一、介绍 🚀 ✈️ 🚁 🚂
我在第五章已经有一篇Electron爬虫的文章，主要写的爬取图片资源的案例。这篇开始讲解如何到一个音乐网站爬取音乐资源，并且进行在线播放，下载等等。
那么什么是爬虫呢。百度百科上爬虫既是网络爬虫（又称为网页蜘蛛，网络机器人，在FOAF社区中间，更经常的称为网页追逐者），是一种按照一定的规则，自动地抓取万维网信息的程序或者脚本。我个人的理解就是，爬虫是一种自动化程序，它可以模拟人类浏览网页的行为，从互联网上爬取数据并进行处理。
二、爬虫准备 🚀 ✈️ 🚁 🚂
1、编程语言准备 🔅 🔅 🔅
除了node爬虫，常用的编程语言还有Python、Java、C++等，其中Python是最为流行的爬虫语言之一。不管是那种，思路和步骤基本上都是一样的。
2、数据储存 🔅 🔅 🔅
爬虫爬取的数据需要进行存储，常用的数据存储方式有MySQL、MongoDB、Redis、SQLite3、Excel、txt、json等。具体采用什么方式储存需要看具体的数据类型、结构、大小等。
3、资源网站的观察 🔅 🔅 🔅
在开始爬虫之前我们得去资源网站进行观察，python、java、node等语言爬虫都是需要对网站结构进行分析的。比如我们需要爬取一个网站内的分类，对于其他非分类的内容来说是没有任何意义的。可以观察网站中分类是否具有唯一的class或者id，又或者分类是在div容器中还是ul容器中。根据多方面的条件能够让我们很快，也能最简单的去通过一些工具取到想要的内容。这是结构的一个观察，还有请求的要求，有些接口请求的话会有一些繁琐的头部定义（Header）。如果不设置的话可能会出现401、404、50*等等各种情况。这些都是需要我们去观察以后，在脚本中去进行设置的。
三、爬虫能够做些啥 🚀 ✈️ 🚁 🚂
1、数据采集 🔅 🔅 🔅 🔅
爬虫可以自动化地从互联网上采集数据，包括文字、图片、音乐、视频等。
2、数据分析 🔅 🔅 🔅 🔅
爬虫可以对采集到的数据进行分析和处理，例如数据清洗、数据挖掘等。
3、搜索引擎优化 🔅 🔅 🔅 🔅
爬虫可以帮助网站提升搜索引擎排名，从而增加网站的流量和曝光度。
4、网络安全 🔅 🔅 🔅 🔅
爬虫可以帮助企业进行网络安全测试，发现漏洞和安全隐患。
四、爬虫技巧 🚀 ✈️ 🚁 🚂
1、合理设置爬虫请求频率，避免对服务器造成过大的负担。🔅 🔅 🔅
2、使用多个IP地址进行爬取，避免被封禁。🔅 🔅 🔅
3、使用随机的User-Agent头信息，避免被网站识别为爬虫。🔅 🔅 🔅
4、避免爬取敏感信息，遵守网站的robots.txt协议。🔅 🔅 🔅
五、开始爬取音乐 🚀 ✈️ 🚁 🚂
安装依赖
yarn add cheerio
yarn add @types/cheerio -D这里的话具体的网站地址我就不放出来了，避免一些不必要的麻烦，如果有需要的小伙伴可以私信我。
首先我搜索周杰伦以后，就会出来一个搜索结果的页面，页面内还包含了分页数据。所以页面内我需要的数据就是内容和分页。通过对页面的分析，$('.list-unstyled .media')就能帮我定位到内容。
$('.pagination li')就能帮我定位的分页。
点击相对应的歌曲进入以后，我们还可以获取到歌曲的相信信息，歌曲名称、歌手、歌词等等
当我们点击播放的时候，可以在Network中观察到，它请求的地址，这个地址复制在浏览器中打开是可以直接播放音乐的。也能直接下载，所有我们需要这个地址。
综合以上的全部分析，具体的实现代码如下：
/** 根据歌曲名称查询对应的列表
* @Description:
* @CreationDate 2023-05-08 10:11:51
*/
getListByMusicName(musicName: string, page?: number) {
if (!page) {
this.resetGetParam(musicName)
}
const path = `search-${encodeURIComponent(musicName)}-1-${ page ? page : this.queryMusicResult.music_current_page }.htm`
try {
axios.get('https://www.******.com/' + path).then((res: any) => {
const $: any = cheerio.load(res.data)
const musicContent = $('.list-unstyled .media')
const pagination = $('.pagination li')
// 获取总页数
if (pagination.eq(pagination.length - 2).children('a').html()) {
const pageTotal = (pagination.eq(pagination.length - 2).children('a').html()).match(/\d+/g)[0]
if (pageTotal && pageTotal > 0) {
this.queryMusicResult.music_page_count = Number(pageTotal)
}
}
if (this.queryMusicResult.music_current_page === this.queryMusicResult.music_page_count) {
this.queryMusicResult.music_noMore = true
}
// 如何搜索出的结果为0就直接结束
if (musicContent.length === 0) {
this.queryMusicResult.music_loading = false
