微信小程序tabbar页面是拥有底部导航栏的页面，实现方法：
在app.json中添加以下代码：
"tabBar": {"list": [
{
"pagePath": "pages/home/home",
"iconPath":"images/tabbar/component.png",
"selectedIconPath": "images/tabbar/component_cur.png",
"text": "首页"
},
{
"pagePath": "pages/register/register",
"iconPath": "images/tabbar/plugin.png",
"selectedIconPath": "images/tabbar/plugin_cur.png",
"text": "发布"
},
{
"pagePath": "pages/register/register",
"iconPath": "images/tabbar/about.png",
"selectedIconPath": "images/tabbar/about_cur.png",

}
]
},
