Question

我正在尝试通过JSON模型加载显示从restdb.io - 数据库中使用的SAPUI5表中的项目。我认为它不起作用，因为一些异步主题，可能数据消耗太晚或类似的东西。如何克服此问题并显示项目？

查看：

<mvc:View
  controllerName="IR_Voting_V1.controller.Main"
  xmlns:mvc="sap.ui.core.mvc"
  xmlns="sap.m"
  displayBlock="true">
  <App>
    <Page title="{i18n>title}">
      <List id="contactList"
        width="auto"
        items="{items>/}">
        <ObjectListItem title="{items>title}" />
      </List>
    </Page>
  </App>
</mvc:View>

控制器：

sap.ui.define([
  "sap/ui/core/mvc/Controller"
], function(Controller) {
  "use strict";

  return Controller.extend("IR_Voting_V1.controller.Main", {
    onInit: function() {
      var sUri = "https://myurl-xxxx.restdb.io/rest/mydb";
      var oHeaders = {
        "Content-Type": "application/json",
        "x-apikey": "myCORSkey",
        "Cache-Control": "no-cache"
      };
      var oModel = new sap.ui.model.json.JSONModel();
      oModel.loadData(sUri, null, true, "GET", null, false, oHeaders);
      console.log("model", oModel);
      sap.ui.getCore().setModel(oModel, "items");
    }
  });
});

console.log中的JSON如下所示：

阵列（7）

0: {_id: "5ae31847b8552b5200008ef0", title: "AA", ident: "IR07", votings: 0}
1: {_id: "5ae317e5b8552b5200008ee7", title: "BB", ident: "IR03", votings: 0}

6: {_id: "5ae31772b8552b5200008edf", title: "GG", ident: "IR01", votings: 0}

尝试直接在视图上设置模型：

this.getView().setModel(oModel, "items");

使用REST服务
