Segui i passaggi descritti in questa guida rapida e in circa 10 minuti avrai una semplice app a riga di comando Java che invia richieste all'API per i rivenditori di registrazione zero-touch.
Prerequisiti
Per eseguire questa guida rapida, ti serviranno:
Passaggio 1: attiva l'API di registrazione zero-touch
- Usa questa procedura guidata per creare o selezionare un progetto in Google Developers Console e attivare automaticamente l'API. Fai clic su Continua, quindi su Vai alle credenziali
.
- Imposta A quali dati accederai? su Dati dell'applicazione.
- Fai clic su Avanti. Viene richiesto di creare un account di servizio.
- Assegna un nome descrittivo a Nome account di servizio.
- Prendi nota dell'ID account di servizio (assomiglia a un indirizzo email) perché lo utilizzerai in seguito.
- Imposta Ruolo su Account di servizio > Utente account di servizio.
- Fai clic su Fine per completare la creazione dell'account di servizio.
- Fai clic sull'indirizzo email dell'account di servizio che hai creato.
- Fai clic su **Chiavi**.
- Fai clic su **Aggiungi chiave**, quindi su **Crea nuova chiave**.
- In **Tipo di chiave**, seleziona **JSON**.
- Fai clic su Crea e la chiave privata viene scaricata sul computer.
- Fai clic su **Chiudi**.
- Sposta il file nella directory di lavoro e rinominalo
service_account_key.json.
Passaggio 2: collega l'account di servizio
- Apri il portale per la registrazione zero-touch. Potresti dover eseguire l'accesso.
- Fai clic su settings_ethernet Account di servizio.
- Fai clic su add Collega account di servizio.
- Imposta Indirizzo email sull'indirizzo dell'account di servizio che hai creato.
- Fai clic su Collega account di servizio per utilizzare l'account di servizio con il tuo account di registrazione zero-touch.
Passaggio 3: prepara il progetto
Per configurare il progetto Gradle:
Esegui il comando seguente per creare un nuovo progetto nella directory di lavoro:
gradle init --type basic
mkdir -p src/main/java src/main/resources
Copia il file service_account_key.json scaricato nel passaggio 1 nella directory src/main/resources/ creata sopra.
Apri il file build.gradle predefinito e sostituiscine il contenuto con il seguente codice:
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:+'
}
Passaggio 4: configura il sample
Crea un file denominato src/main/java/ResellerQuickstart.java, copia il codice seguente e salva il file. Inserisci il tuo ID partner rivenditori come valore per PARTNER_ID (la prima riga dell'app).
import com.google.api.client.auth.oauth2.Credential;

}
ID partner
In genere, le chiamate API richiedono l'ID partner rivenditore come argomento. Per trovare il tuo
ID partner dal portale della registrazione zero-touch, segui questi passaggi:
- Apri il portale. Potresti dover eseguire l'accesso.
- Fai clic su settings_ethernet Account di servizio.
- Copia il numero dell'ID partner dalla riga Il tuo ID rivenditore.
Passaggio 5: esegui il sample
Utilizza la guida del sistema operativo per eseguire lo script nel file. Sui computer UNIX e Mac, esegui il comando seguente nel terminale:
gradle -q run
Risoluzione dei problemi
Spiegaci il problema con la guida rapida e ci occuperemo di risolverlo. Per scoprire in che modo la funzionalità zero-touch utilizza gli account di servizio per autorizzare le chiamate API, consulta

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.
