Question

我正在尝试使用以下C ++代码（从官方文档here引用）将文件上传到我的azure文件服务中：

const utility::string_t storage_connection_string(U("DefaultEndpointsProtocol=https;AccountName=myaccount;"
    "AccountKey=mykey"));

// Retrieve storage account from connection string.
azure::storage::cloud_storage_account storage_account =
  azure::storage::cloud_storage_account::parse(storage_connection_string);

// Create the Azure Files client.
azure::storage::cloud_file_client file_client =
  storage_account.create_cloud_file_client();

// Get a reference to the share.
azure::storage::cloud_file_share share =
  file_client.get_share_reference(_XPLATSTR("myfileservice"));

//Get a reference to the root directory for the share.
azure::storage::cloud_file_directory root_dir = share.get_root_directory_reference();

// Upload a file from a file.
azure::storage::cloud_file file =
  root_dir.get_file_reference(_XPLATSTR("my-sample-file"));
file.upload_from_file(_XPLATSTR("test.pdf"));

这会发出以下错误：

terminate called after throwing an instance of 'azure::storage::storage_exception'

what():  Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature.

我搜索了互联网，发现它应该与使用SAS的身份验证相关。我在线尝试了很多示例代码，但仍然无法成功。

但是，我可以通过以下 Python 代码without SAS authentication进行类似的文件上传，并且没有任何问题：

import os
from azure.storage.file import FileService, ContentSettings

currentDir = os.path.dirname(os.path.abspath(__file__))

#credentials for azure account
file_service = FileService(account_name='myaccount', account_key='mykey')

#path for azure file
global pathStr
pathStr = 'https://myaccount.file.core.windows.net/myfileservice/'

#function for uploading file onto Azure container
def upload(myfile):
    file_service.create_file_from_path(
        'myfileservice',
        'files',
        test + '.pdf',
        myfile,
        content_settings=ContentSettings(content_type='text/pdf')       
        )
print('finished uploading file.')

这可能是什么解决方案？
