ASP.NET Core分布式项目实战（第三方ClientCredential模式调用）

任务10：第三方ClientCredential模式调用

创建一个控制台程序

dotnet new console --name ThirdPartyDemo

添加 Nuget 包：IdentityModel

添加之后还原

dotnet restore

Client

using System;
using System.Net.Http;
using System.Threading.Tasks;
using IdentityModel.Client;
using Newtonsoft.Json.Linq;

namespace ThirdPartyDemo
{
    class Program
    {
        static async Task Main(string[] args)
        {
            // discover endpoints from metadata
            var client = new HttpClient();
            var disco = client.GetDiscoveryDocumentAsync("http://localhost:5000").Result;
            if (disco.IsError)
            {
                Console.WriteLine(disco.Error);
                return;
            }

            // request token
            var tokenResponse = await client.RequestClientCredentialsTokenAsync(new ClientCredentialsTokenRequest
            {
                Address = disco.TokenEndpoint,

                ClientId = "client",
                ClientSecret = "secret",
                Scope = "api"
            });

            if (tokenResponse.IsError)
            {
                Console.WriteLine(tokenResponse.Error);
                return;
            }

            Console.WriteLine(tokenResponse.Json);

            // call api
            var client2 = new HttpClient();
            client2.SetBearerToken(tokenResponse.AccessToken);

            var response = await client2.GetAsync("http://localhost:5001/weatherforecast");
            if (!response.IsSuccessStatusCode)
            {
                Console.WriteLine(response.StatusCode);
            }
            else
            {
                var content = await response.Content.ReadAsStringAsync();
                Console.WriteLine(JArray.Parse(content));
            }
        }
    }
}

先启动 IdentityServerCenter，ClientCredentialApi

再启动 ThirdPartyDemo，输出如下：
