让python的Cookie.py模块支持冒号做key的方法

为了做好兼容性，只能选择兼容:冒号。

很简单，修改一下Cookie.Morsel

#!/usr/bin/python 
# -*- coding: utf-8 -*- 
"""MorselHook, fix Cookie.CookieError: Illegal key value: ys-tab:entrance:e 
""" import Cookie 
import string 
_Morsel = Cookie.Morsel 
class MorselHook(_Morsel): 
""" 
>>> import inspect 
>>> (inspect.getargspec(MorselHook.set)[3])[0] 
"abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789!#$%&'*+-.^_`|~:" 
>>> cookie = Cookie.SimpleCookie() 
>>> cookie.load("ys-tab:entrance:e=abc; webpy_session_id=75eb60dcc83e2d902146af0bb7f47afe61fbd2b2") 
>>> print cookie 
Set-Cookie: webpy_session_id=75eb60dcc83e2d902146af0bb7f47afe61fbd2b2; 
Set-Cookie: ys-tab:entrance:e=abc; 
""" 
def set(self, key, val, coded_val, LegalChars=Cookie._LegalChars+':', idmap=string._idmap, translate=string.translate): 
return super(MorselHook, self).set(key, val, coded_val, LegalChars, idmap, translate) 
Cookie.Morsel = MorselHook 
# 在你需要使用到Cookie的地方先让上面的代码执行一遍
