向不记名令牌 json 添加更多值

Question

I want to return the user name after they logged in successfully to display on the upper right corner on my web app. I want to send it with the json that bearer the token returns. To generate the token authentication I'm using ASP.NET web API and Owin middlehawe.

{   
  "access_token": "blah",
  "token_type": "bearer",
  "expires_in": 599
}

I want the return to be like this

{   
  "access_token": "blah",
  "token_type": "bearer",
  "expires_in": 599,
  "displayusername":"Hi Mundo"
}

I have tried claims but those are not giving the result I want.

I have tried to use AuthenticationProperties but doesn't work

 public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
    {
        context.OwinContext.Response.Headers.Add("Access-Control-Allow-Origin", new[] { "*" });
        if (validation works)
        {
           // add claims

            var moreInfo = new AuthenticationProperties(new Dictionary<string, string> { { "username", "Don"}, { "Department","MIS"} });

            var ticket = new AuthenticationTicket(identity, moreInfo);
            context.Validated(ticket);
        }
        else
        {
            context.SetError("invalid_grant", "The user name or password is incorrect.");
        }
    }

How do I add more values to the json that the owin bearer token returns?.

Answer 1

Override TokenEndpointResponse on same class you are checking for validity and return additional field as shown in sample below

public override Task TokenEndpointResponse(OAuthTokenEndpointResponseContext context)
{
    string thisIsTheToken = context.AccessToken;
    //add user Id and status as additional response parameter
    context.AdditionalResponseParameters.Add("displayusername", "Hi Mundo");
    context.AdditionalResponseParameters.Add("Status", "1");     
    return base.TokenEndpointResponse(context);
}

Answer 2

you can simple do it by Add new item to moreInfo.Dictionary :

moreInfo.Dictionary.Add("username", user.UserName);
moreInfo.Dictionary.Add("Department","MIS");

Answer 3

in ApplicationOAuthProvider.cs file add your properties in below method :

public override async Task GrantResourceOwnerCredentials(OAuthGrantResourceOwnerCredentialsContext context)
            {
              
                AuthenticationProperties properties = CreateProperties(user.UserName,user.FirstName,user.LastName);
              
            }




public static AuthenticationProperties CreateProperties(string userName,string FirstName,string LastName)
        {
            IDictionary<string, string> data = new Dictionary<string, string>
            {
                { "userName", userName },
                { "FirstName", FirstName },
                { "LastName", LastName },
            };
            return new AuthenticationProperties(data);
        }
