我正在创建一个可以将文件上传到我的 Azure Blob 的 Flask 应用程序。当我在我的 python virtualenv 上本地测试代码时，该应用程序运行完美。当我创建一个 docker 容器并将图像推送到 Azure 应用服务时，容器日志显示以下错误:

我已经尝试了 Github 问题和其他类似 stackoverflow 查询中提到的多种解决方案。通常的建议是安装 azure-storage < 0.36，安装 azure==0.11.1 等，但都没有解决我的问题。 https://github.com/Microsoft/AzureNotebooks/issues/460 https://github.com/Azure/azure-sdk-for-python/issues/3623
#azure==0.11.1
#azure==2.0.0
click==6.7
Flask==0.12.2
itsdangerous==0.24
Jinja2==2.10
MarkupSafe==1.0
Werkzeug==0.14.1
#azure-common==1.1.3
#azure-nspkg==1.0.0
azure-storage==0.31.0
futures==3.0.5
python-dateutil==2.5.3
requests>=2.20.0
six==1.10.0
任何人都可以帮助我了解此问题的原因。
编辑:根据其中一条评论的要求添加我的代码:
import os
from flask import Flask, request, redirect, url_for
from werkzeug import secure_filename
from azure.storage.blob import BlockBlobService
from azure.storage import CloudStorageAccount
from azure.storage.blob import ContentSettings
import string, random, requests
import traceback
import mimetypes
app = Flask(__name__, instance_relative_config=True)
account = 'fileupoader' # Azure account name
key = 'some_key' # Azure Storage account access key
container = 'files'
blob_service = BlockBlobService(account_name=account, account_key=key)
#print (blob_service)
@app.route('/', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
f = request.files['file']
mime_type = f.content_type
print (mime_type)
#print (type(f))
try:
blob_service.create_blob_from_stream(container, f.filename, f,
content_settings=ContentSettings(content_type=mime_type))
except Exception as e:
print (str(e))
pass
ref = 'https://'+ account + '.dfs.core.windows.net/' + container + '/' + f.filename
print (ref)
return '''

return '''

app.run(debug=True)
请您参考如下方法:
azure-storage 已弃用，请勿使用，但具体版本如下三个:
- https://pypi.org/project/azure-storage-queue/
- https://pypi.org/project/azure-storage-file/
- https://pypi.org/project/azure-storage-blob/
也不要使用 azure，因为它只是一个元包，带来其他但不包含代码。如果您直接使用服务特定包，如 azure-storage-queue(推荐)
(我在 MS 的 SDK 团队工作)
