一個api回傳：發送webservice請求時不允許方法

我有一個正在運行的 web 服務，我只有一個 api 呼叫，它運行完美。
所以現在我想添加另一個 api 但我無法讓這個作業，當我在瀏覽器中嘗試時它一直回傳這個錯誤

請求包含物體主體但不包含 Content-Type 標頭。此資源不支持推斷的媒體型別“應用程式/八位位元組流”

如果我在我的 testclient c# 專案中嘗試它，它會回傳 Method not allowed

我所做的與已經在作業的 api 完全相同，那么這個令人討厭的錯誤的原因是什么？

來自作業api的代碼

public class SCSController : ApiController
{
    // GET: SCS
    public HttpResponseMessage AddDriverPayments(DriverPayment driverPayments)
        {
            HttpResponseMessage result = null;

            try
            {
                DriverPaymentResponse response = new DriverPaymentResponse() { PaymentID = driverPayments.newID, SCS_ID = driverPayments.sCS_ID };
                result = Request.CreateResponse(response);
            }
            catch (Exception ex)
            {
                var resp = new HttpResponseMessage(HttpStatusCode.InternalServerError)
                {
                    Content = new StringContent("error"),
                    ReasonPhrase = ex.Message
                };
                throw new HttpResponseException(resp);
            }

            return result;
        }

來自不作業的api的代碼

    public class VLAController : ApiController
    {

        // GET: VLA
        public HttpResponseMessage GetAppLogin(AppLoginRequest appLoginRequest)
        {
            HttpResponseMessage result = null;

            try
            {
                //VLADataBase db = new VLADataBase();
                //AppLoginResponse response = db.GetAppLogin(appLoginRequest);
                AppLoginResponse response = new AppLoginResponse() { Authorized = true, TruckID = 123 };
                result = Request.CreateResponse(response);
            }
            catch (Exception ex)
            {
                var resp = new HttpResponseMessage(HttpStatusCode.InternalServerError)
                {
                    Content = new StringContent("error"),
                    ReasonPhrase = "fout: "   ex.Message
                };
                throw new HttpResponseException(resp);
            }

            return result;
        }

我如何在我的測驗客戶端中呼叫它

這就是我呼叫作業 api 的方式

  string JsonData = JsonConvert.SerializeObject(payments);
            System.Net.Http.StringContent restContent = new StringContent(JsonData, Encoding.UTF8, "application/json");
            HttpClient client = new HttpClient();
            try
            {
                var response = await client.PostAsync(comboBoxEditWebService.Text, restContent);

                if (response.IsSuccessStatusCode)
                {
                    var stream = await response.Content.ReadAsStringAsync();
                    DriverPaymentResponse Result = JsonConvert.DeserializeObject<DriverPaymentResponse>(stream);

                    textBoxResult.Text = Result.SCS_ID   " "   Result.PaymentID;
                }
                else
                {
                    textBoxResult.Text = response.StatusCode   " "   response.ReasonPhrase;
                }
            }
            catch (Exception ex)
            {
                textBoxResult.Text = ex.Message;
            }

這就是我如何稱呼不作業的 api

   string JsonData = JsonConvert.SerializeObject(appLoginRequest);
            System.Net.Http.StringContent restContent = new StringContent(JsonData, Encoding.UTF8, "application/json");
            HttpClient client = new HttpClient();
            try
            {
                var response = await client.PostAsync(comboBoxEdit1.Text, restContent);

                if (response.IsSuccessStatusCode)
                {
                    var stream = await response.Content.ReadAsStringAsync();
                    AppLoginResponse Result = JsonConvert.DeserializeObject<AppLoginResponse>(stream);

                    textBox1.Text = Result.Authorized.ToString()   " "   Result.TruckID.ToString(); //Result.SCS_ID   " "   Result.PaymentID;
                }
                else
                {
                    textBox1.Text = response.StatusCode   " "   response.ReasonPhrase;
                }
            }
            catch (Exception ex)
            {
                textBox1.Text = ex.Message;
            }

我必須注意，兩個 api 都在不同的單元中，在不同的控制器中，也許這可能是一個問題？

So how can I get this solved so I can use both api's ?

裝飾端點[HttpPost]就成功了（請參閱評論中的對話）。
