What are REST-ful Services? • RESTful Services REST stands for Representational State Transfer It is not a standard or a RFC, rather it is an architectural style that leverages HTTP(s) protocol • Each unique URI is a representation of a resource • APIs based on four http verbs: GET, PUT, POST, DELETE to manipulate the resources defined by the URI • Responses can use XML or JSON • • • Java. Script Object Notation (JSON) • A lightweight text-based human readable open standard designed for data interchange

Design and Call Pattern A new Namespace using Microsoft. Xbox; private void Read. Profile() User object encapsulates all user management complexity { IUser signed. In. User = new User(); Async interfaces IAsync. Operation<IUser. Profile> async. Profile = signed. In. User. Get. Profile. Async(); async. Profile. Completed = new Async. Operation. Completed. Handler<IUser. Profile>(Get. Profile. Complete); async. Profile. Start(); Use Delegates to handle callbacks } private void Get. Profile. Complete(IAsync. Operation<IUser. Profile> p. Async) { IUser. Profile profile = p. Async. Get. Results(); this. motto = profile. Motto; } Handle returned data – Property Bag in most cases

Reading Profile data (C++) #using <Microsoft. Xbox. winmd> using namespace Microsoft: : Xbox; void Main. Page: : Get. User. Profile() { Microsoft: : Xbox: : IUser ^user = ref new Microsoft: : Xbox: : User(); auto operation = user->Get. Profile. Async(); operation->Completed = ref new Async. Operation. Completed. Handler<IUser. Profile^>(this, &Main. Page: : Handle. User. Profile. Complete); operation->Start(); } void Main. Page: : Handle. User. Profile. Complete( IAsync. Operation<IUser. Profile^>^ p. Async ) { HResult result = p. Async->Error. Code; IUser. Profile^ profile = p. Async->Get. Results(); if (profile != nullptr) { String^ tag = profile->Gamer. Tag; m_profile = tag; } }

Reading Profile data (Java. Script) var motto; var signed. In. User = new Microsoft. Xbox. User(); signed. In. User. get. Profile(). then( function get. Profile. Completed(profile) { motto = profile. motto; }

Reading Achievements IUser user = new User(); Most interfaces take In-Params to simplify query construction // Get list of achievements IAsync. Operation<IAchievement. Collection> async = user. Get. Achievements. For. Title. Async( title. Id, skip. Elements, top. Elements, unlocked. Only, Achievement. Sort. Type. Title. Id); async. Completed = new Async. Operation. Completed. Handler<IAchievement. Collection>(Get. Achievements. Complete); async. Start(); …

Multiplayer Posting A Matchmaking Request Multiplayer ‘goodies’ namespace using Microsoft. Xbox; using Microsoft. Xbox. Multiplayer; Init the Matchmaking service IMatchmaking. Service matchmaker = new Matchmaking. Service(); Add as many IMatch. Property skill = new Match. Property( "Skill", "Beginner", Match. Type. String); IMatch. Property score = new Match. Property( "Victories", "10", Match. Type. Integer); Match. Properties as you’d like Add the Match. Properties to the Match. Request, including match criteria IMatch. Request request = new Match. Request(); request. Match. Criteria. Equal. Add(skill ); Post the request. Match. Criteria. Less. Than. Add(score ); IAsync. Operation<IMatch. Request. Result> async. Operation = matchmaker. Post. Request. Async(request); async. Operation. Completed = new Async. Operation. Completed. Handler<IMatch. Request. Result>(Post. Request. Complete); async. Operation. Start();

Multiplayer Initiating A Session public void Post. Request. Complete(IAsync. Operation<IMatch. Request. Result> request. Async) A request can be long-lived, use the Request ID to poll for status { this. request = request. Async. Get. Results(); IAsync. Operation<IMatch. Request. Status> status. Operation = this. matchmaker. Get. Request. Status. Async( this. request. Request. Id); status. Operation. Completed = new Async. Operation. Completed. Handler<IMatch. Request. Status>(Get. Request. Status. Complete); status. Operation. Start(); } IMatch. Request. Status property bag represents the match request status public void Get. Request. Status. Complete(IAsync. Operation<IMatch. Request. Status> status. Async) { IMatch. Request. Status status = status. Async. Get. Results(); If a match was found Join current user to the returned Session. Id if (status. Status == Match. Status. Match. Found) { IAsync. Operation<IMultiplayer. Session> join. Operation = this. signed. In. User. Join. Multiplayer. Session. Async( status. Session. Id, 0, custom. User. Data); join. Operation. Completed = new Async. Operation. Completed. Handler<IMultiplayer. Session>(Join. Multiplayer. Session. Complete); join. Operation. Start(); }

Multiplayer Information Exchange private void Join. Multiplayer. Session. Complete (IAsync. Operation<IMultiplayer. Session> async) { Create a Random. Access. Stream to send data this. session = async. Get. Results(); between session members IRandom. Access. Stream data = this. Create. Data. Stream("e 4 e 5"); this. session. Post. Game. Message. Async(0, false, 0, data); } Post data to all session members
