New Plugin: Azure Blob

[mikoskinen]

Plugin which allows file/directory browsing of Azure Blob Storage. Functionality should be similar to the Files-plugin.

This code can be helpful: https://github.com/filipw/Strathweb.AspNetCore.AzureBlobFileProvider/tree/master/src/Strathweb.AspNetCore.AzureBlobFileProvider

This should be done in new repository: ApiFramework.Plugins.AzureBlobs. Use weikio/Template
as the starting point.

Configuration:

• ConnectionString
• Mode: Read, Read & Write

Methods:

• List (string path): returns list of items ("directories" and blobs). At least the following data should be available for each item IF they are available without querying metadata for each blob individually: BlobName, file size, dates (created date, modified date etc).
• Get (string filePath): returns single blob as byte-array. Can we also return a correct mime-type (pdf, txt etc?)
• Save (string filePath, byte[] content): Creates new blob or updates an existing one.
• Delete (string filePath): Deletes blob (doesn't have to support deleting a directory)
