調用 js function

• index.js

import { post, fetch } from '@/until/http.js'
export default {
    //获取版本
    versions(data) {
        return post('/core/system-info', data)
    }, 
}	

• http.js

import axios from 'axios';
axios.defaults.timeout = 1000000; //设置超时时长
axios.defaults.baseURL = '';

/**
 * 封装post请求
 * @param url
 * @param data
 * @returns {Promise}
 */

export function post(url, params) {
    let data = {};
    data.method = url;
    data.params = params;
    data.lang = localStorage.getItem('local');
    return new Promise((resolve, reject) => {
        axios.post(url, params)
            .then(response => {
                resolve(response.data);
                // this.$Message.success('数据访问成功！');
            }, error => {
                reject(error);
                //this.$Message.error('数据访问错误！');
            })
    })
}
