【中文标题】react-native-webview 如何注入 javascript？【英文标题】：react-native-webview how to inject javascript? 【发布时间】：2020-10-05 04:55:31 【问题描述】：

在 android 上，我一直在使用 expo-stripe-checkout 在 Expo 托管应用上进行付款。在我更新到最新版本的 expo 和 react-native 之前，一切都运行良好。现在，没有一个回调，如 onClose 和 onPaymentSuccess 正在工作。似乎 WebView 已从 react-native 中删除，所以我直接从 react-native-webview 导入。

我没有使用expo-stripe-checkout，而是创建了自己的组件，以尝试解决正在发生的事情，似乎WebView 的injectedjavascript 根本没有运行，因此window.postMessage 或window.ReactNativeWebView.postMessage 没有运行不工作。

我尝试了网络上的几种不同建议，但没有任何效果：

StripeCheckout.js

import React,  Component  from 'react';
import  Platform, View, ViewPropTypes  from 'react-native';
import  PropTypes  from 'prop-types';
import  WebView  from 'react-native-webview'

class StripeCheckout extends Component 

  render() 
    const 
      publicKey,
      amount,
      allowRememberMe,
      currency,
      description,
      imageUrl,
      storeName,
      prepopulatedEmail,
      style,
      onPaymentSuccess,
      onClose
     = this.props;

    const jsCode = `(function() 
                    console.log('hello')
                    var originalPostMessage = window.ReactNativeWebView.postMessage;
                    var patchedPostMessage = function(message, targetOrigin, transfer) 
                      originalPostMessage(message, targetOrigin, transfer);
                    ;
                    patchedPostMessage.toString = function() 
                      return String(Object.hasOwnProperty).replace('hasOwnProperty', 'postMessage');
                    ;
                    window.ReactNativeWebView.postMessage = patchedPostMessage;
                  )();`;
    const runFirst = `
      console.log('firstRun')
      window.isNativeApp = true;
      true; // note: this is required, or you'll sometimes get silent failures
    `;

    return (
      <WebView
        ref=(ref) =>  this.webview = ref; 
        javaScriptEnabled=true
        injectedJavaScriptForMainFrameOnly=false
        scrollEnabled=false
        bounces=false
        messagingEnabled=true
        onMessage=(event) => console.log(event)
        onPaymentSuccess(event.nativeEvent.data)
        injectedJavaScriptBeforeContentLoaded=runFirst
        injectedJavaScript=jsCode
        source= html: `<script src="https://checkout.stripe.com/checkout.js"></script>
            <script>
            var handler = StripeCheckout.configure(
              key: '$publicKey',
              image: '$imageUrl',
              locale: 'auto',
              token: function(token) 
                window.ReactNativeWebView.postMessage(token.id, token.id);
              ,
            );
            window.onload = function() 
              console.log('onload')
              handler.open(
                image: '$imageUrl',
                name: '$storeName',
                description: '$description',
                amount: $amount,
                currency: '$currency',
                allowRememberMe: $allowRememberMe,
                email: '$prepopulatedEmail',
                closed: function() 
                  window.ReactNativeWebView.postMessage("WINDOW_CLOSED", "*");
                
              );
            ;
            </script>`
        style=[ flex: 1 , style]
        scalesPageToFit=Platform.OS === 'android'
      />
    );
  


StripeCheckout.propTypes = 
  publicKey: PropTypes.string.isRequired,
  amount: PropTypes.number.isRequired,
  imageUrl: PropTypes.string.isRequired,
  storeName: PropTypes.string.isRequired,
  description: PropTypes.string.isRequired,
  allowRememberMe: PropTypes.bool.isRequired,
  onPaymentSuccess: PropTypes.func.isRequired,
  onClose: PropTypes.func.isRequired,
  currency: PropTypes.string,
  prepopulatedEmail: PropTypes.string,
  style: ViewPropTypes.object
;

StripeCheckout.defaultProps = 
  prepopulatedEmail: '',
  currency: 'USD',
;

export default StripeCheckout;

没有控制台记录。条带集成弹出并成功返回一个令牌，但没有任何反应，并且组件没有接收到令牌（我可以看到它正在从条带日志中返回一个令牌）。

如果还有什么我应该发布的，请告诉我。谢谢！