this.queryMusicResult.music_noMore = false
} else {
this.circulateGetMusicList(musicContent)
}
}).catch((e: any) => {
this.queryMusicResult.music_loading = false
console.log('👉👉👉-----------------', e);
})
} catch (e) {
this.queryMusicResult.music_loading = false
console.log('👉👉👉-----------------', e);
}
},
/**
* @Description: 循环查询当前页面的歌曲相关信息
* @CreationDate 2023-05-08 11:48:43
*/
circulateGetMusicList(musicContent: any) {
try {
for (let i = 0; i < musicContent.length; i++) {
const musicHref = musicContent['eq'](i).children('div .media-body').children('div .subject').children('a')
axios.get('https://www.*****.com/' + musicHref.attr('href')).then(info => {
const $info: any = cheerio.load(info.data)
const musicInfo = $info('.card-thread')['children']('div .card-body').children('div .break-all')
if (musicContent.length === (i + 1)) {
this.queryMusicResult.music_loading = false
}
if (musicInfo.children('script') && musicInfo.children('script').get(1) && musicInfo.children('script').get(1).children) {
const musicInfos = musicInfo.children('script').get(1).children[0]['data']
const S = musicInfos.indexOf('[')
const E = musicInfos.indexOf(']')
let data = musicInfos.substring(S + 1, E - 3).replace(/\s*/g, '')
if (data) {
data = data.substring(0, data.length - 1)
data = eval('(' + data + ')')
this.queryMusicResult.music_current_list.push({
name: data.title,
url: data.url.includes('https') ? data.url.replace('-', '%20-%20') : 'https://www.*****.com/' + data.url,
author: data.author,
pic: data.pic
} as MusicType)
}
}
})
}
} catch (e) {
this.queryMusicResult.music_loading = false
console.log('👉👉👉-----------------', e)
}
},这里的话我们就实现了爬虫的部分代码，是不是超级简单，现在就要对爬取的资源进行一个展示，以及音乐的播放，下载等等。
我将上一章中的目录结构进行了更改。创建src/views/music目录，原本home下面的index.vue更改为localAndDownload.vue，并移动到music目录下。同时创建index.vue页面。接下来，我们将爬取的资源在music/index.vue中进行一个实现。
六、完整案例 🚀 ✈️ 🚁 🚂
首先创建路由。这里的话我就不做菜单了，自行去完成，我直接将根路径访问指向music/index
import { createRouter, createWebHashHistory, RouteRecordRaw } from 'vue-router'
export const asyncRoutes: RouteRecordRaw[] = [
{
path: '/',
component: () => import('@/views/music/index.vue')
},
{
path: '/home',
component: () => import('@/views/home/index.vue')
},
{
path: '/401',
component: () => import('@/views/401.vue'),
},
{
path: '/localAndDownload',
component: () => import('@/views/music/localAndDownload.vue')
},
]
const router = createRouter({
history: createWebHashHistory(),
routes: asyncRoutes,
scrollBehavior: () => ({ left: 0, top: 0 })
})
export default router
修改src/views/music/index.vue
