Overview
The SAP Cloud Platform UserAPI provides a service which can be used to access details of the logged in user. The details of this service can be found at
https://help.hana.ondemand.com/help/frameset.htm?1de599bf722446849d2b2e10132df42a.html
This service is available to html5 applications running on the Cloud Platform. For an example of utilizing it in a html5 application see
https://blogs.sap.com/2015/04/16/using-the-hcp-user-api-in-web-ide/
To utilize this service in a Mobile Services application we can perform the following
STEP 1: Create HTML5 App
To utilize this service in Mobile Services we first need to create an html5 app that exposes access to the service. The only requirement for this app is to have a route defined in it's neo-app.json for the userapi service. You can either follow the above mentioned blog, add to any existing app running on the Cloud Platform or create a new UI5 app in Web IDE and add the following entry in the neo-app.json
{
"path": "/services/userapi",
"target": {
"type": "service",
"name": "userapi"
}
}
After making the change deploy the app to the Cloud Platform. This can be done in Web IDE by right clicking on the app and choosing Deploy -> Deploy to SAP Cloud Platform. In my case I have provided the app name
userapi.
STEP 2: Add connection in Mobile Services Development & Operations
In Mobile Service for Development and Operations choose the menu option
Connections. Add a new connection that points to your app with
/services/userapi appended to the url as shown
Add this connection to the desired application by choosing the tab
Back End of the desired application and adding the connection to the
Application Connections section
STEP 3: Finalize/Test Mobile Services Application
This scenario requires that you are using SAML authentication for the Mobile Services application. This can be done by setting the
Security Configuration property, found under the
Information tab, of the app to
Form. For more information regarding the use of SAML with Kapsel application see
https://blogs.sap.com/2017/02/02/appendix-d-saml/
You should now be able to use this connection within your Kapsel app. An example of accessing the CurrentUser would be as follows.
