Chapter 3: Creating Mobile Services Using a REST client to invoke a Mobile operation Once you have constructed the correct URI for the REST resource that represents a given Mobile operation, you can specify it as part of the HTTP request to invoke the operation from a REST client, such as Postman. However, a REST client requires four basic pieces of information to send an HTTP request: • URI — As described in the previous section • Media type — Always application/json for Mobile operations • HTTP method — As specified for each Mobile operation: – Create — POST – Read — GET – Update — PUT (with no op-element in the URI—see previous section) – Delete — DELETE – Invoke — PUT (for all invoke operations, each of which is identified and distinguished from the others by the name of the implementing ABL routine specified as the op-element in the URI—see previous section) • Other HTTP request components — Especially other INPUT parameters to include in the body of the HTTP request Note that, other than the filter parameter that is passed as the op-element in the URI of a Mobile read operation request (see previous section), all other INPUT (and the input side of INPUT-OUTPUT) parameters passed to the implementing ABL routines for Mobile operations are passed in the body of the HTTP request. This includes the JSON object for an INPUT-OUTPUT temp-table or ProDataSet parameter that is passed for the Mobile create, update, and delete operations, and a JSON object with properties for passing the values of any INPUT and INPUT-OUTPUT parameters for Mobile invoke operations. For the REST client, the input JSON objects specified for relational data must conform to the structure defined by OpenEdge for passing the JSON representations of temp-tables and ProDataSets, as appropriate. For more information, see OpenEdge Development: Working with JSON. Note that this structure is similar to the structure used to return the data for a Mobile read operation (GET). For an invoke operation, the property names in the simple JSON object must have the same case-sensitive names as the corresponding parameters defined in the implementing ABL routines. Note also that for the Mobile create, update, and delete operations, all of which have the same type of input JSON object for relational data, only the HTTP method specified for the HTTP request distinguishes one Mobile operation from the other. 86 OpenEdge ® Development: Mobile Applications
Creating Mobile Apps using JSDOs OpenEdge ® Development: Mobile Applications 87 4 As described in Chapter 1, “OpenEdge Mobile Overview,” OpenEdge Mobile supports the development of Mobile Apps with access to OpenEdge data resources on an AppServer using OpenEdge JavaScript data objects (JSDOs), which are instances of the OpenEdge JavaScript class, progress.data.JSDO. With the help of additional OpenEdge JavaScript classes and objects, JSDOs access these data resources through Mobile services running on a Web server and make that data available through the Mobile App. For a reference to the basic OpenEdge JavaScript classes and objects available for access in Mobile Apps, see Appendix B, “OpenEdge JavaScript Class and Object Reference” and Appendix C, “OpenEdge JavaScript Class Properties, Methods, and Events Reference.” The Progress OpenEdge Mobile App Builder, which provides advanced support for building OpenEdge Mobile Apps, supports additional built-in client services for managing JSDOs. Using OpenEdge Mobile, you can build two basic types of Mobile Apps that access the same Mobile resources, but which run on different types of client platforms: Mobile Web Apps that run in a Web browser on any client platform or device, and Mobile Native Apps, packaged using hybrid technology, that run in a native device container deployed to either an Apple iOS or Google Android device. You can build these Mobile Apps using the Mobile App Builder, which provides visual services for building Web pages and mapping JSDO data to Web page elements, or you can use basic HTML and JavaScript coding tools, such as those available in Progress Developer Studio for OpenEdge (Developer Studio).
