vue中如何使用mockjs摸拟接口的各种数据

mockjs的作用

• 生成模拟数据
• 模拟 ajax 请求，返回模拟数据
• 基于 html 模板生成模拟数据（后续更新）
• 帮助编写单元测试（后续更新）

vue 中使用 mock

• 有两种使用方式，一种是仅编写数据来调用，第二种是编写 服务+数据模拟真实接口（可在network查看）
• mock对象api用例查看（推荐只看这个就可以）

第一种方式，编写mock

• 可以写完整action url：http://localhost/login
• 同一域下，也可以只写api形式：/login
• 使用 mock.mock 可以编写多个接口数据

import mock from 'mockjs'; //es6语法引入mock模块

mock.mock('/login', { //输出数据
    'name': '@name', //随机生成姓名
    //还可以自定义其他数据
});
mock.mock('/list', { //输出数据
    'age|10-20': 10
    //还可以自定义其他数据
});

两种数据调用方式

1.使用 mock.mock 直接编写

mock.mock('@date("yyyy-mm-dd")');//"1984-06-12"

2.使用 随机函数 random 编写

var random = mock.random;
random.date('yyyy-mm-dd');//"2018-08-16"

第一种方式，调用mock

• 注意，将 mock.js 直接导入即可

import "../mock/mock.js";
axios.post("/login").then(response => {
    if (response.data) {
      this.jumptokpi();
    }
});

第二种方式，编写server

使用 express 提供服务

• 首先需要安装几个依赖：express、babel-cli（支持es6编写服务）
• 通过 babel-node mockservice.js 命令启动服务
• 注意，babel-node命令不能支持 import 写法，使用 require 即可。如要用 import 请自行解决

npm i --save-dev express
npm install --save-dev babel-cli
babel-node mockservice.js

跨域设置

• 假设 express 服务使用 8090 端口，而 vue 开发一般启动 8080，则必定跨域，需在 server 端进行设置

app.use(function (req, res, next) {
    res.header("access-control-allow-origin", "*");
    res.header('access-control-allow-methods', 'put, get, post, delete, options');
    res.header("access-control-allow-headers", "x-requested-with");
    res.header('access-control-allow-headers', 'content-type');
    next();
});

在chrome network下可查看到接口调用

//请求接口地址
http://localhost:8090/list

//数据返回
{
    "status":200,
    "list":[
        {
            "name":"john brown",
            "age":50,
            "address":"东北",
            "date":"2017-08-17"
        },
        {
            "name":"jim green",
            "age":25,
            "address":"东北",
            "date":"2017-08-17"
        },
        {
            "name":"joe black",
            "age":35,
            "address":"东北",
            "date":"2017-08-17"
        }
    ]
}

完整的 mockservice.js 如下

// import express from "express"
// import mock from "mockjs"
const express = require('express');   //引入express
const mock = require('mockjs');       //引入mock

let app = express();
const random = mock.random;

app.use(function (req, res, next) {
    res.header("access-control-allow-origin", "*");
    res.header('access-control-allow-methods', 'put, get, post, delete, options');
    res.header("access-control-allow-headers", "x-requested-with");
    res.header('access-control-allow-headers', 'content-type');
    next();
});

app.use('/list', function (req, res) {
    res.json(mock.mock({
        'status': 200,
        'list|10': [
            {
                "name|+1": ["john brown", "jim green", "joe black", "jon snow"],
                "age|18-70": 70,
                "address": random.region(),
                "date": random.date()
            }
        ]
    }))
})

app.listen('8090', () => {
    console.log('监听端口 8090')
})
