透過 Google 帳戶驗證使用者

這個頁面會逐步引導您部署 App Engine 標準或彈性環境應用程式,並使用 Identity-Aware Proxy (IAP) 保護其安全。本快速入門導覽課程包含 App Engine 標準環境網頁應用程式的程式碼範例,可驗證登入使用者的名稱;並使用 Cloud Shell 複製及部署應用程式範例。您可運用此快速入門導覽課程,啟用 App Engine 標準環境或彈性環境應用程式的 IAP。

若您預計從內容傳遞聯播網 (CDN) 提供資源,請參閱最佳做法指南取得重要資訊。

如果 App Engine 應用程式包含多項服務,您可以針對不同服務設定不同的 IAP 權限,包括只讓部分服務公開存取,同時保護其他服務。

逐步引導


事前準備

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

    Go to project selector

  3. Verify that billing is enabled for your Google Cloud project.

  4. In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

  5. Verify that billing is enabled for your Google Cloud project.

事前準備

如要為 App Engine 啟用 IAP,請先準備好下列項目:

  • 啟用計費功能的 Google Cloud 主控台專案。

如果您尚未設定 App Engine 執行個體,請參閱部署 App Engine 一文,取得完整逐步操作說明。

IAP 會使用 Google 代管的 OAuth 用戶端驗證使用者。只有機構內的使用者可以存取啟用 IAP 的應用程式。 如要允許機構外部使用者存取,請參閱「為外部應用程式啟用 IAP」。

啟用 IAP

控制台

使用 Google Cloud 控制台啟用 IAP 時,無法使用 Google 代管的 OAuth 用戶端。

Dynamic include file

If you haven't configured your project's OAuth consent screen, you'll be prompted to do so. To configure your OAuth consent screen, see Setting up your OAuth consent screen.

Setting up IAP access

  1. Go to the Identity-Aware Proxy page.
    Go to the Identity-Aware Proxy page
  2. Select the project you want to secure with IAP.
  3. Select the checkbox next to the resource you want to grant access to.
  4. On the right side panel, click Add principal.
  5. In the Add principals dialog that appears, enter the email addresses of groups or individuals who should have the IAP-secured Web App User role for the project.

    The following kinds of principals can have this role:

    • Google Account: user@gmail.com
    • Google Group: admins@googlegroups.com
    • Service account: server@example.gserviceaccount.com
    • Google Workspace domain: example.com

    Make sure to add a Google Account that you have access to.

  6. Select Cloud IAP > IAP-secured Web App User from the Roles drop-down list.
  7. Click Save.

Turning on IAP

  1. On the Identity-Aware Proxy page, under APPLICATIONS, find the application you want to restrict access to. To turn on IAP for a resource,
  2. In the Turn on IAP window that appears, click Turn On to confirm that you want IAP to secure your resource. After you turn on IAP, it requires login credentials for all connections to your load balancer. Only accounts with the IAP-Secured Web App User role on the project will be given access.

gcloud

您需要最新版的 gcloud CLI,才能設定專案和 IAP。如需安裝 gcloud CLI 的操作說明,請參閱「安裝 gcloud CLI」。

  1. 如要驗證,請使用 Google Cloud CLI 執行下列指令。
    gcloud auth login
  2. 點選畫面顯示的網址,然後登入。
  3. 登入之後,複製顯示的驗證碼並貼到指令列中。
  4. 執行下列指令,指定包含您要使用 IAP 保護的應用程式專案。
    gcloud config set project PROJECT_ID
  5. 如要啟用 IAP,請執行下列指令。
    gcloud iap web enable --resource-type=app-engine --versions=version
  6. 將應擁有「IAP-Secured Web App User」(受 IAP 保護的網路應用程式使用者) 角色的主體新增至專案。
    gcloud projects add-iam-policy-binding PROJECT_ID \
           --member=PRINCIPAL_IDENTIFIER \
           --role=roles/iap.httpsResourceAccessor
    • PROJECT_ID 替換為您的專案 ID。
    • 請將 PRINCIPAL_IDENTIFIER 替換為必要的管理者。這可以是網域、群組、服務帳戶或使用者的類型。例如 user:myemail@example.com

啟用 IAP 後,您可以使用 gcloud CLI 以 IAM 角色 roles/iap.httpsResourceAccessor 修改 IAP 存取權政策。進一步瞭解如何管理角色和權限

API

  1. Run the following command to prepare a settings.json file.

    cat << EOF > settings.json
    {
    "iap":
      {
        "enabled":true
      }
    }
    EOF
    

  2. Run the following command to enable IAP.

    curl -X PATCH \
    -H "Authorization: Bearer $(gcloud auth print-access-token)" \
    -H "Accept: application/json" \
    -H "Content-Type: application/json" \
    -d @settings.json \
    "https://appengine.googleapis.com/v1/apps/PROJECT_ID?updateMask=iap"
    

After you enable IAP, you can use the Google Cloud CLI to modify the IAP access policy using the IAM role roles/iap.httpsResourceAccessor. Learn more about managing roles and permissions.

測試使用者驗證

  1. 如要存取應用程式網址,請使用您新增至 IAP 的 Google 帳戶,並指派「受 IAP 保護的網頁應用程式使用者」角色,您對應用程式的存取權應不受限制。

  2. 使用 Chrome 的無痕式視窗存取應用程式,並在系統提示時登入。如果您嘗試使用未經授權的帳戶存取應用程式,並具備 IAP 安全網頁應用程式使用者角色,系統會顯示訊息,說明您沒有存取權。
