5.请求统一配置token

// 设置请求token
axios.interceptors.request.use(config => {
  // console.log(config)
  config.headers.Authorization = window.sessionStorage.getItem('token')
  // 在最后必须 return config
  return config
})

9.主页里的首页实现

1.编写主页

2.配置路由

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login'
import Home from '@/components/Home'
import Welcome from '@/components/Welcome'
Vue.use(Router)
const routerChildren = [
  {
    path: '/welcome',
    name: 'Welcome',
    component: Welcome
  }
]
const router = new Router({
  routes: [
    {
      path: "/",
      redirect: "/login"
    },
    {
      path: '/login',
      name: 'Login',
      component: Login
    }
    ,
    {
      path: '/home',
      name: 'Home',
      redirect: "/welcome",
      component: Home,
      children: routerChildren
    }
  ]
})
router.beforeEach((to, from, next) => {
  // to 将要访问的路径
  // from 从哪里跳转来的
  // next 放行
  // 判断是不是登录登录,登录路径直接放行
  if (to.path == '/login') {
    next()
    return
  }
  // 获取token,看是否有token,有token放行
  const token = window.sessionStorage.getItem("token")
  if (!token) {
    next('/login')
    return;
  }
  // 放行
  next();
})
export default router

View Code

3.设置路由占位

<!--主题-->
<el-main>
  <!-- 路由占位符 -->
  <router-view></router-view>
</el-main>

10.路由到各个子菜单

1.开启子菜单路由

2.index设置路由地址

3.编写各个路由组件

4.配置路由地址

import Vue from 'vue'
import Router from 'vue-router'
import Login from '@/components/Login'
import Home from '@/components/Home'
import Welcome from '@/components/Welcome'
import User from '@/components/user/User'
Vue.use(Router)
const routerChildren = [
  {
    path: '/welcome',
    name: 'Welcome',
    component: Welcome
  },
  {
    path: '/users',
    name: 'User',
    component: User
  }
]
const router = new Router({
  routes: [
    {
      path: "/",
      redirect: "/login"
    },
    {
      path: '/login',
      name: 'Login',
      component: Login
    }
    ,
    {
      path: '/home',
      name: 'Home',
      redirect: "/welcome",
      component: Home,
      children: routerChildren
    }
  ]
})
router.beforeEach((to, from, next) => {
  // to 将要访问的路径
  // from 从哪里跳转来的
  // next 放行
  // 判断是不是登录登录,登录路径直接放行
  if (to.path == '/login') {
    next()
    return
  }
  // 获取token,看是否有token,有token放行
  const token = window.sessionStorage.getItem("token")
  if (!token) {
    next('/login')
    return;
  }
  // 放行
  next();
})
export default router
