MVC 5使用身份验证模式的外部身份验证=表格 [英] MVC 5 External authentication with authentication mode=Forms

问题描述

我正在关注更改为authentication mode="Forms"，它将停止工作.

I'm following this tutorial to create a simple MVC 5 app with external authentication. It's working fine, but, if I change the authentication mode="None" to authentication mode="Forms" it stops working.

我在以下位置上空了

await HttpContext.GetOwinContext().Authentication.GetExternalLoginInfoAsync()

我读了很多有关在重定向时禁止FormsAuthentication的内容.我不知道这是否是正确的路径，但我尝试安装此

I'm reading a lot about something to suppress FormsAuthentication on redirect. I don't know if it's the right path, but I tried to install this nuget packet and the problem is still there.

那么，为什么每次更改身份验证模式时我都为空?

So, why I'm getting null everytime I change the authentication mode?

推荐答案

通过将Response.SuppressFormsAuthenticationRedirect = true添加到ChallengeResult类中，我可以使它正常工作(OWIN和FormsAuthentication).

I was able to get this working (OWIN and FormsAuthentication) by adding Response.SuppressFormsAuthenticationRedirect = true to the ChallengeResult Class.

如果您正在学习本教程，则代码如下:

If you are following the tutorial, here is the code:

public class ChallengeResult : HttpUnauthorizedResult
{
    public ChallengeResult(string provider, string redirectUri)
        : this(provider, redirectUri, null)
    {
    }

    public ChallengeResult(string provider, string redirectUri, string userId)
    {
        LoginProvider = provider;
        RedirectUri = redirectUri;
        UserId = userId;
    }

    public string LoginProvider { get; set; }
    public string RedirectUri { get; set; }
    public string UserId { get; set; }

    public override void ExecuteResult(ControllerContext context)
    {
        // this line did the trick
        context.RequestContext.HttpContext.Response.SuppressFormsAuthenticationRedirect = true;

        var properties = new AuthenticationProperties() { RedirectUri = RedirectUri };
        if (UserId != null)
        {
            properties.Dictionary[XsrfKey] = UserId;
        }

        context.HttpContext.GetOwinContext().Authentication.Challenge(properties, LoginProvider);
    }
}
