    data: {
      productList: [] //作为商品列表

            const _this = this; //这里的this指向vmCart
            axios.get(\'data/cartData.json\') //使用axios
            .then(function(res){  //then回调函数
            // 使用箭头函数的话,this的作用域并不会变,还是指向vmCart
            //     (res)=>{

            // 就必须在mounted钩子函数里再调用一次$nextTick方法才能保证el被render在dom中
                //res 数据库返回的对象
                //res.data.result.list 返回的数据数组
                //console.log(res);
                res.status == 200 && (_this.productList = res.data.result.list ); //状态为200时执行后面语句
            })

3 测试是否获取数据 

获取成功

3.1 接下来故意将axios.then引入.catch回调中看是否有效 

说明有效
