将login_hint与OpenID一起使用 [英] Use login_hint with OpenID

问题描述

我正在尝试将login_hint添加到用于Azure AD身份验证的OpenID登录请求中.

I am trying to add the login_hint to the OpenID sign-in request for Azure AD authentication.

将login_hint添加为属性对我来说不起作用:

It is not working for me, to add login_hint as a property:

var properties = new AuthenticationProperties();

properties.RedirectUri = "someCallbackUrl";

properties.Dictionary.Add("login_hint ", "SomeUsername");

AuthenticationManager.Challenge(properties, OpenIdConnectAuthenticationDefaults.AuthenticationType);

手动将login_hint添加到查询字符串...&login_hint=SomeUsername至少向我证明了这种功能的存在:-)

Adding the login_hint manually to the query string ...&login_hint=SomeUsername at least proves to me, that such functionality exists :-)

我了解，如果我要使用GoogleOAuth2AuthenticationProvider，则必须像那样覆盖自身.我尝试采用的方法是否需要类似的东西?

I understand that if I were to use GoogleOAuth2AuthenticationProvider that I would have to override itself like so. Is something similar needed for the approach that I am trying to take?

推荐答案

原来，我不得不将RedirectToIdentityProvider添加到app.UseOpenIdConnectAuthentication:

It turns out that I had to add the RedirectToIdentityProvider to app.UseOpenIdConnectAuthentication:

Notifications = new OpenIdConnectAuthenticationNotifications()
{
    RedirectToIdentityProvider = (context) =>
    {
        string login_hint = context.OwinContext.Authentication.AuthenticationResponseChallenge.Properties.Dictionary["login_hint"];
        context.ProtocolMessage.LoginHint = login_hint;
        return Task.FromResult(0);
     }
}
