Question

我希望在用户成功登录后返回用户名，以显示在我的网络应用程序的右上角。我想用令牌返回的承载的json发送它。要使用ASP.NET Web API和Owin middlehawe生成令牌身份验证。

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

我希望返回就像这样

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

我曾尝试过声明，但那些并没有给出我想要的结果。

我曾尝试使用AuthenticationProperties但不起作用

 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.");
        }
    }

如何向owin bearer token返回的json添加更多值？。

Answer 1

在您检查有效性的同一个类上覆盖TokenEndpointResponse并返回其他字段，如下面的示例所示

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);
}

您可以通过将新项目添加到moreInfo.Dictionary来简单地完成此操作：

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

在ApplicationOAuthProvider.cs文件中，通过以下方法添加属性：

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);
        }
