Azure Python Function V2 编程模型即使在 Azure 中部署后也未显示功能

问题描述 投票：0回答：1

我想在 Python 中使用 Azure Function 部署 CRON 计时器触发器。我尝试使用 VS Code 部署它。

以下是我遵循的步骤：

第 1 步： 安装以下所有先决条件：

  1. 已安装 Azure Core Tools v4
  2. 已安装 Azurite V3 扩展。
  3. 使用 Python 3.11.8。
  4. Windows 中最新版本的 VS Code
  5. 已安装 Azure 功能扩展

第 2 步： 使用消费计划创建 Azure Python 函数

第 3 步： 使用 Python v2 模型创建函数应用程序

Used VS Code Azure Extension to create Function locally

步骤 4： 在默认函数代码中进行所需的更改后，我尝试通过选择所需的函数应用程序使用 VS Code Azure 扩展来部署该代码： Deployed using following Azure Extension

第 5 步： 检查部署状态。在VS Code中显示成功。在门户中，所有未被忽略的文件都会上传到 Azure 函数资源，但不会显示为函数。

Function is not showing up in overview

However I can see files successfully deployed in App File Section

第6步：我还检查了VS Code中部署的Azure Function，但在Function下看不到function.json。

Cross checked in VS Code

我的 function_app.py 如下所示：

  • 确保您已在 
    local.settings.json
    中添加了所有必需的应用程序设置。
  • 添加存储连接字符串作为 
    "AzureWebJobsStorage"
    设置的值。
"AzureWebJobsFeatureFlags": "EnableWorkerIndexing"

local.settings.json：

{
  "IsEncrypted": false,
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsFeatureFlags": "EnableWorkerIndexing",
    "AzureWebJobsStorage": "<Storage_connection_string>"
  }
}
  • 确保您已在 Azure Function App 中添加所有环境变量。

主机.json：

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}

  • 将所有必需的包包含在requirements.txt中。

  • 创建一个新的虚拟环境并使用以下命令激活：

py -m venv env
.\env\Scripts\activate

使用以下命令安装软件包：

pip install -r requirements.txt
  • 在本地运行该函数。

使用以下命令再次将函数部署到Azure Function App（消费计划）：

func azure functionapp publish <functionapp_name>
