封装axios

import axios from 'axios'

let baseURL = 'http://localhost:8090'
const instance = axios.create({
    baseURL: baseURL,
    timeout:7000,
    headers:{}
})

//请求拦截器
instance.interceptors.request.use(function(config){
    config.headers.Authorization = localStorage.getItem('token') || ''
    return config;
},function(error){
    return Promise.reject(error);
})

//响应拦截器
instance.interceptors.response.use(function(response){
    if(response.status === 200){
        if(response.data && response.data.msg){
            return response.data.data
        }else{
            alert('网络异常')
        }
    }
},function(error){
    return Promise.reject(error)
})
export default instance
