将多个blob输入azure函数python

Question

我正在python中为Azure函数工作。我试图读入两个blob，一个是触发的，一个是静态的

当我读入它们时，两个blob都指向触发的blob（URI相同）。如何正确输入和使用两个blob

我的绑定看起来像：

{
      "name": "techdatablob",
      "type": "blobTrigger",
      "direction": "in",
      "path": "path1/{name}",
      "connection": "example"
    },
    {
      "name": "crmdatablob",
      "type": "blob",
      "direction": "in",
      "path": "path2/data.xlsx",
      "connection": "example"
    },
    {
      "name": "outputblob",
      "type": "blob",
      "direction": "out",
      "path": "path3/out.xlsx",
      "connection": "example"
    }

而init.py文件以以下开头：

def main(techdatablob: func.InputStream, crmdatablob: func.InputStream, outputblob: func.Out[func.InputStream]):
    logging.info(f"Python blob trigger function processed blob \n"
                 f"Name: {techdatablob.name}\n"
                 f"Blob Size: {techdatablob.length} bytes")

    print(techdatablob.uri)
    print(crmdatablob.uri)

When I read them in, both blobs point to the triggered blob (URI is the same). How can input and use two blobs correctly?

事实上，您已经输入了多个blob，问题来自azure函数blob绑定元数据不是来自函数主机，因此blob名称、blob长度、uri等无法获得正确的值。但事实上，它们的数据是不同的（对象也不同）

您可以执行以下操作进行测试：

import logging

import azure.functions as func


def main(techdatablob: func.InputStream, crmdatablob: func.InputStream) -> None:
    logging.info("  -"+techdatablob.read().decode('utf-8'))
    logging.info("  -"+crmdatablob.read().decode('utf-8'))

我认为问题不在你这边，而是功能设计的问题。使用storage sdk获取元数据应该没有问题
