今天在研究wordpress的导航菜单。经过查询资料发现一个wordpress菜单里面包含了以下内容。可以在网站任何页面来调用菜单内容：

{
    "ID": 10,  //导航的ID
    "post_author": "1",  //添加导航的作者
    "post_date": "2017-12-11 16:39:20",  //添加的时间
    "post_date_gmt": "2017-12-11 08:39:20",  //添加的时间GMT，就是时区不一样
    "post_content": "是大多数都是", //这里同导航的描述，因为后台菜单没有给出都会内容输入框。
    "post_title": "",
    "post_excerpt": "多少倒萨",
    "post_status": "publish",
    "comment_status": "closed",
    "ping_status": "closed",
    "post_password": "",
    "post_name": "10",
    "to_ping": "",
    "pinged": "",
    "post_modified": "2017-12-11 17:24:08",
    "post_modified_gmt": "2017-12-11 09:24:08",
    "post_content_filtered": "",
    "post_parent": 0,
    "guid": "http://ws2.love.com/?p=10",
    "menu_order": 3,
    "post_type": "nav_menu_item",
    "post_mime_type": "",
    "comment_count": "0",
    "filter": "raw",
    "db_id": 10,
    "menu_item_parent": "0",
    "object_id": "2",
    "object": "page",
    "type": "post_type",
    "type_label": "页面", //导航的类型，大概分为 文章、页面、分类、自定义分类等等
    "url": "http://ws2.love.com/sample-page/",  //导航的链接
    "title": "示例页面", //导航的名称
    "target": "", //是否新页面打开
    "attr_title": "多少倒萨",
    "description": "是大多数都是", //导航描述
    "classes": [  //导航里面有多少CLASS
    "head_nav_div_li3", 
    "menu-item",
    "menu-item-type-post_type",
    "menu-item-object-page"
],
    "xfn": "ds", 
    "current": false,
    "current_item_ancestor": false,
    "current_item_parent": false
}
