Azure Function 应用程序 HTTP 触发函数在部署时不显示

Question

我用的是Python 3.9（Python编程model v2），我根据官方的例子创建了一个HTTP Function。 当我使用 visual studio code 进行部署时，我收到这条 output 消息，但我不知道如何调用 function。在我的本地调试环境中一切正常。 当我部署时，应用程序创建成功，文件被复制并安装了所有要求，但这些功能没有显示在 visual studio 的资源选项卡或 web 门户中。

仅供参考 - 在部署 output 中，我将我的实际应用名称更改为“appname”。

这是我尝试开始工作的默认值 function：

    @app.route(route="hello", auth_level=func.AuthLevel.ANONYMOUS)
    def test_function(req: func.HttpRequest) -> func.HttpResponse:
         logging.info('Python HTTP trigger function processed a request.')

     name = req.params.get('name')
     if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

     if name:

     else:
        return func.HttpResponse(
             "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",

Answer 1

我创建了 Azure 函数 Python 编程 model v2 并且在本地运行时出现了一些错误，即：

然后我在本地启动了 Azure 存储模拟器，错误已修复。

在本地运行：

部署到 Azure ：

Note : After deploying to Azure, update the app settings which is newly added in local.settings.json for Python V2 model to the Azure by pressing F1 on VS Code > Add New Setting on Azure Functions > Add this key value pair - AzureWebJobsFeatureFlags : EnableWorkerIndexing 。

有关使用 Azure 和 Python V2 model 运行功能的更多信息，请参阅此MS 文档。

Answer 2

Hari 的解决方案效果很好。 但是，这可能有点令人困惑。 Azure 函数的 VSCode 教程中描述了该问题的精确解决方案。

简而言之，您想将以下设置添加到您的 Azure Function 应用程序设置中：

AzureWebJobsFeatureFlags: EnableWorkerIndexing

它与您可能还添加到本地环境中的条目相同。 Azure也需要设置。 最起码到现在。
