Agenda • Brief introduction to REST • Brief introduction to JSON • Stand-Alone vs ISAPI Service Blog Notes: embt. co/sprint-rest-json-services • • • Create Read Update Delete Q&A – (POST) – (GET) - (PUT) – (DELETE)

Brief Introduction – to REST • REST is an abbreviation of ”Representational State Transfer” • Layered System • Stateless Client/Server model. No state maintained on the server. • Uniform Interface Blog Notes: embt. co/sprint-rest-json-services A client does not know if it is connected to the end-server or some intermediary. Separation of concern between the client and server implementations.

Brief Introduction – to REST – Over HTTP (CRUD) • HTTP GET = READ Retrieves a collection of resources as a list of the URI’s and other details for each resource. • HTTP PUT = UPDATE Replaces the entire collection with another collection. Blog Notes: embt. co/sprint-rest-json-services • HTTP POST = CREATE Create a new entry in the collection. • HTTP DELETE = DELETE Delete the entire collection.

Brief Introduction – To JSON • JSON stands for Java. Script Object Notation. • Originally derived from the Java. Script scripting language. It is a language independent format, now commonly used in client-server communications. Blog Notes: embt. co/sprint-rest-json-services • JSON primarily consists of a series of comma separated Name: Value pairs. • Can group data as ‘objects’ using braces ‘{’. . ’}’ • Can convey arrays of values or objects using brakets ‘[‘. . ’]’

Brief Introduction – To JSON Some example JSON taken from the JSON Wikipedia page: https: //en. wikipedia. org/wiki/JSON Blog Notes: embt. co/sprint-rest-json-services { "first. Name": "John", "last. Name": "Smith", "is. Alive": true, "age": 25, "address": { "street. Address": "21 2 nd Street", "city": "New York", "state": "NY", "postal. Code": "10021 -3100" }, "phone. Numbers": [ { "type": "home", "number": "212 555 -1234" }, { "type": "office", "number": "646 555 -4567" } ], "children": [], "spouse": null }
