Of REST and Beans
1 like3,010 views
The document discusses REST (Representational State Transfer) principles and JSON (JavaScript Object Notation) usage in web development. It outlines REST constraints, communication methods, and provides various JSON examples and conversions. The document also distinguishes between JSON and REST, emphasizing the importance of hypermedia in RESTful APIs.

- 5. REST // Definitie Representational State Transfer A set of recommended architectural constraints in order for a system to be described as RESTful Door Roy Fielding, ook HTTP 1.0 en 1.1
- 6. REST // Constraints * Client - Server * Stateless * Cacheable * Layered system * Code on demand * Uniform interface
- 7. REST // Communicatie Data uitwisseling Client doet weergave Server doet opslag
- 8. REST // Communicatie Via HTTP * GET - Ophalen * POST - Aanmaken * PUT - Vervangen * DELETE - Verwijderen Lijkt op CRUD
- 9. JSON
- 10. JSON // Definitie JavaScript Object Notation * lightweight text-data interchange * taal onafhankelijk * "self-describing", easy to understand
- 11. JSON // Voorbeeld Object: { "firstName":"John", "lastName":"Doe" }
- 12. JSON // Voorbeeld Array: [ 100, 200, 300 ]
- 13. JSON // Voorbeeld Array met twee objecten: [ {"firstName":"John", "lastName":"Doe"}, {"firstName":"Hello", "lastName":"World"} ]

- 15. JSON // Conversie Javascript -> JSON XPages: toJson(myObject); Browser: JSON.stringify(myObject);
- 16. JSON // Conversie JSON -> Javascript var myJSON = '{"firstName":"John", "lastName":"Doe"}'; XPages: fromJson(myJSON); Browser: JSON.parse(myJSON);
- 17. JSON // Conversie Test of iets JSON is XPages: isJson('{<some JSON string>}');
