使用Fetch API和fs.createWriteStream对文件进行流响应

fetch('http://example.com/file.pdf')
  .then(response => {
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return response.body;
  })
  .then(body => {
    const fileStream = fs.createWriteStream('path/to/save/file.pdf');
    body.pipe(fileStream);
  })
  .catch(error => {
    console.error('Error:', error);
  });

const fs = require('fs');
const fetch = require('node-fetch');

fetch('http://example.com/file.pdf')
  .then(response => {
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return response.body;
  })
  .then(body => {
    const fileStream = fs.createWriteStream('path/to/save/file.pdf');
    body.pipe(fileStream);
  })
  .catch(error => {
    console.error('Error:', error);
  });
