Обновление ниже с более подробным выводом отладки
В прошлом я успешно запустил функции Azure с использованием локального узла разработки.
Я не смог получитьblobTrigger работает недавно.Я предпринял следующие шаги:
func init NewWave
cd NewWave
func new # -> select httpTrigger called HttpTrigger in language python
func new # -> select blobTrigger called BlobTrigger in language python
func host start
host.json содержит:
{
"version": "2.0",
"extensionBundle": {
"id": "Microsoft.Azure.Functions.ExtensionBundle",
"version": "[1.*, 2.0.0)"
}
}
local.settings.json содержит:
{
"IsEncrypted": false,
"Values": {
"FUNCTIONS_WORKER_RUNTIME": "python",
"AzureWebJobsStorage": "{AzureWebJobsStorage}"
}
}
AzureWebJobsStorage - это соединениестрока, заданная с помощью переменной среды.
BlobTrigger / function.json содержит:
{
"scriptFile": "__init__.py",
"bindings": [
{
"name": "myblob",
"type": "blobTrigger",
"direction": "in",
"path": "samples-workitems/{name}",
"connection": ""
}
]
}
__init__.py
содержит:
import logging
import azure.functions as func
def main(myblob: func.InputStream):
logging.info(f"Python blob trigger function processed blob \n"
f"Name: {myblob.name}\n"
f"Blob Size: {myblob.length} bytes")
HttpTrigger загружает, а BlobTrigger - нет.Вывод:
Azure Functions Core Tools (2.7.1373 Commit hash: cd9bfca26f9c7fe06ce245f5bf69bc6486a685dd)
Function Runtime Version: 2.0.12507.0
Warning: 'connection' property in '~/NewWave/BlobTrigger/function.json' is empty.
Skipping 'AzureWebJobsStorage' from local settings as it's already defined in current environment variables.

Что является причиной этой ошибки и как я могу ее устранить?
Если требуются какие-либо дополнительные настройки, журналы и т. Д., Пожалуйста, сообщите в комментариях ниже, и я будуобновление.
