爬取某知名网站的数据????
爬虫 + 骚操作 = 不讲武德 = 耗子尾汁
增加你的浏览量
github传送门: https://github.com/rzy0901/CSDN_visitor
需要安装的包
1️⃣
BeautifulSoup
2️⃣
urllib
安装方法:
百度 + 随缘
pip install xxx
代码函数介绍
1️⃣
def get_page_url_list(homepage_url, page_number):
for page in range(1, page_number + 1):
page_url_list.append("{0}/article/list/{1}".format(homepage_url, page))
print('page_url_list: ' + page_url_list.__str__())
- 功能:得到你的博客每一页的URL列表
- homepage_url: 博客主页的URL
- page_number: 博客的页数
- 注意!这个函数只适用于CSDN,别的博客可以自己观察一下换页之后博客主页的网址形式,再修改代码
2️⃣
def get_article_list(pageurl_list):
for page_url in pageurl_list:
response = requests.get(page_url, headers={'User-Agent': User_Agent[random.randint(0, len(User_Agent) - 1)],
'referer': 'http://blog.csdn.net'})
soup = BeautifulSoup(response.content, 'lxml')
h4 = soup.find_all("h4")
for h in h4:
if h is not None:
article_list.append(h.a["href"])
else:
pass
print("article_list" + article_list.__str__())
- 功能:得到你的博文的URL列表(全部)
- 输入为pageurl_list,即通过
get_page_url_list
得到的列表
3️⃣
def get_proxy_list():
for row in urlopen('http://proxylist.fatezero.org/proxy.list').readlines():
item = json.loads(row)
if item['type'] == 'http' and item['anonymity'] == 'high_anonymous' and item['response_time'] < 7:
proxy_list.append(item['host'] + ':' + str(item['port']))
print("proxy_list" + proxy_list.__str__())
功能:得到代理ip列表(目的为每隔一分钟更换代理ip,防止爬虫被发现)
需要*,所以直接用我跑出来的列表就行了。
当然也可以选择别的网站获取代理ip的列表。

运行案例
- 我应该已经挂机一段时间了,刷新一下网页界面:(可以看一下我电脑显示的时间)
大约每分钟14个浏览量(你有几篇博文,每分钟有几个浏览量,相当于每分钟拿一个新的ip把你的博文遍历访问一遍)。
备注
-
悠着点用,号没了。
-
csdn目前的机制一分钟内无论多少ip访问一篇博文,博文的最大访问量为1!!!(所以投机取巧是几乎不可能,更换ip意义在于防止爬虫被发现)
-
更换
User-Agent
以及代理ip防止爬虫被发现
