react-native-webview使用postMessage后H5不能监听问题（iOS和安卓的兼容问题）

/* 监听rn消息 */
const eventListener = nativeEvent => {//解析数据actionType、extraconst {actionType, extra} = nativeEvent.data && JSON.parse(nativeEvent.data) || {}
}
//安卓用document，ios用window
window.addEventListener('message', eventListener);
document.addEventListener('message', eventListener);

import uaParser from 'ua-parser-js'let timer
let ua = uaParser(navigator.userAgent)const handleWatchRNMessage = () => {if (window.ReactNativeWebView) {window.ReactNativeWebView.postMessage(JSON.stringify({ type: 'getToken' }))}const eventListener = (e) => {console.log('message', e.data)let payload = e.data ? JSON.parse(e.data) : {}let type = payload.typeif (type === 'getToken') {localStorage.setItem('token', payload.token)} else if (type === 'getBrowserInfo') {const { browser } = uawindow.ReactNativeWebView.postMessage(JSON.stringify({ type, browser }))}}if (window.platform === 'rn') {if (ua.os.name === 'iOS') {window.addEventListener('message', eventListener)} else {window.document.addEventListener('message', eventListener)}}
}handleWatchRNMessage()
