使用电容器和离子显示图像时出错

Question

I am trying to write a simple Camera app using Ionic 4 and here is my code snippet for capturing the image and displaying it in an Ionic tab.

export class UploadPage {
  yourImage: SafeResourceUrl;

  constructor(private sanitizer: DomSanitizer) {  }

  async captureImage() {
    const capturedImage = await Plugins.Camera.getPhoto(
    {
      quality: 90,
      allowEditing: true,
      source: CameraSource.Camera,
      resultType: CameraResultType.Uri
    });

    this.yourImage = this.sanitizer.bypassSecurityTrustResourceUrl(capturedImage && (capturedImage.dataUrl));

    }
  }

When I try to run the code, it looks like it's capturing the image ok but it's not displaying in the browser. I see this

In the web console, I see this

The image doesn't show up in devapp as well.

The weird thing is, when I tested this out on an Android phone, the image saved fine on the disk but it still doesn't show on the page.

If you use resultType Uri you have to use capturedImage.webPath to display the url, the dataUrl is undefined unless you se resultType DataUrl
