Cookie.Secure 屬性

定義

命名空間:

System.Net

組件:

netstandard.dll, System.Net.Primitives.dll

來源:

Cookie.cs

取得或設定 Cookie 的安全層級。

public:
 property bool Secure { bool get(); void set(bool value); };

public bool Secure { get; set; }

member this.Secure : bool with get, set

Public Property Secure As Boolean

屬性值

Boolean

如果要求使用的是 HTTPS (Secure Hypertext Transfer Protocol)，且用戶端在後續的要求中只需傳回 Cookie，則為 true，否則，即為 false。 預設為 false。

範例

下列範例會顯示回應中傳回的 Cookie 屬性。 如需完整範例，請參閱 Cookie 類別主題。

var request = (HttpWebRequest)WebRequest.Create(args[0]);
request.CookieContainer = new CookieContainer();

using (var response = (HttpWebResponse) request.GetResponse())
{
    // Print the properties of each cookie.
    foreach (Cookie cook in response.Cookies)
    {
        Console.WriteLine("Cookie:");
        Console.WriteLine($"{cook.Name} = {cook.Value}");
        Console.WriteLine($"Domain: {cook.Domain}");
        Console.WriteLine($"Path: {cook.Path}");
        Console.WriteLine($"Port: {cook.Port}");
        Console.WriteLine($"Secure: {cook.Secure}");

        Console.WriteLine($"When issued: {cook.TimeStamp}");
        Console.WriteLine($"Expires: {cook.Expires} (expired? {cook.Expired})");
        Console.WriteLine($"Don't save: {cook.Discard}");
        Console.WriteLine($"Comment: {cook.Comment}");
        Console.WriteLine($"Uri for comments: {cook.CommentUri}");
        Console.WriteLine($"Version: RFC {(cook.Version == 1 ? 2109 : 2965)}");

        // Show the string representation of the cookie.
        Console.WriteLine($"String: {cook}");
    }
}

    Dim request As HttpWebRequest = WebRequest.Create(args(0))
    request.CookieContainer = New CookieContainer()

    Using response As HttpWebResponse = request.GetResponse()
        ' Print the properties of each cookie.
        For Each cook As Cookie In response.Cookies
            Console.WriteLine("Cookie:")
            Console.WriteLine($"{cook.Name} = {cook.Value}")
            Console.WriteLine($"Domain: {cook.Domain}")
            Console.WriteLine($"Path: {cook.Path}")
            Console.WriteLine($"Port: {cook.Port}")
            Console.WriteLine($"Secure: {cook.Secure}")

            Console.WriteLine($"When issued: {cook.TimeStamp}")
            Console.WriteLine($"Expires: {cook.Expires} (expired? {cook.Expired})")
            Console.WriteLine($"Don't save: {cook.Discard}")
            Console.WriteLine($"Comment: {cook.Comment}")
            Console.WriteLine($"Uri for comments: {cook.CommentUri}")
            Console.WriteLine($"Version: RFC {If(cook.Version = 1, 2109, 2965)}")

            ' Show the string representation of the cookie.
            Console.WriteLine($"String: {cook}")
        Next
    End Using

備註

實際上，當此屬性是 true 這個 Cookie 時，只能透過 https:// 要求傳送。
