应出现此错误。

OData模型v4中不存在读取方法。

见下文: read is not a function in V4

但是,您可以对OData v2执行相同的操作(建议使用OData的方法,因为v4仍然缺少一些功能)

Restrictions with oData V4

oData V2 vs oData V4

不过,如果稍后需要将响应项与表绑定,则可以这样做:

var oModel = new sap.ui.model.odata.v4.ODataModel({
    groupId: "$auto",
    serviceUrl: "url",
    synchronizationMode: "None",
    operationMode: "Server"
  }),
  oSettings = new sap.ui.model.json.JSONModel({
    bOnlyLarge: false,
    bFilterGermany: false
  });
var oTable = new sap.ui.table.Table({
  columns: [{
    label: "ProductName",
    template: new sap.m.Text({
      text: "{Country}"
    }),
    sortProperty: "ProductName"
  }]
});
oTable.setModel(oModel);

oTable.bindRows({
  path: "/Products"
});
