axios拦截器

axios.interceptors.request.use(function(request) {
     
	//loading、请求地址替换、修改
	return request;
});
// { code:0,data:'',message:'' }
axios.interceptors.response.use(
	function(response) {
     
		let res = response.data;
		if (res.code != 0) {
     
			alert(res.message);
		}
		return response;
	},
	function(error) {
     
		return Promise.reject(error);
	}
);

怎么和token机制结合起来呢？
