角色管理模块
10.1 角色管理模块静态搭建
还是熟悉的组件:el-card、el-table 、el-pagination、el-form
<template>
<el-card>
<el-form :inline="true" class="form">
<el-form-item label="职位搜索">
<el-input placeholder="请你输入搜索职位关键字"></el-input>
</el-form-item>
<el-form-item>
<el-button type="primary" size="default">搜索</el-button>
<el-button type="primary" size="default">重置</el-button>
</el-form-item>
</el-form>
</el-card>
<el-card>
<el-button type="primary" size="default" icon="Plus">添加职位</el-button>
<el-table border style="margin: 10px 0px">
<el-table-column type="index" align="center" label="#"></el-table-column>
<el-table-column label="ID" align="center" prop="id"></el-table-column>
<el-table-column
label="职位名称"
align="center"
prop="roleName"
show-overflow-tooltip
></el-table-column>

<el-table-column label="操作" width="280px" align="center">
<!-- row:已有的职位对象 -->
<template #="{ row, $index }">
<el-button type="primary" size="small" icon="User">
分配权限
</el-button>
<el-button type="primary" size="small" icon="Edit">编辑</el-button>

</el-button>
</template>
</el-popconfirm>
</template>
</el-table-column>
</el-table>
</el-card>
<el-pagination
v-model:current-page="pageNo"
v-model:page-size="pageSize"
:page-sizes="[10, 20, 30, 40]"
:background="true"
layout="prev, pager, next, jumper,->,sizes,total"
:total="400"
@current-change="getHasRole"
@size-change="sizeChange"
/>
</template>
10.2 角色管理数据展示
10.2.1 API&&type
api:
//角色管理模块的的接口
import request from '@/utils/request'
import type { RoleResponseData, RoleData, MenuResponseData } from './type'
//枚举地址
enum API {
//获取全部的职位接口
ALLROLE_URL = '/admin/acl/role/',
}
//获取全部的角色
export const reqAllRoleList = (
page: number,
limit: number,
roleName: string,
) => {
return request.get<any, RoleResponseData>(
API.ALLROLE_URL + `${page}/${limit}/?roleName=${roleName}`,
)
}
type:
export interface ResponseData {
code: number
message: string
ok: boolean
}
//职位数据类型
export interface RoleData {
id?: number
createTime?: string
updateTime?: string
roleName: string
remark?: null
}
//全部职位的数组的ts类型
export type Records = RoleData[]
//全部职位数据的相应的ts类型
export interface RoleResponseData extends ResponseData {
data: {
records: Records
total: number
size: number
current: number
orders: []
optimizeCountSql: boolean
hitCount: boolean
countId: null
maxLimit: null
searchCount: boolean
pages: number
}
}
10.2.2 组件获取数据
//当前页码
let pageNo = ref<number>(1)
//一页展示几条数据
let pageSize = ref<number>(10)
//搜索职位关键字
let keyword = ref<string>('')
//组件挂载完毕
onMounted(() => {
//获取职位请求
getHasRole()
})
//获取全部用户信息的方法|分页器当前页码发生变化的回调
const getHasRole = async (pager = 1) => {
//修改当前页码
pageNo.value = pager
let result: RoleResponseData = await reqAllRoleList(
pageNo.value,
pageSize.value,
keyword.value,
)
if (result.code == 200) {
total.value = result.data.total
allRole.value = result.data.records
}
}
10.2.3 表格数据
<el-table border style="margin: 10px 0px" :data="allRole">
<el-table-column
type="index"
align="center"
label="#"
></el-table-column>
<el-table-column label="ID" align="center" prop="id"></el-table-column>
<el-table-column
label="职位名称"
align="center"
prop="roleName"
show-overflow-tooltip
></el-table-column>
<el-table-column
label="创建时间"
align="center"
show-overflow-tooltip
prop="createTime"
></el-table-column>
