如何在Xamarin Forms App中检查post方法中的api连接？

Question

我正在开发一个 xamarin 表单应用程序，我使用我们的 api。我需要检查“HttpResponseMessage”。我可以在“get”方法中检查这一点，但在“post”方法中无法弄清楚。 我如何在 post 方法中检查此响应？

这是我的代码：

try
            {
                HttpResponseMessage response = new HttpResponseMessage(HttpStatusCode.RedirectMethod);
                response = await client.GetAsync(result);
                if (response.IsSuccessStatusCode == true)
                { 
                    //Convert Json                     
                    return JsonConvert.DeserializeObject<Model.Result>(result);

                } else if (response == null)
                {
                    // Show alert for failed calls
                    Model.Result nullResult = new Model.Result { ResultCode = 200, ResultData = "", ResultFlag = false, ResultValue = "Bağlantı Kesildi." };
                    return nullResult;
                }
            }
            catch (Exception ex)
            {
                Model.Result nullResult = new Model.Result { ResultCode = 0, ResultData = "", ResultFlag = false, ResultValue = $"Bağlantı kesildi. Sistem Mesajı: \r\n{ex.Message}" };
                Console.WriteLine(ex.Message);
                return nullResult;
                throw;
            }

发帖方法：

 try
        { // http client oluşturma
            HttpClient client = new HttpClient();
            //Client Adres
            var baseUrl= Preferences.Get("URL", "");
            string url = $"http://" + baseUrl+ "/samplePost";
            // Jsona dönüştürülecek object
             

            // Object to json
            string json = JsonConvert.SerializeObject(apiParameter);               
            
            var content = new StringContent(json, Encoding.UTF8, "application/json");
            // Post methodu 

            var postData = await client.PostAsync(url, content);

            // Read response from post 
            var result = await postData.Content.ReadAsStringAsync();


            // Json Convert

            return JsonConvert.DeserializeObject<Model.Result>(result);

        }
        catch (Exception ex)
        {
            Console.WriteLine(ex.Message);

            throw;
        }

有一个简单的例子：

var client = new HttpClient();
client.BaseAddress = new Uri("localhost:8080");

string jsonData = @"{""username"" : ""myusername"", ""password"" : ""mypassword""}"

var content = new StringContent (jsonData, Encoding.UTF8, "application/json");
HttpResponseMessage response = await client.PostAsync("/foo/login", content);

// this result string should be something like: "{"token":"rgh2ghgdsfds"}"
var result = await response.Content.ReadAsStringAsync();

注：

其中

/foo/login

需要指向您的 HTTP 资源。例如，如果您有一个带有 Login 方法的 AccountController，那么您可以使用类似

/foo/login

的内容来代替

/Account/Login

。
