博客群發（2）--實現登陸

模板方法

python也是一種面向對象的語言，所以在實現群發的時候，會登陸不同的網站，但是登陸的方法什么的不盡相同，所以這里想到的是模板方法。

模板方法模式：

應用特性：重復做相同邏輯的事情，但是具體細節不同的場景

結構特性：相同邏輯抽取至父類，具體細節留置子類。可以說是對邏輯的抽象

看一下代碼：

#!/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__

得到結果如下：

然后看一下類圖：

是不是很簡單。

baidu登陸流程

想實現登陸baidu，使用firefox查看，可以看到如下圖：

baidu HI登陸

baidu HI登陸源代碼

# _*_ 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"
    #設置cookie
    cookie=cookielib.CookieJar()
    cj=urllib2.HTTPCookieProcessor(cookie)
    #設置登錄參數
    postdata=urllib.urlencode({'username':name,'password':pwd})
    #生成請求
    request=urllib2.Request(url_hi,postdata)
    #登錄百度
    opener=urllib2.build_opener(cj)
    f=opener.open(request)
    if(200==f.getcode()):
        print "登陸成功！"
    else:
        print "登錄失敗！"
    #print f.getcode()
    #打開百度HI空間頁面
    hi_html=opener.open(url)
    return hi_html

    url='http://hi.baidu.com/ewayfly'
    h=auto_login_hi(url,name,password)
    print h.read()

登陸博客園

登錄博客園的代碼：
