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.requestimport urllib.error#创建get方法def get(url): code=urllib.request.urlopen(url).code return codeif __name__ == '__main__':#设置一些基本属性 url = "http://shua..net.cn" 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..net.cn" #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..net.cn" 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 urllib2import timeitimport thread import timei = 0mylock = 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
