我正在执行以下代码,但是在我的设备上,我可以看到损坏的图像而没有任何信息(甚至稍等片刻即可加载图像...),这是我的代码:

TypeScript

FindAll()

HTML

    goPhotoGallery() {
    const options: CameraOptions = {
      quality: 80,
      destinationType: this.camera.DestinationType.FILE_URI,
      encodingType: this.camera.EncodingType.JPEG,
      mediaType: this.camera.MediaType.PICTURE,
      sourceType: this.camera.PictureSourceType.PHOTOLIBRARY,
      correctOrientation: true,
    }

    this.camera.getPicture(options).then((imageData) => {
      // imageData is either a base64 encoded string or a file URI
      // If it's base64 (DATA_URL):
      let base64Image = 'data:image/jpeg;base64,' + imageData;
      this.images = base64Image;
    }, (err) => {
      // Handle error
    });

我该怎么做才能正确显示图像?

使用括号{{images}}

<ion-content padding>

  <ion-card>
    <img src="{{ images }}"  />
  </ion-card>

</ion-content>
