模板方法
python也是一种面向对象的语言，所以在实现群发的时候，会登陆不同的网站，但是登陆的方法什么的不尽相同，所以这里想到的是模板方法。
模板方法模式：
应用特性：重复做相同逻辑的事情，但是具体细节不同的场景
结构特性：相同逻辑抽取至父类，具体细节留置子类。可以说是对逻辑的抽象
看一下代码：
#!/usr/bin/env python #encoding: utf-8 class template: def __init__(self): pass def logic(self): print 'do something before ....' print self.do_something_now() print 'do something after ....' def do_something_now(self): return None class apply_temp1(template): def __init__(self): pass def do_something_now(self): return 'apply 1' class apply_temp2(template): def __init__(self): pass def do_something_now(self): return 'apply 2' if '__main__' == __name__: obj1 = apply_temp1() obj2 = apply_temp2() obj1.logic() obj2.logic() print obj1.__class__ print obj2.__class__
得到结果如下：
然后看一下类图：
是不是很简单。
baidu登陆流程
想实现登陆baidu，使用firefox查看，可以看到如下图：
baidu HI登陆
baidu HI登陆源代码
# _*_ coding:utf-8 _*_ # name login_baidu.py import urllib,urllib2,httplib,cookielib def auto_login_hi(url,name,pwd): url_hi="http://passport.baidu.com/?login" #设置cookie cookie=cookielib.CookieJar() cj=urllib2.HTTPCookieProcessor(cookie) #设置登录参数 postdata=urllib.urlencode({'username':name,'password':pwd}) #生成请求 request=urllib2.Request(url_hi,postdata) #登录百度 opener=urllib2.build_opener(cj) f=opener.open(request) if(200==f.getcode()): print "登陆成功！" else: print "登录失败！" #print f.getcode() #打开百度HI空间页面 hi_html=opener.open(url) return hi_html if __name__=='__main__': name='用户名' password='密码' url='http://hi.baidu.com/ewayfly' h=auto_login_hi(url,name,password) print h.read()
登陆博客园
登录博客园的代码：
# _*_ coding:utf-8 _*_ import urllib,urllib2,httplib,cookielib def auto_login_cnblogs(url,name,pwd): url_hi="http://passport.cnblogs.com/login.aspx?ReturnUrl=http%3A%2F%2Fwww.cnblogs.com%2F" #设置cookie cookie=cookielib.CookieJar() cj=urllib2.HTTPCookieProcessor(cookie) #设置登录参数 postdata=urllib.urlencode({'username':name,'password':pwd}) #生成请求 request=urllib2.Request(url_hi,postdata) #登录百度 opener=urllib2.build_opener(cj) f=opener.open(request) if(200==f.getcode()): print "登陆成功！" else: print "登录失败！" #print f.getcode() hi_html=opener.open(url) return hi_html if __name__=='__main__': name='用户名' password='密码' url='http://www.cnblogs.com/skyme/' h=auto_login_cnblogs(url,name,password) print h.read()
登陆51CTO
登陆51CTO：
