createReadStream不接受blob url吗？

const fetch = require('node-fetch');
const fs = require('fs');
const { createReadStream } = require('fs');

async function downloadBlobUrl(blobUrl, filePath) {
  const response = await fetch(blobUrl);
  const buffer = await response.buffer();
  fs.writeFileSync(filePath, buffer);
}

const blobUrl = 'https://example.com/blob-url';
const filePath = 'path/to/file.txt';

downloadBlobUrl(blobUrl, filePath)
  .then(() => {
    const stream = createReadStream(filePath);
    // 在这里可以使用stream进行文件读取操作
  })
  .catch((error) => {
    console.error('下载或读取文件时发生错误：', error);
  });
