範例

下列程式碼範例將示範如何呼叫這個方法, Forbidden以將 (403) 回應傳送至用戶端。The following code example demonstrates calling this method to send a Forbidden (403) response to the client.

static string message403;
static HttpListenerResponse preMade403Response;
static void SendBadCertificateResponse(HttpListenerResponse response)
{
    if (preMade403Response == null)
    {
        // Set up an authentication error response template.
        response.StatusCode = (int)HttpStatusCode.Forbidden;
        response.StatusDescription = "403 Forbidden";
        response.ProtocolVersion = new Version("1.1");
        response.SendChunked = false;

        preMade403Response = response;
    }
    else
    {
        response.CopyFrom(preMade403Response);
    }

    // The response body cannot be saved in the template.

    StringBuilder message = new StringBuilder();
    message.Append("<HTML><BODY>");
    message.Append("<p> Error message 403: Access is denied due to a missing or invalid client certificate.</p>");
    message.Append("</BODY></HTML>");
    message403 = message.ToString();

    // Turn the error message into a byte array using the 
    // encoding from the response when present.
    System.Text.Encoding encoding = response.ContentEncoding;
    if (encoding == null)
    {
        encoding = System.Text.Encoding.UTF8;
        response.ContentEncoding = encoding;
    }

    byte[] buffer = encoding.GetBytes(message403);
    response.ContentLength64 = buffer.Length;
    // Write the error message.
    System.IO.Stream stream = response.OutputStream;
    stream.Write(buffer, 0, buffer.Length);
    // Send the response.
    response.Close();
}
Private Shared message403 As String
Private Shared preMade403Response As HttpListenerResponse
Private Shared Sub SendBadCertificateResponse(ByVal response As HttpListenerResponse)
    
    If preMade403Response Is Nothing Then
        ' Set up an authentication error response template.
        response.StatusCode = Cint(HttpStatusCode.Forbidden)
        response.StatusDescription = "403 Forbidden"
        response.ProtocolVersion = New Version("1.1")
        response.SendChunked = False
    Else
        response.CopyFrom(preMade403Response) 
    End If
    
    ' The response body cannot be saved in the template.
    Dim message As New StringBuilder()
    message.Append("<HTML><BODY>")
    message.Append("<p> Error message 403: Access is denied due to a missing or invalid client certificate.</p>")
    message.Append("</BODY></HTML>")
    message403 = message.ToString()

    ' Turn the error message into a byte array using the 
    ' encoding from the response when present.
    Dim encoding As System.Text.Encoding = response.ContentEncoding
    If encoding Is Nothing Then
        encoding = System.Text.Encoding.UTF8
        response.ContentEncoding = encoding
    End If

    Dim buffer() As Byte = encoding.GetBytes(message403)
    response.ContentLength64 = buffer.Length
    ' Write the error message.
    Dim stream As System.IO.Stream = response.OutputStream
    stream.Write(buffer, 0, buffer.Length)
    ' Send the response.
    response.Close()
End Sub

備註

這個方法會關閉回應資料流程和與HttpListenerRequest回應相關聯的。This method closes the response stream and the HttpListenerRequest associated with the response.

Close(Byte[], Boolean) Close(Byte[], Boolean) Close(Byte[], Boolean) Close(Byte[], Boolean)

將指定的位元組陣列傳回至用戶端,並釋放這個 HttpListenerResponse 執行個體所持有的資源。Returns the specified byte array to the client and releases the resources held by this HttpListenerResponse instance.

public:
 void Close(cli::array <System::Byte> ^ responseEntity, bool willBlock);
public void Close (byte[] responseEntity, bool willBlock);
member this.Close : byte[] * bool -> unit
Public Sub Close (responseEntity As Byte(), willBlock As Boolean)

參數

responseEntity
Byte[]

Byte 陣列,包含要傳送至用戶端的回應。A Byte array that contains the response to send to the client.

willBlock
Boolean Boolean Boolean Boolean

true 表示在清除資料流到用戶端時封鎖執行,否則為 falsetrue to block execution while flushing the stream to the client; otherwise, false.

範例

下列程式碼範例將示範如何呼叫這個方法。The following code example demonstrates calling this method.

// This example requires the System and System.Net namespaces.
public static void SimpleListenerExample2(string[] prefixes)
{
    // URI prefixes are required,
    // for example "http://contoso.com:8080/index/".
    if (prefixes == null || prefixes.Length == 0)
      throw new ArgumentException("prefixes");
    
    // Create a listener.
    HttpListener listener = new HttpListener();
    // Add the prefixes.
    foreach (string s in prefixes)
    {
        listener.Prefixes.Add(s);
    }
    listener.Start();
    Console.WriteLine("Listening...");
    // Note: The GetContext method 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 responseString = "<HTML><BODY> Hello world!</BODY></HTML>";
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString);
    // Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length;
    // Demonstrate using the close overload that takes an 
    // entity body.
    // Specify true to block while data is transmitted.
    response.Close(buffer, true);
    listener.Stop();
}
Public Shared Sub SimpleListenerExample2(ByVal prefixes As String())
    ' URI prefixes are required,
    ' for example "http://contoso.com:8080/index/".
    If prefixes Is Nothing Or prefixes.Length = 0 Then
        Throw New ArgumentException("prefixes")
    End If

    ' Create a listener
    Dim listener As HttpListener = New HttpListener()
    ' Add the prefixes
    For Each s As String In prefixes
        listener.Prefixes.Add(s)
    Next

    listener.Start()
    Console.WriteLine("Listening...")
    ' Note: The GetContext method 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
    ' Construct a response
    Dim responseString As String = "<HTML><BODY> Hello world!</BODY></HTML>"
    Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString)
    ' Get a response stream and write the response to it.
    response.ContentLength64 = buffer.Length
    ' Demonstrate using the close overload that takes an 
    ' entity body.
    ' Specify true to block while data Is transmitted.
    response.Close(buffer, True)
    listener.Stop()
End Sub

備註

如果您要使用回應來傳送本文資料, 您可以使用這個方法將它Byte當做陣列, 而不是將主體資料OutputStream寫入屬性並呼叫Close方法。If you are sending body data with the response, you can use this method to send it as a Byte array instead of writing the body data to the OutputStream property and calling the Close method.

這個方法會關閉回應資料流程和與HttpListenerRequest回應相關聯的。This method closes the response stream and the HttpListenerRequest associated with the response.
