ionic 将 base64 字符串保存为图库中的图像

ionic save base64 string as image in galary

   ngOnInit(){

        this.photos=[];
      }

      takePhotos(){

        const options: CameraOptions = {

          quality: 30,
          destinationType: this.camera.DestinationType.DATA_URL,   
          encodingType: this.camera.EncodingType.JPEG,
          mediaType: this.camera.MediaType.PICTURE,
        }
        this.camera.getPicture(options).then((imageData) => {
         // imageData is either a base64 encoded string or a file URI
         // If it's base64:
         this.base64Image = 'data:image/jpeg;base64,' + imageData;

         this.photos.push(this.base64Image);
         this.photos.reverse();
        }, (err) => {
         // Handle error
        });
      }

带有相机插件img的ionic应用程序点击并显示在屏幕上,如何将这个base64字符串保存为galary中的图像并获取每个img保存的路径?任何人都可以用一个简单的例子来描述吗?

  const options: CameraOptions = {
  quality: 30,
  destinationType: this.camera.DestinationType.DATA_URL,   
  encodingType: this.camera.EncodingType.JPEG,
  mediaType: this.camera.MediaType.PICTURE,
  saveToPhotoAlbum : true
}

只需添加此行 saveToPhotoAlbum : true 即可开始在 galary 中保存图像。
