在本地运行 Azure 函数会导致工作错误

Question

我使用 Azure 文档中的以下 CLI 命令在 Windows 上创建了本地 Azure 函数项目：

func init --python
 
func new --name HttpExample --template "HTTP trigger" --authlevel "anonymous"

使用

func start

命令启动该函数后，工作程序退出并出现以下错误：

Found Python version 3.12.0 (py).

我该如何解决这个问题？

我尝试过的：

• 我检查了核心 Azure Functions 核心工具是否正常工作
• 我更新了 pip 并重新创建了 python venv
• 我重新安装了Azure Function Core Tools
• 我检查了 npm 和 node.js 是否已正确安装并正常运行
• 我在不同的目录中重新执行了文档中的所有步骤，以确保我没有遗漏任何内容

由于 func new 命令中提供的

无效的 authlevel

，您收到错误。

您应该将命令中的anonymous更改为ANONYMOUS。

更改命令如下：

func new --name HttpExample --template "HTTP trigger" --authlevel "ANONYMOUS"

或者您可以更改功能代码中的以下行

auth_level=func.AuthLevel.anonymous

到

auth_level=func.AuthLevel.ANONYMOUS

function_app.py：

import azure.functions as func
import datetime
import json
import logging

app = func.FunctionApp()

@app.route(route="HttpExample", auth_level=func.AuthLevel.ANONYMOUS)
def HttpExample(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:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    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.",
             status_code=200
        )

输出：

C:\Users\uname\pyfunc> func start
