HarmonyOS webview组件内容显示空白

把this.controller.loadData(this.content, “text/html”, “UTF-8”, " ", " ");放到页面前置aboutToAppear这加载，并等待异步方法执行完成

参考以下示例：

async aboutToAppear() {
  const params: ArticleTmp = router.getParams() as ArticleTmp
  await ArticleModel.detail(params.ID).then(data => {
    this.title = data.title
    this.content = ResultContent(data.content)
    this.videos = data.videos
    this.source = data.source
    this.publishtime = data.publishtime
    this.editor = data.editor
    this.proofreader = data.proofreader
    // console.log(data.content)
    console.log(this.content)
    console.log(this.title)
    // console.log(JSON.stringify(data))
  })
}
