我需要在C#应用程序中为托管的WebBrowser控件创建自定义安全管理器。托管的WebBrowser控件应独立于IE安全和隐私设置。
问题:如果IE隐私设置设置为“高”,则依赖于cookie的网站在托管的WebBrowser控件中无法正常运行(如果隐私设置设置为“中”,则网站可以正常工作)。
托管WebBrowser控件的winform为GetSecurityId,MapUrlToZone和ProcessUrlAction提供了以下实现。 ProcessUrlAction由嵌入式浏览器调用,用于URL操作,如ACTIVEX_RUN,SCRIPT_RUN;但它没有被要求任何cookie相关的网址操作。
有没有办法为网页浏览器控件启用Cookie?或者下面的代码有问题吗?
private void InitBrowserSecurityData()
{
securityID = new byte[MAX_SIZE_SECURITY_ID];
securityID[0] = (byte)'f';
securityID[1] = (byte)'i';
securityID[2] = (byte)'l';
securityID[3] = (byte)'e';
securityID[4] = (byte)':';
securityID[5] = 0;
securityID[6] = 3;
securityID[7] = 0;
securityID[8] = 0;
securityID[9] = 0;
}
//GetSecurityId
int IInternetSecurityManager.GetSecurityId(string pwszUrl, IntPtr pbSecurityId, ref uint pcbSecurityId, ref uint dwReserved)
{
if (pcbSecurityId >= MAX_SIZE_SECURITY_ID)
{
Marshal.Copy(securityID, 0, pbSecurityId, MAX_SIZE_SECURITY_ID);
pcbSecurityId = 9;
return HResults.S_OK;
}
return (int)WinInetErrors.INET_E_DEFAULT_ACTION;
}
//MapUrlToZone
int IInternetSecurityManager.MapUrlToZone(string pwszUrl, out uint pdwZone, uint dwFlags)
{
pdwZone = (uint)tagURLZONE.URLZONE_LOCAL_MACHINE;
return HResults.S_OK;
}
//ProcessUrlAction
int IInternetSecurityManager.ProcessUrlAction(string pwszUrl, uint dwAction, IntPtr pPolicy,
uint cbPolicy, IntPtr pContext, uint cbContext, uint dwFlags, uint dwReserved)
{
URLACTION action = (URLACTION)dwAction;
bool hasUrlPolicy = (cbPolicy >= unchecked((uint)Marshal.SizeOf(typeof(int))));
URLPOLICY urlPolicy = (hasUrlPolicy) ? (URLPOLICY)Marshal.ReadInt32(pPolicy) : URLPOLICY.ALLOW;
bool hasContext = (cbContext >= unchecked((uint)Marshal.SizeOf(typeof(Guid))));
Guid context = (hasContext) ? (Guid)Marshal.PtrToStructure(pContext, typeof(Guid)) : Guid.Empty;
//all URL actions are allowed
if (hasUrlPolicy)
{
urlPolicy = URLPOLICY.ALLOW;
Marshal.WriteInt32(pPolicy, (int)urlPolicy);
return HResults.S_OK;
}
return (int)WinInetErrors.INET_E_DEFAULT_ACTION;
}
我已经看过这些问题,但它们对我不起作用。

Custom IInternetSecurityManager not being called with dialogs
答案 0 :(得分:1)
似乎Internet Explorer没有将Cookie操作传递给IInternetSecurityManager。这就是在嵌入式浏览器控件中难以覆盖IE隐私设置的原因。一些聪明的人已经很久以前就已经认识到了这一点here
