HarmonyOS 鸿蒙Next Web组件如何加载wasm文件

参考如下示例：

import webview from '[@ohos](/user/ohos).web.webview';

[@Entry](/user/Entry)
[@Component](/user/Component)
struct MainPage {
 [@State](/user/State) isLoading: boolean = true
 [@State](/user/State) msg: string = ""
 controller: webview.WebviewController = new webview.WebviewController();

 aboutToAppear() {
   webview.WebviewController.setWebDebuggingAccess(true);
 }

 build() {
   Row() {
     Column() {
       Stack() {
         Web({ src: "https://www.ahahahah/index.html", controller:this.controller })
