Question

我试图从IoTMMS（SAP云平台服务）获取OData EntitySet的最后一个条目。

谢谢！

OData API：https://iotmmsUSERtrial.hanatrial.ondemand.com/com.sap.iotservices.mms/v1/api/http/app.svc/SYSTEM.T_IOT_4212F80B4D7D95539D0C
Destination (img)：完整网址：https://iotmmsUSERtrial.hanatrial.ondemand.com/com.sap.iotservices.mms/v1/api/http/app.svc
新app.js

Master.view.xml（绑定工作）

＆＃13;

<mvc:View xmlns:html="http://www.w3.org/1999/xhtml" xmlns:mvc="sap.ui.core.mvc" xmlns="sap.m" controllerName="sensordata_tut.controller.Master" displayBlock="true">
	<App>

			<Page title="{i18n>title}" content="{sensordata>/T_IOT_4212F80B4D7D95539D0C}">

			</content>
			</Page>
		</pages>
	</App>
</mvc:View>

＆＃13;

Master.controller.js

＆＃13;

sap.ui.define([
	"sap/ui/core/mvc/Controller"
], function(Controller) {
	"use strict";

	return Controller.extend("sensordata_tut.controller.Master", {
	    
	    onInit: function() {
           var url = "/com.sap.iotservices.mms/v1/api/http/app.svc";
           var oModel = new sap.ui.model.odata.v2.ODataModel(url);
           console.log(oModel);
	        
	    }
	});
});

为什么要在onInit中创建新模型？如果在清单中定义模型，则会在“组件”级别中设置它。要检索它，并在控制器中使用它，请执行以下操作：

onInit(){
  var myOdataModel = this.getOwnerComponent().getModel("sensordata");
  console.log(myOdataModel);
}
