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

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 metadatavar client = new HttpClient();var disco = client.GetDiscoveryDocumentAsync("http://localhost:5000").Result;if (disco.IsError){Console.WriteLine(disco.Error);return;}// request tokenvar 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 apivar 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：
