2.找了一个获取代理ip的网址www.kuaidaili.com/ops/proxyli…3.测试代理ip是否有效的网址’http://icanhazip.com’4.下面代码是爬取信息所用的时间。# 计算运行所需的时间
def run_time(func):
def wrapper(*args, **kw):
start = time.time()
func(*args, **kw)
end = time.time()
print(‘running’, end-start, ‘s’)
return wrapper
复制代码
5.定义一些常量def __init__(self):

self.getProxy = ‘http://www.xicidaili.com/nn/1/’

6.爬取代理ip的信息放入队列里，方便爬取豆瓣信息时获取。def get_proxy(self):
url = self.getProxy
try:
# random.choice(self.user_agent)是随机获取一个用户代理。
# 因为免费的代理ip不稳定所以这里设置self.notproxy，如果稳定的话就换成self.proxy1
r = requests.get(url, headers={‘User-Agent': random.choice(self.user_agent)}, proxies=self.notproxy,verify=False,timeout=1)
r.encoding = ‘utf-8′
if (r.status_code == 200):
soup = BeautifulSoup(r.content, ‘html.parser’)
ip_list = soup.find_all(‘table’, id=’ip_list’)
if(len(ip_list)):
tr_list = ip_list[0].find_all(‘tr’)[1:10]
for i in tr_list:
td_list = i.find_all(‘td’)
temp = td_list[5].text + ‘,’ + td_list[1].text + ‘:’ +td_list[2].text
self.IPQurl.put(temp)
return True
else:
print(‘页面查询不到该id’)
return False
else:
print(‘无法获取代理ip’)
return False
except Exception as e:
print(‘获取代理ip出错–‘,str(e))
return False
7.设置代理ip的值def set_proxy(self):
if self.IPQurl.empty():
if self.get_proxy():
arr = self.IPQurl.get().split(‘,’)
arr1 = self.IPQurl.get().split(‘,’)
if arr[0].find(‘HTTPS’) == -1:
self.proxy = {arr[0].lower(): ‘http://’+arr[1]}
else:
self.proxy = {arr[0].lower(): ‘https://’+arr[1]}
if arr1[0].find(‘HTTPS’) == -1:
self.proxy1 = {arr1[0].lower(): ‘http://’+arr1[1]}
else:
self.proxy1 = {arr1[0].lower(): ‘https://’+arr1[1]}
else:
self.proxy = {}
self.proxy1 = {}
else:
arr = self.IPQurl.get().split(‘,’)
if arr[0].find(‘HTTPS’) == -1:
self.proxy = {arr[0].lower(): ‘http://’ + arr[1]}
else:
self.proxy = {arr[0].lower(): ‘http://’ + arr[1]}
8.开始爬取豆瓣top250数据的链接。def parse_first(self, url):
print(‘crawling,parse_first’, url)
self.set_proxy()
try:
# 因为免费的代理ip不稳定所以这里设置self.notproxy，如果稳定的话就换成self.proxy
r = requests.get(url, headers={‘User-Agent': random.choice(self.user_agent)},proxies=self.notproxy,verify=False,timeout=5)
r.encoding = ‘utf-8′
if r.status_code == 200:
soup = BeautifulSoup(r.content, ‘html.parser’)
# 每一页爬数据条数
movies = soup.find_all(‘div’, class_=’info’)[:self.item_num]
for movie in movies:
url = movie.find(‘div’, class_=’hd’).a[‘href’]
self.qurl.put(url)
nextpage = soup.find(‘span’, class_=’next’).a
if nextpage:
nexturl = self.start_url + nextpage[‘href’]
self.parse_first(nexturl)
else:
self.first_running = False
else:
print(‘ip被屏蔽’)
self.proxy = {}
self.proxy1 = {}
self.first_running = False
except Exception as e:
self.proxy = {}
self.proxy1 = {}
self.first_running = False
print(‘代理ip代理失败–‘,str(e))
9.是时候爬取真正的信息了，爬取的信息写入数组里面。def parse_second(self):
# 停止触发的条件是self.first_running = False和self.qurl为空。
while self.first_running or not self.qurl.empty():
if not self.qurl.empty():
url = self.qurl.get()
print(‘crawling,parse_second’, url)
self.set_proxy()
try:
r = requests.get(url,headers={‘User-Agent': random.choice(self.user_agent)},proxies=self.notproxy,verify=False,timeout=5)
r.encoding = ‘utf-8′
if r.status_code == 200:
soup = BeautifulSoup(r.content, ‘html.parser’)
mydict = {}
mydict[‘url’] = url
title = soup.find(‘span’, property = ‘v:itemreviewed’)
mydict[‘title’] = title.text if title else None
duration = soup.find(‘span’, property = ‘v:runtime’)
mydict[‘duration’] = duration.text if duration else None
addtime = soup.find(‘span’, property = ‘v:initialReleaseDate’)
mydict[‘addtime’] = addtime.text if addtime else None
average = soup.find(‘strong’, property = ‘v:average’)
mydict[‘average’] = average.text if average else None
imgSrc = soup.find_all(‘div’, id=’mainpic’)[0].img[‘src’]
mydict[‘imgSrc’] = imgSrc if imgSrc else None
mydict[‘play’] = []
ul = soup.find_all(‘ul’, class_=’bs’)
if len(ul):
li = ul[0].find_all(‘li’)
for i in li:
obj = {
‘url':urllib.parse.unquote(i.a[‘href’].replace(‘https://www.douban.com/link2/?url=’,”)),
‘text':i.a.text.replace(‘ ‘, ”).replace(‘\n’,”)
}
mydict[‘play’].append(obj)
self.data.append(mydict)
# 线程随机休眠
time.sleep(random.random() * 5)
else:
print(‘ip被屏蔽’)
except Exception as e:
self.proxy = {}
self.proxy1 = {}
print(‘代理ip代理失败2–‘,str(e))
10.真正要运行的函数是这里。#这个是函数运行完所需要的时间
@run_time
def run(self):
ths = []
th1 = Thread(target=self.parse_first, args=(self.start_url, ))
th1.start()
ths.append(th1)
for _ in range(self.thread_num):
th = Thread(target=self.parse_second,)
th.setDaemon(True)
th.start()
ths.append(th)
for th in ths:
# 等待线程终止
th.join()
s = json.dumps(self.data, ensure_ascii=False, indent=4)
with open(‘top250.json’, ‘w’, encoding=’utf-8′) as f:
f.write(s)
print(‘Data crawling is finished.’)
11.开始运行啦。if __name__ == ‘__main__':
Spider().run()
12.最后运行完啦。这里只爬取了50条数据，用了20秒。爬取出来的数据格式是这样子的。13.最后附上所有代码，希望能帮到你。import time

import random
