按照本快速入门指南中的步骤操作,在大约 10 分钟内 一个简单的 Java 命令行应用,用于向零触摸 注册客户 API。
前提条件
如需运行本快速入门,您需要:
- 与您的零触摸注册客户相关联的服务账号 。请参阅获取 开始。
- Java 1.7 或更高版本。
- Gradle 2.3 或更高版本。
- 能够访问互联网和网络浏览器。
第 1 步:启用零触摸注册 API
- 使用此 向导,以在 Google Developers Console 中创建或选择项目。 系统会自动启用该 API。点击继续,然后点击前往凭据页面 。
- 将您要访问哪些数据?设置为应用数据。
- 点击下一步。系统应该会提示您创建 Service 。
- 为服务账号名称提供一个描述性名称。
- 记下服务账号 ID(看起来像是电子邮件地址),因为您将 稍后使用。
- 将角色设置为服务账号 >Service Account User。
- 点击完成以完成服务账号的创建过程。
- 点击您创建的服务账号的电子邮件地址。
- 点击 **Keys**。
- 点击 **Add key**,然后点击 **Create new key**。
- 对于 **密钥类型**,选择 **JSON**。
- 点击创建,私钥便会下载到您的计算机。
- 点击 **Close**。
- 将该文件移至您的工作目录中,并将其重命名为
service_account_key.json
。
第 2 步:准备项目
请按照以下步骤设置 Gradle 项目:
运行以下命令,在工作目录中创建一个新项目:
gradle init --type basic
mkdir -p src/main/java src/main/resources复制您在创建
service_account_key.json
服务账号复制到您之前创建的src/main/resources/
目录中。打开默认的
build.gradle
文件,并将其内容替换为以下代码:
apply plugin: 'java'
apply plugin: 'application'
mainClassName = 'CustomerQuickstart'
sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.api-client:google-api-client:2.2.0'
compile 'com.google.apis:google-api-services-androiddeviceprovisioning:v1-rev20230509-2.0.0'
compile 'com.google.auth:google-auth-library-oauth2-http:1.16.1'
compile 'com.google.auth:google-auth-library-credentials:1.16.1'
compile 'com.google.http-client:google-http-client:1.43.1'
compile 'com.google.oauth-client:google-oauth-client-jetty:1.34.1'
}
第 3 步:设置示例
创建一个名为 src/main/java/CustomerQuickstart.java
的文件,并将
代码并保存该文件。
