How to jump to the previous page in vue
This article shares with you a function of Vue to implement a page jump to the previous page after login. Friends who need this convenience can learn from it.
In development, we often encounter such needs. The user needs to directly click a link to enter a page. After the user clicks the link, a 401 interception will be triggered and returned to the login interface. After logging in, he will jump to the linked page. Instead of the homepage, how should we solve this problem?
Let’s first talk about a few APIs we need to use:
1.router.currentRoute: The current routing information object, we can get the parsed URL through router.currentRoute.fullPath, Contains the full path of query parameters and hash. If the route of the page to be accessed has a name, the name of the current route can be obtained through router.currentRoute.name.
2.router.replace: The function is the same as router.push, but it does not add new records to the history, but replaces the current history record.
Since everyone’s code is written differently, I will not include my specific implementation code, but briefly introduce the idea:
1. After the user clicks on the link, the target to jump to routing page, then trigger the 401 interceptor and return to the login page:
//401拦截
if（status == "401"）{
router.push("/login")
}2. We can save the target link in the url when 401 is intercepted:
if (status == 401) {
//判断当前的路由是否是目标路由
if(router.currentRoute.name == "target"){
//跳转回login路由，并把目标路由的url路径保存在login的query中
router.replace({
name:"login",
query: {redirect: router.currentRoute.fullPath}
})
}else{
/* 普通401拦截直接返回到登录页面 */
router.push('/login');
}
}3. After clicking login Use the query saved on the url to jump directly back to the target page
router.push({path:decodeURIComponent(url)});The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
