do cliente sem contato.
Pré-requisitos
Para executar este guia de início rápido, você precisa de:
- Uma Conta do Google que é membro da sua conta de registro sem toque para clientes. Consulte o artigo Começar.
- Python 3.0 ou mais recente.
- A ferramenta de gerenciamento de pacotes
pip.
- 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
.
- Clique em Cancelar em "Criar credenciais".
- Na parte superior da página, selecione a guia OAuth consent screen. Selecione um
endereço de e-mail, insira um nome do produto, se ainda não tiver sido definido, e
clique no botão Salvar.
- Selecione a guia Credentials, clique no botão Create credentials e selecione OAuth client ID.
- Selecione o tipo de aplicativo Outro, insira o nome "Guia de início rápido" e clique no botão Criar.
- Clique em OK para fechar o painel Cliente OAuth.
- Clique em file_download Fazer o download do JSON.
- Mova o arquivo para o diretório de trabalho e renomeie-o como
client_secret.json
.
Etapa 2: instalar a biblioteca de cliente do Google
Execute o comando a seguir para instalar a biblioteca usando o pip:
pip install --upgrade google-api-python-client oauth2client
Consulte a página de instalação da biblioteca para conferir as diferentes opções
de instalação.
Etapa 3: configurar o exemplo
Crie um arquivo chamado quickstart.py
no diretório de trabalho. Copie o código a seguir e salve o arquivo.
#!/usr/bin/env python

main()
Etapa 4: executar a amostra
Use a ajuda do sistema operacional para executar o script no arquivo. Em computadores UNIX e Mac, execute o comando abaixo no seu terminal:
python quickstart.py
Na primeira vez que você executar o app, será necessário autorizar o acesso:
- O app tenta abrir uma nova guia no navegador padrão. Se isso não funcionar, copie o URL do console e abra-o no navegador. Se você ainda não estiver conectado à sua Conta do Google, será solicitado que você faça login. Se você estiver conectado a várias Contas do Google, a página solicitará que você selecione uma conta para a autorização.
- Clique em Aceitar.
- Feche a guia do navegador. O app continua em execução.
Observações
- Como a biblioteca de cliente da API do Google armazena dados de autorização no sistema de arquivos, as inicializações
subsequentes não solicitam autorização.
- Para redefinir os dados de autorização do app, exclua o
arquivo
user_credential.json
e execute o app novamente.
- O fluxo de autorização neste guia de início rápido é ideal para um app de linha de comando. Para saber como adicionar
autorização a um app da Web, consulte
Como usar o OAuth 2.0 para aplicativos de servidor da Web.
Solução de problemas
Aqui estão alguns itens comuns que você precisará verificar.
Informe o que deu errado com o guia de início rápido, e vamos trabalhar para corrigir o problema.
- Verifique se você está autorizando chamadas de API com a mesma Conta do Google que é membro da sua conta de cliente de registro sem toque. Tente fazer login no portal de registro sem toque usando a
mesma Conta do Google para testar seu acesso.
- Confirme se a conta aceitou os Termos de Serviço mais recentes no
portal. Consulte
Contas de 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\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 **Credentials** tab, click the **Create credentials** button and select **OAuth client ID**.\n5. 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\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\nCreate a file named `quickstart.py` in your working directory. Copy in the\nfollowing code and save the file. \n\n```python\n#!/usr/bin/env python\n# -*- coding: utf-8 -*-\n\"\"\"Zero-touch enrollment quickstart sample.\n\nThis script forms the quickstart introduction to the zero-touch enrollemnt\ncustomer API.

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- 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\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- [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/)"]]
