WebInvoke POST "Method not allowed" in Wcf

Question

my Rest wcf service as below...

[ServiceContract]
public interface IWinPhoneService
{

[OperationContract]
[WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "getkpimeasuredata", Method = "POST", BodyStyle = WebMessageBodyStyle.Wrapped)]
List<MeasureData> GetKpiMeasureData(DomainData data);


[OperationContract]
[WebGet(UriTemplate = "getdata/{value}", ResponseFormat = WebMessageFormat.Json)]
string GetData(string value);


// TODO: Add your service operations here
}

[DataContract]
public class DomainData
{
    [DataMember]
    public int? KPIId
    {
        get;
        set ;
    }

[DataMember]
public int? ScorecardId
{
    get;
    set;
}

[DataMember]
public short? CumulativeMonth
{
    get;
    set;
}

[DataMember]
public int? EngineeringOrgId
{
    get;
    set;
}

[DataMember]
public int? BusinessOrgId
{
    get;
    set;
}
[DataMember]
public int? DataValuetypeId
{
    get;
    set;
}

}

and when I consume this service using Restsharp as below

string URL = "http://<servername>:8085/WinPhoneService.svc";

            RestClient client = new RestClient(URL);

            RestRequest request = new RestRequest("getkpimeasuredata",Method.POST);
            DomainData data = new DomainData();
            data.KPIId = 1006;
            data.ScorecardId = 3;
            data.EngineeringOrgId = 11;
            data.DataValuetypeId = 1;
            data.CumulativeMonth = 463;
            data.BusinessOrgId = 1;

            string json = Newtonsoft.Json.JsonConvert.SerializeObject(data);

            json = "{\"data\" : " + json + "}";

            request.AddParameter("application/json; charset=utf-8", json, ParameterType.RequestBody);
            request.RequestFormat = DataFormat.Json;
 client.ExecuteAsync(request, response =>
            {
                if (response.StatusCode == HttpStatusCode.OK)
                {



                }
                else
                {
                    //NOK
                }
            });

Even tried a webget method also as below..

 RestClient client1 = new RestClient(URL);
            RestRequest request1 = new RestRequest(string.Format("getdata/{0}", 1), Method.GET);
            request1.RequestFormat = DataFormat.Json;

            var x = client1.ExecuteAsync(request1, response =>
                {
                    if (response.StatusCode == HttpStatusCode.OK)
                    {

                    }
                });

Im able to the response.StatusCode as NotFound and even when I checked fiddler the service is not hitting at all and when I verified the service url in composer im getting the error as "HTTP/1.1 405 Method Not Allowed"

and even when I tried with Webclient as below

string URL = "http://<servername>:8085/WinPhoneService.svc";
            WebClient wclient = new WebClient();
            wclient.UseDefaultCredentials = true;
            wclient.Headers["Content-Type"] = "application/json";


            DomainData kpidata = new DomainData();
            data.KPIId = 1006;
            data.ScorecardId = 3;
            data.EngineeringOrgId = 11;
            data.DataValuetypeId = 1;
            data.CumulativeMonth = 463;
            data.BusinessOrgId = 1;

            string json = SerializeJson(kpidata);
            String str = wclient.UploadString(new Uri(URL ),"getkpimeasuredata",json);

Even here im getting "HTTP/1.1 405 Method Not Allowed" but atleast in this case its hitting the service as shown in fiddler

PFB the webconfig for the same...

Please help me regarding the same..

the function which I use in win8 mobile app is

public async void  LoadKpiData()
        {
                       string URL = "http://rr1biscdevsql01:8085/WinPhoneService.svc/getkpimeasuredata;
            WebClient wclient = new WebClient();
            wclient.UseDefaultCredentials = true;
            wclient.Headers["Content-Type"] = "application/json";

            DomainData kpidata = new DomainData();
            kpidata.KPIId = 1006;
            kpidata.ScorecardId = 3;
            kpidata.EngineeringOrgId = 11;
            kpidata.DataValuetypeId = 1;
            kpidata.CumulativeMonth = 463;
            kpidata.BusinessOrgId = 1;

            string json = SerializeJson(kpidata);
            wclient.UploadStringAsync(new Uri(URL), json);

            wclient.UploadStringCompleted += (s, e) =>
                {

                };

        }

and when I check in response for Restclient call got error as below

Rajesh when I added [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)] in service and

<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>

in webconfig im getting error as The service cannot be activated because it does not support ASP.NET compatibility. ASP.NET compatibility is enabled for this application. Turn off ASP.NET compatibility mode in the web.config or add the AspNetCompatibilityRequirements attribute to the service type with RequirementsMode setting as 'Allowed' or 'Required'.

Actually its working fine when I run service in localhost but its throwing the error when I host the service..Please help ....

Answer 1

[WebInvoke(... , Method = "POST" ... )]List<MeasureData> GetKpiMeasureData(DomainData data);

Above code you used POST method , but you must use GET method Because POST method only is used if you will add data.

Http verbs are POST , GET , Delete and PUT(Update) . You must learn firstly.

