博客群发（2）--实现登陆

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：
