Upload file with Azure Storage using SAS (Shared Access Signature)

Question

I know that there is library available for uploading the file using Azure Storage. I have refer this for same.

But, they have not give information for how to use SAS

Answer 1

Uploading a pic to BLOB storage . I got it after searching for hours .Take a look :-

Uploading the photo image is a multistep process:

First you take a photo, and insert a TodoItem row into the SQL database that contains new meta-data fields used by Azure Storage. A new mobile service SQL insert script asks Azure Storage for a Shared Access Signature (SAS). That script returns the SAS and a URI for the blob to the client. The client uploads the photo, using the SAS and blob URI.

So what is a SAS?

It's not safe to store the credentials needed to upload data to the Azure Storage service inside your client app. Instead, you store these credentials in your mobile service and use them to generate a Shared Access Signature (SAS) that grants permission to upload a new image. The SAS, a credential with a 5 minute expiration, is returned securely by Mobile Services to the client app. The app then uses this temporary credential to upload the image.
