Azure Functions Blob 部署

Question

我将在此处关闭文档：https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-output?tabs=python

这是我目前拥有的代码：

function.json


{
  "bindings": [
    {
      "queueName": "myqueue-items",
      "connection": "nameofstorageaccount_STORAGE",
      "name": "queuemsg",
      "type": "queueTrigger",
      "direction": "in"
    },
    {
      "name": "inputblob",
      "type": "blob",
      "dataType": "binary",
      "path": "samples-workitems/{queueTrigger}",
      "connection": "nameofstorageaccount_STORAGE",
      "direction": "in"
    },
    {
      "name": "outputblob",
      "type": "blob",
      "dataType": "binary",
      "path": "samples-workitems/{queueTrigger}-Copy",
      "connection": "nameofstorageaccount_STORAGE",
      "direction": "out"
    }
  ],
  "disabled": false,
  "scriptFile": "__init__.py"
}

init.py


import logging
import azure.functions as func


def main(queuemsg: func.QueueMessage, inputblob: bytes, outputblob: func.Out[bytes]):
    logging.info(f'Python Queue trigger function processed {len(inputblob)} bytes')
    outputblob.set(inputblob)

如果我没理解错的话，这个函数应该在一个 blob 被添加到一个容器时被触发，并且它会在同一个容器中保存那个 blob 的副本。

函数运行，但是当 blob 上传到容器时没有任何反应？我想用正在上传的 blob 触发一些代码，这是我用 Python 和 Blob Trigger.

找到的唯一完整示例

感谢任何帮助，谢谢！ :)

没有。如果您阅读 document，它指出当消息发送到队列时触发该函数：

The following example shows blob input and output bindings in a function.json file and Python code that uses the bindings. The function makes a copy of a blob. The function is triggered by a queue message that contains the name of the blob to copy. The new blob is named {originalblobname}-Copy.

如果要在创建 blob 时执行函数，请参阅此处的 Blob Trigger 示例：https://docs.microsoft.com/en-us/azure/azure-functions/functions-bindings-storage-blob-trigger?tabs=python.
