asp.net-core – asp.net核心身份中的多个&SubDomain的cooki

app.UseIdentity();

app.UseCookieAuthentication不是解决方案.

我终于通过实现ICookieManager找到了我的解决方案.

这是我的解决方案：

在Startup.cs中：

services.AddIdentity<ApplicationUser,IdentityRole>(options =>
        {
            options.Password.RequireDigit = false;
            options.Password.RequiredLength = 5;
            options.Password.RequireNonAlphanumeric = false;
            options.Password.RequireLowercase = false;
            options.Password.RequireUppercase = false;
            options.Cookies.ApplicationCookie.CookieManager = new CookieManager(); //Magic happens here
        }).AddEntityFrameworkStores<ApplicationDbContext>()
            .AddDefaultTokenProviders();

现在我在一个叫做CookieManager.cs的类中：

public class CookieManager : ICookieManager
{
    #region Private Members

    private readonly ICookieManager ConcreteManager;

    #endregion

    #region Prvate Methods

    private string RemoveSubdomain(string host)
    {
        var splitHostname = host.Split('.');
        //if not localhost
        if (splitHostname.Length > 1)
        {
            return string.Join(".",splitHostname.Skip(1));
        }
        else
        {
            return host;
        }
    }

    #endregion

    #region Public Methods

    public CookieManager()
    {
        ConcreteManager = new ChunkingCookieManager();
    }

    public void AppendResponseCookie(HttpContext context,string key,string value,CookieOptions options)
    {

        options.Domain = RemoveSubdomain(context.Request.Host.Host);  //Set the Cookie Domain using the request from host
        ConcreteManager.AppendResponseCookie(context,key,value,options);
    }

    public void DeleteCookie(HttpContext context,CookieOptions options)
    {
        ConcreteManager.DeleteCookie(context,options);
    }

    public string GetRequestCookie(HttpContext context,string key)
    {
        return ConcreteManager.GetRequestCookie(context,key);
    }

    #endregion
