In wcf service. how detect incoming request operating syste

HTTP headers, request messages can be intercepted before they are sent to the server. This can be done by implementing the IClientMessageInspector.BeforeSendRequestmethod:

///
/// Representsa run-time behavior extension for a client endpoint.
///
public class CustomEndpointBehavior : IEndpointBehavior
{
///
/// Implements a modification or extension of the client across an endpoint.
///
/// The endpoint that is to be customized.
/// The client runtime to be customized.
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.ClientMessageInspectors.Add(new ClientMessageInspector());
}
///
/// Implement to pass data at runtime to bindings to support custom behavior.
///
/// The endpoint to modify.
/// The objects that binding elements require to support the behavior.
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
// Nothing special here
}
///
/// Implements a modification or extension of the service across an endpoint.
///
/// The endpoint that exposes the contract.
/// The endpoint dispatcher to be modified or extended.
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
// Nothing special here
}
///
/// Implement to confirm that the endpoint meets some intended criteria.
///
/// The endpoint to validate.
public void Validate(ServiceEndpoint endpoint)
{
// Nothing special here
}

This interception is a behavior or an extension of WCF endpoints, so one more method needs to be implemented to apply that behavior to the endpoint, the IEndpointBehavior.ApplyClientBehavior method:

///
/// Represents a run-time behavior extension for a client endpoint.
///
public class CustomEndpointBehavior : IEndpointBehavior
{
///
/// Implements a modification or extension of the client across an endpoint.
///
/// The endpoint that is to be customized.
/// The client runtime to be customized.
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.ClientMessageInspectors.Add(new ClientMessageInspector());
}
///
/// Implement to pass data at runtime to bindings to support custom behavior.
///
/// The endpoint to modify.
/// The objects that binding elements require to support the behavior.
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
// Nothing special here
}
///
/// Implements a modification or extension of the service across an endpoint.
///
/// The endpoint that exposes the contract.
/// The endpoint dispatcher to be modified or extended.
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
// Nothing special here
}
///
/// Implement to confirm that the endpoint meets some intended criteria.
///
/// The endpoint to validate.
public void Validate(ServiceEndpoint endpoint)
{
// Nothing special here
}
}

The last step is to add the new behavior to the WCF endpoint:

Endpoint.EndpointBehaviors.Add(new CustomEndpointBehavior());

Mangesh,

I want to check and log incoming request coming from which Device/os i.e androids or IOS.
Mangesh G8y ago
Subhash
i doubt if we can get them if u have checked then its better u are sending the value from the client (i.e. androids or IOS) itself
Subhashkumar Yadav8y ago
I have checked no option showing for os detection. can you tell me where i will get OS details Like Android or IOS.
Mangesh G8y ago
U cab check for the uaeragent of the request
