응답과 함께 반환된 쿠키의 컬렉션을 가져오거나 설정합니다.

public:
 property System::Net::CookieCollection ^ Cookies { System::Net::CookieCollection ^ get(); void set(System::Net::CookieCollection ^ value); };
public System.Net.CookieCollection Cookies { get; set; }
member this.Cookies : System.Net.CookieCollection with get, set
Public Property Cookies As CookieCollection

속성 값

CookieCollection

응답과 함께 전송된 쿠키가 들어 있는 CookieCollection입니다. 응답에 쿠키가 추가되지 않았으면 이 컬렉션은 비어 있습니다.

예제

다음 코드 예제에서는 쿠키에 대한 요청을 확인하고 요청에 쿠키가 없는 경우 응답과 함께 새 쿠키를 반환합니다.

// This example requires the System and System.Net namespaces.

public static string NextCustomerID()
{
    // A real-world application would do something more robust
    // to ensure uniqueness.
    return DateTime.Now.ToString();
}
public static void SimpleListenerCookieExample(string[] prefixes)
{
    // Create a listener.
    HttpListener listener = new HttpListener();
    // Add the prefixes.
    foreach (string s in prefixes)
    {
        listener.Prefixes.Add(s);
    }
    listener.IgnoreWriteExceptions = true;
    listener.Start();
    Console.WriteLine("Listening...");
    // Note: The GetContext method blocks while waiting for a request.
    HttpListenerContext context = listener.GetContext();
    HttpListenerRequest request = context.Request;
    string customerID = null;

    // Did the request come with a cookie?
    Cookie cookie = request.Cookies["ID"];
    if (cookie != null)
    {
         customerID=cookie.Value;
    }
    if (customerID !=null)
    {
          Console.WriteLine("Found the cookie!");
    }
    // Get the response object.
    HttpListenerResponse response = context.Response;
    // If they didn't provide a cookie containing their ID, give them one.
    if (customerID == null)
    {
        customerID = NextCustomerID();
        Cookie cook = new Cookie("ID", customerID );
        response.AppendCookie (cook);
    }
    // Construct a response.
    string responseString = "<HTML><BODY> Hello " + customerID + "!</BODY></HTML>";
    byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString);
    // Get the response stream and write the response to it.
    response.ContentLength64 = buffer.Length;
    System.IO.Stream output = response.OutputStream;
    output.Write(buffer,0,buffer.Length);
    // You must close the output stream.
    output.Close();
    // Closing the response sends the response to the client.
    response.Close();
    listener.Stop();

설명

쿠키는 로컬(클라이언트) 컴퓨터에 저장된 웹 서버의 이름/값 텍스트 데이터입니다. 지원되는 쿠키 형식은 Netscape, RFC 2109 및 RFC 2965입니다.
