相册路径是file://media/Photo/2/IMG_1712804096_001/IMG_20240411_105316.jpg，要怎么变成绝对路径。

      PhotoSelectOptions.maxSelectNumber = 5; 
      let photoPicker = new picker.PhotoViewPicker(); 
      photoPicker.select(PhotoSelectOptions) 
        .then(async (PhotoSelectResult: picker.PhotoSelectResult) => { 
          console.info('PhotoViewPicker.select successfully, PhotoSelectResult uri: ' + JSON.stringify(PhotoSelectResult));
