HarmonyOS 鸿蒙Next WebView 加载网页白屏

开发者您好，页面应该使用了数据存储相关功能，加上这些权限可以加载出来：

import web_webview from '@ohos.web.webview';

import business_error from '@ohos.base';

import { url } from '@kit.ArkTS';

import { router } from '@kit.ArkUI';

@Entry

@Component

struct WebComponent {

  @State userAgent:string = ""Mozilla/5.0 (Phone; OpenHarmony 5.0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36  ArkWeb/4.1.6.1 Mobile""

  params = router.getParams() as URLStringRouteInfo

  urlString?: string | null = 'http://'

  webviewController: web_webview.WebviewController = new web_webview.WebviewController();

  build() {

    Column() {

      Web({ src: ""https://m.zcygov.cn/luban/privacy_policy?hideTitle=1"", controller: this.webviewController}).onControllerAttached(()=>{

            this.webviewController.setCustomUserAgent(this.userAgent)

          })

        //加上以下权限

        .fileAccess(true)

        .javaScriptAccess(true)

        .domStorageAccess(true)

        .onlineImageAccess(true)

    }

  }

}

class URLStringRouteInfo {

  urlString?: string | null = 'http://'

}
