前言

借助于mockjs和fetch-mock来实现对fetch的mock，使用fetch-mock来拦截fetch请求，使用mockjs来模拟数据。

内容

从安装mock和fetch-mock到封装，一条龙服务，让你不再迷茫；

安装依赖

$ pnpm i -D mockjs
$ pnpm i -D fetch-mock

封装mock

在src目录下创建mock目录，结构如下：

src/mock
└── index.js

封装内容如下：

import Mock from 'mockjs';
import fetchMock from 'fetch-mock';

const Random = Mock.Random;

// 设备总览
function getAudienceData() {
    const data = Mock.mock({
        msg: '操作成功',

        data: {
