若依框架VUE前端界面，登录后默认跳转至动态路由第一路由（第一个子菜单）

一、登录后跳转第一路由界面

找到src目录下permission.js文件,作如下改动（如果存在路由参数，则带入）:

let path = '';
path = accessRoutes[0].path + '/' + accessRoutes[0].children[0].path //获取第一路由路径

if (accessRoutes[0].children[0].query !== undefined) { //如果当前路由存在路由参数，则带入
  let query = JSON.parse(accessRoutes[0].children[0].query);
  let temp = '';
  for (var val in query) {
    if (temp.length == 0) {
      temp = "?";
    } else {
      temp = temp + "&";
    }
    temp = temp + val + "=" + query[val];
  }
  path = path + temp;
}

if (from.path == '/login') {
  next({path, replace: true}) // hack方法 确保addRoutes已完成
} else {
  next({...to, replace: true}) // hack方法 确保addRoutes已完成
}

二、设置路由的首页路径，方便后续的获取

找到src目录下store\modules\permission.js文件,作如下改动:

1. 声明
   

,
    indexPage: '',

2. 赋值
   

  SET_INDEX_PAGE: (state, routes) => {
      state.indexPage = routes
    }

3. 获取默认路由的路径
   

getRouters().then(res => {
  const sdata = JSON.parse(JSON.stringify(res.data))
  const rdata = JSON.parse(JSON.stringify(res.data))

  let indexdata = res.data[0].path + "/" + res.data[0].children[0].path
  if (res.data[0].children[0].query !== undefined) { //如果当前路由存在路由参数，则带入
    let query = JSON.parse(res.data[0].children[0].query);
    let temp = '';
    for (var val in query) {
      if (temp.length == 0) {
        temp = "?";
      } else {
        temp = temp + "&";
      }
      temp = temp + val + "=" + query[val];
    }
    indexdata = indexdata + temp;
  }


  const sidebarRoutes = filterAsyncRouter(sdata)
  const rewriteRoutes = filterAsyncRouter(rdata, false, true)
  const asyncRoutes = filterDynamicRoutes(dynamicRoutes);
  rewriteRoutes.push({ path: '*', redirect: '/404', hidden: true })
  router.addRoutes(asyncRoutes);
  commit('SET_ROUTES', rewriteRoutes)
  commit('SET_SIDEBAR_ROUTERS', constantRoutes.concat(sidebarRoutes))
  commit('SET_DEFAULT_ROUTES', sidebarRoutes)
  commit('SET_TOPBAR_ROUTES', sidebarRoutes)
  commit('SET_INDEX_PAGE', indexdata)
  resolve(rewriteRoutes)
})

三、点击若依的logo跳转的页面的修改

找到src目录下src\layout\components\Sidebar\logo.vue文件,作如下改动:

<router-link v-if="collapse" key="collapse" class="sidebar-logo-link" :to="indexPage">
        <img v-if="logo" :src="logo" class="sidebar-logo" />
        <h1 v-else class="sidebar-title" :style="{ color: sideTheme === 'theme-dark' ? variables.logoTitleColor : variables.logoLightTitleColor }">{{ title }} </h1>
      </router-link>
      <router-link v-else key="expand" class="sidebar-logo-link" :to="indexPage">
        <img v-if="logo" :src="logo" class="sidebar-logo" />
        <h1 class="sidebar-title" :style="{ color: sideTheme === 'theme-dark' ? variables.logoTitleColor : variables.logoLightTitleColor }">{{ title }} </h1>
      </router-link>

import {mapState} from 'vuex'

...mapState({
 indexPage: state => state.permission.indexPage
})

四、关闭所有tagview后,会展示默认页面,设置禁止关闭首界面

找到src目录下src\layout\components\TagsView\index.vue文件,作如下改动:

import {mapState} from 'vuex'
...mapState({
  indexPage: state => state.permission.indexPage
})

      if (tag.fullPath == this.indexPage) {
        return true
      } else {
        return tag.meta && tag.meta.affix
      }

this.$router.push(this.indexPage)

五、个人中心关闭按钮后跳转的页面,防止点击关闭后页面空掉

找到src目录下src\plugns\tab.js文件,作如下改动:

 let indexPage = store.state.permission.indexPage;
    if (obj === undefined) {
      return store.dispatch('tagsView/delView', router.currentRoute).then(({ lastPath }) => {
        return router.push(lastPath || indexPage);
      });
    }

六、隐藏掉若依原本导航中的首页

找到src目录下src\components\BredCrumb\index.vue文件,作如下改动:

七、401和404页面返回首页,返回至默认首页

找到src目录下src\views\error\401.vue和404文件,作如下改动:

<ul class="list-unstyled">
          <li class="link-type">
            <router-link :to="indexPage">
              回首页
            </router-link>
          </li>
</ul>

import {mapState} from "vuex";
, computed: {
    ...mapState({
      indexPage: state => state.permission.indexPage
})

八、屏蔽首页

找到src目录下src\router\index.js文件,作如下改动:

九、重新登陆页面修改

找到src目录下src\utils\request.js文件,作如下改动:

let indexurl = this.$store.state.permission.indexPage
location.href = indexurl;
