导入错误：无法从“azure.core.pipeline.transport”导入名称“RequestsTransport”导入RequestsTransport，HttpTransport

Question

Traceback (most recent call last):

    from ._queue_client import QueueClient

ImportError: cannot import name 'RequestsTransport' from 'azure.core.pipeline.transport' (C:\Users\AZ\AppData\Local\Programs\Python\Python310\lib\site-packages\azure\core\pipeline\transport\__init__.py)

Process finished with exit code 1

我有azure-core==1.31.0，azure-storage-blob==12.19.0 天蓝色存储队列==12.1.6

我已经在 base_client.py 文件中验证了它正在导入“from azure.core.pipeline.transport import RequestsTransport, HttpTransport”。还是失败了

确保项目中的文件名与您正在使用的模块名称不匹配。在这种情况下，重命名文件可以解决问题。

重新安装

Azure-Core

模块，其版本包含

RequestsTransport

以确保兼容性（或）创建新的虚拟环境并重新安装最新版本的所有必需模块。

我创建了一个 Python Azure 函数并安装了以下模块。

需求.txt：

• 安装最新版本的模块。

azure-functions
azure-core
azure-storage-blob
azure-storage-queue

示例代码：

import  azure.functions  as  func
import  logging

from  azure.storage.blob  import  BlobServiceClient, BlobClient, ContainerClient
from azure.storage.queue import QueueServiceClient, QueueClient
from  azure.core.exceptions  import  AzureError

@app.route(route="http_trigger", auth_level=func.AuthLevel.ANONYMOUS)
def http_trigger(req: func.HttpRequest) -> func.HttpResponse:
    try:
        blob_data = req.get_body() 
        blob_name = "sample-blob.txt"
        blob_client = blob_service_client.get_blob_client(container=container_name, blob=blob_name)
        blob_client.upload_blob(blob_data, overwrite=True)

        logging.info(f"Blob uploaded successfully: {blob_name}")

        message = "New blob uploaded: " + blob_name
        queue_client.send_message(message)
        logging.info(f"Message sent to queue: {message}")

        return func.HttpResponse(f"Blob uploaded and message sent: {message}", status_code=200)

    except AzureError as e:
        logging.error(f"Azure Error occurred: {str(e)}")
        return func.HttpResponse(f"Azure error occurred: {str(e)}", status_code=500)

    except Exception as e:
        logging.error(f"An unexpected error occurred: {str(e)}")
        return func.HttpResponse(f"An unexpected error occurred: {str(e)}", status_code=500)
