Siga as etapas deste guia de início rápido e, em cerca de 10 minutos, você terá
um app de linha de comando Java simples que faz solicitações à API para revendedores do
registro sem toque.
Pré-requisitos
Para executar este guia de início rápido, você vai precisar de:
- Uma Conta do Google que faça parte da sua conta de revendedor do registro sem toque. Se você ainda não fez a integração, siga as etapas em Primeiros passos no guia do portal do revendedor.
- Java 1.7 ou superior.
- Gradle 2.3 ou mais recente.
- Acesso à Internet e a um navegador da Web.
Etapa 1: ativar a API de registro sem toque
- Use este
assistente para criar ou selecionar um projeto no Google Developers Console e
ativar a API automaticamente. Clique em Continuar e em Acessar credenciais
.
- Defina Quais dados você vai acessar? como Dados do aplicativo.
- Clique em Próxima. Você vai receber uma solicitação para criar uma conta de serviço.
- Dê um nome descritivo para Nome da conta de serviço.
- Anote o ID da conta de serviço (parece um endereço de e-mail), porque você vai precisar dele mais tarde.
- Defina o Papel como Contas de serviço > Usuário da conta de serviço.
- Clique em Concluído para terminar a criação da conta de serviço.
- Clique no endereço de e-mail da conta de serviço que você criou.
- Clique em **Chaves**.
- Clique em **Adicionar chave** e em **Criar nova chave**.
- Em **Tipo de chave**, selecione **JSON**.
- Clique em Criar, e a chave privada será salva no seu computador.
- Clique em **Fechar**.
- Mova o arquivo para o diretório de trabalho e renomeie-o como
service_account_key.json.
Etapa 2: vincular a conta de serviço
- Abra o portal do registro sem toque. Talvez seja necessário fazer login.
- Clique em settings_ethernet Contas de
serviço.
- Clique em add Vincular conta de serviço.
- Defina Endereço de e-mail como o endereço da conta de serviço que você criou.
- Clique em Vincular conta de serviço para usar a conta de serviço com sua conta de inscrição
sem contato.
Etapa 3: preparar o projeto
Siga as etapas abaixo para configurar seu projeto do Gradle:
Execute o seguinte comando para criar um novo projeto no diretório de trabalho:
gradle init --type basic
mkdir -p src/main/java src/main/resources
Copie o arquivo service_account_key.json que você salvou na etapa 1 para o
diretório src/main/resources/ criado acima.
Abra o arquivo build.gradle padrão e substitua o conteúdo por este
código:
apply plugin: 'java'
apply plugin: 'application'
mainClassName = 'ResellerQuickstart'
sourceCompatibility = 1.7
targetCompatibility = 1.7
version = '1.0'
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.api-client:google-api-client:1.30.11'
compile 'com.google.apis:google-api-services-androiddeviceprovisioning:+'
compile 'com.google.oauth-client:google-oauth-client-jetty:+'
}
Etapa 4: configurar o exemplo
Crie um arquivo chamado src/main/java/ResellerQuickstart.java, copie o código a seguir e salve o arquivo. Insira seu próprio ID de parceiro
de revenda como o valor de PARTNER_ID (a primeira linha do app).
import com.google.api.client.auth.oauth2.Credential;
import com.google.api.client.googleapis.auth.oauth2.GoogleCredential;

// Send an API request to list all our customers.
AndroidProvisioningPartner.Partners.Customers.List request =
service.partners().customers().list(PARTNER_ID);
ListCustomersResponse response = request.execute();
// Print out the details of each customer.
if (response.getCustomers() != null) {
java.util.List<Company> customers = response.getCustomers();
for (Company customer : customers) {
System.out.format("Name:%s ID:%d\n",
customer.getCompanyName(),
customer.getCompanyId());
}
} else {
System.out.println("No customers found");
}
}
}
ID do parceiro
As chamadas de API geralmente precisam do seu ID de parceiro de revendedor como argumento. Para encontrar o
ID do parceiro no portal de registro sem toque, siga as etapas abaixo:
- Abra o portal. Talvez seja necessário fazer login.
- Clique em settings_ethernet Contas de serviço.
- Copie o número do ID do parceiro na linha Seu ID de revendedor.
Etapa 5: executar o exemplo
Use a ajuda do sistema operacional para executar o script no arquivo. Em computadores UNIX e Mac,
execute o comando abaixo no terminal:
gradle -q run

