在react-native上将base64转换为blob时出现Fetch错误

import { fetch } from 'react-native-fetch-api'; // 确保你已经安装了react-native-fetch-api

const base64String = 'your-base64-string-here';

const convertBase64ToBlob = async (base64) => {
  try {
    const response = await fetch('data:;base64,' + base64);
    const blob = await response.blob();
    return blob;
  } catch (error) {
    console.error('Error converting base64 to blob:', error);
    throw error;
  }
};

convertBase64ToBlob(base64String)
  .then(blob => {
    console.log('Blob created:', blob);
  })
  .catch(error => {
    console.error('Failed to create blob:', error);
  });
