为了兼容老浏览器，没用Javascript的现代fetch api，用的jquery
controller.js代码如下
sap.ui.define([ "sap/ui/core/mvc/Controller", "sap/ui/model/json/JSONModel", "sap/m/MessageToast" ], function (Controller, JSONModel, MessageToast) { "use strict"; return Controller.extend("zfiori_stock.controller.StockList", { onInit: function () { // 初始化stock模型 var oStockModel = new JSONModel([]); this.getView().setModel(oStockModel, "stock"); }, /** * 重置查询条件并清空表格数据 */ _resetQuery: function () { this._clearInputs(); // 清空表格数据 var oStockModel = this.getView().getModel("stock"); oStockModel.setData({}); MessageToast.show("查询条件已重置"); }, /** * 清空所有输入框 */ _clearInputs: function () { this.getView().byId("werksInput").setValue(""); this.getView().byId("matnrInput").setValue(""); this.getView().byId("chargInput").setValue(""); this.getView().byId("lgortInput").setValue(""); }, /** * 获取库存数据 * 兼容Android 8平台的老浏览器 */ _fetchStockData: function () { // 后端API信息 var sUrl = "/api/zbakpda?ACTION=GET_STOCK"; // 从输入框获取查询条件 var oRequestData = { "werks": this.getView().byId("werksInput").getValue(), "matnr": this.getView().byId("matnrInput").getValue(), "charg": this.getView().byId("chargInput").getValue(), "lgort": this.getView().byId("lgortInput").getValue() }; // 显示加载提示 MessageToast.show("正在查询数据..."); // 使用jQuery.ajax以兼容老浏览器 jQuery.ajax({ url: sUrl, type: "POST", data: JSON.stringify(oRequestData), headers: { "Content-Type": "application/json", "Accept-Language": "zh" // "Authorization": sAuthHeader }, // 兼容老浏览器的参数设置 dataType: "json", xhrFields: { withCredentials: true }, timeout: 30000, //通过 jQuery.proxy(fn, this)，强制绑定了函数执行时的 this 上下文为当前控制器。 success: jQuery.proxy(function (oData) { // 将返回数据绑定到stock模型 var oStockModel = this.getView().getModel("stock"); if (oStockModel) { if (oData.length != 0) { MessageToast.show("库存数据获取成功"); } else { MessageToast.show("返回数据为空"); } oStockModel.setData(oData); } }, this), error: jQuery.proxy(function (xhr, status, error) { console.error("获取库存数据失败:", error); console.error("状态码:", xhr.status); // 友好的错误提示 var sErrorMessage = "获取库存数据失败"; if (xhr.status === 401) { sErrorMessage = "认证失败，请检查账号密码"; } else if (xhr.status === 404) { sErrorMessage = "服务器地址错误"; } else if (xhr.status === 500) { sErrorMessage = "服务器内部错误"; } MessageToast.show(sErrorMessage); }, this) }); } }); });xml视图代码
