如何在 C# 中创建非持久（在内存中）http cookie？

发布于 2024-10-08 07:49:53 字数 318 浏览 0 评论 0原文

我希望我的 cookie 在用户关闭浏览器时消失——我已经设置了一些看起来很有希望的属性，但即使关闭整个浏览器，我的 cookie 也会弹出来。

HttpCookie cookie = new HttpCookie("mycookie", "abc");
cookie.HttpOnly = true; //Seems to only affect script access
cookie.Secure = true; //Seems to affect only https transport

为了实现内存 cookie，我缺少什么属性或方法调用？

原文

I want my cookie to disappear when the user closes their brower-- I've already set some promising looking properties, but my cookies pop back to live even after closing the entire browser.

HttpCookie cookie = new HttpCookie("mycookie", "abc");
cookie.HttpOnly = true; //Seems to only affect script access
cookie.Secure = true; //Seems to affect only https transport

What property or method call am I missing to achieve an in memory cookie?

cookie.Expires = DateTime.MinValue;

一旦浏览器关闭，该 cookie 就会过期。

cookie.Expires = DateTime.MinValue;

this cookie will expire, as soon as the browser is closed.

浏览会话结束后，没有明确设置过期时间的 Cookie 将自动消失。

现在，“浏览会话”对于不同的浏览器有不同的含义。对于某些浏览器来说，这意味着浏览器的每个实例都已关闭。对于某些人来说，这仅意味着相关选项卡或原始浏览器已关闭。

在测试中，请确保在重新打开浏览器以查找 cookie 之前关闭浏览器的每个实例。如果您仍然遇到问题，请发布浏览器名称和版本。

如果您没有设置 Cookie.Expires 属性，则 cookie 将设置为在浏览器会话结束时过期。

如果出现以下情况，Cookie 不会在浏览器关闭时被销毁 取自此处

 HttpCookie cookie = new HttpCookie(name);
 cookie.Value = value;
 cookie.Expires = Convert.ToDateTime(“12/12/2008″);  //*difference is here*//
 Response.Cookies.Add(cookie);}

如果出现以下情况，Cookie 将在浏览器关闭时丢失

     HttpCookie cookie = new HttpCookie(name);
     cookie.Value = value;
     Response.Cookies.Add(cookie);}

Cookie Will not be destroy on browser close if Taken from here

 HttpCookie cookie = new HttpCookie(name);
 cookie.Value = value;
 cookie.Expires = Convert.ToDateTime(“12/12/2008″);  //*difference is here*//
 Response.Cookies.Add(cookie);}

Cookie will be lost on browser close if

     HttpCookie cookie = new HttpCookie(name);
     cookie.Value = value;
     Response.Cookies.Add(cookie);}

在浏览器打开的情况下处理非持久 cookie 超时的最佳方法是添加超时键值。下面的代码用于登录用户 ID 键值和加密（不包括）安全性，以实现浏览器兼容性。我不使用表单身份验证。

HttpCookie cookie = new HttpCookie(name);
cookie.Values["key1"] = value;
cookie.Values["key2"] = DateTime.Now.AddMinutes(70).ToString(); 
                             //timeout 70 minutes with browser open
cookie.Expires = DateTime.MinValue;
cookie.Domain = ConfigurationManager.AppSettings["website_domain"];
System.Web.HttpContext.Current.Response.Cookies.Add(cookie);

检查 cookie 键值使用时：

try
{

DateTime dateExpireDateTime;
dateExpireDateTime = DateTime.Parse(HttpContext.Current.Request.Cookies[name]["key2"]);

if (DateTime.Now > dateExpireDateTime)
{
//cookie key value timeout code
}
else
{
//reset cookie
}

catch
{
//clear cookie and redirect to log in page
}

我发现使用表单身份验证和 Google Chrome 存在兼容性问题。

The best way to handle non-persistent cookies timeout with the browser open is add a key value for timeout. The code below is used for a log in user id key value and encryption(not included) security for browser compatibility. I do not use forms authentication.

HttpCookie cookie = new HttpCookie(name);
cookie.Values["key1"] = value;
cookie.Values["key2"] = DateTime.Now.AddMinutes(70).ToString(); 
                             //timeout 70 minutes with browser open
cookie.Expires = DateTime.MinValue;
cookie.Domain = ConfigurationManager.AppSettings["website_domain"];
System.Web.HttpContext.Current.Response.Cookies.Add(cookie);

When checking the cookie key value use:

try
{

DateTime dateExpireDateTime;
dateExpireDateTime = DateTime.Parse(HttpContext.Current.Request.Cookies[name]["key2"]);

if (DateTime.Now > dateExpireDateTime)
{
//cookie key value timeout code
}
else
{
//reset cookie
}

catch
{
//clear cookie and redirect to log in page
}

I have found compatibility issues using forms authentication and Google Chrome.
