WCF REST POST JSON - 远程服务器返回错误：（400）错误的请求

我试图将数据发布到WCF REST服务，我不断收到错误远程服务器返回错误：（400）错误的请求。我的代码如下WCF REST POST JSON - 远程服务器返回错误：（400）错误的请求

的ServiceContract：

[ServiceContract(Namespace="AppointmentService")] 
public interface IAppointmentService 
{ 
    [OperationContract] 
    [WebInvoke(UriTemplate = "/edit", Method = "POST", RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.Bare)] 
    string UpdateAppointment(AppointmentContract appointmentEntity); 
}

服务：

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] 
[ServiceBehavior(InstanceContextMode=InstanceContextMode.PerCall)] 
public class FrontOfficeRest:IAppointmentService 
{ 
    #region Appointments 
    public string UpdateAppointment(AppointmentContract appointmentEntity) 
    { 
     AppointmentList appList = new AppointmentList(); 
     appList = appointmentDAO.GetAllAppointmentsByDocotorAndDate(Convert.ToInt32(appointmentEntity.doctorId), Convert.ToDateTime(appointmentEntity.appointmentDate)); 
     if (appList.Count > 0) 
     { 
      var chApp = appList 
       .Where(a => TimeSpan.Parse(a.startTime) == TimeSpan.Parse(appointmentEntity.startTime) 
        || (TimeSpan.Parse(a.startTime) < TimeSpan.Parse(appointmentEntity.startTime) 
        && TimeSpan.Parse(a.endTime) > TimeSpan.Parse(appointmentEntity.startTime))) 
       .Select(a => a); 

      if (chApp.Count() > 0) 
       throw new WebFaultException<string>(string.Format("The Doctor is not available between {0} and {1}", appointmentEntity.startTime, appointmentEntity.endTime), HttpStatusCode.Conflict); 
     } 
     bool updResult = appointmentDAO.UpdateAppointment(appointmentEntity); 
     OutgoingWebResponseContext ctx = WebOperationContext.Current.OutgoingResponse; 
     string retRes = string.Empty; 
     if (!updResult) 
     { 
      ctx.StatusCode = HttpStatusCode.NotModified; 
      retRes = "FAIL"; 
     } 
     else 
     { 
      retRes = "SUCESS"; 
      ctx.StatusCode = HttpStatusCode.OK; 
     } 
     return retRes; 
    } 

    #endregion 
}

ClientCode

  string address = "http://localhost:8080/FrontOfficeRest/AppointmentService/edit"; 
      Uri uri = new Uri(address); 
      RestClientUtility utl = new RestClientUtility(); 

      utl.ExecuteRequest<string>(uri, "POST", appointment); 

    public void ExecuteRequest<T>(Uri uri, string method, object data) 
    { 
     HttpWebRequest request = (HttpWebRequest)WebRequest.Create(uri); 
     request.Method = method; 
     request.ContentType = "application/json; charset=utf-8"; 
     DataContractJsonSerializer serializer = new DataContractJsonSerializer(data.GetType()); 
     JavaScriptSerializer oSerializer = new JavaScriptSerializer(); 
     string dataAsString = oSerializer.Serialize(data); 
     byte[] byteData = UTF8Encoding.UTF8.GetBytes(dataAsString); 
     request.ContentLength = byteData.Length; 

     using (Stream requestStream = request.GetRequestStream()) 
     { 
      //requestStream.Write(byteData, 0, byteData.Length); 
      serializer.WriteObject(requestStream, data); 
     } 
     try 
     { 
      using (HttpWebResponse response = request.GetResponse() as HttpWebResponse) 
      { 
       DataContractJsonSerializer deserializer = new DataContractJsonSerializer(typeof(T)); 
       Stream responseStream = response.GetResponseStream(); 
       //result = (T)deserializer.ReadObject(responseStream); 
      } 
     } 
     catch (WebException e) 
     { 
      using (WebResponse response = e.Response) 
      { 
       HttpWebResponse httpResponse = (HttpWebResponse)response; 
       Console.WriteLine("Error code: {0}", httpResponse.StatusCode); 
       using (Stream datat = response.GetResponseStream()) 
       { 
        string text = new StreamReader(datat).ReadToEnd(); 
        Console.WriteLine(text); 
       } 
      } 
     } 

    }

的ServiceHost：

 string httpUri = "http://localhost:8080/FrontOfficeRest/"; 
     WebHttpBinding binding = new WebHttpBinding(); 
     binding.MaxBufferSize = 4194304; 
     binding.MaxReceivedMessageSize = 4194304; 
     WebServiceHost host = new WebServiceHost(typeof(FrontOfficeRest)); 
     host.AddServiceEndpoint(typeof(IAppointmentService), binding, httpUri + "AppointmentService"); 
     Console.WriteLine("Appointment Service");

我得到的错误，而使用处理请求（HttpWebResponse响应= request.GetResponse（）作为HttpWebResponse）

我使用Windows 7 IIS 7.0没有配置文件。任何人都可以帮忙吗？

这是堆栈跟踪

为了解答这个问题，你可以发送你发送给服务器的HTTP请求和它返回的响应 - 这是重要的信息。 –

尝试启用的服务跟踪。跟踪将有一个例外，这将解释为什么服务器认为请求不好。 – carlosfigueira

@SIDDHARTH如果看到堆栈跟踪，您将看到异常消息

LINQ到实体无法识别方法“的Int32 ToInt32（System.String） '方法，并且此方法不能转换为商店表达式。

在UNSER UpdateAppointment你会发现下面的代码 Convert.ToInt32（appointmentEntity.doctorId）

将字符串值转换的Int32如下图所示
INT doctorId =转换初始化APPLIST之前的方法服务类。 ToInt32（appointmentEntity.doctorId）

这是LINQ到实体
