Azure 函数应用 （Python v2） - 部署后未显示blob_trigger函数

问：

我有一个 Python v2 编程模型中的函数应用，它有一个blob_trigger，它应该对在给定存储帐户和容器中创建的新 blob 执行 sth。我在 VSCode 工作。使用 Azurite 在本地运行时，函数应用运行良好，但是当我将其部署到 Azure 时，函数应用下没有“blobTrigger”函数。

这是我的代码：function_app.py

import azure.functions as func
from azure.storage.blob.aio import BlobServiceClient

import datetime
import logging
import json
import os
import sys
import asyncio

_KV_SECRET_INPUT_BLOB_CONNECTION_STRING = os.environ["KV_SECRET_INPUT_BLOB_CONNECTION_STRING"]
STORAGE_CONTAINER_NAME = os.environ["STORAGE_CONTAINER_NAME"]

async def read_blob_contents(connection_string: str, input_container_name: str, input_blob_name: str):
    blob_service_client = BlobServiceClient.from_connection_string(connection_string)
    container_client = blob_service_client.get_container_client(input_container_name)
    blob_client = container_client.get_blob_client(input_blob_name)

    try:
        blob_contents = await blob_client.download_blob(encoding = 'utf-8')
        return await blob_contents.readall()
    except Exception as e:
        logging.error(f"Error reading blob: {str(e)}")
        return None
    finally:
        await blob_service_client.close()


app = func.FunctionApp()
@app.function_name(name="blobTrigger")
@app.blob_trigger(arg_name="myblob", path=STORAGE_CONTAINER_NAME, connection="KV_SECRET_INPUT_BLOB_CONNECTION_STRING")

async def blob_trigger(myblob: func.InputStream, context: func.Context) -> None:

    func_invoc_and_event_meta = json.dumps({
        "function_name" : context.function_name,
        "function_invocation_id" : context.invocation_id,
        'blob_name': myblob.name,
        'blob_length': myblob.length,
        'blob_uri': myblob.uri,
    }, indent=4)

    logging.info('Blob trigger processed an event:')
    logging.info(func_invoc_and_event_meta)

    logging.info("Attempting to read the blob...")
    
    try:
        blob_url = myblob.uri
        logging.info(f"blob_url: '{blob_url}'")
               
        # Read the contents of the blob asynchronously
        input_container_name = myblob.name.split('/', maxsplit=1)[0]
        input_blob_name = myblob.name.split('/', maxsplit=1)[1]
        blob_contents = await read_blob_contents(connection_string=_KV_SECRET_INPUT_BLOB_CONNECTION_STRING, input_container_name=input_container_name, input_blob_name=input_blob_name)
        logging.error("blob reading completed")

    except:
        logging.error("ERROR during blob read : ")
        logging.error(str(sys.exc_info()))

我确保函数应用具有适当的应用设置，即 和。该设置包含旨在存储数据（新 Blob）的存储帐户的连接字符串，并且它与通过 appsetting 链接到函数应用的存储帐户不同。KV_SECRET_INPUT_BLOB_CONNECTION_STRINGSTORAGE_CONTAINER_NAMEKV_SECRET_INPUT_BLOB_CONNECTION_STRINGAzureWebJobsStorage

那么问题可能是什么呢？

与此相关的是，我还部署了另一个由 CRON 触发的函数应用程序，对于该应用程序，一切都按预期工作。
