之前看到有人写过类似的代码,感觉有点累赘,其中登陆那些东西其实可以避免的
我把百度音乐的网页代码稍微分析了一下,如果要求不高,下载普通音质的歌曲是不需要登陆的(当然如果你用浏览器打开下载的话,普通音质也是要求登陆下载的)
看其代码发现,即使你没有登陆,其实下载链接也已经暴露出来了,只是用javascript阻止了你在浏览器中下载,
我下面写了一个下载的demo,顺便测试了一下多进程,批量下载很实用:
#!/usr/bin/env python #-*- coding: UTF-8 -*- import sys,os import urllib,urllib2 from bs4 import BeautifulSoup import json from multiprocessing import Process class BaiDuMusic(): def __init__(self): reload(sys) sys.setdefaultencoding('utf8') def search(self,songName): firstUrl = "http://music.baidu.com/search?key="+urllib.quote(str(songName)) userAgent = " User-Agent:Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/39.0.2171.71 Safari/537.36 " headers = { 'User-Agent' : userAgent } requst = urllib2.Request(firstUrl,headers = headers) result = urllib2.urlopen(requst).read() #使用BeautifulSoup快速解析html文档 soup = BeautifulSoup(result,from_encoding="utf-8") res_arr = [] try: tmpjson = soup.find_all("li", { "class" : "bb-dotimg clearfix song-item-hook " }) for x in tmpjson: tmpobj = json.loads(x['data-songitem']) value = unicode(tmpobj['songItem']['oid'])+"+++"+unicode(tmpobj['songItem']['author'])+"+++"+unicode(tmpobj['songItem']['sname'])[4:-5] res_arr.append(value) return res_arr except Exception, e: print u"抱歉没有找到相关资源".encode("utf-8") return 0 def download(self,songid,songName,savePath="down/"): songNewUrl = "http://music.baidu.com/data/music/file?link=&song_id="+str(songid) if not os.path.isdir(savePath): os.makedirs(savePath) savemp3 = savePath.decode('utf-8')+songName.decode('utf-8')+u".mp3" urllib.urlretrieve(songNewUrl, savemp3) if __name__=='__main__': bMusic = BaiDuMusic() res = bMusic.search(u"冰雨") # for x in res: # print x # 1128053+++刘德华+++冰雨 # 7327899+++李翊君+++冰雨 # 53535187+++张恒+++冰雨 Process(target=bMusic.download, args=(1128053,"刘德华-冰雨")).start() Process(target=bMusic.download, args=(7327899,"李翊君-冰雨")).start() Process(target=bMusic.download, args=(53535187,"张恒-冰雨")).start()
多次测试发现还有一些小问题,比如你搜的歌曲不完整,歌曲:”我可以抱你吗“,你搜的是“我可以抱你” 那么结果会把“我可以抱你”加上em标签
上面代码是没有去掉的,需要用正则处理一下
