Question

In wcf service.  how detect incoming request operating system like Android or IOS.

Answer 1

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

/// <summary>
/// Representsa run-time behavior extension for a client endpoint.
/// </summary>
public class CustomEndpointBehavior : IEndpointBehavior
{
/// <summary>
/// Implements a modification or extension of the client across an endpoint.
/// </summary>
/// <param name="endpoint">The endpoint that is to be customized.</param>
/// <param name="clientRuntime">The client runtime to be customized.</param>
public void ApplyClientBehavior(ServiceEndpoint endpoint, ClientRuntime clientRuntime)
{
clientRuntime.ClientMessageInspectors.Add(new ClientMessageInspector());
}
/// <summary>
/// Implement to pass data at runtime to bindings to support custom behavior.
/// </summary>
/// <param name="endpoint">The endpoint to modify.</param>
/// <param name="bindingParameters">The objects that binding elements require to support the behavior.</param>
public void AddBindingParameters(ServiceEndpoint endpoint, BindingParameterCollection bindingParameters)
{
// Nothing special here
}

/// <summary>
/// Implements a modification or extension of the service across an endpoint.
/// </summary>
/// <param name="endpoint">The endpoint that exposes the contract.</param>
/// <param name="endpointDispatcher">The endpoint dispatcher to be modified or extended.</param>
public void ApplyDispatchBehavior(ServiceEndpoint endpoint, EndpointDispatcher endpointDispatcher)
{
// Nothing special here
}

/// <summary>
/// Implement to confirm that the endpoint meets some intended criteria.
/// </summary>
/// <param name="endpoint">The endpoint to validate.</param>
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:

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

Answer 2

Mangesh,

I want to check and log incoming request coming from which Device/os i.e  androids or IOS.

Answer 3

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

 

 

Answer 4

I have checked no option showing for os detection. can you tell me where i will get OS details Like Android or IOS.

Answer 5

U cab check for the uaeragent of the request
