This error occurs because a page appears in your Vue router global navigation guard, jumps to a page and then redirects to another interface
router.beforeEach((to,from,next)=>{
if(to.matched.some(record => record.meta.requiresAuth)){
if(!store.state.user){
//Jump to the landing page
next({
name:'login',
query:{//Pass the query string parameter via url
redirect: to.fullPath//Tell the landing page the page that needs to be returned if the login is successful
}
})
}else{
next()
}
}else{
next()
}
next()
})
If such code appears in Vue router, this error will occur. The solution is not to use multi-layer if and else
