用Python处理Cookie
第一次访问页面后，Server可将Cookie信息加入HTTP Header返回给浏览器，浏览器会自动将这些信息保存在本地；当再次访问相同域名时，浏览器将对应Cookie信息随请求一起发送，Server端可读取这些信息进行处理。
Cookie可设置过期时间，到期后由浏览器自动删除；
当我们要返回页面时，首先输出如下：
view plaincopyprint?
[*]print "Content-type: text/plain\n"
print "Content-type: text/plain\n"
它其实是一个HTTP Header, 连续碰到两个换行表示HTTP Header部分结束，剩余部分将被做为数据处理；
包含了Cookie后输出大致如下：
view plaincopyprint?
[*]print "Content-Type: text/html"
[*]
print "Set-Cookie: session=12345"
[*]
print # 多加一个换行表示HTTP Header部分结束
print "Content-Type: text/html"
print "Set-Cookie: session=12345"
print # 多加一个换行表示HTTP Header部分结束
代码：
setcookie.py
view plaincopyprint?
[*]#!/usr/bin/env python
[*]
[*]
import Cookie
[*]
import datetime
[*]
import random
[*]
[*]
expiration = datetime.datetime.now() + datetime.timedelta(days=30)
[*]cookie = Cookie.SimpleCookie()
[*]
cookie["session"] = random.randint(0,1000000000)
[*]
cookie["session"]["domain"] = "localhost"
[*]
cookie["session"]["path"] = "/"
[*]
cookie["session"]["expires"] = \
[*]
expiration.strftime("%a, %d-%b-%Y %H:%M:%S PST")
[*]
[*]
print "Content-type: text/plain"
[*]
print cookie.output()
[*]
[*]
print "Cookie set with: " + cookie.output()
#!/usr/bin/env python
import Cookie
import datetime
import random
expiration = datetime.datetime.now() + datetime.timedelta(days=30)
cookie = Cookie.SimpleCookie()
cookie["session"] = random.randint(0,1000000000)
cookie["session"]["domain"] = "localhost"
cookie["session"]["path"] = "/"
cookie["session"]["expires"] = \
expiration.strftime("%a, %d-%b-%Y %H:%M:%S PST")
print "Content-type: text/plain"
print cookie.output()
print "Cookie set with: " + cookie.output()
getcookie.py
view plaincopyprint?
[*]#!/usr/bin/env python
[*]
[*]
import Cookie
[*]
import os
[*]
[*]
print "Content-type: text/plain\n"
[*]
[*]
try:
[*]
cookie = Cookie.SimpleCookie(os.environ["HTTP_COOKIE"])
[*]
print "session = " + cookie["session"].value
[*]
except (Cookie.CookieError, KeyError):
[*]
print "session cookie not set!"
#!/usr/bin/env python

try:

print "session = " + cookie["session"].value
