这里就不详细说明了，举个例子

var param = new URLSearchParams();
        param.append("productId",this.$route.params.id)
        this.axios({
            url:"http://39.106.44.63:10086/loadAllProduct",
            method:"post",
            data:param
        }).then((data)=>{
            this.loading=false;
            this.arr=data.data.queryResult.list;
            this.arr2=data.data.queryResult.list[0].pictureList
            console.log(this.arr2)
            console.log(this.arr)
        })
