Django Cookies,我该怎么设置? [英] Django Cookies, how can I set them?
问题描述
我有一个网站根据访问者选择的位置
显示不同的内容。例如:用户输入55812作为zip。我知道
城市和区域lat / long。那就是向他们提供他们的内容相关的
给该地区。我的问题是如何将它存储在cookie中,以便
返回时不需要始终输入邮政编码?
I have a web site which shows different content based on a location the visitor chooses. e.g: User enters in 55812 as the zip. I know what city and area lat/long. that is and give them their content pertinent to that area. My question is how can I store this in a cookie so that when they return they are not required to always enter their zip code?
我看到它是如下:
- 根据他们的区域设置持久性cookie。
- 当他们返回读取cookie时,邮政编码。
- 根据Cookie中的邮政编码来收回内容。
似乎找到任何关于设置cookie的可靠信息。任何
帮助非常感谢。
I can't seem to find any solid information on setting a cookie. Any help is greatly appreciated.
推荐答案
这是一个帮助器设置一个持久的cookie:
This is a helper to set a persistent cookie:
import datetime
def set_cookie(response, key, value, days_expire = 7):
if days_expire is None:
max_age = 365 * 24 * 60 * 60 #one year
else:
max_age = days_expire * 24 * 60 * 60
expires = datetime.datetime.strftime(datetime.datetime.utcnow() + datetime.timedelta(seconds=max_age), "%a, %d-%b-%Y %H:%M:%S GMT")
response.set_cookie(key, value, max_age=max_age, expires=expires, domain=settings.SESSION_COOKIE_DOMAIN, secure=settings.SESSION_COOKIE_SECURE or None)
发送响应之前使用以下代码。
Use the following code before sending a response.
def view(request):
response = HttpResponse("hello")
set_cookie(response, 'name', 'jujule')
return response
