准备工作

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.
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
Create or select 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.
• Create a Google Cloud project:

  gcloud projects create PROJECT_ID

  Replace PROJECT_ID with a name for the Google Cloud project you are creating.

• Select the Google Cloud project that you created:

  gcloud config set project PROJECT_ID

  Replace PROJECT_ID with your Google Cloud project name.
Verify that billing is enabled for your Google Cloud project.
Enable the DLP API:
gcloud services enable dlp.googleapis.com
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.
Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/dlp.user
gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE
Replace the following:
• PROJECT_ID: your project ID.
• USER_IDENTIFIER: the identifier for your user account—for example, [e-mail].
• ROLE: the IAM role that you grant to your user account.

Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/dlp.user

gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

Replace the following:

• PROJECT_ID: your project ID.
• USER_IDENTIFIER: the identifier for your user account—for example, [e-mail].
• ROLE: the IAM role that you grant to your user account.
1. 安装 Node.js 和 NPM。

设置 Sensitive Data Protection CLI 应用

如需使用 Node.js 设置 Sensitive Data Protection CLI 应用，请执行以下操作：

1. 克隆 Node.js DLP 客户端库：

    git clone https://github.com/GoogleCloudPlatform/nodejs-docs-samples
   

2. 导航到 dlp 目录。

    cd nodejs-docs-samples/dlp
   

3. 安装应用依赖项：

    npm install
   

检查字符串是否存在敏感信息

如需使用 DLP API 和 inspectString Node.js 脚本扫描示例文本，请运行以下命令：

  node inspectString.js PROJECT_ID "My email address is [e-mail]."

输出类似于以下内容：

  Findings:
      Info type: EMAIL_ADDRESS
      Likelihood: LIKELY

清理

为避免因本页面中使用的资源导致您的 Google Cloud 账号产生费用，请删除包含这些资源的 Google Cloud 项目。

删除项目

如果您为此快速入门创建了新项目，那么防止产生额外费用的最简单方法是删除该项目。

警告：删除项目会产生以下影响：

• 项目中的所有内容都会被删除。如果您将现有项目用于本文档中的任务，则删除该项目后，还将删除您已在该项目中完成的任何其他工作。
• 自定义项目 ID 丢失。创建此项目时，您可能创建了要在将来使用的自定义项目 ID。要保留使用该项目 ID 的网址（例如 appspot.com 网址），请删除项目内的所选资源，而不是删除整个项目。

如果您打算探索多个架构、教程或快速入门，则重复使用项目可以帮助您避免超出项目配额限制。

Delete a Google Cloud project:

gcloud projects delete PROJECT_ID

撤消凭据

1. Optional: Revoke the authentication credentials that you created, and delete the local credential file.

   gcloud auth application-default revoke

2. Optional: Revoke credentials from the gcloud CLI.

   gcloud auth revoke
