axios配置封装

axios.js

// 这里的@符号等于src目录
import axios from 'axios';

// 创建axios实例
const axiosInstance = axios.create({
    // baseURL: env === "development" ? "" : serverUrl
    baseURL:'http://********'
});

// request 拦截器
axiosInstance.interceptors.request.use(
    (config) => {
        if (store.state.token) {
            config.headers['Authorization'] = `wruser ${store.state.token}`
        }
        return config;
    },
    (error)=>{
        return Promise.reject(error);
    }
);

// response拦截器
axiosInstance.interceptors.response.use(
    (response)=>{
        return response.data;
    },
    (error)=>{
        switch(error.request.status){
            case 400:
                Message.error(error.request.response);
                break;
            case 401:
                // 授权过期，暂时先跳转到注册页
                if(router.currentRoute.name!=='login'){
                    router.replace()
