示例参考如下：

import webView from '@ohos.web.webview';
import business_error from '@ohos.base' ;
import abilityAccessCtrl from '@ohos.abilityAccessCtrl';
import { router } from '@kit.ArkUI';
const AtManager = abilityAccessCtrl.createAtManager();
@Entry
@Component struct WebComponent {
  controller: webView.WebviewController = new webView.WebviewController();
  aboutToAppear() {
    AtManager.requestPermissionsFromUser(getContext(this), ['ohos.permission.MICROPHONE']) .then(
      data => {
        let result: Array<number> = data.authResults;
        let hasPermissions1 = true;
        result.forEach(item => { if (item === -1) { hasPermissions1 = false; } })
        if (hasPermissions1) {
          console.info("hasPermissions1") } else {
          console.info("not hasPermissions1") }
      }).catch((error:business_error.BusinessError) => {}); }
  build() {
    Column() {
      Row() {
        Button('refresh')
          .onClick(() => { this.controller.refresh() })
      }
      Row() {
        Button('跳转')
          .onClick(() => {
            router.pushUrl({
              url: 'pages/Index',
              params: ''
            })
          })
      }
      Row() {
        Web({ src: $rawfile('demo.html'), controller: this.controller })
          .domStorageAccess(true)
          .databaseAccess(true)
          .imageAccess(true)
          .onlineImageAccess(true)
          .javaScriptAccess(true)
          .onScreenCaptureRequest((event) => {
            if (!event) { return; }
            console.log("on onScreenCaptureRequest Origin:" + event.handler.getOrigin());
            AlertDialog.show({ title: 'title', message: '请求权限' + event.handler.getOrigin(), confirm: { value: 'ok', action: () => { event.handler.grant({ captureMode: WebCaptureMode.HOME_SCREEN }); } }, cancel: () => { event.handler.deny(); } })
          })
      }
    }
  }
}
