配置应用默认凭据

如需使用 Vertex AI 上的 Gemini，您需要使用Google Cloud API 密钥或应用默认凭证进行身份验证。我们建议使用 API 密钥进行测试，并使用应用默认凭证进行生产。本页面介绍了如何配置应用默认凭证。

准备工作

选择项目、启用结算功能、启用 Vertex AI API、安装 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.

如果您使用的是外部身份提供方 (IdP)，则必须先使用联合身份登录 gcloud CLI。

如需初始化 gcloud CLI，请运行以下命令：

gcloud init

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

如需初始化 gcloud CLI，请运行以下命令：

gcloud init

创建本地身份验证凭证

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.

发出您的第一个 API 请求
