Python制作刷网页流量工具_Python

准备

必须环境：

Python3

开始

先实现一个简单的版本，直接上代码：

				?

									import urllib.request

									import urllib.error

									#创建get方法

									def get(url):

									 code=urllib.request.urlopen(url).code

									 return code

									if __name__ == '__main__':

									#设置一些基本属性

									 url = "http://shua.jb51.net"

									 user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.63 Safari/537.36"

									 headers = {'User-Agent':user_agent}

									 req = urllib.request.Request(url, headers=headers)

									 #记录次数

									 i = 1

									 while 1: 

									   code = get(url)

									   print('访问:'+str(code))

									   i = i+1

简单粗暴，刷的只是 pv,ip 没变，容易被搜索引擎发现，下面我们来改进一下

增加代理功能

给 get 方法添加以下代码：

				?

									random_proxy = random.choice(proxies)

									proxy_support = urllib.request.ProxyHandler({"http":random_proxy})

									opener = urllib.request.build_opener(proxy_support)

									urllib.request.install_opener(opener)

修改一下主方法：

				?

									if __name__ == '__main__':

									 url = "http://shua.jb51.net"

									 #添加代理列表，可以自行去百度获取

									 proxies = ["124.88.67.22:80","124.88.67.82:80","124.88.67.81:80","124.88.67.31:80","124.88.67.19:80","58.23.16.240:80"]

									 user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.63 Safari/537.36"

									 headers = {'User-Agent':user_agent}

									 req = urllib.request.Request(url, headers=headers)

									 i = 1

									 while 1:

									   #添加参数

									   code = get(url,proxies)

									   print('第'+str(i)+'次代理访问:'+str(code))

									   i = i+1

这样差不多了，不过有个 bug ，如果页面打不开了或者代理失效了，程序就自动结束了，接下来我们添加异常处理功能

异常处理

定义 mail 方法，用来发邮件提醒

				?

									def mail(txt):

									 _user = "你的账号"

									 _pwd = "你的密码"

									 _to = "收件账号"

									 msg = MIMEText(txt, 'plain', 'utf-8')

									 #标题

									 msg["Subject"] = "代理失效！"

									 msg["From"] = _user

									 msg["To"] = _to

									 try:

									   #这里我用的qq邮箱

									   s = smtplib.SMTP_SSL("smtp.qq.com", 465)

									   s.login(_user, _pwd)

									   s.sendmail(_user, _to, msg.as_string())

									   s.quit()

									   print("Success!")

									 except smtplib.SMTPException as e:

									   print("Falied,%s" % e)

然后我们修改一下主方法：

				?

									if __name__ == '__main__':

									 url = "http://shua.jb51.net"

									 proxies = ["124.88.67.22:80","124.88.67.82:80","124.88.67.81:80","124.88.67.31:80","124.88.67.19:80","58.23.16.240:80"]

									 user_agent = "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.63 Safari/537.36"

									 headers = {'User-Agent':user_agent}

									 req = urllib.request.Request(url, headers=headers)

									 i = 1

									 while 1:

									   try:

									     code = get(url,proxies)

									     print('第'+str(i)+'次代理访问:'+str(code))

									     i = i+1

									   except urllib.error.HTTPError as e:

									     print(e.code)

									      #添加mail方法

									     mail(e.code)

									   except urllib.error.URLError as err:

									     print(err.reason)

									      #添加mail方法

									     mail(err.reason)

完成！

结语

代码只有短短的 50 行，程序还可以改进：

例如：代理列表自动获取，添加界面,扩展下多线程等等

最后给再给大家分享一个其他小伙伴的作品

				?

									import urllib2

									import timeit

									import thread 

									import time

									i = 0

									mylock = thread.allocate_lock()

									def test(no,r):

									  global i

									  url = 'http://blog.csdn.net'

									  for j in range(1,r):

									    req=urllib2.Request(url) 

									    req.add_header("User-Agent","Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0)") 

									    file = urllib2.urlopen(req)

									    print file.getcode();

									    mylock.acquire()

									    i+=1

									    mylock.release()  

									    print i;

									  thread.exit_thread()

									def fast():

									    thread.start_new_thread(test,(1,50))

									    thread.start_new_thread(test,(2,50)) 

									fast()

									time.sleep(15)

经测试，超过两个线程以上服务器就会出现503错误，所以2个线程刚好
