asp.net-mvc – Chrome丢失了cookie

我也在这里编码和解码.但你可以通过删除编码和解码并传递正常来存储它.这是我的代码

在这里,我把我的类与静态方法.我使用HttpSecureCode与Encode和Decode使用机器密钥加密.在这种情况下默认情况下可能不可用.你可以直接把价值放在一边.

如果您非常关注使用HttpSecureCode,请使用此link来构建您的课程

public class CookieStore
{
    public static void SetCookie(string key,string value,TimeSpan expires)
    {
        HttpCookie encodedCookie = HttpSecureCookie.Encode(new HttpCookie(key,value));

        if (HttpContext.Current.Request.Cookies[key] != null)
        {
            var cookieOld = HttpContext.Current.Request.Cookies[key];
            cookieOld.Expires = DateTime.Now.Add(expires);
            cookieOld.Value = encodedCookie.Value;
            HttpContext.Current.Response.Cookies.Add(cookieOld);
        }
        else
        {
            encodedCookie.Expires = DateTime.Now.Add(expires);
            HttpContext.Current.Response.Cookies.Add(encodedCookie);
        }
     }
    public static string GetCookie(string key)
    {
        string value = string.Empty;
        HttpCookie cookie = HttpContext.Current.Request.Cookies[key];

        if (cookie != null)
        {
            // For security purpose,we need to encrypt the value.
            HttpCookie decodedCookie = HttpSecureCookie.Decode(cookie);
            value = decodedCookie.Value;
        }
        return value;
    }

}

使用这些,您可以轻松地在cookie中存储值,并在需要时获取值

使用这些方法很简单

设置Cookie：

CookieStore.SetCookie("currency","GBP",TimeSpan.FromDays(1)); // here 1 is no of days for cookie to live

对于获取Cookie：

string currency= CookieStore.GetCookie("currency");
