之前我們都是使用本地JSON來顯示發票清單。這節課我們將調用一個UI5公共的OData Service
1.由于本地開發訪問OData服務https://services.odata.org/V2/Northwind/Northwind.svc/會產生跨域問題，所以這里我們需要使用代理
新建一個終端：執行：npm i -D ui5-middleware-simpleproxy 將此包作為新的開發依賴項安裝在package.json中
2.在ui5.yaml文件中加入

specVersion: '3.0'
metadata:name: ui5.walkthrough
type: application
framework:name: OpenUI5version: "1.134.0"libraries:- name: sap.m- name: sap.ui.core- name: themelib_sap_horizon
server:customMiddleware:- name: ui5-middleware-simpleproxyafterMiddleware: compressionmountPath: /V2configuration:baseUri: "https://services.odata.org"

3.manifest.json調整
