SPA项目开发之首页导航+左侧菜单

内容:
1、mock.js模拟响应ajax请求
2、通过js代码完成路由的跳转
3、后台主界面的搭建
4、退出功能
5、左侧树收缩功能(vue总线的概念)

1. 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:
1. 老大,接口文档还没输出,我的好多活干不下去啊!
2. 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。

更多内容,可以云Mockjs官方查看“http://mockjs.com/”


注1:easy-mock,一个在线模拟后台的数据平台

2. Mock.js使用步骤
2.1 安装mockjs依赖
npm install mockjs -D #只在开发环境使用

2.2 引入
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env中做一个配置
(1)dev.env
module.exports = merge(prodEnv, {
NODE_ENV: '"development"',
MOCK: 'true'
})


(2)prod.env
module.exports = {
NODE_ENV: '"production"',
MOCK: 'false'
}

 

(3)main.js
//开发环境下才会引入mockjs
process.env.MOCK && require('@/mock')

 

注1:import是ES6标准中的模块化解决方案,require是node中遵循CommonJS规范的模块化解决方案
后者支持动态引入,也就是require(${path}/xx.js)

2.3 目录和文件创建
在src目录下创建mock目录,定义mock主文件index.js,并在该文件中定义拦截路由配置,
/src/mock/index.js

import Mock from 'mockjs' //引入mockjs,npm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)

 


导入公共模块及mockjs全局设置
import Mock from 'mockjs' //引入mockjs,npm已安装
import action from '@/api/action' //引入封装的请求地址

//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
})

注1:index.js文件的作用很显然,就是将分散的xxx-mock文件集合起来.后面再添加新的mock文件,都需要在这里引入


2.4 为每个*.vue定义单独的xxx-mock.js文件
/src/mock/json/login-mock.js

注1:可以添加自定义的json数据
注2:还可以通过mockjs的模板生成随机数据


2.5 在index.js中导入xxx-mock.js,并添加拦截路由配置
import loginInfo from '@/mock/json/login-mock.js'
Mock.mock(url, "post", {...})


注1:如何同时拦截get/post请求,并对get和post请求大小写不敏感呢?那就请使用正则表达式吧
Mock.mock(url, /post|get/i,{})

注2:Mockjs如何拦截带参数的GET请求
在实践过程中,发现mockjs对GET请求的支持并不是很友好。
例如:使用 Mock.mock("/user/getUserInfo", "get", mockData) 的时候,它只会拦截url等于 /user/getUserInfo 的请求,
而对于带参数的请求,如/user/getUserInfo?id=12,因为不等于 /user/getUserInfo 就拦截不到。
解决方案:通过正则表达式实现
Mock.mock(RegExp(url + ".*"), /post|get/i, {...});

注3:定义拦截路由配置最简单的方式就是使用POST请求,并且不在URL中添加参数(推荐)

注4:还可以通过控制台将将请求和参数都打印出来,以便调试
Mock.mock(url, "get", (options) =>{
// 最佳实践,
console.debug(url, options);
return Mock.mock(mockUserInfo);
});

2.6 之后ajax请求便会被mock拦截了


## 登陆与注册页面的跳转
3. 使用this.$router.push({})实现路由跳转
3.1 字符串
this.$router.push('/home/first')

3.2 对象
this.$router.push({ path: '/home/first' })

3.3 命名的路由
this.$router.push({ name: 'home', params: { userId: wise }})

3.4 this.$router.push、replace、go的区别
this.$router.push()
跳转到不同的url,但这个方法会向history栈添加一个记录,点击后退会返回到上一个页面

this.$router.replace()
同样是跳转到指定的url,但是这个方法不会向history里面添加新的记录,点击返回,会跳转到上上一个页面。上一个记录是不存在的。

this.$router.go(n)
相对于当前页面向前或向后跳转多少个页面,类似 window.history.go(n)。n可为正数可为负数。负数返回上一个页面

5. vue Bus总线


5.1 将一个空的Vue实例放到根组件下,所有的子组件都能调用
main.js
new Vue({
el: '#app',
router,
components: {
App
},
template: '<App/>',
data: {
//自定义的事件总线对象,用于父子组件的通信
Bus: new Vue()
}
})

5.2 在A组件触发事件
this.$root.Bus.$emit("事件名", 参数1, 参数2, ...);

注1:关键点-->this.$root
以前父子组件间触发事件是:this.$emit("事件名", 参数1, 参数2, ...);

5.3 在B组件监听事件
this.$root.Bus.$on("事件名", 回调函数);

 

注1:有时候会发生事件只被emit触发了一次,但是回调函数却被执行了多次的现象。这种现象往往发生在页面跳转退出后重新进入的时候。
产生原因:
this.$root.Bus.$on实际是向Bus容器中添加一个事件监听器,当页面跳转时,原来的vue组件被注销,但是原来vue组件向Bus容器中添加的事件监听器并不会被移除。
因此,当下次进入这个vue组件对应的页面时,执行到this.$root.Bus.$on时,又会向Bus容器中添加一个重复的事件监听器,以此类推,
导致Bus容器中有很多个一模一样的事件监听器,从而导致事件只被触发一次,但是回调函数被执行多次的现象。
解决方案:
在vue组件的beforeDetory钩子函数中将本vue组件往Bus容器中添加的事件监听器全部手动移除。
//在vue对象的methods域中定义个函数专门移除事件监听器
offxxxListener: function () {
this.$root.Bus.off("事件名");
this.$root.Bus.off("事件名");
this.$root.Bus.off("事件名");
},

//在vue对象的beforeDestroy钩子中调用以上函数
beforeDestroy() {
this.offxxxListener();
},
注2::not(selector) 选择器匹配每个元素是不是指定的元素/选择器。

详情见资料“04 ES6新特性:使用export和import实现模块化 - 方方和圆圆 - 博客园.mht”


附录二:easy-mock
一个在线模拟后台的数据平台,通过官网注册账户之后,你就可以生成一个在线的API接口,然后通过ajax或者axios就可以访问这个接口了
如果前端开发人员很多,存在跨地区合作,交流困难,后端接口需要频繁修改的话.这种写法并不适合!
这时候推荐使用easy-mock.部署到本地内网后,就可以和其他前端后端小伙伴愉快地 共同维护mock数据和接口.


附录三:
collaps:折叠,collapsed,折叠的过去分词
Toggle:切换开关
