    利用python爬取网易云音乐热歌榜

    FXLFXL2020-08-06 17:26:20转载2354

    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")
