Segui i passaggi descritti in questa guida rapida e in circa 10 minuti avrai una semplice app da riga di comando Python che invia richieste all'API cliente per la registrazione zero-touch.
Prerequisiti
Per eseguire questa guida rapida, devi disporre di:
- Un Account Google che fa parte del tuo account cliente con registrazione zero-touch. Consulta la Guida introduttiva.
- Python 3.0 o versioni successive.
- Lo strumento di gestione dei pacchetti pip.
- Accesso a internet e a un browser web.
Passaggio 1: attiva l'API per la registrazione zero-touch
- Utilizza 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
.
- Fai clic su Annulla in Crea credenziali.
- Nella parte superiore della pagina, seleziona la scheda Schermata consenso OAuth. Seleziona un
indirizzo email, inserisci un nome prodotto, se non è già impostato, e
fai clic sul pulsante Salva.
- Seleziona la scheda Credenziali, fai clic sul pulsante Crea credenziali
e seleziona ID client OAuth.
- Seleziona il tipo di applicazione Other, inserisci il nome "Quickstart" e fai clic sul pulsante Crea.
- Fai clic su OK per chiudere il riquadro Client OAuth.
- Fai clic su file_download Scarica JSON.
- Sposta il file nella directory di lavoro e rinominalo
client_secret.json
.
Passaggio 2: installa la libreria client di Google
Esegui il seguente comando per installare la libreria utilizzando pip:
pip install --upgrade google-api-python-client oauth2client
Consulta la pagina di installazione della libreria per le varie opzioni di installazione.
Passaggio 3: configura il sample
Crea un file denominato quickstart.py
nella directory di lavoro. Copia il
seguente codice e salva il file.
#!/usr/bin/env python
# -*- coding: utf-8 -*-

dpcName = dpc['dpcName']
else:
dpcName = "-"
print('Name:{0} APK:{1}'.format(dpcName, dpc['packageName']))
if __name__ == '__main__':
main()
Passaggio 4: 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:
python quickstart.py
La prima volta che esegui l'app, devi autorizzare l'accesso:
- L'app tenta di aprire una nuova scheda nel browser predefinito. Se l'operazione non va a buon fine, copia l'URL dalla console e apri la pagina nel browser. Se non hai ancora eseguito l'accesso al tuo Account Google, ti viene richiesto di farlo. Se hai eseguito l'accesso a più Account Google, la pagina ti chiede di selezionare
un account per l'autorizzazione.
- Fai clic su Accept (accetta).
- Chiudi la scheda del browser: l'app continua a funzionare.
Note
- Poiché la libreria client dell'API di Google memorizza i dati di autorizzazione nel file system, i lanci successivi non richiedono l'autorizzazione.
- Per reimpostare i dati di autorizzazione dell'app, elimina il
file
user_credential.json
ed esegui di nuovo l'app.
- Il flusso di autorizzazione in questa guida rapida è ideale per un'app a riga di comando. Per scoprire come aggiungere l'autorizzazione a un'app web, consulta l'articolo Utilizzare OAuth 2.0 per le applicazioni server web.
Risoluzione dei problemi
Di seguito sono riportati alcuni aspetti comuni da controllare.
Indicaci il problema con la guida rapida e ci occuperemo di risolverlo.
- Verifica di autorizzare le chiamate API con lo stesso Account Google che fa parte del tuo account cliente per la registrazione zero-touch. Prova ad accedere al portale della registrazione zero-touch utilizzando lo stesso Account Google per testare l'accesso.
- Verifica che l'account abbia accettato i Termini di servizio più recenti nel
portale. Vedi
Account cliente.

See [Get\n started](/zero-touch/guides/customer/how-it-works#get_started).\n- Python 3.0 or greater.\n- The [pip](https://pypi.python.org/pypi/pip) package management tool.\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. Click **Cancel** on the Create credentials.\n3. At the top of the page, select the **OAuth consent screen** tab. Select an **Email address** , enter a **Product name** if not already set, and click the **Save** button.\n4.

Select the application type **Other** , enter the name \"Quickstart\", and click the **Create** button.\n6. Click **OK** to dismiss the *OAuth client* panel.\n7. Click file_download **Download JSON**.\n8. Move the file to your working directory and rename it `client_secret.json`.\n\nStep 2: Install the Google client library\n-----------------------------------------\n\nRun the following command to install the library using pip: \n\n pip install --upgrade google-api-python-client oauth2client\n\nSee the library's [installation\npage](/api-client-library/python/start/installation) for different installation\noptions.\n\nStep 3: Set up the sample\n-------------------------\n\nCreate a file named `quickstart.py` in your working directory.

On UNIX and Mac\ncomputers, run the command below in your terminal: \n\n python quickstart.py\n\nThe first time you run the app, you need to authorize access:\n\n1. The app tries to open a new tab in your default browser. If this fails, copy the URL from the console and open it in your browser. If you're not already logged into your Google Account, you're prompted to log in. If you're logged into multiple Google accounts, the page prompts you to select an account for the authorization.\n2. Click **Accept**.\n3. Close the browser tab---the app continues running.\n\nNotes\n-----\n\n- Because Google API client library stores authorization data on the file system, subsequent launches don't prompt you for authorization.\n- To reset the app's authorization data, delete the `user_credential.json` file and run the app again.\n- The authorization flow in this quickstart is ideal for a command-line app. To learn how to add authorization to a web app, see [Using OAuth 2.0 for Web Server Applications](/api-client-library/python/auth/web-app).\n\nTroubleshooting\n---------------\n\nHere are some common things you'll want to check.\n[Tell us what went wrong]() with the quickstart and we'll work to fix it.\n\n- Check that you're authorizing API calls with the same Google Account that's a member of your zero-touch enrollment customer account. Try signing in to the zero-touch enrollment [portal](https://enterprise.google.com/android/zero-touch/resellers) using the same Google Account to test your access.\n- Confirm that the account has accepted the latest Terms of Service in the [portal](https://enterprise.google.com/android/zero-touch/resellers). See [Customer accounts](/zero-touch/guides/customer/auth#customer_accounts).\n\nLearn more\n----------\n\n- [Google Developers Console help documentation](/console/help/new)\n- [Google APIs Client for Python documentation](/api-client-library/python)\n- [pip User Guide](https://pip.pypa.io/en/stable/user_guide/)"]]
