Obtiene el objeto HttpListenerResponse que se enviará al cliente en respuesta a la solicitud del cliente.

public:
 property System::Net::HttpListenerResponse ^ Response { System::Net::HttpListenerResponse ^ get(); };
public System.Net.HttpListenerResponse Response { get; }
member this.Response : System.Net.HttpListenerResponse
Public ReadOnly Property Response As HttpListenerResponse

Valor de propiedad

HttpListenerResponse

Un objeto HttpListenerResponse que permite devolver una respuesta al cliente.

Ejemplos

En el ejemplo de código siguiente se muestra cómo obtener la respuesta a la solicitud de un cliente y agregar el cuerpo de la respuesta.

// This example requires the System and System.Net namespaces.
public static string ClientInformation(HttpListenerContext context)
{
    System.Security.Principal.IPrincipal user = context.User;
    System.Security.Principal.IIdentity id = user.Identity;
    if (id == null)
    {
        return "Client authentication is not enabled for this Web server.";
    }

    string display;
    if (id.IsAuthenticated)
    {
        display = String.Format("{0} was authenticated using {1}", id.Name,
            id.AuthenticationType);
    }
    else
    {
       display = String.Format("{0} was not authenticated", id.Name);
    }
    return display;
}

public static void SimpleListenerWithAuthentication(string[] prefixes)
{
    if (!HttpListener.IsSupported)
    {
        Console.WriteLine ("Windows XP SP2 or Server 2003 is required to use the HttpListener class.");
        return;
    }

    // URI prefixes are required,
    // for example "http://contoso.com:8080/index/".
    if (prefixes == null || prefixes.Length == 0)
      throw new ArgumentException("prefixes");

    // Set up a listener.
    HttpListener listener = new HttpListener();
    foreach (string s in prefixes)
    {
        listener.Prefixes.Add(s);
    }
    listener.Start();
    // Specify Negotiate as the authentication scheme.
    listener.AuthenticationSchemes = AuthenticationSchemes.Negotiate;
    Console.WriteLine("Listening...");
    // GetContext blocks while waiting for a request.
    HttpListenerContext context = listener.GetContext();
    HttpListenerRequest request = context.Request;
    // Obtain a response object.
    HttpListenerResponse response = context.Response;
    // Construct a response.
    string clientInformation = ClientInformation(context);
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes("<HTML><BODY> " + clientInformation + "</BODY></HTML>");
    // Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length;
    System.IO.Stream output = response.OutputStream;
    output.Write(buffer,0,buffer.Length);
    output.Close();
    listener.Stop();
}

' This example requires the System and System.Net namespaces.
Public Shared Function ClientInformation(ByVal context As HttpListenerContext) As String
    Dim user As System.Security.Principal.IPrincipal = context.User
    Dim id As System.Security.Principal.IIdentity = user.Identity

    If id Is Nothing Then
        Return "Client authentication is not enabled for this Web server."
    End If

    Dim display As String

    If id.IsAuthenticated Then
        display = String.Format("{0} was authenticated using {1}", id.Name, id.AuthenticationType)
    Else
        display = String.Format("{0} was not authenticated", id.Name)
    End If

    Return display
End Function

Public Shared Sub SimpleListenerWithAuthentication(ByVal prefixes As String())
    If Not HttpListener.IsSupported Then
        Console.WriteLine("Windows XP SP2 or Server 2003 is required to use the HttpListener class.")
        Return
    End If

    ' URI prefixes are required,
    ' for example "http://contoso.com:8080/index/"
    If prefixes Is Nothing OrElse prefixes.Length = 0 Then Throw New ArgumentException("prefixes")
    Dim listener As HttpListener = New HttpListener()

    For Each s As String In prefixes
        listener.Prefixes.Add(s)
    Next

    listener.Start()
    ' Specify Negotiate as the authentication scheme.
    listener.AuthenticationSchemes = AuthenticationSchemes.Negotiate
    Console.WriteLine("Listening...")
    ' GetContext blocks while waiting for a request.
    Dim context As HttpListenerContext = listener.GetContext()
    Dim request As HttpListenerRequest = context.Request
    ' Obtain a response object.
    Dim response As HttpListenerResponse = context.Response
    Dim clientInformationString As String = ClientInformation(context)
    Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes("<HTML><BODY> " & clientInformationString & "</BODY></HTML>")
    ' Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length
    Dim output As System.IO.Stream = response.OutputStream
    output.Write(buffer, 0, buffer.Length)
    output.Close()
    listener.Stop()
End Sub

Comentarios

La aplicación configura la respuesta estableciendo propiedades en el HttpListenerResponse objeto devuelto por esta propiedad. Después de configurar la respuesta, se envía al cliente cerrando la respuesta o cerrando este HttpListenerContext objeto.
