SAPUI5简单的ajax操作

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

    return Controller.extend("sap.ui.demo.walkthrough.controller.App", {

        onGet : function () {

            jQuery.ajax({
                type: "GET",
                contentType: "application/json",
                url: "http://localhost:8080/",
                dataType: "json",
                async: false,
                success: function(data) {
                    alert(data.processInstanceId);
                }
            });
        },


        onPostApply : function () {

            //var dataJson = '{"companyId":"0001","departmentId":"0001"}'

            jQuery.ajax({
                type: "POST",
                url: "http://localhost:8080/apply",
                contentType : "application/json",
                dataType : 'json',
                data: '{"companyId":"0001","departmentId":"0001"}',
                async: false,
                success : function(data) {
                    alert(data.processInstanceId);
                }
            });

        },



        onPostWorkList : function () {

            //var dataJson = '{"companyId":"0001","departmentId":"0001"}'

            jQuery.ajax({
                type: "POST",
                url: "http://localhost:8080/tasklist",
                contentType : "application/json",
                dataType : 'json',
                data: '{"userId":"0001"}',
                async: false,
                success : function(data) {
                    alert(data[0].userFirstName);
                }
            });

        }
    });

});

在sapui5中使用ajax的时候，需要引入 "sap/ui/thirdparty/jquery"。

如果在测试的时候，遇到了下面的错误，No 'Access-Control-Allow-Origin' header is present on the requested resource.
