Secret Manager 客户端库

本页介绍了如何开始使用 Secret Manager API 的 Cloud 客户端库。通过客户端库,您可以更轻松地使用支持的语言访问 Google Cloud API。虽然您可以通过向服务器发出原始请求来直接使用 Google Cloud API,但客户端库可实现简化,从而显著减少您需要编写的代码量。

请参阅客户端库说明,详细了解 Cloud 客户端库和旧版 Google API 客户端库。

安装客户端库

C++

如需详细了解此客户端库的要求和安装依赖项,请参阅设置 C++ 开发环境

C#

如果您使用的是 Visual Studio 2017 或更高版本,请打开 nuget 软件包管理器窗口并输入以下内容:

Install-Package Google.Apis

如果您使用 .NET Core 命令行界面工具来安装依赖项,请运行以下命令:

dotnet add package Google.Apis

如需了解详情,请参阅设置 C# 开发环境

Go

$ go get cloud.google.com/go/secretmanager/apiv1
$ go get google.golang.org/genproto/googleapis/cloud/secretmanager/v1

如需了解详情,请参阅设置 Go 开发环境

Java

If you are using Maven, add the following to your pom.xml file. For more information about BOMs, see The Google Cloud Platform Libraries BOM.

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.cloud</groupId>
      <artifactId>libraries-bom</artifactId>
      <version>26.50.0</version>
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>

<dependencies>
  <dependency>
    <groupId>com.google.cloud</groupId>
    <artifactId>google-cloud-secretmanager</artifactId>
  </dependency>
</dependencies>

If you are using Gradle, add the following to your dependencies:

implementation 'com.google.cloud:google-cloud-secretmanager:2.53.0'

If you are using sbt, add the following to your dependencies:

libraryDependencies += "com.google.cloud" % "google-cloud-secretmanager" % "2.53.0"

If you're using Visual Studio Code, IntelliJ, or Eclipse, you can add client libraries to your project using the following IDE plugins:

The plugins provide additional functionality, such as key management for service accounts. Refer to each plugin's documentation for details.

如需了解详情,请参阅设置 Java 开发环境

Node.js

$ npm install --save @google-cloud/secret-manager

如需了解详情,请参阅设置 Node.js 开发环境

PHP

composer require google/apiclient

如需了解详情,请参阅在 Google Cloud 上使用 PHP

Python

$ pip install google-cloud-secret-manager

如需了解详情,请参阅设置 Python 开发环境

Ruby

gem install google-api-client

如需了解详情,请参阅设置 Ruby 开发环境

设置身份验证

为了对 Google Cloud API 的调用进行身份验证,客户端库支持应用默认凭据 (ADC);这些库会在一组指定的位置查找凭据,并使用这些凭据对发送到 API 的请求进行身份验证。借助 ADC,您可以在各种环境(例如本地开发或生产环境)中为您的应用提供凭据,而无需修改应用代码。

对于生产环境,设置 ADC 的方式取决于服务和上下文。如需了解详情,请参阅设置应用默认凭据

对于本地开发环境,您可以使用与您的 Google 账号关联的凭据设置 ADC:

  1. Install the Google Cloud CLI, then initialize it by running the following command:

    gcloud init
  2. If you're using a local shell, then create local authentication credentials for your user account:

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

    登录屏幕随即出现。在您登录后,您的凭据会存储在 ADC 使用的本地凭据文件中。

使用客户端库

以下示例展示了如何使用客户端库。

Go


// Sample quickstart is a basic program that uses Secret Manager.

	"cloud.google.com/go/secretmanager/apiv1/secretmanagerpb"
	"google.golang.org/api/option"
)

func main() {
	// GCP project in which to store secrets in Secret Manager.
	projectID := "your-project-id"
	// Location at which you want to store your secrets
	locationID := "your-location-id"

	// Create the client.
	ctx := context.Background()
	endpoint := fmt.Sprintf("secretmanager.%s.rep.googleapis.com:443", locationID)

	}

	// Declare the payload to store.
	payload := []byte("my super secret data")

	// Build the request.
	addSecretVersionReq := &secretmanagerpb.AddSecretVersionRequest{

	}

	// Build the request.
	accessRequest := &secretmanagerpb.AccessSecretVersionRequest{
		Name: version.Name,
	}

	// Call the API.
	result, err := client.AccessSecretVersion(ctx, accessRequest)
	if err != nil {
		log.Fatalf("failed to access secret version: %v", err)
	}

	// Print the secret payload.
	//
	// WARNING: Do not print the secret in a production environment - this
	// snippet is showing how to access the secret material.
	log.Printf("Plaintext: %s", result.Payload.Data)
