vue 对axios get pust put delete 封装

 

 axios.js

import axios from 'axios';
import Qs from 'qs';
import {Message} from 'element-ui';


axios.defaults.baseURL = "/api";
// 设置请求超时时间
axios.defaults.timeout = 30000;

// 设置post请求头
axios.defaults.headers.post['Content-Type'] = 'application/json;charset=UTF-8';

// 请求拦截
axios.interceptors.request.use(config => {
    // 在发送请求之前做些什么 验证token之类的

    return config;
}, error => {
    // 对请求错误做些什么

    Message.error({message: '请求超时!'})
    return Promise.error(error);
})

// 响应拦截
axios.interceptors.response.use(response => {
    // 对响应数据做点什么

    return response;
}, error => {
    // 对响应错误做点什么

    return Promise.reject(error);
});


// 封装get方法和post方法
