用户管理模块

添加接口

在 http/moduls/user.js 中添加用户管理相关接口。

import axios from '../axios'

/*
* 用户管理模块
*/

// 保存
export const save = (params) => {
return axios({
url: '/user/save',
method: 'post',
params
})
}// 删除
export const del = (params) => {
return axios({
url: '/user/delete',
method: 'post',
params
})
}
// 分页查询
export const findPage = (params) => {
return axios({
url: '/user/findPage',
method: 'post',
params
})
}

模拟数据

在 mock/moduls/user.js 中添加用户管理相关mock接口。

/*
* 用户管理模块
*/

// 保存
export function save() {
return {
url: 'http://localhost:8080/user/save',
type: 'post',
data: {
"code": 200,
"msg": null,
"data": 1
}
}
}// 删除
export function del() {
return {
url: 'http://localhost:8080/user/delete',
type: 'post',
data: {
"code": 200,
"msg": null,
"data": 1
}
}
}
// 分页查询
export function findPage() {
return {
url: 'http://localhost:8080/user/findPage',
type: 'post',
data: findPageData
}
}

提取根路径

为了可以统一控制mock的开启与关闭，把mock的根路径提取出来。

而具体的Mock接口，把根路径移除，因为在生成Mock的时候会自动把根路径加上去。

用户界面

用户管理界面主要是用户信息的表格展示，并提供基础的增删改查功能。

User.vue

<template>
<div class="container" style="width:100%;">
<!--工具栏-->
<div class="toolbar" style="float:left; padding:18px;">
<el-form :inline="true" :model="filters" size="small">
<el-form-item>
<el-input v-model="filters.name" placeholder="用户名"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" v-on:click="findPage(null)">查询</el-button>
</el-form-item>
<el-form-item>
<kt-button label="新增" perms="sys:user:add" type="primary" @click="handleAdd" />
</el-form-item>
</el-form>
</div>
<!--表格内容栏-->
<kt-table permsEdit="sys:user:edit" permsDelete="sys:user:delete"
:data="pageResult" :columns="columns"
@findPage="findPage" @handleEdit="handleEdit" @handleDelete="handleDelete">
</kt-table>
<!--新增编辑界面-->
<el-dialog :title="operation?'新增':'编辑'" width="40%" :visible.sync="editDialogVisible" :close-on-click-modal="false">
<el-form :model="dataForm" label-width="80px" :rules="dataFormRules" ref="dataForm">
<el-form-item label="ID" prop="id">
<el-input v-model="dataForm.id" :disabled="true" auto-complete="off"></el-input>
</el-form-item>
<el-form-item label="用户名" prop="name">
<el-input v-model="dataForm.name" auto-complete="off"></el-input>
</el-form-item>
<el-form-item label="密码" prop="password">
<el-input v-model="dataForm.password" type="password" auto-complete="off"></el-input>
</el-form-item>
<el-form-item label="机构" prop="deptName">

:data="deptData"
:props="deptTreeProps"
:prop="dataForm.deptName"
:nodeKey="''+dataForm.deptId"

</el-form-item>
<el-form-item label="邮箱" prop="email">
<el-input v-model="dataForm.email" auto-complete="off"></el-input>
</el-form-item>
<el-form-item label="手机" prop="mobile">

<el-button type="primary" @click.native="editSubmit" :loading="editLoading">提交</el-button>

import KtButton from "@/views/Core/KtButton"
export default {
components:{
PopupTreeInput,
KtTable,
KtButton
},
data() {
return {
filters: {
name: ''
},
columns: [
{prop:"id", label:"ID", minWidth:40, sortable:"false"},
{prop:"name", label:"用户名", minWidth:120, sortable:"true"},
{prop:"deptName", label:"机构", minWidth:120, sortable:"true"},
{prop:"email", label:"邮箱", minWidth:120, sortable:"true"},

