예제

다음 코드 예제에서는 응답에 쿠키를 추가 하는 방법을 보여 줍니다.The following code example demonstrates adding a cookie to a response

// 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

이 메서드를 호출 하는 것은 Cookies 속성에서 반환 된 컬렉션에 대해 Add 메서드를 호출 하는 것과 같습니다.Calling this method is equivalent to calling the Add method on the collection returned by the Cookies property.

지정 된 쿠키가 Cookies 속성의 컬렉션에 없으면 cookie 추가 됩니다.If the specified cookie does not exist in the Cookies property's collection, cookie is added. 쿠키가 컬렉션에 있으면 cookie 바꿉니다.If the cookie exists in the collection, cookie replaces it.
