电网面板没有渲染存储在Ext JS 6.0.0中

Question

我正在研究书籍'掌握ext js'，我在网格面板上遇到问题，没有从商店加载数据，我的debug json格式服务器却很好，我不知道问题是什么由于控制台没有错误。

这是我的模型类

Ext.define("pg.model.security.User", {
extend: 'Ext.data.Model',
idProperty: 'userName',
fields: [
    {
        name: 'userName'
    }, {
        name: 'roleId'
    }, {
        name: 'fullName'
    }, {
        name: 'emailId'
    }, {
        name: 'mobileNumber'
    }, {
        name: 'landLineNumber'
    }, {
        name: 'picture'
    }
]
});

这是商店类

Ext.define('pg.store.security.Users', {
extend: 'Ext.data.Store',
requires: [
    'pg.model.security.User' // #1
],
storeId:'userStore',    
model: 'pg.model.security.User', // #2
proxy: {
    type: 'ajax',
    url: 'http://localhost:8080/parkgarau-ws/ws/park/userlist',
    reader: {
        type: 'json',
        root: 'data'
    }
}
});

来自URL，我将成功检索JSON格式

{"代码"：200，"消息"："成功"，" data"：" [{{" username "：" admin "，" roalid "： sys_admin "，" fullname "：" bibek shakya "，" emailId "：" [e-mail] "，" mobilenumber "：" 98443598726： " 014323565 "，"图片"：" index.jpg "}]"}

这是我的视图类扩展网格面板

Ext.define('pg.view.security.UsersList', {
extend: 'Ext.grid.Panel',
alias: 'widget.userslist',
frame: true,
store: Ext.create('pg.store.security.Users'), // #1
columns: [
    {
        width: 150,
        dataIndex: 'userName',
        text: 'Username'
    },
    {
        width: 200,
        dataIndex: 'fullName',
        flex: 1,
        text: 'Name'
    }, {
        width: 250,
        dataIndex: 'emailId',
        text: 'Email'
    }
]
 });

这是我的控制器类

Ext.define('pg.controller.security.Users', {
extend: 'Ext.app.Controller',
views: [
    'security.Users' // #1
],
init: function (application) {
    this.control({
        "userslist": {// #2
            render: this.onRender
        }
    });
},
onRender: function (component, options) { // #3
    this.getStore('userStore').load();
}
});

Answer 1

我弄清楚问题是什么，问题是在JSON格式上，如果格式包含'/'，则不会解决

{
 "code":200,
 "message":"Success",
 "data":"[{"userName":"admin","roleId":"SYS_ADMIN","fullName":"Bibek Shakya","emailId":"[e-mail]","mobileNumber":"9843598726","landLineNumber":"014323565","picture":"index.jpg"}]"}

但是，有了清晰的JSON格式，它运行良好

[{"userName":"admin","roleId":"SYS_ADMIN","fullName":"Bibek Shakya","emailId":"[e-mail]","mobileNumber":"9843598726","landLineNumber":"014323565","picture":"index.jpg"}]
