webview某些url加载空白,链接本身没问题咋回事？

struct WebComponent {
  @State webBusiness: webBusinessToH5 = new webBusinessToH5();
  webviewController: web_web.WebviewController = new web_web.WebviewController();
   url: string = 'https://h5test.ichangtou.com/research/ichangtou/ict-h5-bridge-app/index.html';
    // url: string = 'https://www.baidu.com';

  build() {
    Column() {

      Web({ src: this.url, controller: this.webviewController})

      .onPageEnd((event) => {
        // 注册事件
        this.webviewController.registerJavaScriptProxy(this.webBusiness, "webBusinessToH5", ["test", "getUserInfo"]);
      })
        
    }
  }



}
