如何使axios流读取+文件写入同步？

npm install axios fs

const axios = require('axios');
const fs = require('fs');

axios({
  method: 'get',
  url: 'http://example.com/file.txt',
  responseType: 'stream'
})
  .then(response => {
    // 创建可写流
    const writer = fs.createWriteStream('output.txt');
    // 将响应流管道传输到可写流
    response.data.pipe(writer);

    // 监听可写流的关闭事件
    writer.on('close', () => {
      console.log('文件写入完成');
    });
  })
  .catch(error => {
    console.log('请求出错:', error.message);
  });