<el-table-column
label="更新时间"
align="center"
show-overflow-tooltip
prop="updateTime"
></el-table-column>
<el-table-column label="操作" width="280px" align="center">
<!-- row:已有的职位对象 -->
<template #="{ row, $index }">
<el-button type="primary" size="small" icon="User">
分配权限
</el-button>
<el-button type="primary" size="small" icon="Edit">编辑</el-button>
<el-popconfirm
:title="`你确定要删除${row.roleName}?`"
width="260px"
>
<template #reference>
<el-button type="primary" size="small" icon="Delete">
删除
</el-button>
</template>
</el-popconfirm>
</template>
</el-table-column>
</el-table>
10.2.4 分页器数据
同样的@current-change与@size-change函数回调。
<el-pagination
v-model:current-page="pageNo"
v-model:page-size="pageSize"
:page-sizes="[10, 20, 30, 40]"
:background="true"
layout="prev, pager, next, jumper,->,sizes,total"
:total="total"
@current-change="getHasRole"
@size-change="sizeChange"
/>
//下拉菜单的回调
const sizeChange = () => {
getHasRole()
}
10.2.5 搜索按钮
//搜索按钮的回调
const search = () => {
//再次发请求根据关键字
getHasRole()
keyword.value = ''
}
10.2.6 重置按钮
重置模块我在用户管理模块仔细解释过。
import useLayOutSettingStore from '@/store/modules/setting'
let settingStore = useLayOutSettingStore()
//重置按钮的回调
const reset = () => {
settingStore.refresh = !settingStore.refresh
}
10.3 添加&&修改职位
10.3.1 静态
<!-- 添加职位与更新已有职位的结构:对话框 -->
<el-dialog v-model="dialogVisite" title="添加职位">
<el-form>
<el-form-item label="职位名称">
<el-input placeholder="请你输入职位名称"></el-input>
</el-form-item>
</el-form>
<template #footer>
<el-button type="primary" size="default" @click="dialogVisite = false">
取消
</el-button>
<el-button type="primary" size="default">确定</el-button>
</template>
</el-dialog>
10.3.2 API&&TYPE
//新增岗位的接口地址
ADDROLE_URL = '/admin/acl/role/save',
//更新已有的职位
UPDATEROLE_URL = '/admin/acl/role/update',
//添加职位与更新已有职位接口
export const reqAddOrUpdateRole = (data: RoleData) => {
if (data.id) {
return request.put<any, any>(API.UPDATEROLE_URL, data)
} else {
return request.post<any, any>(API.ADDROLE_URL, data)
}
}
10.3.3 添加&&修改按钮绑定点击函数
10.3.4 添加&&修改按钮回调
//添加职位按钮的回调
const addRole = () => {
//对话框显示出来
dialogVisite.value = true
//清空数据
Object.assign(RoleParams, {
roleName: '',
id: 0,
})
//清空上一次表单校验错误结果
nextTick(() => {
form.value.clearValidate('roleName')
})
}
//更新已有的职位按钮的回调
const updateRole = (row: RoleData) => {
//显示出对话框
dialogVisite.value = true
//存储已有的职位----带有ID的
Object.assign(RoleParams, row)
//清空上一次表单校验错误结果
nextTick(() => {
form.value.clearValidate('roleName')
})
}
10.3.5 表单校验
:model:要校验的数据
:rules:校验的规则
ref:获取表单实例,方便后面调用validate函数来确保校验通过才放行
prop:绑定数据的属性
//自定义校验规则的回调
const validatorRoleName = (rule: any, value: any, callBack: any) => {
if (value.trim().length >= 2) {
callBack()
} else {
callBack(new Error('职位名称至少两位'))
}
}
//职位校验规则
const rules = {
roleName: [{ required: true, trigger: 'blur', validator: validatorRoleName }],
}
10.3.6 保存按钮的回调
//确定按钮的回调
const save = async () => {
//表单校验结果,结果通过在发请求、结果没有通过不应该在发生请求
await form.value.validate()
//添加职位|更新职位的请求
let result: any = await reqAddOrUpdateRole(RoleParams)
if (result.code == 200) {
//提示文字
ElMessage({
type: 'success',
message: RoleParams.id ? '更新成功' : '添加成功',
})
//对话框显示
dialogVisite.value = false
//再次获取全部的已有的职位
getHasRole(RoleParams.id ? pageNo.value : 1)
}
}
10.4 分配角色权限业务
10.4.1 API&&type(获取全部菜单)
//获取全部的菜单与按钮的数据
