For request in operation UploadPhotoStream to be a stream the operation must have a single parameter whose type is Stream

Question

I've been searching this issue but still unable to find exact solution.

Code:

namespace StackSample.Logic
{
    [ServiceHeaderBehavior]
    [MerchantHeaderBehavior]
    [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
    public class Merchant : Interfaces.IMerchant
    {
        public bool UploadPhotoStream(string productid, string photoid, Stream fileData)
        {
            Logic.Components.Product ca = new Logic.Components.Product();
            return ca.UploadPhotoStream(Common.UserValues().Merchant, productid, photoid, fileData);
        }
    }
}

namespace StackSample.Interfaces
{
    [ServiceContract]
    public interface IMerchant
    {
        [OperationContract]
        [WebInvoke(UriTemplate = "UploadPhotoStream?productid={productid}&photoid={photoid}", Method = "POST")]
        bool UploadPhotoStream(string productid, string photoid, Stream fileData);
    }
}

When I try to run http://localhost:64039/Merchant/Merchant.svc
It shows an error:

For request in operation UploadPhotoStream to be a stream the operation must have a single parameter whose type is Stream.  

I don't have any idea on what to do.

Answer 1

For future viewers, if you want to achieve this goal, wherein you will be able to put multiple parameters together with Stream, what you need to do is to avoid using SVC files to create Rest or Soap service. Instead add this on your services project, Global.asax file, the make route table, like for example:

public class Global : System.Web.HttpApplication
{
    RouteTable.Routes.Add(new ServiceRoute("MyApp/rest/Photo", new WebServiceHostFactory(), typeof(PhotoComponent)));
}  

In your web service:

[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class PhotoComponent : Interfaces.IPhotoComponent
{
    public bool UploadPhotoStream(string productid, string photoid, Stream fileData)
    {
        // some code....
    }
}

[ServiceContract]
public interface PhotoComponent
{
    [OperationContract]
    [WebInvoke(UriTemplate = "UploadPhotoStream/{productid}/{photoid}", Method = "POST")]
    bool UploadPhotoStream(string productid, string photoid, System.IO.Stream fileData);
}  

inside web.config:

<services>  
  <service behaviorConfiguration="Default" name="StackSample.Logic.PhotoComponent">
    <endpoint behaviorConfiguration="JSON" binding="webHttpBinding" bindingConfiguration="RESTSecureTransfer" contract="StackSample.Interfaces.PhotoComponent" />
  </service>
</services>   

and call it:

https://127.0.0.1/MyApp/rest/Photo/UploadPhotoStream/{productid}/{photoid}  

Hope it helps.

You need to have a single parameter in your operation that takes in an object that contains properties that you need.

See code below for example:

public interface IMerchant
{
    bool UploadPhotoStream(UploadData request);
}

public class YourService : IMerchant
{
    public bool UploadPhotoStream(UploadData request)
    {
        throw new NotImplementedException();
    }
}

[DataContract]
public class UploadData
{
    [DataMember]
    string ProductId { get; set; }

    [DataMember]
    string PhotoId { get; set; }

    [DataMember]
    System.IO.Stream FileData { get; set; }
}
