[英].Net Core cookie will not be set
In .Net Core MVC project: I'm trying to set a simple cookie in the easiest way in my controller-action but can not get it to be persistent and show up in the browser.在 .Net Core MVC 项目中:我试图在我的控制器操作中以最简单的方式设置一个简单的 cookie,但无法使其持久化并显示在浏览器中。
My code:我的代码:
public IActionResult IndexPost()
{
var option = new CookieOptions();
option.Expires = DateTime.Now.AddMinutes(60);
Response.Cookies.Append(cookieName, "SomeCookieValue", option);
return View();
}
But in the browser (Chrome) I can't see it or even read it with:但是在浏览器(Chrome)中,我看不到它,甚至无法使用以下命令阅读它:
var cookieValue = Request.Cookies[cookieName];
( cookieName
is a variable set with name of the cookie) (
cookieName
是一个带有 cookie 名称的变量集)
If using Chrome extension "EditThisCookie" I can set it manually to ensure that Request.Cookies[cookieName]
actually works, so error is in the Append-cookie of my code somehow.如果使用 Chrome 扩展“EditThisCookie”,我可以手动设置它以确保
Request.Cookies[cookieName]
确实有效,所以错误在我的代码的 Append-cookie 中。
Starting from ASP.NET Core 2.1, the templates include a GDPR compliant configuration of your CookiePolicyOptions
in Startup.cs, namely:从ASP.NET 2.1的核心开始,该模板包括你的GDPR兼容配置
CookiePolicyOptions
在Startup.cs,即:
services.Configure<CookiePolicyOptions>(options =>
{
// This lambda determines whether user consent for non-essential cookies is needed for a given request.
options.CheckConsentNeeded = context => true;
options.MinimumSameSitePolicy = SameSiteMode.None;
});
The CheckConsentNeeded
option of true
will prevent any non-essential cookies from being sent to the browser (no Set-Cookie header) without the user's explicit permission. CheckConsentNeeded
选项为true
将防止在未经用户明确许可的情况下将任何非必要的 cookie 发送到浏览器(无 Set-Cookie 标头)。
You can either change this behaviour, or mark your cookie as essential by setting the IsEssential
property to true
when creating it:您可以更改此行为,或通过在创建时将
IsEssential
属性设置为true
来将您的 cookie 标记为必需:
var options = new CookieOptions
{
Expires = DateTime.Now.AddMinutes(60),
IsEssential = true
};
Response.Cookies.Append("rudeCookie", "I don't need no user to tell me it's ok.", options);
