如何使用axios库在Node.js中进行代理请求(实践案例)

npm install axios cheerio

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

const proxyAxios = axios.create({
  baseURL: 'https://proxy.example.com', // 代理服务器地址
});

const axios = require('axios');
const fs = require('fs');
const cheerio = require('cheerio');
// 设置代理信息
const proxyHost = "www.16yun.cn";
const proxyPort = "5445";
const proxyUser = "16QMSOML";
const proxyPass = "280651";
// 创建代理axios实例
const proxyAxios = axios.create({
  baseURL: 'https://y.qq.com',
  proxy: {
    host: proxyHost,
    port: proxyPort,
    auth: {
      username: proxyUser,
      password: proxyPass
    }
  }
});
// 发送代理请求获取QQ音乐网站页面内容
proxyAxios.get('/')
  .then(response => {
    // 解析HTML内容
    const $ = cheerio.load(response.data);
    const songs = [];
    // 提取歌曲数据
    $('.song-list .song-item').each((index, element) => {
      const song = {
        name: $(element).find('.song-name').text(),
        singer: $(element).find('.singer-name').text(),
        album: $(element).find('.album-name').text(),
      };
      songs.push(song);
    });
    // 将歌曲数据保存到本地文件
    fs.writeFile('songs.json', JSON.stringify(songs, null, 2), err => {
      if (err) {
        console.error('保存文件发生错误：', err);
      } else {
        console.log('歌曲数据已保存到songs.json');
      }
    });
  })
  .catch(error => {
    console.error('代理请求发生错误：', error);
  });
