1. Presented by: SIF 3.0 REST URL Structure Components of the SIF3 REST URL Joerg Huber

2. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 2 Components of SIF3 REST Call A SIF3 REST Call can consist of the following parts:  Base URL Segment  Service URL Segment  Matrix Parameters  Query Parameters  Header Fields  Payload  Single-Object vs. Multi-Object URLs

3. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 3 Base URL Segment Retrieved from the “infrastructureService” node with the name “requestConnector” in environment Example http://localhost:9080/SIF3Training/sif3Demo/requests

4. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 4 Service URL Segment  Generally the name of the SIF Object in plural form (append “s”)  Optionally append ‘Id’ of SIF Object or  Optionally append singular form of SIF Object Name Example - StudentPersonal  /StudentPersonals  /StudentPersonals/  /StudentPersonals/StudentPersonal

5. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 5 Matrix Parameters Used instead of Query Parameters because they help in standard caching:  If no ‘?’ (Query Parameter) is used in URL the result can be cached  Matrix Parameters don’t use the ‘?’ but are part of the URL so the data returned can be cached  Notation: ‘; = {; = }’  Used in SIF3 to set the zone and context in a URL If not provided: Default Zone and/or Context is used Example - StudentPersonal  /StudentPersonals;contextId=current  /StudentPersonals/ ;zoneId=4001  /StudentPersonals;zoneId=4001;contextId=current

6. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 6 Query Parameters Everything after a ‘?’ in the URL is referred to as Query Parameter.  Returned data is not cached  Notation: ‘? = {& = }’  Used in SIF3: xQuery Info Example - StudentPersonal  /StudentPersonals?where=

7. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 7 Header Fields SIF3 uses standard and custom HTTP Request/Response header fields.  Not part of the URL  Different header fields for Request and Response Example Standard Header Fields - Request  Authorization (authorisation token)  If-None-Match (caching info) Example Custom Header Fields - Request  generatorId (Optional: Who makes request)  navigationId (query paging support)

8. © Systemic Pty Ltd September 2014 Training Course - Sydney: SIF3 - URL Structure 8 Payload The final part of a SIF3 REST Service call is the actual payload or the XML Message.  Payload is XML for now (JSON later)  Most requests for REST Calls have a payload  Some Request don’t have a payload (DELETE for single object)  Most responses for single-object operations don’t have a payload. Exception: GET  Responses for multi-object operations do have a payload.