If you haven't onboarded yet, follow the steps in *Get started* in the [Reseller portal guide](/zero-touch/guides/portal).\n- Java 1.7 or greater.\n- [Gradle 2.3 or greater](http://gradle.org/downloads).\n- Access to the internet and a web browser.\n\nStep 1: Turn on the zero-touch enrollment API\n---------------------------------------------\n\n1. Use [this\n wizard](https://console.developers.google.com/start/api?id=androiddeviceprovisioning.googleapis.com) to create or select a project in the Google Developers Console and automatically turn on the API. Click **Continue** , then **Go to credentials**.\n2. Set **What data will you be accessing?** to *Application data*.\n3. Click **Next**. You should be prompted to create a service account.\n4. Give a descriptive name for **Service account name**.\n5. Note the **Service account ID** (it looks like an email address) because you'll use it later.\n6. Set **Role** to *Service Accounts \\\u003e Service Account User*.\n7. Click **Done** to finish creating the service account.\n8. Click the email address for the service account that you created.\n9. Click \\*\\*Keys\\*\\*.\n10. Click \\*\\*Add key\\*\\*, then click \\*\\*Create new key\\*\\*.\n11. For \\*\\*Key type\\*\\*, select \\*\\*JSON\\*\\*.\n12. Click **Create** and the private key downloads to your computer.\n13. Click \\*\\*Close\\*\\*.\n14. Move the file to your working directory and rename it `service_account_key.json`.\n\n| **Warning:** Service account keys can become a security risk if not managed carefully. For advice see [best practices for managing API keys](https://cloud.google.com/iam/docs/best-practices-for-managing-service-account-keys).\n\nStep 2: Link the service account\n--------------------------------\n\n1. Open the zero-touch enrollment [portal](https://enterprise.google.com/android/zero-touch/resellers). You might need to sign in.\n2. Click settings_ethernet **Service\n accounts**.\n3. Click add **Link service account**.\n4. Set **Email address** to the address of the service account you created.\n5. Click **Link service account** to use the service account with your zero-touch enrollment account.\n\nStep 3: Prepare the project\n---------------------------\n\nFollow the steps below to set up your Gradle project:\n\n1. Run the following command to create a new project in the working directory:\n\n gradle init --type basic\n mkdir -p src/main/java src/main/resources\n\n2. Copy the `service_account_key.json` file you downloaded in Step 1 into the\n `src/main/resources/` directory you created above.\n\n3. Open the default `build.gradle` file and replace its contents with the\n following code:\n\n apply plugin: 'java'\n apply plugin: 'application'\n\n mainClassName = 'ResellerQuickstart'\n sourceCompatibility = 1.7\n targetCompatibility = 1.7\n version = '1.0'\n\n repositories {\n mavenCentral()\n }\n\n dependencies {\n compile 'com.google.api-client:google-api-client:1.30.11'\n compile 'com.google.apis:google-api-services-androiddeviceprovisioning:+'\n compile 'com.google.oauth-client:google-oauth-client-jetty:+'\n }\n\nStep 4: Set up the sample\n-------------------------\n\nCreate a file named `src/main/java/ResellerQuickstart.java` and copy in the\nfollowing code and save the file.

To find your\npartner ID from the zero-touch enrollment portal, follow the steps below:\n\n1. Open the [portal](https://enterprise.google.com/android/zero-touch/resellers). You might need to sign in.\n2. Click settings_ethernet **Service\n accounts**.\n3. Copy your partner ID number from the **Your reseller ID** line.\n\nStep 5: Run the sample\n----------------------\n\nUse your operating system's help to run the script in the file. On UNIX and Mac\ncomputers, run the command below in your terminal: \n\n gradle -q run\n\nTroubleshooting\n---------------\n\n\n[Tell us what went wrong]() with the quickstart and we'll work to\nfix it.
