Retrieving client name in IdentityServer4 and ASP.NET Core

问题

The dbo.Clients table in the IdentityServer database contains both ClientId and ClientName, however requesting a client credentials token doesn't include the client name in the token.

Is there a way to either retrieve client information from IdentityServer given the client id, or request that the client name be added to the token?

回答1:

You can add them dynamically using a custom token request validator :

public class ClaimClientsUpdated : ICustomTokenRequestValidator
{
    public Task ValidateAsync(CustomTokenRequestValidationContext context)
    {
        context.Result.ValidatedRequest.Client.AlwaysSendClientClaims = true;
        context.Result.ValidatedRequest.ClientClaims.Add(new Claim("name", context.Result.ValidatedRequest.Client.ClientName));

       return Task.FromResult(0);
    }
}

services.AddTransient<ICustomTokenRequestValidator, ClaimClientsUpdated>();

It will add prefix "client_" to custom claims , so claim will be "client_name": "value" in access token .

You can add information about the client in general by adding claims to the ClientClaims table. E.g. Type = Name, Value = MyCustomName

Which is added as claim (assuming prefix client_):

"client_Name": "MyCustomName"

This will allow you to add information about the client without having to add or change code.

The drawback for the client name is that you'll have to add a claim with redundant information, as Clients.ClientName is not the source. The advantage is that it's configuration only.
