示例

下面的代码示例演示如何创建对象并将其添加到 CodeConnectAccessNetCodeGroup。

static void SetNetCodeGroupAccess()
{
    String^ userPolicyLevel = "User";
    // Locate the User policy level.
    PolicyLevel^ level = nullptr;
    System::Collections::IEnumerator^ ph = 
        System::Security::SecurityManager::PolicyHierarchy();
    while(ph->MoveNext())
    {
        level = (PolicyLevel^)ph->Current;
        if (level->Label == userPolicyLevel)
        {
            break;       
        }
    }
    if (level->Label != userPolicyLevel)
        throw gcnew ApplicationException("Could not find User policy level.");

    IMembershipCondition^ membership =
        gcnew UrlMembershipCondition("http://www.contoso.com/*");
    NetCodeGroup^ codeGroup = gcnew NetCodeGroup(membership);
    // Delete default settings.
    codeGroup->ResetConnectAccess();
    // Create an object that represents access to the FTP scheme and 
    // default port.
    CodeConnectAccess^ CodeAccessFtp = 
        gcnew CodeConnectAccess(Uri::UriSchemeFtp, 
        CodeConnectAccess::DefaultPort);
    // Create an object that represents access to the HTTPS scheme 
    // and default port.
    CodeConnectAccess^ CodeAccessHttps = 
        gcnew CodeConnectAccess(Uri::UriSchemeHttps, 
        CodeConnectAccess::DefaultPort);
    // Create an object that represents access to the origin 
    // scheme and port.
    CodeConnectAccess^ CodeAccessOrigin = 
        CodeConnectAccess::CreateOriginSchemeAccess
        (CodeConnectAccess::OriginPort);
    // Add connection access objects to the NetCodeGroup object.
    codeGroup->AddConnectAccess(Uri::UriSchemeHttp, CodeAccessFtp);
    codeGroup->AddConnectAccess(Uri::UriSchemeHttp, CodeAccessHttps);
    codeGroup->AddConnectAccess(Uri::UriSchemeHttp, CodeAccessOrigin);
    // Provide name and description information for caspol.exe tool.
    codeGroup->Name = "ContosoHttpCodeGroup";
    codeGroup->Description = "Code originating from contoso.com can" +
        " connect back using the FTP or HTTPS.";
    // Add the code group to the User policy's root node.
    level->RootCodeGroup->AddChild(codeGroup);
    // Save the changes to the policy level.
    System::Security::SecurityManager::SavePolicy();
}

public static void SetNetCodeGroupAccess()
{
    const string userPolicyLevel = "User";
    // Locate the User policy level.
    PolicyLevel level = null;
    System.Collections.IEnumerator ph =
        System.Security.SecurityManager.PolicyHierarchy();
    while(ph.MoveNext())
    {
        level = (PolicyLevel)ph.Current;
        if( level.Label == userPolicyLevel )
        {
            break;
        }
    }
    if (level.Label != userPolicyLevel)
        throw new ApplicationException("Could not find User policy level.");

    IMembershipCondition membership =
        new UrlMembershipCondition(@"http://www.contoso.com/*");
    NetCodeGroup codeGroup = new NetCodeGroup(membership);
    // Delete default settings.
    codeGroup.ResetConnectAccess();
    // Create an object that represents access to the FTP scheme and default port.
    CodeConnectAccess a1 = new CodeConnectAccess(Uri.UriSchemeFtp, CodeConnectAccess.DefaultPort);
    // Create an object that represents access to the HTTPS scheme and default port.
    CodeConnectAccess a2 = new CodeConnectAccess(Uri.UriSchemeHttps, CodeConnectAccess.DefaultPort);
    // Create an object that represents access to the origin scheme and port.
    CodeConnectAccess a3 = CodeConnectAccess.CreateOriginSchemeAccess(CodeConnectAccess.OriginPort);
    // Add connection access objects to the NetCodeGroup object.
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a1);
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a2);
    codeGroup.AddConnectAccess(Uri.UriSchemeHttp, a3);
    // Provide name and description information for caspol.exe tool.
    codeGroup.Name = "ContosoHttpCodeGroup";
    codeGroup.Description = "Code originating from contoso.com can connect back using the FTP or HTTPS.";
    // Add the code group to the User policy's root node.
    level.RootCodeGroup.AddChild(codeGroup);
    // Save the changes to the policy level.
    System.Security.SecurityManager.SavePolicy();
}

注解

可以为同一origin scheme个 添加多个 CodeConnectAccess 对象。 origin scheme如果 已具有一个或多个关联CodeConnectAccess对象，则null指定 为 connectAccess 不起作用。 如果源方案没有关联的 CodeConnectAccess 对象，则 null 指定 为 connectAccess 将阻止具有匹配 originScheme 的源方案的代码访问其源服务器。
