빠른 시작에서는 Google Workspace API를 호출하는 앱을 설정하고 실행하는 방법을 설명합니다. 이 빠른 시작에서는 테스트 환경에 적합한 간소화된 인증 방식을 사용합니다. 프로덕션 환경의 경우 앱에 적합한 액세스 사용자 인증 정보 선택 전에 인증 및 승인에 대해 알아보는 것이 좋습니다.
Drive Labels API에 요청을 보내는 Python 명령줄 애플리케이션을 만듭니다.
최종 사용자를 인증하고 앱에서 사용자 데이터에 액세스하려면 OAuth 2.0 클라이언트 ID를 하나 이상 만들어야 합니다. 클라이언트 ID는 Google OAuth 서버에서 단일 앱을 식별하는 데 사용됩니다. 앱이 여러 플랫폼에서 실행되는 경우 플랫폼별로 별도의 클라이언트 ID를 만들어야 합니다.

샘플 실행
작업 디렉터리에서 샘플을 빌드하고 실행합니다.
pythonquickstart.py
샘플을 처음 실행하면 액세스 권한을 승인하라는 메시지가 표시됩니다.
아직 Google 계정에 로그인하지 않았다면 로그인하라는 메시지가 표시됩니다. 여러 계정에 로그인되어 있는 경우 승인에 사용할 계정을 하나 선택합니다.
수락을 클릭합니다.
승인 정보는 파일 시스템에 저장되므로 다음에 샘플 코드를 실행할 때는 승인 메시지가 표시되지 않습니다.
Drive Labels API에 요청을 보내는 첫 번째 Python 애플리케이션을 성공적으로 만들었습니다.

This quickstart uses a\nsimplified authentication approach that is appropriate for a testing\nenvironment. For a production environment, we recommend learning about\n[authentication and authorization](/workspace/guides/auth-overview)\nbefore\n[choosing the access credentials](/workspace/guides/create-credentials#choose_the_access_credential_that_is_right_for_you)\nthat are appropriate for your app.\n\nCreate a Python command-line application that makes requests to the\nDrive Labels API.\n\nObjectives\n\n- Set up your environment.\n- Install the client library.\n- Set up the sample.\n- Run the sample.\n\nPrerequisites\n\n- Python 2.6 or greater\n- The [pip](https://pypi.python.org/pypi/pip) package management tool\n- [A Google Cloud project](/workspace/guides/create-project).\n\n\u003c!-- --\u003e\n\n- A Google Account.\n\nSet up your environment\n\nTo complete this quickstart, set up your environment.\n\nEnable the API Before using Google APIs, you need to turn them on in a Google Cloud project. You can turn on one or more APIs in a single Google Cloud project.\n\n- In the Google Cloud console, enable the Drive Labels API.\n\n [Enable the API](https://console.cloud.google.com/flows/enableapi?apiid=drivelabels.googleapis.com)\n\nAuthorize credentials for a desktop application To authenticate end users and access user data in your app, you need to create one or more OAuth 2.0 Client IDs. A client ID is used to identify a single app to Google's OAuth servers. If your app runs on multiple platforms, you must create a separate client ID for each platform.\n\n1. In the Google Cloud console, go to Menu menu \\\u003e **Google Auth platform** \\\u003e **Clients** .\n\n [Go to Clients](https://console.cloud.google.com/auth/clients)\n2. Click **Create Client**.\n3. Click **Application type** \\\u003e **Desktop app**.\n4. In the **Name** field, type a name for the credential. This name is only shown in the Google Cloud console.\n5. Click **Create** .\n\n\n The newly created credential appears under \"OAuth 2.0 Client IDs.\"\n6. Save the downloaded JSON file as `credentials.json`, and move the file to your working directory.\n\nInstall the Google client library\n\n- Install the Google client library for Python:\n\n pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib\n\nFor alternate installation options, refer to the Python library's\n[Installation section](/api-client-library/python/start/installation#installation).\n\nConfigure the sample\n\n1. In your working directory, create a file named `quickstart.py`.\n2. Include the following code in `quickstart.py`:\n\n import os.path\n\n from google.auth.transport.requests import Request\n from google.oauth2.credentials import Credentials\n from google_auth_oauthlib.flow import InstalledAppFlow\n from googleapiclient.discovery import build\n from googleapiclient.errors import HttpError\n\n # If modifying these scopes, delete the file token.json.\n SCOPES = ['https://www.googleapis.com/auth/drive.labels.readonly']\n\n def main():\n \"\"\"Shows basic usage of the Drive Labels API.\n\n Prints the first page of the customer's Labels.\n \"\"\"\n creds = None\n # The file token.json stores the user's access and refresh tokens, and is\n # created automatically when the authorization flow completes for the first\n # time.\n if os.path.exists('token.json'):\n creds = Credentials.from_authorized_user_file('token.json', SCOPES)\n # If there are no (valid) credentials available, let the user log in.\n if not creds or not creds.valid:\n if creds and creds.expired and creds.refresh_token:\n creds.refresh(Request())\n else:\n flow = InstalledAppFlow.from_client_secrets_file('credentials.json',\n SCOPES)\n creds = flow.run_local_server(port=0)\n # Save the credentials for the next run\n with open('token.json', 'w') as token:\n token.write(creds.to_json())\n try:\n service = build('drivelabels', 'v2', credentials=creds)\n response = service.labels().list(\n view='LABEL_VIEW_FULL').execute()\n labels = response['labels']\n\n if not labels:\n print('No Labels')\n else:\n for label in labels:\n name = label['name']\n title = label['properties']['title']\n print(u'{0}:\\t{1}'.format(name, title))\n except HttpError as error:\n # TODO (developer) - Handle errors from Labels API.\n print(f'An error occurred: {error}')\n\n if __name__ == '__main__':\n main()\n\nRun the sample\n\n1. In your working directory, build and run the sample:\n\n python quickstart.py\n\n2. The first time you run the sample, it prompts you to authorize access:\n\n 1. If you're not already signed in to your Google Account, you're prompted to sign in. If you're signed in to multiple accounts, select one account to use for authorization.\n 2. Click **Accept**.\n\n Authorization information is stored in the file system, so the next time you\n run the sample code, you aren't prompted for authorization.\n\nYou have successfully created your first Python application that makes requests to\nthe Drive Labels API.\n\nNext steps\n\n- [Troubleshoot authentication and authorization issues](/workspace/drive/labels/troubleshoot-authentication-authorization)\n- [Google APIs Client for Python documentation](/api-client-library/python)"]]
