asp.net-mvc-4 – MVC 4中客户URL的自定义OpenIdClient

寄存器：

OAuthWebSecurity.RegisterClient(new StackExchangeOpenID());

类：

public class StackExchangeOpenID : OpenIdClient
{
    public StackExchangeOpenID()
        : base("stackexchange","https://openid.stackexchange.com")
    {

    }

    protected override Dictionary<string,string> GetExtraData(IAuthenticationResponse response)
    {
        FetchResponse fetchResponse = response.GetExtension<FetchResponse>();

        if (fetchResponse != null)
        {
            var extraData = new Dictionary<string,string>();
            extraData.Add("email",fetchResponse.GetAttributeValue(WellKnownAttributes.Contact.Email));
            extraData.Add("name",fetchResponse.GetAttributeValue(WellKnownAttributes.Name.FullName));
            return extraData;
        }

        return null;
    }
    protected override void OnBeforeSendingAuthenticationRequest(IAuthenticationRequest request)
    {
        var fetchRequest = new FetchRequest();
        fetchRequest.Attributes.AddRequired(WellKnownAttributes.Contact.Email);
        fetchRequest.Attributes.AddRequired(WellKnownAttributes.Name.FullName);
        request.AddExtension(fetchRequest);
    }
}

检索额外数据：

var result = OAuthWebSecurity.VerifyAuthentication();
result.ExtraData["email"];
result.ExtraData["name"];
