为了做好兼容性，只能选择兼容:冒号。

很简单，修改一下Cookie.Morsel
复制代码 代码如下:
#!/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
