简单概括就是，一个系统登录，跳转多个系统，其他系统不需要再登录，直接进入页面

 

登录的系统 

<template><div><div class="content"><div class="item" v-for="(item,index) in list" :key="index" @click="topath(item.url)">{{item.title}}</div></div></div>
</template><script>
export default {data () {return {list: [{title: '登录一',url: 'http://www.baidu.com/#/page/followUp'  // 跳转他的首页},{title: '登录一',url: 'http://www.baidu.com/#/page/followUp'  // 跳转他的首页},{title: '登录一',url: 'http://www.baidu.com/#/page/followUp'  // 跳转他的首页},{title: '登录一',url: 'http://www.baidu.com/#/welcome'  // 跳转他的首页}]}},methods: {topath (url) {// 拿到toekn,传给跳转的网址const Authorization = localStorage.getItem('Authorization')window.open(`${url}?Authorization=${Authorization}`, '_blank')}}
}
</script><style lang="less" scoped>
.content {display: flex;flex-wrap: wrap;justify-content: space-between;padding: 20px;.item {width: 345px;height: 140px;padding: 0 20px;background: #fff;margin: 0 24px 24px 0;display: flex;align-items: center;justify-content: center;border-radius: 6px;cursor: pointer;}
}
</style>

其他系统

// 在路由这里进行处理，获取Authorization，进行判断，存在，则直接进入
// 路由全局守卫
router.beforeEach((to, from, next) => {if (to.query.Authorization) {localStorage.setItem('Authorization', to.query.Authorization)}if (to.path === '/') {localStorage.clear()next()} else {if (localStorage.getItem('Authorization')) {next()} else {router.push('/')next()}}})
export default router
