没有指定authenticationScheme，也没有找到DefaultChallengeScheme Cookies身份验证 [英] No authenticationScheme was specified, and there was no DefaultChallengeScheme found Cookies Authentication

问题描述

我正在使用以下代码在使用cookie的ASP.NET Core 2.0中进行身份验证

I am using the below code for authentication in ASP.NET Core 2.0 using cookies

services
    .AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)
    .AddCookie("MyCookieMiddlewareInstance", options =>
    {
        options.AccessDeniedPath = new PathString("/Account/Login");
        options.LoginPath = new PathString("/Account/Login");
        options.LogoutPath = new PathString("/Account/LogOff");
    });

我遇到错误:

未指定authenticationScheme，也未找到DefaultChallengeScheme

No authenticationScheme was specified, and there was no DefaultChallengeScheme found

Cookie设置如下:

The cookies setup is below:

var claims = new List<Claim>
{
    new Claim(ClaimTypes.NameIdentifier, userId.ToString()),
    new Claim(ClaimTypes.Name, userName)
};

var identity = new ClaimsIdentity(claims, "Forms");
identity.AddClaim(new Claim(ClaimTypes.Role, "ADMIN"));
var principal = new ClaimsPrincipal(identity);
HttpContext.Authentication.SignInAsync("MyCookieMiddlewareInstance", principal, new AuthenticationProperties
{
    IsPersistent = isPersistent,
    ExpiresUtc = DateTime.UtcNow.AddYears(1)
});

我做了一些研究，但没有找到解决方案.这是指向文档的链接我用过:

I did some research and didn't find the solution. Here is a link to the doc I used:

任何人都可以让我知道如何解决此问题吗?

Can anyone please let me know how can I resolve this issue?

推荐答案

authenticationBuilder.AddCookie("MyCookieMiddlewareInstance", …)

这将使用身份验证方案名称"MyCookieMiddlewareInstance"注册一个cookie身份验证处理程序.因此，无论何时使用Cookie身份验证方案，都需要使用该确切名称，否则将找不到该方案.

This registers a cookie authentication handler using the authentication scheme name "MyCookieMiddlewareInstance". So whenever you are referring to the cookie authentication scheme, you will need to use that exact name, otherwise you will not find the scheme.

但是，在AddAuthentication调用中，您使用的是不同的方案名称:

However, in the AddAuthentication call, you are using a different scheme name:

services.AddAuthentication(CookieAuthenticationDefaults.AuthenticationScheme)

这会将具有恒定值"Cookies"的CookieAuthenticationDefaults.AuthenticationScheme注册为默认身份验证方案.但是，从未注册具有该名称的方案！相反，只有"MyCookieMiddlewareInstance".

This registers the CookieAuthenticationDefaults.AuthenticationScheme, which has the constant value "Cookies", as the default authentication scheme. But a scheme with that name is never registered! Instead, there’s only a "MyCookieMiddlewareInstance".

因此解决方案是为两个调用简单地使用相同的名称.您也可以只使用默认值，并删除显式名称.如果您没有多个方案并且需要更多控制权，那么实际上就不需要显式设置其名称.

So the solution is to simply use the same name for both calls. You can also just use the defaults, and remove the explicit names; if you don’t have multiple schemes and need more control, there isn’t really a need to explicitly set their names.