ALLPERMISSTION = '/admin/acl/permission/toAssign/',
//获取全部菜单与按钮权限数据
export const reqAllMenuList = (roleId: number) => {
return request.get<any, MenuResponseData>(API.ALLPERMISSTION + roleId)
}
注意:type这里MenuData与MenuList互相调用,适合这种树状的数据结构
//菜单与按钮数据的ts类型
export interface MenuData {
id: number
createTime: string
updateTime: string
pid: number
name: string
code: string
toCode: string
type: number
status: null
level: number
children?: MenuList
select: boolean
}
export type MenuList = MenuData[]
10.4.2 获取数据
分配权限按钮:
获取&&存储数据
//准备一个数组:数组用于存储勾选的节点的ID(四级的)
let selectArr = ref<number[]>([])
//已有的职位的数据
const setPermisstion = async (row: RoleData) => {
//抽屉显示出来
drawer.value = true
//收集当前要分类权限的职位的数据
Object.assign(RoleParams, row)
//根据职位获取权限的数据
let result: MenuResponseData = await reqAllMenuList(RoleParams.id as number)
if (result.code == 200) {
menuArr.value = result.data
// selectArr.value = filterSelectArr(menuArr.value, [])
}
}
10.4.3 展示数据
我们重点关注el-tree组件
data:展示的数据
show-checkbox:节点是否可被选择
node-key:每个树节点用来作为唯一标识的属性,整棵树应该是唯一的
default-expand-all:默认展开所有节点
default-checked-keys:默认勾选的节点的 key 的数组
props:属性: label:指定节点标签为节点对象的某个属性值 children:指定子树为节点对象的某个属性值
const defaultProps = {
//子树为节点对象的children
children: 'children',
//节点标签为节点对象的name属性
label: 'name',
}
10.4.4 展示数据(已分配的权限)
获取已分配权限的id,这里我们只需要收集最后一层的id即可,因为组件会自动更具最后一层的选择情况决定上层的选择状况。
注意:获取最后一层id的函数filterSelectArr使用了递归。
//分配权限按钮的回调
//已有的职位的数据
const setPermisstion = async (row: RoleData) => {
//抽屉显示出来
drawer.value = true
//收集当前要分类权限的职位的数据
Object.assign(RoleParams, row)
//根据职位获取权限的数据
let result: MenuResponseData = await reqAllMenuList(RoleParams.id as number)
if (result.code == 200) {
menuArr.value = result.data
selectArr.value = filterSelectArr(menuArr.value, [])
}
}
const filterSelectArr = (allData: any, initArr: any) => {
allData.forEach((item: any) => {
if (item.select && item.level == 4) {
initArr.push(item.id)
}
if (item.children && item.children.length > 0) {
filterSelectArr(item.children, initArr)
}
})
return initArr
}
10.4.5 API&&type(分配权限)
//给相应的职位分配权限
SETPERMISTION_URL = '/admin/acl/permission/doAssign/?',
//给相应的职位下发权限
export const reqSetPermisstion = (roleId: number, permissionId: number[]) => {
return request.post(
API.SETPERMISTION_URL + `roleId=${roleId}&permissionId=${permissionId}`,
)
}
10.4.6 收集用户分配的权限(每个权限的id)&&发请求
我们这里收集主要用到了2个方法:getCheckedKeys、getHalfCheckedKeys。它们会返回已选择以及半选择用户的id数组
//抽屉确定按钮的回调
const handler = async () => {
//职位的ID
const roleId = RoleParams.id as number
//选中节点的ID
let arr = tree.value.getCheckedKeys()
//半选的ID
let arr1 = tree.value.getHalfCheckedKeys()
let permissionId = arr.concat(arr1)
//下发权限
let result: any = await reqSetPermisstion(roleId, permissionId)
if (result.code == 200) {
//抽屉关闭
drawer.value = false
//提示信息
ElMessage({ type: 'success', message: '分配权限成功' })
//页面刷新
window.location.reload()
}
}
10.4.7删除业务
API&&TYPE
//删除已有的职位
export const reqRemoveRole = (roleId: number) => {
return request.delete<any, any>(API.REMOVEROLE_URL + roleId)
}
删除的回调
//删除已有的职位
const removeRole = async (id: number) => {
let result: any = await reqRemoveRole(id)
if (result.code == 200) {
//提示信息
ElMessage({ type: 'success', message: '删除成功' })
getHasRole(allRole.value.length > 1 ? pageNo.value : pageNo.value - 1)
}
}
