HttpClient调用IdentityServer4获取Token并调用接口

using System;
using System.Net.Http;
using IdentityModel.Client;

namespace ClientCredential
{
    class Program
    {
        static void Main(string[] args)
        {
            try
            {
                new Program().GetAsync();
            }
            catch (Exception ex)
            {
                System.Console.WriteLine(ex.Message);
            }

            Console.ReadKey();

        }

        public async void GetAsync()
        {
            var diso = await DiscoveryClient.GetAsync("http://localhost:5003");
            if (diso.IsError)
            {
                System.Console.WriteLine("diso.Error");
            }
            var tokenClient = new TokenClient(diso.TokenEndpoint, "client", "secrt");
            var tokenResponse = await tokenClient.RequestClientCredentialsAsync("api");
            if (tokenResponse.IsError)
            {
                System.Console.WriteLine(tokenResponse.Error);
            }
            else
            {
                System.Console.WriteLine(tokenResponse.Json);
            }

            using (var httpClient = new HttpClient())
            {
                httpClient.SetBearerToken(tokenResponse.AccessToken);
                var response = await httpClient.GetAsync("http://localhost:5001/api/values");
                if (response.IsSuccessStatusCode)
                {
                    System.Console.WriteLine(await response.Content.ReadAsStringAsync());
                }
            }

        }
    }
}
