10个人中心功能的开发

逻辑

个人资料查看权限：

管理员(ADMIN)查看 /person 页面
教师(TEACHER)查看 /tPerson 页面
学生(STUDENT)查看 /sPerson 页面
每个角色只能看到自己的个人资料页面，路径不同但功能类似

用户管理权限：

只有管理员(ADMIN)能看到用户管理菜单（包含管理员/教师/学生信息）
教师和学生完全看不到这个菜单（通过 v-if=”data.user.role === ‘ADMIN’” 控制）

Manager.vue

<!-- 在是什么角色的时候看到什么角色的个人资料-->
<el-menu-item v-if="data.user.role === 'ADMIN'" index="/person"><el-icon><User /></el-icon><span>个人资料</span></el-menu-item>
          <el-menu-item v-if="data.user.role === 'TEACHER'" index="/tPerson"><el-icon><User /></el-icon><span>个人资料</span></el-menu-item>
          <el-menu-item v-if="data.user.role === 'STUDENT'" index="/sPerson"><el-icon><User /></el-icon><span>个人资料</span></el-menu-item>

<!-- 仅管理员可以看到用户管理，教师和学生都看不到-->
 <el-sub-menu index="2" v-if = "data.user.role = 'ADMIN'">
            <template #title>
              <el-icon><Memo /></el-icon>
              <span>用户管理</span>
            </template>
            <el-menu-item index="/admin">
              <el-icon><User /></el-icon>
              <span>管理员信息</span>
            </el-menu-item>
            <el-menu-item index="/teacher">
              <el-icon><Avatar /></el-icon>
              <span>教师信息</span>
            </el-menu-item>
            <el-menu-item index="/student">
              <el-icon><Avatar /></el-icon>
              <span>学生信息</span>
            </el-menu-item>
          </el-sub-menu>

{ path: 'person', component: () => import('@/views/manager/Person.vue')},
{ path: 'tPerson', component: () => import('@/views/manager/TPerson.vue')},
{ path: 'sPerson', component: () => import('@/views/manager/SPerson.vue')},

Cannot read properties of undefined (reading ‘sex’)
遇到这种报错，基本上是遇到了 xxx.sex，比如form.sex，如果这个xxx（form)是undefined，那么就会出现这样的报错。

新建TPerson.vue
