watch:{
	'$store.getters.getUserId' : function(val){
		//获取Id
		let userId = this.$store.getters.getUserId;
		console.log("当前用户：" + userId  + "ID：" + val);
	},
	$route:{
		handler:function (val, oldVal) {
			console.log("路由发生了变化 原来路由：" );
			console.log(oldVal);
		console.log("新路由：" );
			console.log(val);
		}
	}
