[JavaScript知识库]Vue3+ElementPlus+Koa2 全栈开发后台系统=＞菜单管理角色管理的增删改查功能⑨

本项目项目仓库地址:https://gitee.com/notlaughingzzm/vue3_elementPlus_admin.git

1.优化请求的Mock数据没设置导致bug问题

这两个模块的代码,使用的optionsApi,因为不涉及到比较复杂的功能.

 /**
  * 请求核心函数
  * @param {*} options请求配置
  */
function request(options) {
    options.method = options.method || 'get'
    if (options.method.toLowerCase() === 'get') {
        options.params = options.data
    }
    let isMock = config.mock; //防止我们多人开发的时候，有同事不屑mock:false,这样会导致还是去请求了Mock数据
    if(typeof options.mock != 'undefined'){
        isMock = options.mock;
    }

    if (config.env === 'prod') {
        service.defaults.baseURL = config.baseApi
    } else {
        service.defaults.baseURL = config.mock ? config.mockApi:config.baseApi
        service.defaults.baseURL = isMock ? config.mockApi:config.baseApi
    }
    
     return service(options)
}

2.填写api接口src/api/index.js

  menuSubmit(params) {
        return request({
            url: '/menu/operate',
            method: 'post',
            data: params,
            mock: true
        })
    }

3.添加静态路由src/router/index.js

{
                name: 'menu',
                path: '/system/menu',
                meta: {
                    title: '菜单管理'
                },
                component: () => import('./../views/Menu.vue')
            },

4.菜单管理页面构建src/views/Menu.vue

<template>
  <div class="user-manage">
    <div class="query-form">
      <el-form ref="form" :inline="true" :model="queryForm">
        <el-form-item label="菜单名称" prop="menuName">
          <el-input v-model="queryForm.menuName" placeholder="请输入菜单名称" />
        </el-form-item>
        <el-form-item label="菜单状态" prop="menuState">
          <el-select v-model="queryForm.menuState">
            <el-option :value="1" label="正常"></el-option>
            <el-option :value="2" label="停用"></el-option>
          </el-select>
        </el-form-item>
        <el-form-item>
          <el-button type="primary" @click="getMenuList">查询</el-button>
          <el-button @click="handleReset('form')">重置</el-button>
        </el-form-item>
      </el-form>
    </div>
    <div class="base-table">
      <div class="action">
        <el-button type="primary" @click="handleAdd(1)">新增</el-button>
      </div>
      <el-table
        :data="menuList"
        row-key="_id"
        :tree-props="{ children: 'children' }"
      >
        <el-table-column
          v-for="item in columns"
          :key="item.prop"
          :prop="item.prop"
          :label="item.label"
          :width="item.width"
          :formatter="item.formatter"
        >
        </el-table-column>

5.角色管理:页面构建,数据渲染src/views/Menu.vue

• 这里的api,把之前所有的allList改成List,因为之前的涉及到了分页,这里不需要分页

• src/views/User.vue

 // 初始化接口调用
    onMounted(() => {
      getUserList();
      getRoleList();
      getRoleAllList();
      getDeptList();
    });
     // 获取角色
    const getRoleList = async () => {
      let res = await proxy.$api.getRoleList();
    const getRoleAllList = async () => {
      let res = await proxy.$api.getRoleAllList();
      roleList.value = res;
    };
下面是return
     getRoleList,
     getRoleAllList,

  getRoleAllList(){
        return request({
            url:'/roles/allList',
            method:'get',
            mock:true
    }),
    getRoleList(){
        return request({
            url:'/roles/List',
            method:'get',
            data:{},
            mock:true
        })
    },

• 路由src/router/index.js

 {
                name: 'role',
                path: '/system/role',
                meta: {
                    title: '角色管理'
                },
                component: () => import('./../views/Role.vue')
            },

• 组建代码src/views/Role.vue

<template>

      <el-form ref="form" :inline="true" :model="queryForm">

6.角色管理:角色创建,编辑,删除完成

• src/api/index.js

• api和按钮

 roleOperate(params) {
        return request({
            url: '/roles/operate',
            method: 'post',
            data: params,
            mock: true
        })
    }
     <template #default="{row}">
            <el-button
              type="primary"
              size="mini"
              @click="handleEdit(row)"
              >编辑</el-button
            >
             <el-button
              type="danger"
              size="mini"
              @click="handleDel(scope.row._id)"
              @click="handleDel(row._id)"
              >删除</el-button
            >

• 弹框设计

<el-dialog title="角色创建" v-model="showModal">
      <el-form
        ref="dialogForm"
        :model="roleForm"
        label-width="100px"
        :rules="rules"
      >
        <el-form-item label="角色名称" prop="roleName">
          <el-input v-model="roleForm.roleName" placeholder="请输入角色名称" />
        </el-form-item>
        <el-form-item label="备注" prop="remark">
          <el-input 
          type="textarea" 
          :rows="2"
          v-model="roleForm.remark" 
          placeholder="请输入备注" />
        </el-form-item>
      </el-form>
      <template #footer>
        <span class="dialog-footer">
          <el-button @click="handleClose">取 消</el-button>
          <el-button type="primary" @click="handleSubmit">确 定</el-button>
        </span>
      </template>
    </el-dialog> 

• 数据层

export default {
  name: "role",
  data() {
    return {
      queryForm: {
        roleName: '',

      roleList: [],

        },
        {
          label: "备注",
          prop: "remark",
        },
        {
          label: "权限列表",

            return utils.formateDate(new Date(value));
          },

          },
        ],
      },
      action:''
    };
  },
  mounted() {
    this.getRoleList();
  },
  methods: {
    // 菜单列表初始化
    async getRoleList() {
      try {

    handleClose(){
