mp3歌曲怎么下载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
防暑降温费标准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):
灭火的基本方法是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 = ad().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 = repile(r'"name":"(.*?)","tns":[],"alias":[]')
name0 = re.findall(rule0, bs4)
str = ""
for i in name0:
str = str + "," + i
str = place("\xa0", " ")
rule1 = repile(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 = "music.163/song/media/outer/url?id=" + j[2]
content = (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 = "music.163/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")
