXXXXXXXXXXX' }).then(() => {  
   this.payPal.prepareToRender('PayPalEnvironmentSandbox', new
   PayPalConfiguration({   })).then(() => {
   let payment = new PayPalPayment('3.33', 'USD', 'Description', 'sale');
   this.payPal.renderSinglePaymentUI(payment).then(() => {}, () => {
});   
}, () => {}, 
() => {});

出现错误无法解析 PayPalPayment 的所有参数：(?, ?, ?, ?, ?)。

您必须将整个代码包装在一个函数中，并在需要调用时调用它。 首先，您需要为测试目的创建沙箱 ID。然后通过创建沙箱 ID，您将需要创建一个应用程序，您将从中获取客户端 ID。然后将您的客户 ID 插入 PayPalEnvironmentSandbox。

paypalPayment(){
    this.payPal.init({
      PayPalEnvironmentProduction: 'xxxxxxxxxxxx',
      PayPalEnvironmentSandbox: 'xxxxxxxxxxxxxx'
    }).then(() => {

      this.payPal.prepareToRender('PayPalEnvironmentSandbox', new PayPalConfiguration({

      })).then(() => {
        let payment = new PayPalPayment('3.33', 'USD', 'Description', 'sale');
        this.payPal.renderSinglePaymentUI(payment).then((success) => {
          console.log(success);
        }, () => {
          // Error or render dialog closed without being successful
          console.log('error paypal')
        });
      }, () => {
        // Error in configuration
        console.log('error configuration paypal')
      });
    }, () => {
      // Error in initialization, maybe PayPal isn't supported or something else
      console.log('error last paypal')
    });
  }
