example / explanation for push request ?

Hi,

can someone provide me a working example of soure code which creates a push request (Header + body) to an existing SAP NetWeaver Gateway Service?  My goal is to read a textfield input and transfer this information to an existing Service.

<Label text="PO number"/><Input id="purchaseOrderInput" type="Text" width="50%" placeholder="Enter a PO number ..."/><Label text="Reason" required="true"/><Input id="reasonInput" type="Text" width="80%" placeholder="Enter a Reason ..."/>

-<c:MatrixLayout id="matrix">     -<c:MatrixLayoutRow>          -<c:MatrixLayoutCell hAlign="Right">               <Button text="Close" press="onClose"/>          </c:MatrixLayoutCell>          -<c:MatrixLayoutCell hAlign="Left">              <Button text="Open" press="onOpen"/>          </c:MatrixLayoutCell>     </c:MatrixLayoutRow></c:MatrixLayout>

onOpen : function(oEvent) {  var purchaseOrder = this.getView().byId("purchaseOrderInput")  .getValue();  var reason = this.getView().byId("reasonInput").getValue();  if (purchaseOrder == null || purchaseOrder == '') {  var msgClose = 'Please enter a Purchase Order!';  sap.m.MessageToast.show(msgClose, {  at : "Center"  });  } else {  var msgClose = 'ok! open';  sap.m.MessageToast.show(msgClose, {  at : "Center"  });  }  ;  },

Many thanks

Best regards

Dominik
