這次比2345電影那個多了一個resource.py文件,里面包含UserAgents,PROXIES,這樣我們在爬取時可以寫一個函數,隨機從這兩項中選取,以此繞開反爬蟲.

1.目標:音悅臺-V榜-MV作品榜
2.所使用的庫:

from bs4 import BeautifulSoup import requests import codecs import time import resource import random

測試環境 Python 3.6.0
3.目標鏈接
http://vchart.yinyuetai.com/vchart/trends?area=ML&page=2
通過點擊圖中紅圈部分觀察后,發現area=后面的和&page=后面的會變化

(1)寫一個url地址拼接的函數
這樣urls列表中就保存了我們想要的鏈接地址

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='+pageurl = self.urlBase+urlEndurls.append(url)self.spider(area,urls)

(2)我們再來看一些spider()函數

def spider(self,area,urls):items = []for url in urls:html = self.getResponseContent(url)if not html:continuesoup = 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)隨機獲取UserAgents和PROXIES的函數

def getRandomProxy(self):return random.choice(resource.PROXIES)def getRandomHeader(self):return random.choice(resource.UserAgents)

(4)上面兩個函數在獲取頁面時調用

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_encodingtime.sleep(1)return r.text# print(r.text)except:return

完整代碼以及resource.py