I used Get method and RestSharp.dll for my project if You want to use my project for POST method , below code you can use

Client side

 var client1 = new RestClient("http://localhost:61111/Service1.svc");
            var request1 = new RestRequest("/AddPerson", Method.POST);
            Person person1 = new Person();
            person1.PersonID = 2;
            person1.Name = "Robert";
            person1.SurName = "Dan";
            JsonSerializer serial = new JsonSerializer();

            string temp = serial.Serialize(person1);
            Console.WriteLine(temp);
            Person tempPerson1 = new JavaScriptSerializer().Deserialize<Person>(temp);
            Console.WriteLine(tempPerson1.PersonID + " " + tempPerson1.Name + " " + tempPerson1.SurName);

Server side

public class Service1 : IService1
{       
    private Person person = new Person() { PersonID = 1, Name = "John", SurName = "Albert" };
    public Person GetPerson()
    {
        return person;
    }
    public Person AddPerson(Person person)
    {
        return person;
    }
}


[ServiceContract]
public interface IService1
{

    [OperationContract]
    [WebInvoke(Method="GET", ResponseFormat = WebMessageFormat.Json, UriTemplate = "/GetPerson")]
    Person GetPerson();
    [OperationContract]
    [WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json, UriTemplate = "/AddPerson")]
    Person AddPerson(Person person);
}

Answer 2

Look at this code

My server code as below

[ServiceContract]
    public interface IWinPhoneService
    {
        [OperationContract]
        [WebInvoke(RequestFormat = WebMessageFormat.Json, ResponseFormat = WebMessageFormat.Json, UriTemplate = "getkpimeasuredata")]
        List<String> GetKpiMeasureData(DomainData data);
    }

[DataContract]
    public class DomainData
{
    [DataMember]
    public int? KPIId { get; set; }

    [DataMember]
    public int? ScorecardId { get; set; }

    [DataMember]
    public short? CumulativeMonth { get; set; }

    [DataMember]
    public int? EngineeringOrgId { get; set; }

    [DataMember]
    public int? BusinessOrgId { get; set; }

    [DataMember]
    public int? DataValuetypeId { get; set; }
}

Now my implementation of the interface as below

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Required)]
    [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single)]
    public class WinPhoneService : IWinPhoneService
    {
        public List<string> GetKpiMeasureData(DomainData data)
        {
            if (data != null)
            {
                return new List<string>()  {"Sample 1","Sample 2"};
            }
            return new List<string>() {"No data recieved"};
        }
    }

My server side web.config for endpoint element configuration

<system.serviceModel>
<services>
    <service name="WinPhoneService.WinPhoneService">
            <endpoint address="" binding="webHttpBinding" behaviorConfiguration="web" bindingConfiguration="defaultRestJsonp" contract="WinPhoneService.IWinPhoneService">
            </endpoint>
          </service>
    </services>
    <behaviors>
    <endpointBehaviors>
            <behavior name="web">
              <webHttp />
              <dataContractSerializer maxItemsInObjectGraph="2147483647"/>
            </behavior>        
    </endpointBehaviors> 
    </behaviors>
    <bindings>   
    <webHttpBinding>
            <binding name="defaultRestJsonp" crossDomainScriptAccessEnabled="true">
              <readerQuotas maxStringContentLength="2147483647" maxArrayLength="2147483647" maxBytesPerRead="2147483647" maxDepth="64" maxNameTableCharCount="2147483647" />
              <security mode="None" />
            </binding>
  </webHttpBinding>
  </bindings>
<serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />     
 </system.serviceModel>  

Now with all the above set find my client code below using RestSharpClient:

private static string ToStringUsingDataContractJsonSer<T>(T requestBody)
        {
            var serializer = new DataContractJsonSerializer(typeof(T));
            var ms = new MemoryStream();
            serializer.WriteObject(ms, requestBody);
            ms.Position = 0;
            var reader = new StreamReader(ms);
            return reader.ReadToEnd();
        }

private string UseRestSharpApproach(string serviceBaseUrl, string resourceUrl, Method method, object requestBody)
        {
            var client = new RestClient();
            client.BaseUrl = serviceBaseUrl;
            var request = new RestRequest(method) { DateFormat = DataFormat.Xml.ToString(), Resource = resourceUrl };
            request.AddParameter("application/json", requestBody, ParameterType.RequestBody);            
            var response = client.Execute(request);

            string responseString;
            if (response.StatusCode == HttpStatusCode.OK)
            {
                responseString = HttpUtility.HtmlDecode(response.Content);
            }
            else
            {
                responseString = response.StatusDescription + " --------------------" + HttpUtility.HtmlDecode(response.Content);
            }
            return responseString;
        }

public void CallRESTService()
{
       UseRestSharpApproach(serviceBaseUrl, resourceUrl, Method.POST, ToStringUsingDataContractJsonSer<DomainData>(objDomainData));
}

Make sure that the DomainData object when using on the client side is in the same namespace as on server so that the serialization and de-serialization happens without problems.

Now my raw request from Fiddler looks as below:

POST http://servername/Sample/WinPhoneService.svc/GetKpiMeasureData HTTP/1.1
Accept: application/json, application/xml, text/json, text/x-json, text/javascript, text/xml

{"BusinessOrgId":1,"CumulativeMonth":463,"DataValuetypeId":1,"EngineeringOrgId":11,"KPIId":1006,"ScorecardId":3}

And the response looks as below:
