如何通过AJAX调用将菜单项动态添加到getStartConfig？

如何解决如何通过AJAX调用将菜单项动态添加到getStartConfig？

我正在Sencha Ext JS 7.0中创建一个桌面应用程序，登录后，将根据用户的角色和权限级别加载模块。

它必须替换左侧的“主页”和“设置”项：

我有一个正确返回模块的AJAX调用：

userModuleMenu: function()
{
    Ext.Ajax.request(
    {
        url: 'ajax_url',method: 'POST',cors: true,useDefaultXhrHeader : false,params: 
        {
            module: 'module_name',action: 'get_modules',user_id: userid
        },success: function(response,xhr,status)
        {
            //  If call was successful
            var result = JSON.parse(response.responseText);
            var resultType;
            if(result.success)
            {
                //  The menu
                var moduleMenu = result.result;
                return moduleMenu;
            }
            else
            {
                resultType = 'Failed';
                Ext.Msg.alert(resultType,result.result,function(btn,text)
                {
                    if(btn == 'ok')
                    {
                    }
                });
            }
        },failure: function(response,status) 
        {
            Ext.Msg.alert('Failed','failed');
        },scope: this
    });
},

哪个返回这样的数组：

0: {...}
    handler: "AccountInformation"
    ​​iconCls: null
    ​​scope: "me"
    ​​text: "Account Information"
    ​​
1: {...}
    ​​handler: "AccountDetails"
    ​​iconCls: "mol_accountdetails"
    ​​scope: "me"
    ​​text: "Account Details"
    ​​
2: {...}
    ​​handler: "ContactYourAdministrator"
    ​​iconCls: "mol_feedback"
    ​​scope: "me"
    ​​text: "Contact Your Administrator"
    ​​
3: {...}
    ​​handler: "ChangePassword"
    ​​iconCls: "mol_password"
    ​​scope: "me"
    ​​text: "Change Password"
    ​​
4: {...}
    ​​handler: "Administration"
    ​​iconCls: null
    ​​scope: "me"
    ​​text: "Administration"
    ​​
5: {...}
    ​​handler: "AccountConfiguration"
    ​​iconCls: "bo_account_management"
    ​​scope: "me"
    ​​text: "Account Configuration"

这就是我重写getStartConfig（）的方式：

getStartConfig: function() 
{
    var me = this,ret = 
        {
            app: me,menu: [
            {
                text: 'Home',iconCls: 'x-fa fa-home',handler: me.onHome,scope: me
            },{
                text: 'Settings',iconCls: 'x-fa fa-cogs',handler: me.onSettings,scope: me
            }],};

    return Ext.apply(ret,{
        title: 'Menu',iconCls: 'x-fa fa-user',height: 400,toolConfig: {
            width: 100,items: [
                {
                    text: 'Settings',scope: me
                },'-',{
                    text: 'Logout',iconCls: 'x-fa fa-sign-out-alt',handler: me.userStoreRemove,scope: me
                }
            ]
        }
    });
},

如何使用AJAX调用作为存储来填充getStartConfig（）覆盖中的菜单项？
