SAPUI5 1.71.78老版本的消费restful服务

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)
			});
		}
	});

});
