Consuming REST API via destination service in Neo environment?(avoiding direct Ajax calls)

[former_member349501]

Hi All,

I am trying to consume Rest API via destination service in my UI5 application.

But it is giving the following error:

Please find below the steps i followed :

1.Backed system is onPremise system:Hence using cloud connector to establish the connection.

2.Declared Destination in hana cockpit:

3.Defined destination in neo-app.json file.

{ "path": "/P4MSAPI", "target": { "type": "destination", "name": "P4MSAPI" }, "description": "User Data API" }

4.Defined model and datasource in manifest.json file

"P4MSAPI": { "type": "sap.ui.model.json.JSONModel" }

_______________________________________________________________________________________

"sap.app": { "id": "SampleP4MS.SampleP4MS", "type": "application", "i18n": "i18n/i18n.properties", "applicationVersion": { "version": "1.0.0" }, "title": "{{appTitle}}", "description": "{{appDescription}}", "sourceTemplate": { "id": "servicecatalog.connectivityComponentForManifest", "version": "0.0.0" }, "dataSources": { "P4MSAPI": { "uri": "/P4MSAPI/user", "type": "JSON" } } },

5.Trying to directly bind model(P4MSAPI) in view file.

approach 1:

<Title textAlign="Left" titleStyle="H5" text="{P4MSAPI>/name}">

OR approach 2:

// creates a model and attach it to the view

this.getView().setModel(new JSONModel(), "P4MSAPI");

// do a GET request

this.getModel("P4MSAPI").loadData( "/P4MSAPI/user" );

Please suggest what can be done in such case.

Is the destination URL with "https" also correct, or is it only "http" protocol?

Hi All,

Facing 403 error now. Please suggest if any inputs on this issue.

[former_member349501]

As per the current destination configuration settings below mentioned additional properties are being used.

WebIDEUsage:api_mgmt_proxy,api_mgmt_catalog,api_mgmt_proxy,odata_abap,dev_abap,ui5_execute_abap,odata_gen

,bsp_execute_abap

WebIDEnabled: True

WebIDESystem : P4MSAPI

Even if we remove WebIDESystem property still the purpose is not getting resolved.

Please suggest if any other additional properties are to be used for working with rest api or json data?

Do you need the additional properties "WebIDESystem" (because this usually defines the <SAP system_ID>)?
