1.1.什么是Mock.js 前后端分离开发开发过程当中经常会遇到以下几个尴尬的场景 老大接口文档还没输出我的好多活干不下去啊 后端小哥接口写好了没我要测试啊 前后端分离之后前端迫切需要一种机制不再需要依赖后端接口开发而今天的主角mockjs就可以做到这一点。 Mock.js是一个模拟数据的生成器用来帮助前端调试开发、进行前后端的原型分离以及用来提高自动化测试效率。 众所周知Mock.js因为两个重要的特性风靡前端:
数据类型丰富支持生成随机的文本、数字、布尔值、日期、邮箱、链接、图片、颜色等。拦截Ajax请求不需要修改既有代码就可以拦截Ajax请求返回模拟的响应数据。

1.2.安装与配置
1.2.1.安装mockjs
npm i mockjs -D 当我们安装完成后就会出现这个样子
1.2.2.引入mockjs 为了只在开发环境使用mock而打包到生产环境时自动不使用mock我们可以在config目录中的dev.env.js和prod.env.js做一个配置如下
dev.env.js
module.exports merge(prodEnv, {NODE_ENV: development,MOCK: true
})prod.env.js
module.exports {NODE_ENV: production,MOCK: false
}main.js
//开发环境下才会引入mockjs
process.env.MOCK require(/mock) 导入写好的mock-login.js文件和mock中的index.js文件
1.3.mockjs使用
1.3.1.定义测试数据文件 为每个*.vue定义单独的xxx-mock.js文件并在其中添加自定义的json数据还可以通过mockjs的模块生成随机数据信息动态测试ajax请求效果。 创建src/mock/json目录定义登录测试数据文件login-mock.js
login-mock.js
// const loginInfo {
// code: -1,
// message: 密码错误
// }//使用mockjs的模板生成随机数据
const loginInfo {code|-1-0: 0,message|3-10: msg
}
export default loginInfo;
1.3.2.mock拦截ajax请求 在src/mock目录下创建index.js定义拦截路由配置
index.js
import Mock from mockjs //引入mockjsnpm已安装
import action from /api/action //引入请求地址//全局设置设置所有ajax请求的超时时间模拟网络传输耗时
Mock.setup({// timeout: 400 //延时400s请求到数据timeout: 200 - 400 //延时200-400s请求到数据
})//引登陆的测试数据并添加至mockjs
import loginInfo from /mock/json/login-mock.js
let s1 action.getFullPath(SYSTEM_USER_DOLOGIN)
Mock.mock(s1, post, loginInfo)
// Mock.mock(s1, /post|get/i, loginInfo) 配置完成之后直接使用axios配置post或get请求模拟测试效果。 启动一下项目 npm run dev 点击登录出现下界面能够拿到模拟数据
1.3.3.数据模板定义规则额外知识要用的时候有用 请在使用的Vue组件中先导入Mock模块
import Mock from mockjs生成随机id值 使用Mock.Random 的方法在数据模板中称为『占位符』书写格式为 占位符(参数 [, 参数])
let uid1 Mock.Random.guid();
//使用占位符的方式
let uid2 Mock.mock(guid);
console.log(uid1);
console.log(uid2);string
let obj1 Mock.mock({star|1-5:★,//生成指定范围长度的字符串info:静态的字符串,//静态字符串name:cname//使用规定占位符cname随机生成中国人的名字
})
console.log(obj1);number 自增
1 是指在id的起始值每次调用1
// 1 是指在id的起始值每次调用1
let temp {id|1:1000001
}
console.log(Mock.mock(temp)); // 1000001
console.log(Mock.mock(temp)); // 1000002
console.log(Mock.mock(temp)); // 1000003
console.log(Mock.mock(temp)); // 1000004
console.log(Mock.mock(temp)); // 1000005
console.log(Mock.mock(temp)); // 1000006number随机生成
小数生成 |min-max.dmin(小数最小位数)-dmax(小数最大位数)
let obj2 Mock.mock({age|1-100:0,//随机生成0-100整数price|1-100.1-4:0,//随机生成整数部分1-100小数位数1-4位num|.2-4:0,//整数部分省略不写默认是0(js的默认规则)num2|100.3-3:0//整数部分保持100不变小数位数恒定3位数小数值随机生成
})
console.log(obj2);boolean值
let flag {flag1|0:true, //模板规则0数值是0时表示布尔值恒定是falseflag2|1:false,//值位1时boolean随机取值flag3|1-2:true
}
console.log(Mock.mock(flag));城市随机取值
let city Mock.mock({city1|2:{//数字2表示随机取2个值addr1:city,//占位符city表示随机生成城市addr2:city,//占位符city表示随机生成城市addr3:city,//占位符city表示随机生成城市addr4:city,//占位符city表示随机生成城市},city2|1-3:{//数字1-3表示随机取1-3个值addr1:city,//占位符city表示随机生成城市addr2:city,//占位符city表示随机生成城市addr3:city,//占位符city表示随机生成城市addr4:city,//占位符city表示随机生成城市}
})
console.log(city);枚举取值,从数组中随机取值
let gender Mock.mock({sex|1:[男,女,不知道],//数字1表示随机取数组中的一个值sex2|1:[男,女,不知道]//1表示循环一次取数组中的值
})
console.log(gender);正则表达式规则
let obj7 Mock.mock({user:{name:cname,},tel:/1[0-9]{10}/,//正则表达式可以使用插件email:/^[A-Za-z0-9\u4e00-\u9fa5][a-zA-Z0-9_-](\.[a-zA-Z0-9_-])$/,//函数表达式info:function(){//注意这里的this指向是数据模板对象所以可以在函数表达式里使用this来获取已有值return 我的手机号码是:${this.tel},我的邮箱是:${this.email},我的身份证号码是:${this.cardId}},// (8)路径规则中 表示启动关键字(注意前面不能有除了空格的任何其他字符)// / 表示在模板数据中的层级关系上下级message:我的名字是: /user/name ,我的手机号码是: /tel,我的邮箱是: /email,我的身份证号码是: /cardId
})
console.log(obj7);日期生成
let timer Mock.mock({day1:date,// date占位符表示随机生成mock默认格式的年月日day2:date(yyyy年MM月dd日),//date()可以传参自定义时间格式,time1:time,//time占位符可以随机生成mock格式的时分秒time2:time(HH时mm分ss秒SS毫秒),//同样可以在time()中传参数自定义格式daytime1:datetime(yyyy年MM月dd日 HH:mm:ss:SS),//daytime生成完整的时间nowTime:now
})
console.log(timer);图片生成
生成的是带参数的图片地址可以根据地址获取图片
let imgs Mock.mock({img:image(200x100, #894FC4, #FFF, png, !),img1:image(200x100, #aaaaa, #FFF, png, !),img2:image(200x100, #bbbbb, #FFF, png, !),// mock占位符调用时需要传递参数参数也可以是占位符img3:image(200x100, color, #FFF, png, !),//可以使用随机生成图片的网址但是注意统一网址的请求图片地址时如果不加参数那么浏览器默认地址一样的会使用浏览器的缓存那么所请求的图片只有一种一般加一个时间戳作为参数保持参数的唯一图片可以请求到不同的值img4:https://api.ixiaowai.cn/mcapi/mcapi.php?_time(T)
});
console.log(imgs);效果展示 打开emlementUI官网复制两个模板过来 贴到自己代码上 if (resp.data.code 0) {this.$message({message: resp.data.message,type: success});} else {this.$message.error(resp.data.message);}然后注意 要用es6中的箭头函数的写法不然如果嵌套在函数中的话这个this就不知道指向的是哪个this了指向的就不是vue的实例了

