router.beforeEach((to,from,next)=>{
  //alert("还没有登录，请先登录！");
  //next();
  //console.log(to);

  //判断store.gettes.idLogin === false
  if(to.path == "/Login" || to.path == "/Register"){
    next();
  }else{
    alert('还没有登录，请先登录！');

    //判断store.gettes.idLogin === false
        // if(to.path == "/Login" || to.path == "/Register"){
        //   next();
        // }else{
