SAS tokens instead of keys in app

[mikaelhogstrom]

It would be really cool if you could use a SAS token (generated elsewhere) instead of storing the account key in the application.

I have a backend where I generate SAS tokens but I don't really know what to do with them, so that's pretty much the functionality I am asking for :)

SAS token support is something I would like to add here... But with .NET 4.6 (Experiment) support looming I have held fire on developing this as it looks like we are close to being able to use the full SDKs now.

Makes sense. I have already jumped ship to 4.6 myself :)

The experimental Unity Azure SDK has been removed from the web, and from what I saw elsewhere, no longer works anyway.

So here's a quick and dirty modification that works for my needs and will hopefully save someone time:

        public void AuthorizeRequest(StorageServiceClient client, Method method, string resourcePath = "", Dictionary<string, string> queryParams = null, Dictionary<string, string> headers = null, int contentLength = 0)
        {
            AuthorizationHeaders authHeaders = new AuthorizationHeaders(client, method, resourcePath, queryParams, headers, contentLength);
            string stringToSign = authHeaders.ToString();
            this.AddHeader("x-ms-date", authHeaders.MSDate());
            this.AddHeader("x-ms-version", authHeaders.MSVersion());

            // NOTE: you'll need to add string SASParams to the client also 
            if (client.SASParams != null)
            {
                this.Request.url = $"{client.Url}{resourcePath}{client.SASParams}";
            }
            else
            {
                string signature = GetSignature(client.Key, stringToSign);
                string authorization = GetAuthorizationHeader(client.Account, signature);
                this.AddHeader("Authorization", authorization);
                Debug.Log("Authorized request url:" + this.Request.url + "\n\nauthorization: \"" + authorization + "\"\nx-ms-date: " + authHeaders.MSDate() + "\nstringToSign:'" + stringToSign + "'");
            }

            if (headers != null)
            {
                this.AddHeaders(headers);
            }
