AuthenticationSchemeSelector 委托
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。
为 HttpListener 实例选择身份验证方案。
public delegate System::Net::AuthenticationSchemes AuthenticationSchemeSelector(HttpListenerRequest ^ httpRequest);C#
public delegate System.Net.AuthenticationSchemes AuthenticationSchemeSelector(HttpListenerRequest httpRequest);type AuthenticationSchemeSelector = delegate of HttpListenerRequest -> AuthenticationSchemesPublic Delegate Function AuthenticationSchemeSelector(httpRequest As HttpListenerRequest) As AuthenticationSchemes - httpRequest
- HttpListenerRequest
要为其选择身份验证方案的 HttpListenerRequest 实例。
AuthenticationSchemes 值之一，指示要用于指定的客户端请求的身份验证方法。
以下示例使用此类型的实例来设置 AuthenticationSchemeSelectorDelegate 属性。
C#
// Set up a listener.
HttpListener listener = new HttpListener();
HttpListenerPrefixCollection prefixes = listener.Prefixes;
prefixes.Add(@"http://localhost:8080/");
prefixes.Add(@"http://contoso.com:8080/");
// Specify the authentication delegate.
listener.AuthenticationSchemeSelectorDelegate =
new AuthenticationSchemeSelector (AuthenticationSchemeForClient);
// Start listening for requests and process them
// synchronously.
listener.Start();
' Set up a listener.
Dim listener As New HttpListener()
Dim prefixes As HttpListenerPrefixCollection = listener.Prefixes
prefixes.Add("http://localhost:8080/")
prefixes.Add("http://contoso.com:8080/")
' Specify the authentication delegate.
listener.AuthenticationSchemeSelectorDelegate = New AuthenticationSchemeSelector(AddressOf AuthenticationSchemeForClient)
' Start listening for requests and process them
' synchronously.
listener.Start()
以下示例演示上一示例中委托 AuthenticationSchemeSelector 调用的 方法的实现。
C#
static AuthenticationSchemes AuthenticationSchemeForClient(HttpListenerRequest request)
{
Console.WriteLine("Client authentication protocol selection in progress...");
// Do not authenticate local machine requests.
if (request.RemoteEndPoint.Address.Equals (IPAddress.Loopback))
{
return AuthenticationSchemes.None;
}
else
{
return AuthenticationSchemes.IntegratedWindowsAuthentication;
}
}
Private Shared Function AuthenticationSchemeForClient(ByVal request As HttpListenerRequest) As AuthenticationSchemes
Console.WriteLine("Client authentication protocol selection in progress...")
' Do not authenticate local machine requests.
If request.RemoteEndPoint.Address.Equals(IPAddress.Loopback) Then
Return AuthenticationSchemes.None
Else
Return AuthenticationSchemes.IntegratedWindowsAuthentication
End If
End Function
实例使用此 HttpListener 类型的委托根据请求的特征选择身份验证方案。
委托 AuthenticationSchemeSelector 将为每个未提供身份验证信息的传入请求传递对象 HttpListenerRequest 。 委托调用的方法使用 HttpListenerRequest 对象和任何其他可用信息来确定需要哪种身份验证方案。 委托是使用 AuthenticationSchemeSelectorDelegate 属性指定的。
