基于Vue和Node.js的电商后台管理系统

// 创建并切换登录分支
git checkout -b login

// login分支合并到主分支
// 1.切换到master分支
git checkout master
// 2.合并分支到master
git merge login

// 将本地login子分支推送到github
git push -u origin login

//为路由对象,添加beforeEach导航守卫
router.beforeEach((to,from,next) => { 
   
    //如果用户访问的登录页,直接放行
    if (to.path === 'login') return next()
    //从sessionStorage中获取到保存的token值
    const tokenStr = window.sessionStorage.getItem('token')
    //如果么有token,强制跳转到登录页
    if(!tokenStr) return next('/login')
    next()
})

// axios请求拦截
axios.interceptors.request.use(config => { 
   
    // 为请求头对象,添加token验证的Authorization字段
    config.headers.Authorization = window.sessionStorage.getItem('token')
    return config
})
