问题 I'm trying to use the Azure Python API. I followed these installation instructions https://azure.microsoft.com/en-us/documentation/articles/python-how-to-install/ using pip install azure It had no issues. (I ran it again below just to show the message stating that it is installed. ) I want to upload to Storage as described here: https://azure.microsoft.com/en-us/documentation/articles/storage-python-how-to-use-blob-storage/ $ pip install azure Requirement already satisfied (use --upgrade to

问题 There are several ways to copy azure blob storage blocks around. There's a synchronous and asynchronous version of StartCopy . There is also a BeginStartCopy which also has the completion callback. The BeginStartCopy approach explicitly states that the callback is executed when the copy has completed. The StartCopy approaches both state that they return a string, which is a copy process id - they don't state that they return when the copy has completed. Do those StartCopy methods return after

问题 In the software that I am programming, I am attempting to create a virtual file system over the blobs structure of Azure. Many times in the process, I get a path from the system and I need to tell whether the path is of a Blob or just a virtual BlobDirectory that azure provides. I did this by casting it from one form to another and handling the error. But now, if I know that a path points to a virtual directory, how can I check whether this virtual directory exists or not? I can get the

问题 In new Azure portal there are 2 storage account: non classic and classic account. as I think the classic is old version then I choose the non classic. The problem is, I cannot configure the custom domain on the new portal, it redirected me to the old azure portal (manage.windowszuare.com) . and the problem continue.. the old azure portal not recognizing the new/nonClassic Azure storage.

问题 I need to connect to a CSV file in an Azure blob (source), then load the data into an Azure SQL Server table, then move the CSV file to a different (archive) Azure blob. Without Azure, I would create a flat file connection to a local file, then a Data Flow task using Source Assistant & Destination Assistant to load the data into a SQL Server table, then a File System task in Control Flow to move the file to the Archive directory. I'd like to do something similar, with a direct connection to

问题 I am assessing Azure Queue Storage to communicate between two decoupled applications. My requirement is to send a file (flat file, size: small to large) in the queue message. As per my reading an individual message in a queue cannot exceed beyond 64KB, so sending a file of variable size in the message is out of question. Another solution I can think of is using a combination of Queue Storage and blob storage, i.e. in the queue message add a reference to the file (on blob storage) and then

问题 I have a requirement whereby on creation of a company an associated blob storage container is created in my storageaccount with the container name set to the string variable passed in. I have tried the following: public void AddCompanyStorage(string subDomain) { //get the storage account.

问题 I am trying to download a .json blob that I have stored in a container in the Azure Storage using Newtonsoft.Json to write it to an object. I am doing this by calling: (CloudBlockBlob) blob.DownloadToStream(stream); However, instead of writing the stream to a file in the local app directory, I want to return the json object doing Json(result) This is what I have tried: using (var stream = new MemoryStream()) { blob.DownloadToStream(stream); var serializer = new JsonSerializer(); using (var sr

问题 Yesterday I had successfully setup a custom subdomain in Azure storage. I had set up assets.iprobesolutions.com to point to iprobesolutions.blob.core.windows.net. This is a screenshot of my host records CNAME set up: https://www.dropbox.com/s/ndfmn5dd7m48aqg/Screenshot%202016-05-30%2019.36.11.png?dl=0. As I said, this was working fine. Today I decided instead to have iprobesolutions.com point to iprobesolutions.blob.core.windows.net and got as far as Azure accepting the domain using the

问题 I'm trying to download a file from Azure blob and save it locally, but it seems to fail. Here's the relevant code: var blobClientCode = client.CreateCloudBlobClient(); string codeUri = "https://???.blob.core.windows.net/...../mycode.exe"; using (var codeContent = File.OpenWrite("C:\\code.exe")) { blobClientCode.GetBlockBlobReference(codeUri).DownloadToStream(codeContent); } I get an error in which the container doens't exist. What am I doing wrong? 回答1: Try getting a reference to the
