问题描述
我正在使用 expo-payments-stripe 和 expo 制作应用程序。我创建了一个对象,以便将参数传递给函数 Stripe.createtokenWithCardAsync(params)。但是,console.log(params) 显示了我想发送给函数的所有内容,但是从函数返回的令牌没有我传递的所有参数。
这是我的代码:
import React from 'react';
import {StyleSheet,Text,TouchableOpacity,View,TouchableHighlight } from 'react-native';
import { CreditCardInput } from 'react-native-credit-card-input';
import {Paymentsstripe as Stripe} from 'expo-payments-stripe';
export default class TarjetaScreen extends React.Component {
constructor(props){
super(props)
this.state = {
data: {},//JSON vacío
bolTarjeta: false
}
}
// Metodo que se va a ejecutar cada vez que el usuario rellene un campo del formulario y pasa en formData los valores en un JSON.
onChange = (formData) => {
this.setState({data: formData.values,//Metemos en data el JSON de los valores insertados.
bolTarjeta: formData.valid}) //Sera true cuando el usuario retorne todos los campos y sean válidos.
}
onFocus = (field) => console.log("focus",field) //Se va a ejecutar cada vez que el usuario pinche en un textinput.
async componentDidMount () {
Stripe.setoptionsAsync({
publishableKey: 'pk_test_51IkSMjAwYEmxhVRRPOaKFC3ORP9KNS1PymGMGdoer0InVFq0HbDaa2VLAas9UdjJvM1LIsKKsrLFhicEtfq5wrtm00oaDwyGJ8'
})
}
pagar = async () => {
const params = {
number: this.state.data.number,expMonth: parseInt(this.state.data.expiry.substring(0,2)),expYear: parseInt(this.state.data.expiry.substring(3,5)),cvc: this.state.data.cvc
}
console.log(params.number)
const token = await Stripe.createtokenWithCardAsync(params)
console.log(token)
const source = await Stripe.createSourceWithParamsAsync({ type: 'card',amount: this.props.money,currency: 'EUR'})
console.log(source)
}
render() {
return (
<View style={{ flex:1,alignItems: 'center'}}>
<View style={{ width: '100%',height: '30%',marginTop: 60}}>
<CreditCardInput
autofocus
requiresName
requiresCVC
cardScale={0.9}
validColor={'black'}
invalidColor={'red'}
placeholderColor={'darkgray'}
placeholders={{number: "1234 5678 1234 5678",name: "NOMBRE COMPLeto",expiry: "MM/YY",cvc:"CVC"}}
labels={{number: "NÚMERO TARJETA",expiry: "EXPIRA",cvc: "CVC/CCV"}} //Lo pongo en español,por defecto vienen en inglés
onFocus={this.onFocus}
onChange={this.onChange}
/>
</View>
<View style={{
width: 280,marginTop: 150,marginBottom: 20,backgroundColor: '#B71C1C',borderRadius: 60,}}>
<TouchableOpacity onPress={()=>this.pagar()}>
<Text style={{
textAlign: 'center',fontSize: 17,color: 'white',paddingVertical: 15
}}>Pagar</Text>
</TouchableOpacity>
</View>
</View>
)
}
}
console.log(params) 打印:对象 { "cvc": "424","expMonth": 10,"expYear": 24,“号码”:“4242 4242 4242 4242”, }
console.log(token) 打印:对象 { “卡片”:对象{ “地址城市”:空, “地址国家”:空, “addressLine1”:空, “addressLine2”:空, “地址状态”:空, “地址邮编”:空, "brand": "签证","cardId": "card_1IlPKLAwYEmxhVRRJwEXUo5G","国家": "美国",“货币”:空, “CVC”:空, "expMonth": 10,"expYear": 2024,“指纹”:空, "资金": "信用","last4": "4242",“名称”:空, “数字”:空, },“创建”:1619662205000, “实时模式”:假, "tokenId": "tok_1IlPKLAwYEmxhVRRFmbUbymd",“使用”:假, }
解决方法
您永远不会从 Stripe 获得完整的卡号或 CVC,因为这些都是敏感数据。
更一般地说,您应该在此处使用 Elements,以免将您的应用程序暴露给原始卡详细信息:https://stripe.com/docs/stripe-js/react
,我已经使用 stripe-client 解决了这个问题。
