【vue】vue +element 搭建项目，mock模拟数据（纯干货）

1.安装mockjs依赖

(c)npm install mockjs --save-dev

2.安装axios(Ajax)

(c)npm install --save axios

3.项目目录

4.设计到的相关文件

fetch.js(封装axios)

import Qs from 'qs';
import axios from 'axios';
// 创建axios实例
const service = axios.create({
    baseURL: process.env.BASE_API, // api的base_url
    timeout: 5000,                  // 请求超时时间
    withCredentials: true,   //跨域
    transformRequest: [function (data) {
        data = Qs.stringify(data);
        return data
    }],
});

// request拦截器
service.interceptors.request.use(config => {
    config.headers['Accept'] = 'text/plain';
    config.headers['Content-Type'] = 'application/x-www-form-urlencoded';
    const defaultParams = {
        version: process.env.VERSION,
        platform: 'pcweb',
    };
    if (config.method == 'post') {
        config.data = {
            ...defaultParams,
            ...config.data
        }
    } else if (config.method == 'get') {
        config.params = {
            ...defaultParams,
            ...config.params
        }
    }
    return config;
}, error => {
    console.log(error); // for debug
    Promise.reject(error);
})

// respone拦截器
service.interceptors.response.use(
    response => {//其他一些（登陆过期等）请自行添加
        return response;
    },
    error => {
        return Promise.reject(error);
    });

export default service;

api/skill/index.js（接口定义）

import fetch from '@/utils/fetch';

export function departmentList(params) {
    return fetch({
        url: '/skill/list',
        method: 'get',
        params: params || {}
    });
}

mock/news.js（模拟数据）

import Mock from 'mockjs';
// 获取 mock.Random 对象
const Random = Mock.Random;
// mock一组数据
const produceNewsData = function () {
    let articles = [];
    for (let i = 0; i < 100; i++) {
        let newArticleObject = {
            title: Random.csentence(5, 30), //  Random.csentence( min, max )
            thumbnail_pic_s: Random.dataImage('300x250', 'mock的图片'), // Random.dataImage( size, text ) 生成一段随机的 Base64 图片编码
            author_name: Random.cname(), // Random.cname() 随机生成一个常见的中文姓名
            date: Random.date() + ' ' + Random.time() // Random.date()指示生成的日期字符串的格式,默认为yyyy-MM-dd；Random.time() 返回一个随机的时间字符串
        }
        articles.push(newArticleObject)
    }

    return {
        articles: articles
    }
}
export default {
    getexamUploder: () => produceNewsData(),
};

在main.js

import '@/mock/index.js';  // 使用mockjs模拟

mock/index.js

import Mock from 'mockjs';
import treeAPI from './news';

Mock.mock(/\/skill\/list/, 'get', treeAPI.getexamUploder);
export default Mock;

view/skill/tree.vue

import { departmentList } from '@/api/skill/index';//引入接口
getList(){
    let data = {
        pid: 0,
    }
    departmentList(data).then(response => {//接口调用
        console.log(response.data);
    });
},
