let reportContainer = <HTMLElement>document.getElementById('reportContainer');
this.report = this.powerbi.load(reportContainer, this.config);
let reportObject = <pbi.Report>this.report;
this.report.on("loaded", (result) => {
  console.log("loaded");
  reportObject.getPages().then(result => {
    console.log("sucessfully got pages");
    this.pages = result;
    result.forEach(element => {
      var page = <pbi.Page>element;
      console.log("A Page:" + page.displayName);
      page.getVisuals().then(visualSucessResult => {
        console.log("get Visuals sucess");
        visualSucessResult.forEach(aVisualElement => {
          var aVisual = <pbi.VisualDescriptor>aVisualElement;
          console.log("aVisual.name:" + aVisual.name);
        });
      }, visualFailureResult => {
          console.log("Get Visual Failed");
        })
    });
  }, error => {
    console.log("Error getting Pages");
  })
});

我正在尝试加载一个报告并获取报告的页面,然后获取每个页面的视觉效果。当我得到视觉效果时,它无法获得视觉效果。似乎报表的视觉效果不包含代码试图获取的某些属性,但我在报表中找不到任何错误。我已经花了几个小时了,这似乎是一个愚蠢的错误,我无法弄清楚。我是用角度5写的

这确实是GETVisualAPI的一个限制。我把这个添加到wiki页面,一旦这个限制被删除,我会在这里发布。
