    text
    copied!<p>I am trying to get a shared access signature for a single blob and then download the blob using the REST api. However, I always get a forbidden 403 error message. Both on storage emulator and the cloud. Here is my code:</p> <pre><code>CloudStorageAccount storageAccount = CloudStorageAccount.Parse("myConnectionStringHere..."); CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient(); CloudBlobContainer container = blobClient.GetContainerReference("containerName"); CloudBlob blob = container.GetBlobReference("blobName"); string sasToken = blob.GetSharedAccessSignature(new SharedAccessPolicy() { Permissions = SharedAccessPermission.Read, SharedAccessExpiryTime = DateTime.UtcNow + TimeSpan.FromHours(24) } ); string completeUri = string.Format(CultureInfo.InvariantCulture, "{0}{1}", blob.Uri, sasToken); // now use the uri to make the rest call and download HttpWebRequest request = (HttpWebRequest)WebRequest.Create(completeUri); request.Method = "GET"; using (HttpWebResponse resp = (HttpWebResponse)request.GetResponse()) { using (Stream s = resp.GetResponseStream()) { using (FileStream fs = new FileStream("test.jpg", FileMode.Create, FileAccess.Write)) { byte[] buffer = new byte[8 * 1024]; int len; while ((len = s.Read(buffer, 0, buffer.Length)) &gt; 0) { fs.Write(buffer, 0, len); } } } } </code></pre> <p>I keep getting the 403 error when invoking GetResponse. Any help appreciated!</p> <p>EDIT: forgot to mention: I am using the latest azure sdk (2.0)</p> <p>EDIT 2: I experimented a lot and found a tool called Azure Management Studio. This tool is able to create an SAS token. I did that, and used it with my REST call code. This worked just fine, so the error has to be inside the token creation code I have written. However, the format of the sas string is exactly the same. I don't know what else to try out</p>
