清除Asp.net Core中的所有cookie

Question

我正在Asp.net Core网站上工作，在我的退出链接中，我想删除所有当前的域Cookie。 当我与Asp.net MVC合作时，我尝试了这段代码

string[] myCookies = Request.Cookies.AllKeys;
foreach (string cookie in myCookies)
{
  Response.Cookies[cookie].Expires = DateTime.Now.AddDays(-1);
}

此代码在Asp.net Core中无效。 如何清除Asp.net Core中的所有cookie？

Answer 1

Request.Cookies是一个键值集合，其中Key是一个cookie名称。所以

foreach (var cookie in Request.Cookies.Keys)
{
    Response.Cookies.Delete(cookie);
}

请参阅：

public abstract class HttpRequest
{
    // Summary:
    //     /// Gets the collection of Cookies for this request. ///
    //
    // Returns:
    //     The collection of Cookies for this request.
    public abstract IRequestCookieCollection Cookies { get; set; }
    ...
 }

和IRequestCookieCollection是

public interface IRequestCookieCollection : IEnumerable<KeyValuePair<string, string>>, IEnumerable

Answer 2

试试这个：

//ASP.NET Core
foreach (string cookie in myCookies)
{
  Response.Cookies.Delete(cookie);  
}
