本文分享了一款基于Python的网易云音乐爬虫程序，详细介绍了如何搜索并下载歌曲、歌单及歌手信息，涵盖了从设置Cookie、加密请求到解析JSON响应的全过程。

2015年11月27日 No comments Article

程序源代码如下：

#! /usr/bin/env python
# -*- coding: utf-8 -*-

import md5
import base64
import urllib2
import urllib
import json
import random
import os
import sys
import string

#string.replace(u'xa0', u' ')

reload(sys)
sys.setdefaultencoding('utf-8')

#设置cookie
cookie_opener = urllib2.build_opener()
cookie_opener.addheaders.append(('Cookie', 'appver=2.0.2'))
cookie_opener.addheaders.append(('Referer', 'http://music.163.com'))
urllib2.install_opener(cookie_opener)

#加密
#def encrypted_id(id):
#    byte1 = bytearray('3go8&$8*3*3h0k(2)2')
#    byte2 = bytearray(id)
#    byte1_len = len(byte1)
#    for i in xrange(len(byte2)):
#        byte2[i] = byte2[i]^byte1[i%byte1_len]
#    m = md5.new()
#    m.update(byte2)
#    result = m.digest().encode('base64')[:-1]
#    result = result.replace('/', '_')
#    result = result.replace('+', '-')
#    return result
#
