Introduction

Azure Blob Storage is a great basis to store or buffer files for an application with document management functionality. On this base you may set up a Cognitive Search instance to provide search functionality and you also can generate download URL’s with limited accessebility (regarding e.g. time or IP address of clients). For such a solution you usually build sort of a synchronisation service which stages the document from a source system. This snippet provides a simple, trigger based function which you can use for this. It shows:

• Copy files to a blob (from a ZIP file)
• Ensure that corrent content-type is set
• Add metadata to blobs which can be used in e.g. a document overview or in a Cognitive Search index

Getting Started

Ensure that following Nuget packes are installed:

• Microsoft.NET.Sdk.Functions (tested with 3.0.11)
• Azure.Storage.Blobs (tested with 12.8.0)
• MimeMapping (tested with 1.0.1.37)
• For sample with download of a web resource: Flurl.Http (tested with 3.0.1)

Then you can adapt the function CopyFilesFunc in your Function App.
