在vuex中管理mock数据

关于vuex的简单理解在这篇文章中已经提过了,如何在vuex中管理mock数据呢。

Electron-vue实战(三)— 如何在Vuex中管理Mock数据

这是效果界面,所用的数据是mock模拟所得,使用vuexstore存储管理模拟数据。

Electron-vue实战(三)— 如何在Vuex中管理Mock数据

这是我的store目录结构,分成几个模块,以其中planList模块为例进行讲解。

1.配置Vuex

modules文件夹中新建一个文件planList.js,然后在modules/index.js中导入

import planList from './planList'
const files = require.context('.', false, /\.js$/)
const modules = {
planList // 模块名
} files.keys().forEach(key => {
if (key === './index.js') return
modules[key.replace(/(\.\/|\.js)/g, '')] = files(key).default
}) export default modules

store/index.js

import Vue from 'vue'
import Vuex from 'vuex'
import modules from './modules'
// const strict = process.env.NODE_ENV !== 'production'
const strict = false // 当为严格模式下时,一切的更改状态的动作都只能在mutation中进行,否则报错
Vue.use(Vuex) export default new Vuex.Store({
modules,
strict: strict
})

然后在主文件main.js中引用:

import store from './store'

new Vue({
components: {
App
},
router,
store,
template: '<App/>'
}).$mount('#app')

2.Mock数据

Electron-vue实战(三)— 如何在Vuex中管理Mock数据

关于如何mock数据可以去官网查看,这里只粘贴部分代码,不再多说

// data/planList.js
import Mock from 'mockjs'
const Random = Mock.Random
const List = []
const count = 300 for (let i = 0; i < count; i++) {
List.push(Mock.mock({
id: Random.integer(6000, 6999), // 编号
airline: Random.string('upper', 2), // 航空公司
flightNum: Random.string('upper', 2) + Random.integer(1000, 9999), // 航班号
'cityCode|1': ['京', '津', '冀', '晋', '内蒙古', '辽', '吉', '黑', '沪', '苏', '浙', '皖', '闽', '赣', '鲁', '豫', '鄂', '湘', '粤', '桂', '琼', '川', '贵', '云', '渝', '藏', '陕', '甘', '青', '宁', '新'], // 城市简码 }))
} export { List }

然后拦截数据,这里使用的是axios-mock-adapter,可以使用npm install axios-mock-adapter -D进行安装,然后在mock.js中引入:

import axios from 'axios'
import MockAdapter from 'axios-mock-adapter'
import { List } from './data/planList' let _planList = List export default {
bootstrap () {
let mock = new MockAdapter(axios) // mock success request
mock.onGet('/success').reply(200, {
msg: 'success'
}) // mock error request
mock.onGet('/error').reply(500, {
msg: 'failure'
}) // 获取列表(分页)
mock.onGet('/flight/getListPage').reply(config => {
let { page, pageSize, id } = config.params
let mockList = _planList.filter(item => {
if (id && item.name.indexOf(id) === -1) return false
return true
})
let total = mockList.length
mockList = mockList.filter((u, index) => index < pageSize * page && index >= pageSize * (page - 1))
return new Promise((resolve, reject) => {
setTimeout(() => {
resolve([200, {
total: total,
list: mockList
}])
}, 1000)
})
})
}
}

3.封装axios

新建一个api文件夹,建立request.js文件,封装请求。

Electron-vue实战(三)— 如何在Vuex中管理Mock数据

import axios from 'axios'
import { Message } from 'element-ui'
import store from '../store' axios.defaults.headers.post['Content-Type'] = 'application/x-www-form-urlencoded'
// 创建axios实例
const instance = axios.create({
baseURL: process.env.BASE_API, // api的base_url
timeout: 3000 // 请求超时时间
})
// request拦截器
instance.interceptors.request.use(config => {
if (store.getters.token) {
config.headers['X-Token'] = store.getters.token// 让每个请求携带自定义token 请根据实际情况自行修改
}
return config
}, error => {
console.log(error) // for debug
Promise.reject(error)
}) // 响应拦截器
instance.interceptors.response.use(
response => {
/**
* code不是200时抛错 可结合自己业务进行修改
*/
const res = response.data
if (res.code !== 200) {
Message({
message: res.message,
type: 'error',
duration: 5 * 1000
}) return Promise.reject('error')
} else {
return response.data
}
},
error => {
console.log('err' + error)// for debug
Message({
message: error.message,
type: 'error',
duration: 5 * 1000
})
return Promise.reject(error)
}
) export default function (method, url, data = null) {
method = method.toLowerCase()
if (method === 'post') {
return instance.post(url, data)
} else if (method === 'get') {
return instance.get(url, {
params: data
})
} else if (method === 'delete') {
return instance.delete(url, {
params: data
})
} else if (method === 'put') {
return instance.put(url, data)
} else {
console.error('未知的method' + method)
return false
}
}

然后在api.js中封装接口:

// import request from './request'
import axios from 'axios' let baseURL = ''
// 获取计划列表
export const getPlanList = params => {
return axios.get(`${baseURL}/flight/planList`, { params: params })
} // 获取列表分页
export const getPlanListPage = params => {
return axios.get(`${baseURL}/flight/getListPage`, { params: params })
}
// index.js中导入
import * as api from './api' export default api

4.vuex中管理mock数据

modules/planList.js中调用接口,将获取到的mock数据保存在本地state中,然后组件中调用相应的数据进行渲染显示即可:

import { getPlanListPage } from '@/api/api' // 接口
import { GET_PLAN_LIST } from './mutation-type' // mutation类型常量化 在mutation-type.js中进行配置即可,也可以不用这样写,详情可见官方文档 export default {
namespaced: true,// 启动命名空间
state: {// 声明本地管理的状态
list: {
tableData: [],
total: 0,
currentPage: 1,
pageSize: 20,
listLoading: false,
id: ''
}
},
getters: {
list: state => state.list
},
mutations: {
[GET_PLAN_LIST]: state => {
let para = {
page: state.list.currentPage,
pageSize: state.list.pageSize,
id: state.list.id
}
state.list.listLoading = true
getPlanListPage(para)
.then(res => {
console.log(res.data)
// 将获取的数据保存在state中全局使用
state.list.total = res.data.total
state.list.tableData = res.data.list
state.list.listLoading = false
})
.catch(error => {
console.log(error)
})
}
},
actions: { // 异步响应
getPlanList: context => {
context.commit('GET_PLAN_LIST')
}
}
}

5.组件中获取状态

import { mapGetters, mapActions, mapMutations } from 'vuex'
mounted () {
this.getPlanList() // 挂载
},
computed: {
...mapGetters('planList', ['list'])
},
methods: {
...mapActions('planList', ['getPlanList']),
...mapMutations('planList', ['GET_PLAN_LIST']),
// 显示每页多少条数据
handleSizeChange (val) {
this.list.pageSize = val
this.list.currentPage = 1
this.GET_PLAN_LIST()
},
// 当前页
handleCurrentChange (val) {
this.list.currentPage = val
this.GET_PLAN_LIST()
}
}
<!-- 这里只粘贴了表格的代码 从list中调用数据-->
