我有一个具有实时聊天支持(使用内部通信)的Android React Native应用程序。要访问对讲机,我将WebViewinjectedJavaScript一起使用以显示UI。它在我的开发版本上正常工作,但是当我进行发行版本时,它抱怨找不到window.Intercom(如果删除window.,我会遇到相同的相对问题)

这是我要运行的代码

IntercomContainer.js

// =============================================================================
// Components >> IntercomContainer
// =============================================================================
// @flow

// Import
// =============================================================================

import * as React from 'react';
import { View, WebView } from 'react-native';
import Spinner from 'react-native-loading-spinner-overlay';

import styles from './styles';

// Content
// =============================================================================

type State = {
    isLoading: boolean,
};

type Props = {
    appId: string,
}

// Render
// =============================================================================

export default class IntercomContainer extends React.Component<Props, State> {

    props: Props = {
        appId: '',
    };

    state: State = {
        isLoading: true,
    }

    setState: Function;

    injectedJS = (appId: string) => {
        return `
            try {

                window.Intercom('boot', {
                    app_id: '${appId}',
                });

                window.Intercom('show');
                window.Intercom('onShow', function() {
                    document.getElementById('message').innerHTML = '';
                    setTimeout(() => {
                        document.getElementById('message').innerHTML = 'Click on the chat button in the bottom-right to open chat...';
                    }, 1000)
                });

            } catch(e) {
                alert('Intercom failed to load: ' + e.message);
            }
        `;
    }

    onLoadEnd = () => {
        this.setState({
            isLoading: false,
        });
    }

    render(){
        const { appId } = this.props;
        const { isLoading } = this.state;

        return (
            <View style={styles.container}>
                <Spinner visible={isLoading} />
                <WebView
                    injectedJavaScript={this.injectedJS(appId)}
                    source={require('./IntercomWebView.html')}
                    onLoadEnd={this.onLoadEnd}
                    javaScriptEnabled={true}
                    style={styles.webView}
                />
            </View>
        );
    }
}

谢谢!

最佳答案

您问题的根本原因很可能与postMessage错误相同。使用Intercom对象的代码将在初始化该对象的JavaScript代码之前加载。作为一种解决方法,您可以使用一些神奇的值在setTimeout中调用此代码,或者实现more "neat" solution,在该方法中,您将延迟对Intercom对象的实际调用,直到对其进行初始化为止
