前端 JavaScript 与鸿蒙 Web 组件间相互通信的方式;
注:此案例采用两端间双向模式机制进行通信;
单向模式可参考 前端 Web 与原生应用端 WebView 通信交互
官方文档传送门如下:
WebCallApp
AppCallWeb
一.鸿蒙端
1.设置 WebCallApp 方法
import WebView from '@ohos.web.webview';
import business_error from '@ohos.base'
import { BusinessError } from '@kit.BasicServicesKit';
// 声明注册对象
@State WebCallAppMethod: WebCallAppClass = new WebCallAppClass(this.controller)
// WebCallApp 类方法
class WebCallAppClass {
private webView: WebView.WebviewController;
constructor(webView: WebviewController) {
this.webView = webView
}
// 方式一: 方法无回调,通过交互协议 WebCallApp => AppCallWeb
WebCallApp(value: string) {
console.log('********* [交互] --- 协议 - HWebView')
// 接收 Web 端数据源
console.log(value)
// 交互数据处理
do something ...
// 如果需要数据回调,则通过如下 callback 方法将处理后的数据回调至 Web
// 如果不需要数据回调,则执行其它业务逻辑即可,无需调用如下 callback 方法
this.webView.runJavaScript(value)
}
// 方式二: 方法回调,WebCallApp 直接 return
// WebCallApp(value: string): string { // 直接 return 方式
// console.log('[交互] --- WebCallApp - 测试 - HWebView')
// // 接收 Web 端数据源
// console.log(value)
//
// // 交互数据处理
// do something ...
//
// // callback
// return value
// }
WebTestAsync = async (value: string): Promise<string> => { // 测试 - 异步
let userInfo: UserInfoModal = JSON.parse(userInfoData)
userInfo.instituteId = instituteId
userInfo.genderCode = genderCode
let commandManager = CommandManager.shareInstance()
let res = await commandManager.webCallAppCommandWithScriptMessage(value, userInfo, this.webView)
let argsJson = JSON.stringify(res.args)
console.log('[WebTestAsync]')
console.log(argsJson)
return argsJson
}
WebTest(value: string): Promise<string> { // 测试 - promise
let p: Promise<string> = new Promise((resolve, reject) => {
let userInfo: UserInfoModal = JSON.parse(userInfoData)
userInfo.instituteId = instituteId
userInfo.genderCode = genderCode
let commandManager = CommandManager.shareInstance()
let res = commandManager.webCallAppCommandWithScriptMessage(value, userInfo, this.webView)
let argsJson = JSON.stringify(res.args)
resolve('[Callback]:' + argsJson)
})
return p
}
}
2.基于 @ohos.web.webview 初始化并配置
官方文档传送门
通过 javaScriptProxy 的代理方法与前端通信接发消息;
1).name 两端交互的协议 key
2).object 对应的是 WebCallApp 的交互接收方法
3).methodList 基于 object 的 WebCallApp 中交互具体实现的若干函数方法
4).controller 组件

3.全局设置
跟目录 main.js 中配置为全局
import webApp from '../src/expand/webApp/index';
import { AppCommendBackHandlers } from "./expand/webApp/AppMsgHandlers";
Vue.prototype.webApp = webApp;
Vue.prototype.WebBack = AppCommendBackHandlers;
4.交互调用
this.webApp.WebCallApp('GetAPPDetail', {'abc': '123'}, (res) => { // 测试: 鸿蒙 jsbridge 交互
console.log('[交互] - 回调');
console.log(res);
});
以上便是此次分享的全部内容，希望能对大家有所帮助！
