Blob REST Interface

Blob storage can be accessed through a RESTful interfaceHTTPS PUT, GET, and DELETE operationsOperations abstracted into an API

http://fabrikamlegal.blob.core.windows.net/imagefiles?resttype=container&comp=list

<?xml version="1.0" encoding="utf-8" ?> <EnumerationResults ContainerName="http://fabrikamlegal.blob.core.windows.net/imagefiles"> <Blobs> <Blob> <Name>Banner.jpg</Name> <Url>http://fabrikamlegal.blob.core.windows.net/imagefiles/Banner.jpg</Url> </Blob> <Blob> <Name>Boy_And_Gift.png</Name> …

Blob REST API – Creating Containers

API is a wrapper around RESTful serviceMakes it easy to call operations

CloudStorageAccount acct = CloudStorageAccount.FromConfigurationSetting( "DataConnectionString");

CloudBlobClient client = acct.CreateCloudBlobClient();CloudBlobContainer con = client.GetContainerReference("videofiles");con.CreateIfNotExist();

Blob REST API – Writing a Blob

FileStream fs = new FileStream("mov1.avi",…,…,…);

var blob = con.GetBlobReference("mov1.avi");blob.UploadFromStream(fs);blob.Metadata["VideoName"] = "Wildlife.avi";blob.Metadata["Category"] = "Travel";blob.Metadata["DateSubmitted"] = DateTime.Now;blob.SetMetadata();blob.Properties.ContentType = "video/x-msvideo";blob.SetProperties();

Blob REST API – Reading Blobsvar azureBlobs = con.ListBlobs();var listOfBlobs = new List<VideoBlobStorage>();foreach (var blobItem in azureBlobs){ var azureBlobRecord = con.GetBlobReference(blobItem.Uri.ToString()); azureBlobRecord.FetchAttributes(); listOfBlobs (new VideoBlobStorage() { FileUri = blobItem.Uri, VideoName = azureBlobRecord.Metadata["VideoName"], Category = azureBlobRecord.Metadata["Category"], DateSubmitted = azureBlobRecord.Metadata["DateSubmitted"] });}

Demo

Blob Types

Block BlobsBlobs made up of individual “blocks”Optimized for steamingEach block can be 4MB in sizeTotal Blob can be 200 GB in size

Page BlobsBlobs made up of a collection of “pages”Optimized for random read/write operationsPage is a range of data similar to a bufferTotal Blob can be 1 TB in size

Blob Access Control

Public Access ControlAllows unrestricted accessNote that cross-domain calls may still fail

Shared Access SignaturesUses an authentication token valid for a period of timeSignature is appended to URL as query string

Container-Level Access PoliciesAllows the definition of a named access policyPolicy uses Shared Access Signatures

Public Access Control

azureBlobPermissions = new BlobContainerPermissions();azureBlobPermissions.PublicAccess = BlobContainerPublicAccessType.Container;cont.SetPermissions(azureBlobPermissions);

Shared Access Signatures

SharedAccessPolicy policy = new SharedAccessPolicy();policy.Permissions = SharedAccessPermissions.Read;policy.SharedAccessStartTime = DateTime.UtcNow.AddMinutes(-10);policy.SharedAccessExpiryTime = DateTime.UtcNow.AddMinutes(60);String signature =    blob.GetSharedAccessSignature(policy);

Container-Level Access Policies

SharedAccessPolicy policy = new SharedAccessPolicy();policy.Permissions = SharedAccessPermissions.Read;policy.SharedAccessStartTime = DateTime.UtcNow.AddMinutes(-10);policy.SharedAccessExpiryTime = DateTime.UtcNow.AddMinutes(60);String signature =    blob.GetSharedAccessSignature(policy);

azureBlobPermissions = new BlobContainerPermissions();azureBlobPermissions.SharedAccessPolicies.Add("policy1“, policy);cont.SetPermissions(azureBlobPermissions);

Integrating with SharePoint 2010

IFrameIntegrate web roles that use the REST APISimple, but not robust

Silverlight Media Player directly accessing public blobsWCF Web Role Proxy

RESTful interface to blob storage does not support cross-domain callsCreate a simple WCF Web Role to act as proxyHttpWebRequest, WebClient classes

Custom web partsSilverlight applications

WCF Web Role Proxy

Cross Domain CallsNot allowed unless service has ClientAccessPolicy.xml fileAzure does not support uploading this fileCreate WCF Web Role and include ClientAccessPolicy.xml

[ServiceContract] public interface IService1 { [OperationContract] [WebGet(UriTemplate = "{Container}")] Stream BlobInfo(string Container); }