构建注册页面。 别忘了在router/index.js页面中导入Register.vue哦 使用this.$router.push({})实现路由跳转的几种方式
参数为字符串即路径名称
// 路径/home对应router目录下index.js中定义的path属性值
this.$router.push(/home);参数为对象
// 对应router目录下index.js中定义的path
this.$router.push({path:/home});参数为路由命名
// 对应router目录下index.js中定义的name
this.$router.push({name:Home});带参数
// 传递参数params里面放置的是我们要传递过去的参数
this.$router.push({name:Home,params:{user:david}});// 查询参数传递过去的内容会自动拼接变成/home?userdavid
this.$router.push({path:/home,query:{user:david}});query语法与params语法的区别 **写法的不同**query的语法用于path编写传参地址params的语法用于name编写传参地址**接收方式不同**query语法使用this.$route.params.nameparams语法使用this.$route.query.name**刷新页面参数消失问题**query在刷新页面时参数不会消失params再刷新页面时参数会消失**参数显示不同**query传递参数会显示在地址栏上相当于get请求params传递参数不会显示在地址栏上相当于post请求 3.总线组件通信

/script在TopNav中
scriptexport default {data(){return{collapsed:false,imgshow:require(/assets/img/show.png),imgsq:require(/assets/img/sq.png)}},methods:{doToggle(){this.collapsed!this.collapsed;//自定义收起事件this.$root.BUS.$emit(docollapsed,this.collapsed);}}}
/script4.退出功能 在methods中写上 exit(){this.$router.push({path:/})}
