python - 我尝试使用 python 函数写入 azure blob 存储时遇到 Value 'func.Out' is unsubscriptable

Question

我想使用 Python 中的 Azure Functions 写入 Azure Blob 存储。

我正在使用 Azure Functions 的输出 Blob 存储绑定(bind)。

我的函数.json:

{
  "scriptFile": "__init__.py",
  "bindings": [
    {
      "authLevel": "anonymous",
      "type": "httpTrigger",
      "direction": "in",
      "name": "req",
      "methods": [
        "get",
        "post"
      ]
    },
    {
      "name": "inputblob",
      "type": "blob",
      "path": "{containerName}/{blobName}.json",
      "connection": "MyStorageConnectionAppSetting",
      "direction": "in"
    },
    {
      "name": "outputblob",
      "type": "blob",
      "path": "{containerName}/{blobName}.json",
      "connection": "MyStorageConnectionAppSetting",
      "direction": "out"
    },
    {
      "type": "http",
      "direction": "out",
      "name": "$return"
    }
  ]
}

我的 Python 代码如下所示:

    import logging
    import azure.functions as func
    import azure.storage.blob
    from azure.storage.blob import BlobServiceClient, BlobClient, ContainerClient
    import json, os

    def main(req: func.HttpRequest, inputblob: func.InputStream, outputblob: func.Out[func.InputStream]) -> func.HttpResponse:
        logging.info('Python HTTP trigger function processed a request.')

        # Initialize variable for tracking any changes
        anyChanges= False

        # Read JSON file
        jsonData= json.loads(inputblob.read())

        # Make changes to jsonData (omitted for simplicity) and update anyChanges

        # Upload new JSON file
        if anyChanges:
            outputblob.set(jsonData)

        return func.HttpResponse(f"Input data: {jsonData}. Any changes: {anyChanges}.")

但是，这根本不起作用，并抛出以下错误:

Value 'func.Out' is unsubscriptable
