前言

前面写了两篇IdentityServer4文章，一篇是资源服务器创建（.NET Core集成Identityserver4），一篇是服务集成IdentityServer4认证（Asp.Net Core服务集成Identityserver4认证），测试都是postman工具进行测试的，今天编程控制台来演示请求的相关流程。代码框架环境Asp.net Core 3.1

一、使用步骤

1.创建一个控制台程序，进行消费，名称为OrderCounsumerk

2.引入IdentityModel 库 4.4.0

3.代码编写

1. 客户端模式

代码如下（示例）：

       var client = new HttpClient();

            var response = client.RequestClientCredentialsTokenAsync(new ClientCredentialsTokenRequest
            {
                Address = "http://localhost:5000/connect/token",
                ClientId = "client",
                ClientSecret = "secret",
                Scope = "api"
            }).Result;
            Console.WriteLine("=============================Token==============================");

            Console.WriteLine(response.AccessToken ?? response.Error);

            Console.WriteLine("=============================Token==============================");
            // 调用API
            client.SetBearerToken(response.AccessToken);

            var responses = client.GetAsync("http://localhost:5001/weatherforecast/get").Result;
            if (response.IsError)
            {
                Console.WriteLine(response.HttpStatusCode);
            }
            else
            {
                Console.WriteLine("=============================服务返回值==============================");
                var content = responses.Content.ReadAsStringAsync().Result;
               
                Console.WriteLine(content);
            }
            Console.WriteLine("Hello World!");
            Console.ReadKey();

2. 密码模式

代码如下（示例）：

        var client = new HttpClient();

            var response = client.RequestPasswordTokenAsync(new PasswordTokenRequest
            {
                Address = "http://localhost:5000/connect/token",
                ClientId = "apiClientPassword",
                ClientSecret = "apiSecret",
                Scope = "secretapi",
                UserName="123",
                Password="123"
                
            }).Result;
            Console.WriteLine("=============================Token==============================");

            Console.WriteLine(response.AccessToken ?? response.Error);

            Console.WriteLine("=============================Token==============================");
            // 调用API
            client.SetBearerToken(response.AccessToken);

            var responses = client.GetAsync("http://localhost:5001/weatherforecast/get").Result;
            if (response.IsError)
            {
                Console.WriteLine(response.HttpStatusCode);
            }
            else
            {
                Console.WriteLine("=============================服务返回值==============================");
                var content = responses.Content.ReadAsStringAsync().Result;

                Console.WriteLine(content);
            }
            Console.WriteLine("Hello World!");
            Console.ReadKey();

3. 刷新refresh_token

代码如下（示例）：

        var client = new HttpClient();

            var response = client.RequestPasswordTokenAsync(new PasswordTokenRequest
            {
                Address = "http://localhost:5000/connect/token",
                ClientId = "apiClientPassword",
                ClientSecret = "apiSecret",
                Scope = "secretapi",
                UserName="123",
                Password="123"
                
            }).Result;
            Console.WriteLine("=============================Token==============================");

            Console.WriteLine(response.AccessToken ?? response.Error);

            Console.WriteLine("=============================Token==============================");
            // 调用API
            client.SetBearerToken(response.AccessToken);

            var responses = client.GetAsync("http://localhost:5001/weatherforecast/get").Result;
            if (response.IsError)
            {
                Console.WriteLine(response.HttpStatusCode);
            }
            else
            {
                Console.WriteLine("=============================服务返回值==============================");
                var content = responses.Content.ReadAsStringAsync().Result;

                Console.WriteLine(content);
            }
            Console.WriteLine("Hello World!");
            Console.ReadKey();
