客戶的 Python 快速入門導覽課程
透過集合功能整理內容
你可以依據偏好儲存及分類內容。
只要按照本快速入門指南的步驟操作,大約 10 分鐘內,您就能完成一個簡單的 Python 指令列應用程式,向零接觸註冊客戶 API 提出要求。
必要條件
如要執行這個快速入門,您需要:
- Google 帳戶,也就是零接觸註冊機制客戶帳戶的成員。請參閱開始使用。
- Python 3.0 以上版本。
- pip 套件管理工具。
- 可連上網際網路並具備網路瀏覽器。
步驟 1:啟用零接觸註冊 API
- 使用這個精靈,在 Google Developers Console 中建立或選取專案,並自動開啟 API。按一下「繼續」,然後點選「前往憑證」。
- 按一下「建立憑證」中的「取消」。
- 選取頁面頂端的「OAuth 同意畫面」分頁標籤。選取電子郵件地址,如果尚未設定產品名稱,請輸入產品名稱,然後按一下「儲存」按鈕。
- 選取「Credentials」(憑證) 分頁標籤,按一下「Create credentials」(建立憑證) 按鈕,然後選取「OAuth client ID」(OAuth 用戶端 ID)。
- 選取「Other」應用程式類型,並輸入「quickstart」這個名稱,然後按一下 [Create] 按鈕。
- 按一下「OK」,關閉「OAuth 用戶端」面板。
- 按一下「下載 JSON」file_download。
- 將檔案移至工作目錄,並重新命名為
client_secret.json
。
步驟 2:安裝 Google 用戶端程式庫
執行下列指令,使用 pip 安裝程式庫:
pip install --upgrade google-api-python-client oauth2client
如要瞭解其他安裝選項,請參閱程式庫的安裝頁面。
步驟 3:設定範例
在工作目錄中建立名為 quickstart.py
的檔案。複製下列程式碼並儲存檔案。
#!/usr/bin/env python

# that authorizes the request can access the zero-touch portal.
print('No zero-touch enrollment account found.')
sys.exit()

# account.

if 'dpcName' in dpc:
dpcName = dpc['dpcName']
else:
dpcName = "-"
print('Name:{0} APK:{1}'.format(dpcName, dpc['packageName']))
if __name__ == '__main__':
main()
步驟 4:執行範例
請使用作業系統的說明,執行檔案中的指令碼。在 UNIX 和 Mac 電腦上,在終端機中執行下列指令:
python quickstart.py
第一次執行應用程式時,您必須授予存取權:
- 應用程式會嘗試在預設瀏覽器中開啟新分頁。如果失敗,請從控制台中複製網址,然後在瀏覽器中開啟網址。如果您尚未登入 Google 帳戶,系統會提示您登入。如果您登入了多個 Google 帳戶,系統會在該頁面提示您選取要授權的帳戶。
- 然後點選 [Accept]。
- 關閉瀏覽器分頁,應用程式會繼續執行。
附註
- Google API 用戶端程式庫會在檔案系統中儲存授權資料,因此後續啟動不會提示您進行授權。
- 如要重設應用程式的授權資料,請刪除
user_credential.json
檔案,然後再次執行應用程式。
- 本快速入門課程中的授權流程非常適合指令列應用程式。如要瞭解如何為網路應用程式新增授權,請參閱「針對網路伺服器應用程式使用 OAuth 2.0」。
疑難排解
以下是一些常見的檢查項目。請告訴我們快速入門導覽課程有哪些錯誤,我們會盡力修正。
- 請確認您是使用零接觸註冊機制客戶帳戶的會員帳戶,授權 API 呼叫。請嘗試使用相同的 Google 帳戶登入零接觸註冊機制入口網站,測試您的存取權。
- 確認帳戶已在入口網站接受最新的《服務條款》。請參閱「客戶帳戶」。

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 **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-----------------------------------------\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. 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\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/)"]]
