requests是python的一个HTTP客户端库，跟urllib，urllib2类似，但比那两个要简洁的多，至于request库的用法，
推荐一篇不错的博文：https://cuiqingcai.com/2556.html
话不多说，先说准备工作：
1，下载需要的库：request，BeautifulSoup( 解析html和xml字符串),xlwt(将爬取到的数据存入Excel表中)
2，至于BeautifulSoup 解析html方法，推荐一篇博文：http://blog.csdn.net/u013372487/article/details/51734047
3，re库，我们要用正则表达式来筛选爬取到的内容
好的，开始爬：
首先我们找到网易云音乐华语男歌手页面入口的URL：url = 'http://music.163.com/discover/artist/cat?id=1001'
把整个网页爬取下来: html= requests.get(url).text
soup = BeautifulSoup(html,'html.parser'
我们要找到进入top10歌手页面的url,用浏览器的开发者工具，我们发现歌手的信息
都在<div class="u-cover u-cover-5">......</div>这个标签里面，如图：
于是，我们把top10歌手的信息筛选出来：
top_10 = soup.find_all('div',attrs = {'class':'u-cover u-cover-5'})
singers = []
for i in top_10:
singers.append(re.findall(r'.*?<a class="msk" href="(/artist\?id=\d+)" title="(.*?)的音乐"></a>.*?',str(i))[0])
获取到歌手的信息后，依次进入歌手的界面，把他们的热门歌曲爬取并写入Excel表中，原理同上
附上完整代码：
import xlwt
import requests
from bs4 import BeautifulSoup
import re url = 'http://music.163.com/discover/artist/cat?id=1001'#华语男歌手页面
r = requests.get(url)
r.raise_for_status()
r.encoding = r.apparent_encoding
html=r.text #获取整个网页 soup = BeautifulSoup(html,'html.parser') #
top_10 = soup.find_all('div',attrs = {'class':'u-cover u-cover-5'})
#print(top_10) singers = []
for i in top_10:
singers.append(re.findall(r'.*?<a class="msk" href="(/artist\?id=\d+)" title="(.*?)的音乐"></a>.*?',str(i))[0])
#print(singers) url = 'http://music.163.com'
for singer in singers:
try:
new_url = url + str(singer[0])
#print(new_url)
songs=requests.get(new_url).text
soup = BeautifulSoup(songs,'html.parser')
Info = soup.find_all('textarea',attrs = {'style':'display:none;'})[0]
songs_url_and_name = soup.find_all('ul',attrs = {'class':'f-hide'})[0]
#print(songs_url_and_name)
datas = []
data1 = re.findall(r'"album".*?"name":"(.*?)".*?',str(Info.text))
data2 = re.findall(r'.*?<li><a href="(/song\?id=\d+)">(.*?)</a></li>.*?',str(songs_url_and_name)) for i in range(len(data2)):
datas.append([data2[i][1],data1[i],'http://music.163.com/#'+ str(data2[i][0])])
#print(datas)
book = xlwt.Workbook()
sheet1=book.add_sheet('sheet1',cell_overwrite_ok = True)
sheet1.col(0).width = (25*256)
sheet1.col(1).width = (30*256)
sheet1.col(2).width = (40*256)
heads=['歌曲名称','专辑','歌曲链接']
count=0 for head in heads:
sheet1.write(0,count,head)
count+=1 i=1
for data in datas:
j=0
for k in data:
sheet1.write(i,j,k)
j+=1
i+=1
book.save(str(singer[1])+'.xls')#括号里写存入的地址 except:
