本文給大家分享的是一個使用python製作的,可以實現刷網頁流量的小工具,並給大家附上了詳細代碼,有需要的小夥伴可以參考下
準備
必須環境:
Python3
開始
先實現一個簡單的版本,直接上代碼:
import urllib.requestimport urllib.error#建立get方法def get(url): code=urllib.request.urlopen(url).code return codeif __name__ == '__main__':#設定一些基本屬性 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) #記錄次數 i = 1 while 1: code = get(url) print('訪問:'+str(code)) i = i+1
簡單粗暴,刷的只是 pv,ip 沒變,容易被搜尋引擎發現,下面我們來改進一下
增加代理功能
給 get 方法添加以下代碼:
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,可以自行去百度擷取 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: #添加參數 code = get(url,proxies) print('第'+str(i)+'次代理訪問:'+str(code)) i = i+1
這樣差不多了,不過有個 bug ,如果頁面打不開了或者代理失效了,程式就自動結束了,接下來我們添加異常處理功能
異常處理
定義 mail 方法 ,用來發寄件提醒
def mail(txt): _user = "你的帳號" _pwd = "你的密碼" _to = "收件帳號" msg = MIMEText(txt, 'plain', 'utf-8') #標題 msg["Subject"] = "代理失效!" msg["From"] = _user msg["To"] = _to try: #這裡我用的qq郵箱 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)
然後我們修改一下主方法:
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)+'次代理訪問:'+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!
結語
代碼只有短短的 50 行,程式還可以改進:
例如:代理列表自動擷取,添加介面,擴充下多線程等等
最後給再給大家分享一個其他小夥伴的作品
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)
經測試,超過兩個線程以上伺服器就會出現503錯誤,所以2個線程剛好
