这次比2345电影那个多了一个resource.py文件,里面包含UserAgents,PROXIES,这样我们在爬取时可以写一个函数,随机从这两项中选取,以此绕开反爬虫. 1.目标:音悦台-V榜-MV作品榜 2.所使用的库: from bs4 import BeautifulSoup import requests import codecs import time import resource import random测试环境 Python 3.6.0 3.目标链接 http://vchart.yinyuetai.com/vchart/trends?area=ML&page=2 通过点击图中红圈部分观察后,发现area=后面的和&page=后面的会变化 (1)写一个url地址拼接的函数 这样urls列表中就保存了我们想要的链接地址 def getUrls(self): areas = ['ML','HT','US','KR','JP'] pages =[str(i) for i in range(1,4)] for area in areas: urls =[] for page in pages: urlEnd = 'area='+area+'&page='+page url = self.urlBase+urlEnd urls.append(url) self.spider(area,urls)(2)我们再来看一些spider()函数 def spider(self,area,urls): items = [] for url in urls: html = self.getResponseContent(url) if not html: continue soup = BeautifulSoup(html,'lxml') tags = soup.find_all('li',attrs={'name':'dmvLi'}) # tags = soup.find_all('li',attrs={'class','vitem J_li_toggle_date'}) for tag in tags: item = Item() item.top_num = tag.find('div',attrs={'class':'top_num'}).get_text() # if tag.find('h3',attrs={'class':'desc_score'}): # item.score = tag.find('h3',attrs={'class':'des_score'}).text() # else: # item.score = tag.find('h3',attrs={'class':'asc_score'}).get_text() item.mvName = tag.find('img').get('alt') item.singer = tag.find('a',attrs={'class':'special'}).get_text() item.releasTime = tag.find('p',attrs={'class':'c9'}).get_text() items.append(item) self.sava(items,area)(3)随机获取UserAgents和PROXIES的函数 def getRandomProxy(self): return random.choice(resource.PROXIES) def getRandomHeader(self): return random.choice(resource.UserAgents)(4)上面两个函数在获取页面时调用 def getResponseContent(self,url): fakeHeaders = {'user-agent':self.getRandomHeader()} proxies = self.getRandomProxy() try: r = requests.get(url,headers = fakeHeaders,proxies = proxies,timeout = 30) r.raise_for_status() r.encoding = r.apparent_encoding time.sleep(1) return r.text # print(r.text) except: return 完整代码以及resource.py from bs4 import BeautifulSoup import requests import codecs import time import resource import random class Item(object): top_num = None score = None mvName = None singer = None releasTime = None class GetMvList(object): def __init__(self): self.urlBase = 'http://vchart.yinyuetai.com/vchart/trends?' self.areasDic = {'ML':'MainLand','HT':'HongKong&Taiwan','US':'Americ','KR':'Korea','JP':'Japan'} self.getUrls() def getUrls(self): areas = ['ML','HT','US','KR','JP'] pages =[str(i) for i in range(1,4)] for area in areas: urls =[] for page in pages: urlEnd = 'area='+area+'&page='+page url = self.urlBase+urlEnd urls.append(url) self.spider(area,urls) def getResponseContent(self,url): fakeHeaders = {'user-agent':self.getRandomHeader()} proxies = self.getRandomProxy() try: r = requests.get(url,headers = fakeHeaders,proxies = proxies,timeout = 30) r.raise_for_status() r.encoding = r.apparent_encoding time.sleep(1) return r.text # print(r.text) except: return def spider(self,area,urls): items = [] for url in urls: html = self.getResponseContent(url) if not html: continue soup = BeautifulSoup(html,'lxml') tags = soup.find_all('li',attrs={'name':'dmvLi'}) # tags = soup.find_all('li',attrs={'class','vitem J_li_toggle_date'}) for tag in tags: item = Item() item.top_num = tag.find('div',attrs={'class':'top_num'}).get_text() # if tag.find('h3',attrs={'class':'desc_score'}): # item.score = tag.find('h3',attrs={'class':'des_score'}).text() # else: # item.score = tag.find('h3',attrs={'class':'asc_score'}).get_text() item.mvName = tag.find('img').get('alt') item.singer = tag.find('a',attrs={'class':'special'}).get_text() item.releasTime = tag.find('p',attrs={'class':'c9'}).get_text() items.append(item) self.sava(items,area) # print(items[0]) def getRandomProxy(self): return random.choice(resource.PROXIES) def getRandomHeader(self): return random.choice(resource.UserAgents) def sava(self,items,area): fileName = 'mvTopList.txt' nowTime = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime()) with codecs.open(fileName,'w','utf8') as fp: fp.write('%s --------%s\r\n' %(self.areasDic.get(area),nowTime)) for item in items: fp.write('%s \t %s \t %s \t %s \r\n' %(item.top_num,item.releasTime,item.singer,item.mvName)) print('success') if __name__ == '__main__': GML = GetMvList()resource.py #!/usr/bin/env python #-*- coding: utf-8 -*- UserAgents = [ "Mozilla/4.0 (compatible;
