Question

我正在尝试构建一个应用程序，我试图通过ODATA服务获取数据并尝试在SAP UI5中填充表。以下是代码

<script>    
        var oTable = new sap.ui.table.Table({
                                            title: "Outstanding Balance",
                                            visibleRowCount: 5,
                                            //firstVisibleRow: 5,
                                            selectionMode: 
                                            sap.ui.table.SelectionMode.Single

                                        });

    oTable.addColumn(new sap.ui.table.Column({
        label: new sap.ui.commons.Label({text: "CustomerID"}),
        template: new sap.ui.commons.TextField().bindProperty("value",                                             "Customer"),
    //  sortProperty: "Customer",
        //filterProperty: "Customer",
        width: "200px"
    }));

    oTable.addColumn(new sap.ui.table.Column({
        label: new sap.ui.commons.Label({text: "Name"}),
        template: new sap.ui.commons.TextField().bindProperty("value", "Name"),
        //sortProperty: "Name",
        //filterProperty: "Name",
        width: "100px"
    }));

    var oModel = new sap.ui.model.odata.ODataModel(
    "/sap/opu/odata/sap/Z_ATC_CUSTOMER_OUTSTANDING_SRV",true,"ABCD","1234");
    oTable.setModel(oModel);
    // bind path of oDataModel to table rows
        oTable.bindRows("/CUSTOMERSet");
    oTable.placeAt("content");
        //}


//  })

请帮助我，我错了。我的代码在服务器中正常运行，但表中没有填充任何数据。

你的代码使用Northwind通过Heroku代理在我这边工作，所以你的代码和绑定都没问题。

当您在代码中对服务URL进行硬编码时，如果您正在访问服务的正确位置，请检查HTTP跟踪。

在跟踪中查找请求，在＆＃34;标题＆＃34;中获取您要访问的URL。选项卡并在新选项卡中打开它。如果那里有空数据，则问题出在Gateway / OData服务中。如果您有错误，可能是您正在访问错误的路径。查看图片

Gateway Odata服务不在SAP UI5中从后端返回数据
