爬取网易云音乐MP3链接脚本

直接上代码。

代码部分：

import json
from urllib.request import urlopen
from urllib.error import HTTPError

print("*" * 8,"网易云音乐下载器", "*" * 8,"\n")
ID = input('请输入歌曲ID:\n>>> ')
url = "http://music.163.com/api/song/detail/?ids=[" + ID + "]" #这个URL比较重要
html = urlopen(url).read().decode("utf-8")
rejson = json.loads(html)
for name in rejson['songs']:
    print('歌曲ID: ',name['id'])
    print('歌曲名称: ',''.join(name['name']))
    print('歌手: ',''.join(names['name'] for names in name['artists']))
    print('mp3链接: ',name['mp3Url'])

num = int(input('\n是否下载?(输入1下载该歌曲,输入其他数字关闭程序.)\n'))
if num == 1:
    try:
        f = open(str(''.join(name['name']) + "-" + ''.join(names['name'] for names in name['artists'])) + ".mp3", "wb")
        req = urlopen(name['mp3Url'])
        buf = req.read()
        f.write(buf)
        f.close()
        print("已保存")
    except HTTPError as e:
        print("遇到错误啦! 错误代码是这个: \n",">>>>>>",e,"<<<<<<","\n我猜这是付费歌曲的'ID'，可能是网站不让下载吧！")
elif num != 1:
    print("已关闭")

找网易云音乐歌曲的ID方法：在网易云音乐搜索到该歌曲，打开播放页面，在浏览器地址栏后显示该歌曲ID。

电影《功夫瑜伽》主题曲

一般情况下可以找到歌曲的链接，付费歌曲也可以找到链接，但是返回404错误。

代码很简单，现在还没发现其他问题。

今天更新了这段代码：

        return ID
    except:
        print("请输入正确的ID！\n")
        getId()

getUrl(song, name, mp3url)
