问题 I'm using python 3.6 in visual studio and I want to download all blobs files from my azure container in single folder. This is my code but the problem is, that it downloads 1 blob file in the folder and then when downloading the second file it overwrite the first file and in the end I only have the last blob in my local folder. How can I download all the blobs files at once in a single folder? from azure.storage.blob import BlockBlobService block_blob_service = BlockBlobService(account_name

问题 I am pretty new to the world of MS Azure. I am trying to get the filenames and the last modified date for a bunch of files (block blobs) kept in my blob storage using Python. Here is the code that I am using: import datetime from azure.storage.blob import BlockBlobService blob_service = BlockBlobService(account_name=account, account_key=acckey,protocol='http', request_session=sess) blob_service.get_blob_to_path(container, pdfname, pdflocal) generator = blob_service.list_blobs(container)

问题 We have a requirement to create large (1G-16G) row data reports compress and encrypt them. Our customers will consume those reports over sFTP. We are replacing an existing implementation so our customer should get this change transparently. Azure Blob service does not expose sFTP service so we will need some way to facade it with sFTP service. Something similar to FTP to Azure Blob Storage Bridge based on worker role. The worker role will expose sFTP endpoint to the outside world. We will

问题 I know how to save Streams, but I want to take that stream and create thumbnails and other sized images, but I don't know how to save a byte[] to the Azure Blob Storage. This is what I'm doing now to save the Stream: // Retrieve reference to a blob named "myblob". CloudBlockBlob _blockBlob = container.GetBlockBlobReference("SampleImage.jpg"); // upload from Stream object during file upload blockBlob.UploadFromStream(stream); // But what about pushing a byte[] array? I want to thumbnail and do

问题 I was experiencing a problem with a logic app which Used the Create SAS URI by path action to get a SAS-enabled URL for a blob in a storage account Used the SFTP copy file action to copy the file to an SFTP connector The process would fail roughly 50% of the time with an authorization error when trying to fetch the blob from storage. "actions": { "Create_SAS_URI_by_path": { "inputs": { "body": { "Permissions": "Read" }, "host": { "connection": { "name": "@parameters('$connections')['azureblob

问题 I'm in the process of making an MVC Windows Azure website which involves users uploading images. I wanted to store the images in blobs. I searched for tutorials but most of them deal with Webapps rather than MVC websites.

问题 What is the difference between OpenReadAsync and DownloadToStreamAsync functions of CloudBlockBlob in the Azure blob storage? Searched in google but could not find an answer. 回答1: Both OpenReadAsync and DownloadToStreamAsync could initiate an asynchronous operation for you to retrieve the blob stream. Based on my testing, you could have a better understanding of them by the following sections: Basic Concepts DownloadToStreamAsync：Initiates an asynchronous operation to download the contents of

问题 One of my concerns about using Azure Blob Storage is hotlinking. It looks like a good idea to put static content (images, videos, audio, large JS and CSS files, etc..) in a public container, but then nothing stops other websites to link this content and use it in their websites. Therefore, some webmasters using my content in their sites, would cost me money. A common protection for hotlinking is to filter by the Referer HTTP header. How can this be accomplished in Microsoft Azure Blob Storage
