OAuth2认证和授权：ResourceOwnerPassword认证

ResourceOwnerPassword在 ClientCredentials认证上新增了用户名和密码

但通过RequestPasswordTokenAsync获取不到refresh_token，不知道为什么

            DiscoveryCache _cache = new DiscoveryCache(Authority);
            var disco1 = _cache.GetAsync().Result;
            if (disco1.IsError) throw new Exception(disco1.Error);
            //或者
            var disco = tokenCliet.GetDiscoveryDocumentAsync(Authority).Result;
            if (disco.IsError) throw new Exception(disco.Error);


            var response = tokenCliet.RequestPasswordTokenAsync(new PasswordTokenRequest

            var token = response.AccessToken;

            //把token，Decode
            if (response.AccessToken.Contains("."))
            {
                //Console.WriteLine("\nAccess Token (decoded):");

                Console.WriteLine("\nAccess Token (decoded):");
                Console.ResetColor();

                var parts = response.AccessToken.Split('.');
                var header = parts[0];
                var claims = parts[1];

                Console.WriteLine(JObject.Parse(Encoding.UTF8.GetString(Base64Url.Decode(header))));
                Console.WriteLine(JObject.Parse(Encoding.UTF8.GetString(Base64Url.Decode(claims))));
            }
            //设置请求的Token
            tokenCliet.SetBearerToken(token);
            //请求并返回字符串
            var apiResource1 = tokenCliet.GetStringAsync("identity").Result;
            var userinfo = tokenCliet.GetStringAsync("identity/userinfo").Result;

            var j = JObject.Parse(userinfo);
            //或者
            var getVal = tokenCliet.GetAsync("api/values").Result;
            if (getVal.IsSuccessStatusCode)
            {
                Console.WriteLine(getVal.Content.ReadAsStringAsync().Result);
            }
            Console.ReadLine();
        }
    }
}

但自己写一个请求方式，是可以获取到的

HttpClientHepler帮助类，参考网上

  public class HttpClientHepler
    {
        string _url;
        public string Url
        {
            get

            set
            {
                _url = value;
            }
        }

        public HttpClientHepler(string url)
        {
            Url = url;
        }

        public async Task GetAsync(string queryString, Action<HttpRequestHeaders> addHeader,
            Action<string> okAction = null,
            Action<HttpResponseMessage> faultAction = null, Action<Exception> exAction = null)
        {
            using (HttpClient client = new HttpClient())
            {
                addHeader(client.DefaultRequestHeaders);
                using (HttpResponseMessage response = await client.GetAsync(Url + "?" + queryString))
                {
                    try
                    {
                        if (response.IsSuccessStatusCode)
                        {
                            okAction(await response.Content.ReadAsStringAsync());
                        }

                        {
                            faultAction?.Invoke(response);
                        }
                    }
                    catch (Exception ex)
                    {
                        exAction?.Invoke(ex);
                    }
                }
            }
        }

                {

                            }
                            else
                            {
                                faultAction?.Invoke(response);

                        }
                    }
                }
            }
        }


    }

黄色标记部分是新增代码，运行获取成功

   static void Main(string[] args)
        {
            string Authority = "http://localhost:5003";
            string ApiResurce = "http://localhost:5002/";
            var tokenCliet = new HttpClient()
            {
                BaseAddress = new Uri(ApiResurce)
            };



            /*

 用RefreshToken刷新也成功
