python批量下载网易云音乐文件到本地

现在听歌大多数只支持在线听，下载要钱，没网络就白搭了。好吧，用技术手段解决免费、下载、批量等一些列问题

整个脚本的逻辑和流程是，把歌曲地址都存在一个txt中，然后循环每次取一条链接，分析链接对应歌曲的id和歌曲名，然后下载该歌曲，同时已歌曲名命名下载后的文件

网易云音乐客户端复制音乐地址，比如上面那首《踏山河》：https://music.163.com/song?id=1804320463&userid=502092978

歌曲地址内有可以看到id=1804320463，需要把这串数字分离出来，后面下载会用到，用正则分离出来

url=“https://music.163.com/song?id=1804320463&userid=502092978“”
song_id=re.findall('id=(.+?)&userid',url)[0]

然后根据地址获取歌曲名称，这里使用的是xpath爬虫抓取数据

song_url=“https://music.163.com/song?id=1804320463&userid=502092978“”
response = requests.get(song_url,headers)
wb_data = response.text # 将页面转换成文档树
html = etree.HTML(wb_data)
music_name = html.xpath('//em[@class = "f-ff2"]/text()')[0]

再就是下载歌曲，下载歌曲需要用到网易云的专属下载接口，http://music.163.com/song/media/outer/url?id=，id=后面即填入上面步骤分离出来的歌曲id

response = requests.get("http://music.163.com/song/media/outer/url?id="+song_id+".mp3")
        content = response.content
        with open(music_name+'.mp3', mode="wb") as f:
            f.write(content)
        print("下载"+"   "+music_name+"  "+"完成")

然后在脚本目录下创建一个txt文件，把歌曲地址复制到文本内（每行一条地址）

为了方便观察每一步获取的数据，再每一步操作后面加入把数据打印出来，执行脚本

以上即是本案例的主要步骤和对应的脚本，至于读取txt文件等，就参考后面附上的所有脚本内容

同时，已经把脚本打包成exe文件，没有安装python的电脑环境也可以执行（加微信xiaobeishuwu发文件）

特别强调，不要下的太过分，仅仅是技术交流，商业牟利自负责任