pageRequest: { pageNum: 1, pageSize: 8 },
pageResult: {},

operation: false, // true:新增, false:编辑

deptTreeProps: {

表格组件封装

为了可以实现表格的代码复用，封装表格组件。

src/views/Core/KtTable.vue

<template>
<div>
<!--表格栏-->
<el-table :data="data.content" stripe highlight-current-row @selection-change="selectionChange"
:v-loading="loading" :max-height="maxHeight" :size="size" :align="align" style="width:100%;" >
<el-table-column type="selection" width="40"></el-table-column>
<el-table-column v-for="column in columns"
:prop="column.prop" :label="column.label" :width="column.width" :min-width="column.minWidth"
:sortable="column.sortable" :fixed="column.fixed" :key="column.prop" :type="column.type">
</el-table-column>
<el-table-column label="操作" width="150" fixed="right">
<template slot-scope="scope">
<kt-button label="编辑" :perms="permsEdit" :size="size" @click="handleEdit(scope.$index, scope.row)" />
<kt-button label="删除" :perms="permsDelete" :size="size" type="danger" @click="handleDelete(scope.$index, scope.row)" />
</template>
</el-table-column>
</el-table>
<!--分页栏-->
<div class="toolbar" style="padding:10px;">
<kt-button label="批量删除" :perms="permsDelete" :size="size" type="danger" @click="handleBatchDelete()"
:disabled="this.selections.length===0" style="float:left;"/>
<el-pagination layout="total, prev, pager, next, jumper" @current-change="refreshPageRequest"
:current-page="pageRequest.pageNum" :page-size="pageRequest.pageSize" :total="data.totalSize" style="float:right;">
</el-pagination>
</div>
</div>
</template>

<script>
import KtButton from "@/views/Core/KtButton"
export default {
name: 'KtTable',
components:{
KtButton
},
props: {
columns: Array, // 表格列配置
data: Object, // 表格分页数据
permsEdit: String,  // 编辑权限标识
permsDelete: String,  // 删除权限标识
size: { // 尺寸样式
type: String,
default: 'mini'
},
align: {  // 文本对齐方式
type: String,
default: 'left'
},
maxHeight: {  // 表格最大高度
type: Number,
default: 420
}
},
data() {
return {
// 分页信息
pageRequest: {
pageNum: 1,
pageSize: 8
},
loading: false,  // 加载标识
selections: []  // 列表选中列
}
},
methods: {
// 分页查询
findPage: function () {
this.$emit('findPage', {pageRequest:this.pageRequest})
},
// 选择切换
selectionChange: function (selections) {
this.selections = selections
},
// 换页刷新
refreshPageRequest: function (pageNum) {
this.pageRequest.pageNum = pageNum
this.findPage()
},
// 编辑
handleEdit: function (index, row) {
this.$emit('handleEdit', {index:index, row:row})
},
// 删除
handleDelete: function (index, row) {
this.delete(row.id)
},
// 批量删除
handleBatchDelete: function () {
let ids = this.selections.map(item => item.id).toString()
this.delete(ids)
},
// 删除操作
delete: function (ids) {
this.$confirm('确认删除选中记录吗？', '提示', {
type: 'warning'
}).then(() => {
let params = []
let idArray = (ids+'').split(',')
for(var i=0; i<idArray.length; i++) {
params.push({'id':idArray[i]})
}
let callback = res => {
this.$message({message: '删除成功', type: 'success'})
this.findPage()
}
this.$emit('handleDelete', {params:params, callback:callback})
}).catch(() => {
})
}
},
mounted() {
this.refreshPageRequest(1)
}
}
</script>

<style scoped>

</style>

权限按钮封装

为了可以实现对表格数据进行新增、编辑、删除操作按钮的权限控制，封装权限按钮组件。

src/views/Core/KtButton.vue

<template>
<el-button :size="size" :type="type"
:loading="loading" :disabled="!hasPerms(perms)" @click="handleClick">
{{label}}
</el-button>
</template>

<script>
import { hasPermission } from '@/permission/index.js'
export default {
name: 'KtButton',
props: {
label: {
type: String,
default: 'Button'
},
size: {
type: String,
default: 'mini'
},
type: {
type: String,
default: null
},
loading: {
type: Boolean,
default: false
},
disabled: {
type: Boolean,
default: false
},
perms: {
type: String,
default: null
}
},
data() {
return {
}
},
methods: {
handleClick: function () {
this.$emit('click', {})
},
hasPerms: function (perms) {
return hasPermission(perms) & !this.disabled
}
},
mounted() {
}
}
</script>

<style scoped>

</style>
