Django Cookies，我该如何设置它们? [英] Django Cookies, how can I set them?

问题描述

我有一个根据位置显示不同内容的网站访客选择.例如:用户输入 55812 作为 zip.我知道什么城市和地区纬度/经度.也就是说，给他们相关的内容到那个区域.我的问题是如何将其存储在 cookie 中，以便当他们返回时，他们不需要总是输入邮政编码?

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?

我是这样看的:

1. 根据他们的区域设置持久性 cookie.
2. 当他们返回读取的 cookie 时，获取邮政编码.
3. 根据 cookie 中的邮政编码返回内容.

我似乎找不到任何关于设置 cookie 的可靠信息.任何非常感谢帮助.

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

这是一个设置持久性cookie的助手:

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,
    )

在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
