Azure Functions - BlobTrigger - How to trigger function with any file in a container?

问题

I'm facing a problem with an Azure Function.

我正在遇到Azure函数的问题。

I've build an Azure Function triggered by a new file on a container of a storage account.
The problem is that it seems impossible (to me) to trigger the function with a generic file, without specifing a name!

我已经创建了一个由存储账户容器中的新文件触发的Azure函数。
问题是,似乎不可能(对我来说)触发一个没有指定名称的通用文件的函数!

I've searched on official documentation and it's not specified how to reference a generic file. The expected behaviour is to have a function triggered when I upload any file (with any name) in a specific container, something like "container/*".

我已经在官方文档中搜索过,但没有指定如何引用通用文件。期望的行为是在特定容器中上传任何文件(具有任何名称)时触发函数,类似于"container/*"。

This is my simple function:

这是我的简单函数:

function.json

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "name": "inputBlob",
      "type": "blobTrigger",
      "direction": "in",
      "path": "premium-input/*",
      "connection": "AzureWebJobsStorage"
    }
  ]
}

init.py

import logging
import azure.functions as func

def main(inputBlob: func.InputStream):
    logging.info("START EXECUTION")
    logging.info(f'NAME {inputBlob.name}')
    logging.info(f'URI {inputBlob.uri}')
    logging.info("END EXECUTION")

I've already tried using an event on EventGrid, but I prefer avoiding it...

我已经尝试过在EventGrid上使用事件,但我更倾向于避免它...

Can you please help me?

你能帮助我吗?

Thanks in advance!!

提前感谢您!

我尝试将通用文件上传到容器中,如下所示,我的函数已被触发。如果您将路径 premium-input/* 更改为 premium-input/{name},它将起作用。

init.py

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"URI: {myblob.uri}\n"
                 f"Blob Size: {myblob.length} bytes")

function.json

{
    "bindings": [
        {
            "name": "myblob",
            "type": "blobTrigger",
            "direction": "in",
            "path": "demo/{name}",
            "connection": "your connection string"
        }
    ]
}

英文:

I have tried to upload generic files to a container as below and my function got triggered. If you will change the path premium-input/* to premium-input/{name} , it will work.

init.py

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"URI: {myblob.uri}\n"
f"Blob Size: {myblob.length} bytes")

function.json

{
"bindings": [
{
"name": "myblob",
"type": "blobTrigger",
"direction": "in",
"path": "demo/{name}",
"connection": "your connection string"
}
]
}
