使用nodejs和rest api从远程机器下载文件

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

const downloadFile = async (url, filePath) => {
  try {
    const response = await axios.get(url, { responseType: 'stream' });
    const writer = fs.createWriteStream(filePath);
    response.data.pipe(writer);

    return new Promise((resolve, reject) => {
      writer.on('finish', resolve);
      writer.on('error', reject);
    });
  } catch (error) {
    console.error('下载文件时发生错误:', error);
    throw error;
  }
};

// 使用示例
const remoteFileUrl = 'https://example.com/remote-file.txt';
const localFilePath = './downloads/remote-file.txt';

downloadFile(remoteFileUrl, localFilePath)
  .then(() => {
    console.log('文件下载完成');
  })
  .catch((error) => {
    console.error('文件下载失败:', error);
  });
