首先找到要下载的歌曲排行榜的链接，这里用的是：

https://music.163.com/discover/toplist?id=3778678

然后更改你要保存的目录，目录要先建立好文件夹，例如我的是保存在D盘-360下载-网易云热歌榜文件夹内，就可以完成下载。

如果文件夹没有提前建好，会报错[Errno 2] No such file or directory。

代码实现：

from urllib import request

from bs4 import BeautifulSoup

import re

import requests

import time

class Music(object):

def __init__(self, baseurl, path):

head = {

"user-agent": "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/69.0.3497.100 Safari/537.36"

}

self.baseurl = baseurl

self.headers = head

self.path = path

def main(self):

html = self.askurl()

bs4 = self.analysis(html)

name1 = self.matching(bs4)

self.save(name1)

def askurl(self):

req = request.Request(url=self.baseurl, headers=self.headers)

response = request.urlopen(req)

html = response.read().decode("utf-8")

return html

def analysis(self, html):

soup = BeautifulSoup(html, "html.parser")

bs4 = soup.find_all("textarea")

bs4 = str(bs4)

return bs4

def matching(self, bs4):

rule0 = re.compile(r'"name":"(.*?)","tns":[],"alias":[]')

name0 = re.findall(rule0, bs4)

str = ""

for i in name0:

str = str + "," + i

str = str.replace("\xa0", " ")

rule1 = re.compile(r'jpg,(.*?),(.*?)","id":(\d*)')

name1 = re.findall(rule1, str)

return name1

def save(self, name1):

for j in name1:

print("正在下载：" + j[1] + " - " + j[0] + "...")

url = "http://music.163.com/song/media/outer/url?id=" + j[2]

content = requests.get(url=url, headers=self.headers).content

with open(self.path + j[1] + " - " + j[0] + ".mp3", "wb") as f:

f.write(content)

print(j[1] + " - " + j[0] + "下载完毕。\n")

time.sleep(0.5)

return

if __name__ == "__main__":

baseurl = "https://music.163.com/discover/toplist?id=3778678" # 要爬取的热歌榜链接

path = "D:/360下载/网易云热歌榜/" # 保存的文件目录

demo0 = Music(baseurl, path)

demo0.main()

print("下载完毕")
