Agenda
• Apps Model Overview
• App Access to SharePoint
– RESTful Access
– Client Side Object Model (CSOM)
– Cross-domain Access
– OAuth Access
• Other Topics

App Hosting Options
App Web Provider or Azure
• Provisioned by SharePoint • Auto-hosted apps are
on app installation provisioned by Office 365
• No Server Code – period on app installation
(though you can leverage • Pretty much
installed ASP.NET controls) Host
anything goes Web
• May contain
declarative, web-scoped • Access host
web via Oauth App
features (lists, site Web
pages, client
script, images, css)
App
• Access host web via cross-
domain library @Bob1German • bobg@bluemetal.com

App Isolation
Host
http://myserver/sites/myweb/
Web

App Web http://app12345/sites/myweb/
(optional)

http://whatevs.com/somepath/
App Azure
or other provider
Different domain names leverage
browsers’ same-origin policy


Isolated Application shows:
- Client Side Object Model
- Declarative features in App Site
- Simple Client Web Part (“App Part”)

App Access to SharePoint


Choosing an App Model
2010 Model 2013 Apps
• Reuse and backward • App code is reusable in
compatibility with existing SharePoint and Office
solutions • Better isolation – no more
• Full access to server OM leftover web parts and lists
– Nearly complete access to • App-level AuthN from Azure
everything in SharePoint or other provider
– Well documented – • No dependency on User
MSDN, many Code Service
books, blogs, etc. • Leverages general web
• Leverages SharePoint development skills
development skills

Choosing an Access Method
REST CSOM
• Synchronous or • Asynchronous only in
asynchronous in Javascript Javascript
• Returns entities (e.g. • Returns SharePoint objects
Contact, Task) (e.g. List, ListItem)
• Easier access from jQuery– • Easier access from .NET
no dependency on SP.JS server side
• Batched requests


Choosing a Hosting Model
SharePoint Hosted Provider / Azure Hosted
• No server side code, period • Server-side code
• Access to OOB SharePoint • Server is not subject to
web controls on the page cross-domain policy
• Able to store content on • More flexible data storage
customer’s SP infrastructure (SQL Azure, etc.)


Accessing Data with Client OM

OData
(REST)


What’s New in CSOM
So much more than simple site and list access!

• User Profiles • Sharing
• Search • Workflow
• Taxonomy • E-Discovery
• Feeds • IRM
• Publishing • Analytics
• Business Connectivity
Services


Silverlight App w/Cross-Domain Policy
• CSOM Cross-domain Access
• CSOM File Upload

Representational State Transfer (REST)

JSON ATOM JSON ATOM

WPF/WinForm/Office
Silverlight
JavaScript

Representational State Transfer (REST)
• Operations map to HTTP verbs
– Retrieve items/lists  GET
– Create new item  POST
– Update an item  PUT or MERGE
– Delete an item  DELETE
– These apply to links (lookups) as well

• SharePoint rules apply during updates
– Validation, access control, etc.


URL Conventions
• Addressing lists and items
List of lists /_api/web/lists
List /_api/web/lists(‘guid’)
List /_api/web/lists/getbytitle(‘Title’)
Items /_api/web/lists/getbytitle('listname')/items
Item /_api/web/lists/getbytitle('listname')/items(1)
Single column /_api/web/lists/getbytitle('listname')/items(1)/fields/getByTitle
('Description')

Sorting ?$orderby=Fullname
Filtering $filter=JobTitle eq 'SDE'
Projection ?$select=Fullname,JobTitle
Paging ?$top=10&$skip=30
Inline expansion ?$expand=Project

Open Authentication
• Standard in use by dozens of public
sites
• Similar to a valet key
– App gives to a partly
trusted 3rd party
– Grants limited access
• SharePoint grants the
app access on the
user’s behalf
– No need to pass the
user’s credentials
– SharePoint can limit the
scope of access


Azure-Hosted App with OAuth
Contacts Map

DEMONSTRATION


Remote Event Receivers
• Require a provider or Azure-hosted app
• Uses Access Control Services (ACS) token
– Passed from SharePoint to remote web service
– Web service can request a token to send back to SharePoint
• SharePoint calls a web service with the following methods:
– ProcessEvent() – Synchronous
– ProcessOneWayEvent() – Asynchronous
• List, ListItem, Web, and App level scopes
• App Events – call AppEventReceiver.svc
– App Installed
– App Uninstalling
– App Upgraded
• Caveats:
– No guaranteed delivery
– Watch latency and performance on synchronous events
