HttpListenerContext.Response 属性
重要
一些信息与预发行产品相关，相应产品在发行之前可能会进行重大修改。 对于此处提供的信息，Microsoft 不作任何明示或暗示的担保。
获取 HttpListenerResponse 对象，该对象将被发送到客户端以响应客户端的请求。
public:
property System::Net::HttpListenerResponse ^ Response { System::Net::HttpListenerResponse ^ get(); };C#
public System.Net.HttpListenerResponse Response { get; }member this.Response : System.Net.HttpListenerResponsePublic ReadOnly Property Response As HttpListenerResponse用于将响应发送回客户端的 HttpListenerResponse 对象。
下面的代码示例演示如何获取对客户端请求的响应并添加响应正文。
C#
// 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();
}

应用程序通过在此属性返回的 对象中 HttpListenerResponse 设置属性来配置响应。 配置响应后，可通过关闭响应或关闭此 HttpListenerContext 对象将其发送到客户端。
