如何在React Native中将base64字符串图像转换为blob？

npm install react-native-fetch-blob --save

import RNFetchBlob from 'react-native-fetch-blob';

const base64ToBlob = (base64) => {
  const base64Data = base64.replace(/^data:image\/\w+;base64,/, '');
  const byteCharacters = atob(base64Data);
  const byteArrays = [];

  for (let i = 0; i < byteCharacters.length; i++) {
    byteArrays.push(byteCharacters.charCodeAt(i));
  }

  const byteArray = new Uint8Array(byteArrays);
  return new Blob([byteArray], { type: 'image/jpeg' });
};

const base64Image = 'your_base64_image_string';
const blobImage = base64ToBlob(base64Image);
