我们开发的这个SAP UI5应用需要消费一个OData服务,请求该服务得到一系列采购订单的数据,再显示到UI5应用上。所以需要先申请该OData服务所在的服务器ES5上的用户。
申请链接:
https://register.sapdevcenter.com/SUPSignForms/
申请完毕后,可以通过webUI进入该系统。
OData服务的地址:
https://sapes5.sapdevcenter.com/sap/opu/odata/sap/SEPMRA_PO_APV/PurchaseOrders?$format=json
登录SAP云平台,创建一个指向ES5的Destination:
打开SAP云平台的WebIDE,新建一个项目,基于template创建一个SAP UI5应用:
右键菜单,新建一个OData服务:
从service catalog的下拉菜单里选择刚刚创建的Destination,能带出该Destination指向的ES5服务器上部署的所有OData服务:
WebIDE会帮我们生成一个UI5应用的骨架,直接点run按钮试着运行:
在Chrome开发者工具里看到OData服务的metadata已经可以成功取回了:
XML视图的实现代码:
<mvc:View controllerName="com.sap.PurchaseOrderApp.controller.Mainview" xmlns:mvc="sap.ui.core.mvc" displayBlock="true" xmlns="sap.m">
<Shell id="shell">
<App id="app">
<pages>
<Page title="Purchase Orders">
<!-- INSERT IN STEP 3 OF THE NEXT TUTORIAL -->
<content>
<List noDataText="No purchase orders found" items="{/PurchaseOrders}">
<StandardListItem type="Navigation" title="{POId}" description="{SupplierName}" press="onClickPO"/>
</List>
</content>
</Page>
<!-- INSERT CODE IN STEP 5.2 HERE -->
</pages>
</App>
</Shell>
</mvc:View>
将上面的xml视图代码实现之后,整个应用的外观如下:
最后通过右键菜单将这个应用从WebIDE部署到SAP云平台:
部署成功:
该应用的controller源代码:
sap.ui.define[
"sap/ui/core/mvc/Controller"
], function Controller) {
"use strict";
return Controller.extend"com.sap.PurchaseOrderApp.controller.Mainview", {
onInit: function ) {
}, // INSERT IN STEP 2 OF THE NEXT TUTORIAL
onClickPO: function oEvent) {
var oApp = this.getView).getContent)[0].getApp);
var sBindingPath = oEvent.getSource).getBindingContext).getPath);
var oDetailsPage = oApp.getPages)[1].bindElementsBindingPath);
oApp.tooDetailsPage.getId));
}
// INSERT CODE IN SUB-STEP 6.2 HERE
});
});
