推荐答案
您可以在导航到站点之前禁用缓存(包括cookie)。为此,可以使用 API函数并将 INTERNET_OPTION_SUPPRESS_BEHAVIOR(81)
选项的值设置为 INTERNET_SUPPRESS_COOKIE_PERSIST(3 )
值。
You can disable cache (including cookies) before navigating to the site. To do so, you can use InternetSetOption
API function and set the value of INTERNET_OPTION_SUPPRESS_BEHAVIOR(81)
option to INTERNET_SUPPRESS_COOKIE_PERSIST(3)
value.
示例
以下例如,工作方式类似于开始新的会话。虽然我在计算机上登录了 outlook.com
,但是当我打开此应用程序并浏览 outlook.com $ c $时c>禁用cookie和缓存后,它的工作方式类似于开始一个新会话,我需要登录到outlook.com:
The following example, works like starting a new session. While I've logged in to the outlook.com
on my machine, but when I open this application and browse outlook.com
after disabling cookies and cache, it works like starting a new session and I need to login to outlook.com:
//using System.Runtime.InteropServices;
[DllImport("wininet.dll", SetLastError = true, CharSet = CharSet.Auto)]
public static extern bool InternetSetOption(IntPtr hInternet, int dwOption,
IntPtr lpBuffer, int dwBufferLength);
private void Form1_Load(object sender, EventArgs e)
{
var ptr = Marshal.AllocHGlobal(4);
Marshal.WriteInt32(ptr, 3);
InternetSetOption(IntPtr.Zero, 81, ptr, 4);
Marshal.Release(ptr);
webBrowser1.Navigate("https://outlook.com");
}
