Vue 2.0中封装Axios请求方法_vue2.0axios的写法

import axios from 'axios'
import { Message } from 'element-ui'
 
// 域名地址
axios.defaults.baseURL = '';
 
 
//  REQUEST 请求异常拦截
axios.interceptors.request.use(config => {
    const token = localStorage.getItem('token');
    // 将Token添加到请求头里面
    token && (config.headers.Token = token);
    return config;
}, err => {
    // 错误处理
    Message.error({ message: '请求超时!' });
    return Promise.resolve(err);
});
 
//  RESPONSE 响应异常拦截
axios.interceptors.response.use(result => {
    if (result.data.code && result.data.code != 200) {
        Message.error({ message: result.data.msg });
        // 非法进入时直接跳到登录页
        window.location.href = '/';
        return;
    };
    return result;
}, err => {
 
    if (err && err.response) {
        switch (err.response.status) {
            case 401:
                err.message = '请求方式错误!';
                break;
            case 402:
                err.message = '请求参数错误!';
                break;
            default:
                err.message = `登录凭证过期,请重新登录!`;
        }
    } else {
        err.message = '连接服务器失败!'
    }
 
    Message.error({ message: err.message })
    return Promise.resolve(err);
})
 
// 接口域名
export const url = axios.defaults.baseURL;
 
// POST 方法封装 (处理参数与文件上传)
export const postRequest = (url, params) => {
    return axios({
        method: 'post',
        url: url,
        data: params
    });
}
 
 
//  GET 方法封装

    return axios({
        method: 'get',
        url: url,

}
 
//  PUT 方法封装
export const putRequest = (url, params) => {
    return axios({
        method: 'put',
        url: url,
        data: params
    });
}
 
//  DELETE 方法封装
export const deleteRequest = (url, params) => {
