範例

使用 C 的桌面應用程式#

針對傳統型應用程式，您不需要呼叫 UserConsentVerifier.RequestVerificationAsync 方法，而是需要：

首先， (HWND) 擷取視窗句柄。該主題包含 Windows UI 連結庫 (WinUI) 3、Windows Presentation Foundation (WPF) ，以及 Windows Forms (WinForms) 的程式代碼範例。將該程式代碼插入下列程式代碼清單中。
然後呼叫 Windows.Security.Credentials.UI.UserConsentVerifierInterop C# Interop 類別的 RequestVerificationForWindowAsync 方法。如需 C# Interop 類別的詳細資訊，請參閱從 .NET 應用程式呼叫 Interop API。另請參閱顯示相依於 CoreWindow 的 WinRT UI 物件。

private async System.Threading.Tasks.Task<string> RequestConsent(string userMessage)
{
    string returnMessage;

    // Retrieve the window handle of the current WinUI 3 window.
    var hwnd = WinRT.Interop.WindowNative.GetWindowHandle(this);

    // Use the interop interface to request the logged on user's consent via device authentication
    var consentResult = await Windows.Security.Credentials.UI.UserConsentVerifierInterop.RequestVerificationForWindowAsync(hwnd, userMessage);

    switch (consentResult)
    {
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.Verified:
            returnMessage = "User verified.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.DeviceBusy:
            returnMessage = "Authentication device is busy.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.DeviceNotPresent:
            returnMessage = "No authentication device found.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.DisabledByPolicy:
            returnMessage = "Authentication device verification is disabled by policy.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.NotConfiguredForUser:
            returnMessage = "Please go to Account Settings to set up PIN or other advanced authentication.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.RetriesExhausted:
            returnMessage = "There have been too many failed attempts. Device authentication canceled.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.Canceled:
            returnMessage = "Device authentication canceled.";
            break;
        default:
            returnMessage = "Authentication device is currently unavailable.";
            break;
    }

    return returnMessage;
}

使用 C 通用 Windows 平台 (UWP) 應用程式#

此程式代碼範例適用於通用 Windows 平台 (UWP) app。它會顯示指紋驗證的要求，後面接著傳回描述結果的訊息。程序代碼會呼叫適用於UWP app的 UserConsentVerifier.RequestVerificationAsync 方法。

private async System.Threading.Tasks.Task<string> RequestConsent(string userMessage)
{
    string returnMessage;

    // Request the logged on user's consent via authentication device.
    var consentResult = await Windows.Security.Credentials.UI.UserConsentVerifier.RequestVerificationAsync(userMessage);

    switch (consentResult)
    {
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.Verified:
            returnMessage = "User verified.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.DeviceBusy:
            returnMessage = "Authentication device is busy.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.DeviceNotPresent:
            returnMessage = "No authentication device found.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.DisabledByPolicy:
            returnMessage = "Authentication device verification is disabled by policy.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.NotConfiguredForUser:
            returnMessage = "Please go to Account Settings to set up PIN or other advanced authentication.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.RetriesExhausted:
            returnMessage = "There have been too many failed attempts. Device authentication canceled.";
            break;
        case Windows.Security.Credentials.UI.UserConsentVerificationResult.Canceled:
            returnMessage = "Device authentication canceled.";
            break;
        default:
            returnMessage = "Authentication device is currently unavailable.";
            break;
    }
    return returnMessage;
}

使用 C++/WinRT 的桌面應用程式

針對傳統型應用程式，您不需要呼叫 UserConsentVerifier.RequestVerificationAsync 方法，而是需要：

首先取得將要求驗證之視窗的句柄。如需如何針對 Windows UI 連結庫 (WinUI) 3 執行這項操作的詳細資訊，請參閱擷取 (HWND) 視窗句柄。
取得 Windows.Security.Credentials.UI.UserConsentVerifier 對象的啟用處理站。
呼叫 IUserConsentVerifierInterop Interop 介面的 RequestVerificationForWindowAsync 方法。

winrt::Windows::Foundation::IAsyncOperation<winrt::hstring> MainWindow::RequestConsent(winrt::hstring userMessage)
{
    auto lifetime = get_strong();

    winrt::hstring returnMessage;

    // Retrieve the window handle of the current WinUI 3 window.
    HWND hwnd;
    winrt::check_hresult(m_inner->as<::IWindowNative>()->get_WindowHandle(&hwnd));

    // Use the interop interface to request the logged on user's consent via device authentication
    auto interop = winrt::get_activation_factory<winrt::Windows::Security::Credentials::UI::UserConsentVerifier, ::IUserConsentVerifierInterop>();
    auto consentResult =
        co_await winrt::capture<winrt::Windows::Foundation::IAsyncOperation<winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult>>(
            interop, &::IUserConsentVerifierInterop::RequestVerificationForWindowAsync, hwnd, reinterpret_cast<HSTRING>(winrt::get_abi(userMessage))));

    switch (consentResult)
    {
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::Verified:
            returnMessage = L"User verified.";
            break;
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::DeviceBusy:
            returnMessage = L"Authentication device is busy.";
            break;
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::DeviceNotPresent:
            returnMessage = L"No authentication device found.";
            break;
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::DisabledByPolicy:
            returnMessage = L"Authentication device verification is disabled by policy.";
            break;
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::NotConfiguredForUser:
            returnMessage = L"Please go to Account Settings to set up PIN or other advanced authentication.";
            break;
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::RetriesExhausted:
            returnMessage = L"There have been too many failed attempts. Device authentication canceled.";
            break;
        case winrt::Windows::Security::Credentials::UI::UserConsentVerificationResult::Canceled:
            returnMessage = L"Device authentication canceled.";
            break;
        default:
            returnMessage = L"Authentication device is currently unavailable.";
            break;
    }

    co_return returnMessage;
}

備註

您可以使用 UserConsentVerifier 來增強應用程式的安全性，方法是在使用者需要同意特定動作時包含驗證要求。例如，您可以先要求指紋驗證，再授權應用程式內購買或存取受限制的資源。您可以使用 UserConsentVerifier ，使用 CheckAvailabilityAsync 方法來判斷目前電腦是否支援指紋驗證，然後使用 RequestVerificationAsync 方法向指紋掃描要求使用者同意。

方法

CheckAvailabilityAsync()	檢查是否有可用的驗證裝置，例如 Microsoft Passport PIN、Windows Hello 或指紋讀取器。
RequestVerificationAsync(String)	使用驗證裝置執行驗證，例如 Microsoft Passport PIN、Windows Hello 或指紋讀取器。此 API 適用於通用 Windows 平台 (UWP) 應用程式。在 UserConsentVerifier 類別的範例中，會說明用於傳統型應用程式的替代 API。
