Django Cookies，我该怎么设置？(Django Cookies, how can I set them?)

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。 我知道什么城市和地区lat / long。 那就是并且给他们他们与该地区有关的内容。 我的问题是如何将它存储在cookie中，以便在返回时不需要始终输入邮政编码？

我看到如下：

根据他们的区域设置持久性cookie。 当他们返回阅读cookie，抓住邮政编码。 根据Cookie中的邮政编码返回内容。

我似乎找不到有关设置Cookie的任何可靠信息。 任何帮助是极大的赞赏。

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?

I see it as follows:

Set persistent cookie based on their area. When they return read cookie, grab zipcode. Return content based on the zip code in their cookie.

I can't seem to find any solid information on setting a cookie. Any help is greatly appreciated.

这是一个帮助器设置一个持久的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，请使用以下代码。

def view(request): response = HttpResponse("hello") set_cookie(response, 'name', 'jujule') return response

更新 ：检查@Peter下面的内置解决方案： https ： //stackoverflow.com/a/5575578/174027

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)

Use the following code before sending a response.

def view(request): response = HttpResponse("hello") set_cookie(response, 'name', 'jujule') return response
