问题 I would like to upload from a web browser a text/html string as an Azure blob directly to Azure storage (without first going thru the Azure VM/webserver) using browser side javascript.

问题 I am using Blobs to store json files for my application. What I am trying to achieve is to request an internal url of my application in order to get the relevant file.

问题 Can any one suggest simple example to fetch the file from my windows azure container and place the file on local machine using SSIS - execute process task 回答1: Based on this article, it seems that standard FTP is an option for you.

Content of the batch would be approximately Executable C:\Windows\System32\ftp.exe Arguments -s:"C:\myFTPcommands.txt'

问题 I want to copy files from an SFTP server to an blob storage by using a logic app. The logic app is triggered by a "recurrence" block every 3 minutes and checks which files are on the server in order to copy them. To check which files are on the server I use the "list files in folder" block. The copying itself is performed by a pipeline run. This works fine so far, but I'm facing one problem. In case one file is still in the uploading process on the sftp server during the logic app is

What's weird is that, if I try running this in the
