在没有FileReader的NodeJS中将Blob转换为Base64

const fs = require('fs');
const util = require('util');
const readFile = util.promisify(fs.readFile);

async function blobToBase64(blobPath) {
  try {
    const data = await readFile(blobPath, 'binary');
    const base64Data = Buffer.from(data, 'binary').toString('base64');
    return base64Data;
  } catch (error) {
    console.error('Error converting blob to base64:', error);
    throw error;
  }
}

// 使用示例
(async () => {
  try {
    const base64Data = await blobToBase64('path/to/your/blob');
    console.log('Base64 data:', base64Data);
  } catch (error) {
    console.error('Error:', error);
  }
})();
