wcf通过代码添加绑定和内容类型映射

Binding and webContentTypeMapperType

RawContentTypeMapper

 public class RawContentTypeMapper : WebContentTypeMapper
        {
            public override WebContentFormat GetMessageFormatForContentType(string contentType)
            {
                switch (contentType.ToLowerInvariant())
                {
                    case "text/plain":
                    case "application/json":
                        return WebContentFormat.Raw;
                    case "application/xml":
                        return WebContentFormat.Xml;
                    default:
                        return WebContentFormat.Default;
                }
            }
        }

添加绑定

　　　 var serviceEndpoint = new ServiceEndpoint(wcfcontract, binding, new EndpointAddress(upgrade_service_address));   

 　　　WebMessageEncodingBindingElement webMEBE = new WebMessageEncodingBindingElement();
      webMEBE.ContentTypeMapper = new FileUploadServices.StreamBinding.StreamBindingMapper();
      HttpTransportBindingElement httpTBE = new HttpTransportBindingElement();
      httpTBE.TransferMode = TransferMode.StreamedRequest;
      httpTBE.KeepAliveEnabled = true;
      httpTBE.MaxReceivedMessageSize = 2000000000;
      httpTBE.MaxBufferSize = 65536;
      httpTBE.ManualAddressing = true;
      CustomBinding rawBinding = new CustomBinding(webMEBE, httpTBE);
      rawBinding.OpenTimeout = TimeSpan.FromMinutes(5);
      rawBinding.CloseTimeout = TimeSpan.FromMinutes(5);
      rawBinding.SendTimeout = TimeSpan.FromMinutes(5);
      rawBinding.ReceiveTimeout = TimeSpan.FromMinutes(5);
      serviceEndpoint.Binding = rawBinding;

host.AddServiceEndpoint(serviceEndpoint);
