HttpListenerResponse.SetCookie(Cookie) 方法
定义
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。
添加或更新随此响应发送的 Cookie 集合中的 Cookie。
public:
void SetCookie(System::Net::Cookie ^ cookie);public void SetCookie (System.Net.Cookie cookie);member this.SetCookie : System.Net.Cookie -> unitPublic Sub SetCookie (cookie As Cookie)参数
例外
cookie 为 null。
该 Cookie 已经在集合中，无法替换。
示例
下面的代码示例演示如何调用此方法。
// This example requires the System and System.Net namespaces.
public static void SimpleCookieExample(string[] 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;
// This application sends a cookie to the client marking the time
// they visited.
Cookie timeStampCookie = new Cookie("VisitDate", DateTime.Now.ToString());
// Obtain a response object.
HttpListenerResponse response = context.Response;
// Add the cookie to the response.
response.SetCookie(timeStampCookie);
// Construct a response.
string responseString = "<HTML><BODY> Hello world!</BODY></HTML>";
response.ContentEncoding = System.Text.Encoding.UTF8;
byte[] buffer = System.Text.Encoding.UTF8.GetBytes(responseString);
// Send the response.
response.Close(buffer, true);
listener.Stop();
}
' This example requires the System and System.Net namespaces.
Public Shared Sub SimpleCookieExample(ByVal prefixes As String())
' 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
' This application sends a cookie to the client marking the time
' they visited.
Dim timeStampCookie As Cookie = New Cookie("VisitDate", DateTime.Now.ToString())
' Obtain a response object.
Dim response As HttpListenerResponse = context.Response
' Add the cookie to the response.
response.SetCookie(timeStampCookie)
' Construct a response.
Dim responseString As String = "<HTML><BODY> Hello world!</BODY></HTML>"
response.ContentEncoding = System.Text.Encoding.UTF8
Dim buffer As Byte() = System.Text.Encoding.UTF8.GetBytes(responseString)
' Send the response.
response.Close(buffer, True)
listener.Stop()
End Sub
注解
如果两 Name个 Cookie 的 、 Domain和 Path 属性的值相同，则视为相同。 如果这三条信息相同，则 方法将尝试更新 Cookie。 名称和域比较不区分大小写，但路径比较区分大小写。
