Python爬虫 - 网易云音乐下载

爬取网易云音乐实战，仅供学习，不可商用，出现问题，概不负责！

分为爬取网易云歌单和排行榜单两部分。

因为网页中，只能显示出歌单的前20首歌曲，所以仅支持下载前20首歌曲（非VIP音乐）

在这里插入图片描述

具体过程：

1.通过抓包，获取到请求头

在这里插入图片描述

headers = {
    "user-agent": "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/114.0.0.0 Safari/537.36",
    "Cookie": "替换为自己的Cookie",
    "Sec-Ch-Ua-Platform": "macOS",
    "Sec-Fetch-Dest": "iframe",
    "Sec-Fetch-Mode": "navigate",
    "Sec-Fetch-Site": "same-origin",
    "Upgrade-Insecure-Requests": "1"
}

2.发送请求，获取到网页源代码，通过Xpath进行解析，获取到歌曲名称，歌手名字，以及歌曲id

url = input("请输入要抓取的歌单链接：")
url = url.replace("/#", "")
res = requests.get(url, headers=headers)
res.encoding = 'utf-8'
res = res.text
html = etree.HTML(res)
title = html.xpath('//h2[@class="f-ff2 f-brk"]/text()')
songs = html.xpath('//ul[@class="f-hide"]/li/a/@href')
names = html.xpath('//ul[@class="f-hide"]/li/a/text()')

3.并分别对歌单创建单独的文件夹，进行歌曲存放

if len(title)!=0:
    path = './网易云歌单/' + title[0] + "/"
else:
    path = "./网易云歌单/未知歌单/"

if not os.path.exists(path):
    os.makedirs(path)

4.判断是否为VIP歌曲，将VIP歌曲排除

for i in range(len(music_urls)):
    try:
        res = requests.get(music_urls[i], headers=headers).content.decode('utf-8')
        if res.find('很抱歉，你要查找的网页找不到') != -1:
            print(names[i] + '，VIP专属歌曲，无法下载')
            remove_url.append(music_urls[i])
            remove_name.append(names[i])
            continue
    except:
        pass
for item in remove_name:
    names.remove(item)
for url in remove_url:
    music_urls.remove(url)

5.下载歌曲

for i in range(len(music_urls)):
    try:
        print('正在下载..', names[i])
        res = requests.get(music_urls[i], headers=headers)
        with open(path + names[i] + ".mp3", "wb") as f:
            f.write(res.content)
        print('下载成功..', names[i])
    except Exception as e:
        if os.path.exists(path + names[i] + ".mp3"):
            os.remove(path + names[i] + ".mp3")
        print('下载失败，请联系管理员')

6.对于排行榜部分，和歌单逻辑基本相同

url = input("请输入榜单链接：")
url = url.replace("/#", "")
res = requests.get(url, headers=headers)
res.encoding = 'utf-8'
res = res.text
html = etree.HTML(res)
title = html.xpath('//h2[@class="f-ff2"]/text()')
songs = html.xpath('//ul[@class="f-hide"]/li/a/@href')
names = html.xpath('//ul[@class="f-hide"]/li/a/text()')
if len(title)!=0:
    path = './网易云歌单/' + title[0] + "/"
else:
    path = "./网易云歌单/未知歌单/"

if not os.path.exists(path):
    os.makedirs(path)

for item in songs:
    temp = str(item).replace("/song?id=", "")
    ids.append(temp)

music_urls = []
for id in ids:
    music_urls.append(baseUrl + id + '.mp3')
downLoad(music_urls, names, path)
