vue-admin-template是基于vue-element-admin的一套后台管理系统基础模板(最少精简版),可作为模板进行二次开发。
GitHub地址:https://github.com/PanJiaChen/vue-admin-template
# 解压压缩包
# 进入目录
cd vue-admin-template-master
# 安装依赖
npm install
# 启动。执行后,浏览器自动弹出并访问http://localhost:9528/
npm run dev
创建LoginController
@RestController
@RequestMapping("/admin/vod/user")
@CrossOrigin
public class LoginController {
/**
* 登录
* @return
*/
@PostMapping("login")
public Result login() {
Map<String, Object> map = new HashMap<>();
map.put("token","admin");
return Result.ok(map);
}
/**
* 获取用户信息
* @return
*/
@GetMapping("info")
public Result info() {
Map<String, Object> map = new HashMap<>();
map.put("roles","[admin]");
map.put("name","admin");
map.put("avatar","https://oss.aliyuncs.com/aliyun_id_photo_bucket/default_handsome.jpg");
return Result.ok(map);
}
/**
* 退出
* @return
*/
@PostMapping("logout")
public Result logout(){
return Result.ok();
}
}
import request from '@/utils/request'
export function login(data) {
return request({
url: '/admin/vod/user/login',
method: 'post',
data
})
}
export function getInfo(token) {
return request({
url: '/admin/vod/user/info',
method: 'get',
params: { token }
})
}
export function logout() {
return request({
url: '/admin/vod/user/logout',
method: 'post'
})
}
(1)浏览器从一个域名的网页去请求另一个域名的资源时,域名、端口、协议任一不同,都是跨域 。前后端分离开发中,需要考虑ajax跨域的问题。
(2)跨域的本质:浏览器对Ajax请求的一种限制
(3)这里我们可以从服务端解决这个问题
在Controller类上添加注解
@CrossOrigin //跨域
修改 src/router/index.js 文件,重新定义constantRouterMap
**注意:**每个路由的name不能相同
export const constantRouterMap = [
{ path: '/login', component: () => import('@/views/login/index'), hidden: true },
{ path: '/404', component: () => import('@/views/404'), hidden: true },
// 首页
{
path: '/',
component: Layout,
redirect: '/dashboard',
name: 'Dashboard',
children: [{
path: 'dashboard',
component: () => import('@/views/dashboard/index'),
meta: { title: '硅谷课堂后台管理系统', icon: 'dashboard' }
}]
},
// 讲师管理
{
path: '/vod',
component: Layout,
redirect: '/vod/course/list',
name: 'Vod',
meta: {
title: '点播管理',
icon: 'el-icon-bank-card'
},
alwaysShow: true,
children: [
{
path: 'teacher/list',
name: 'TeacherList',
component: () => import('@/views/vod/teacher/list'),
meta: { title: '讲师列表' }
},
{
path: 'teacher/create',
name: 'TeacherCreate',
component: () => import('@/views/vod/teacher/form'),
meta: { title: '添加讲师' },
hidden: true
},
{
path: 'teacher/edit/:id',
name: 'TeacherEdit',
component: () => import('@/views/vod/teacher/form'),
meta: { title: '编辑讲师' },
hidden: true
}
]
},
{ path: '*', redirect: '/404', hidden: true }
]
