我如何使用 os.environ select 環境變量（使用 VSCode 和 Python）

Question

我正在 VSCode 中構建一個 Azure Function 並且無法在本地獲取我的 function 以引用我添加到 local.settings.json 的環境變量，因為我在嘗試訪問我的環境變量時遇到錯誤。 我想訪問名為 clientId 的那個。

我的 local.settings.json：

    {
      "IsEncrypted": false,
      "Values": {
      "AzureWebJobsStorage": "",
      "FUNCTIONS_WORKER_RUNTIME": "python",
      "clientId": "test123"
      }
    }

我的腳本：

import os
import azure.functions as func

print(os.environ['clientId'])

錯誤：

  File "c:\Users\xxxx\source\Repos\xxxx\Python\xxxx\HttpTrigger1\__init__.py", line 7, in <module>
    print(os.environ['clientID'])
  File "C:\Program Files\WindowsApps\PythonSoftwareFoundation.Python.3.9_3.9.3312.0_x64__qbz5n2kfra8p0\lib\os.py", 
line 679, in __getitem__
    raise KeyError(key) from None
KeyError: 'clientID'

為了嘗試解決此問題，我嘗試打印所有期望看到我的 local.settings.json 的環境變量，但是我沒有看到任何類似於 local.settings.json 文件的內容。

腳本：

import os
import azure.functions as func

print(os.environ)

回復：

local.settings.json是Azure函數使用的配置文件。 它不是鏈接到 Python 本身的東西，可以直接在任何環境中工作。

使用這個模塊，如果你用它啟動 Azure Function，它應該在本地模擬 AzureDevOps 上下文。
