設定應用程式預設憑證

如要在 Vertex AI 上使用 Gemini，您需要使用 Google Cloud API 金鑰或應用程式預設憑證進行驗證。建議您使用 API 金鑰進行測試，並使用應用程式預設憑證進行實際作業。本頁說明如何設定應用程式預設憑證。

事前準備

選取專案、啟用帳單功能、啟用 Vertex AI API、安裝 gcloud CLI

Sign in to your Google Account.

If you don't already have one, sign up for a new account.

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

Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

Go to project selector

Verify that billing is enabled for your Google Cloud project.

Enable the Vertex AI API.

Enable the API

Install the Google Cloud CLI.

如果您使用外部識別資訊提供者 (IdP)，請先 使用聯合身分登入 gcloud CLI。

如要初始化 gcloud CLI，請執行下列指令：

gcloud init

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

Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

Go to project selector

Enable the API

Install the Google Cloud CLI.

如果您使用外部識別資訊提供者 (IdP)，請先 使用聯合身分登入 gcloud CLI。

如要初始化 gcloud CLI，請執行下列指令：

gcloud init

建立本機驗證憑證

Create local authentication credentials for your user account:

gcloud auth application-default login

If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.
