base64 - 如何在 React Native 中获取图像的 base64

Question

我正在使用 native 图像选择器和图像调整器来选择然后调整图像大小。调整大小后如何获取图像的base64？

ImagePickerManager.showImagePicker(imagepicker_options, (response) => {
  ImageResizer.createResizedImage(response.uri, 550, null, 'JPEG', 100).then((resizedImageUri) => {
    //get base64 of image
  });
});

https://libraries.io/npm/react-native-asset-library-to-base64

ImagePickerManager.showImagePicker(imagepicker_options, (response) => {
  ImageResizer.createResizedImage(response.uri, 550, null, 'JPEG', 100).then((resizedImageUri) => {
      //get base64 of image, uri is link to asset-library://
      ReadImageData.readImage(uri, (imageBase64) => {
    console.log(imageBase64);
    });
  });
});
