每次请求携带token

instance.interceptors.request.use(config => {
    if (JSON.parse(localStorage.getItem('rl'))) {
	let token = JSON.parse(localStorage.getItem('rl')).data.token
	config.headers.Authorization = token; //将token放到请求头发给服务器
	//axios.defaults.headers.common['Authorization'] = token;
  } else {
	}
	return config
}, err => {
	console.log('错误拦截器', err)
})
instance.interceptors.response.use(res => {
	console.log('响应拦截器');
	return res
}, (err) => {
	console.log('响应错误', err)
})
