37 ，导航守卫 ，token过期时间

router--index.js

router.beforeEach((to,from,next)=>{
    
    let nextRoute = ['Payment','Cart','Path','Order','pathIndex','path-list'];
    //是否是登录中
    let userInfo = JSON.parse( localStorage.getItem('teaUserInfo')  );
    
    //当前进入的页面，是不是需要验证哪些页面
    if(  nextRoute.indexOf( to.name ) >= 0  ){
        if( !userInfo ){
            router.push('/login');
        }
    }
    
    next();
})

路由版本问题

解决

const originalPush = VueRouter.prototype.push
const originalReplace = VueRouter.prototype.replace
// push
VueRouter.prototype.push = function push (location, onResolve, onReject) {
  if (onResolve || onReject) return originalPush.call(this, location, onResolve, onReject)
  return originalPush.call(this, location).catch(err => err)
}
// replace
VueRouter.prototype.replace = function push (location, onResolve, onReject) {
  if (onResolve || onReject) return originalReplace.call(this, location, onResolve, onReject)
  return originalReplace.call(this, location).catch(err => err)
}

 token 

后台 db---userSql.js  

token设置成60s

  //生成token
    let token = jwt.sign(payload, secret, {
      expiresIn: 60,
    });

index.js

function getTimeToken(exp) {
  let getTime = parseInt(new Date().getTime() / 1000);

  if (getTime - exp > 60) {
    return true;
  }
}
