Introduction to redirection features in Vue Router

Vue Router is the official routing manager of Vue.js, which allows us to configure routing in single-page applications. Manage access paths to each page. In addition to basic page routing functionality, Vue Router also provides some advanced features, one of which is redirection.

Redirection refers to the process of automatically navigating users from one URL to another. Vue Router provides two ways to implement redirection, one is to configure the redirect attribute of the route, and the other is to implement redirection through programmatic navigation.

1. Redirect by configuring the redirect attribute

In the routing configuration of Vue Router, we can define the redirect of an object Attributes to implement redirection. When a user accesses a certain path, routing will automatically redirect them to the specified path.

Here is a simple example:

import Vue from 'vue'
import Router from 'vue-router'

Vue.use(Router)

export default new Router({
  routes: [
    {
      path: '/',
      redirect: '/home'
    },
    {
      path: '/home',
      component: Home
    },
    {
      path: '/about',
      component: About
    }
  ]
})

In the above code, when the user accesses the root path /, the route will redirect them to /home path to display the Home component.

2. Redirection through programmatic navigation

In addition to redirection through configuration, Vue Router also provides programmatic navigation to implement redirection. By calling the $router.push() method in the code, we can perform page navigation in the component and redirect during the navigation process.

The following is a sample code:

export default {
  methods: {
    goToHome() {
      this.$router.push('/home')
    },
    goToAbout() {
      this.$router.push('/about')
    },
    redirectToHome() {
      this.$router.replace('/home')
    }
  }
}

In the above code, the goToHome() and goToAbout() methods respectively navigate the user to /home and /about paths. The redirectToHome() method redirects the user to the /home path by calling the $router.replace() method.

Through the above two methods, we can easily implement the redirection function. Whether when configuring routing or performing programmatic navigation in components, Vue Router provides us with powerful redirection features, allowing us to more flexibly control the page jump process.

Summary:

Redirection is an important feature of Vue Router. It can navigate users from one URL to another URL, thereby realizing automatic page jump. By configuring the route's redirect attribute or using programmatic navigation, we can easily implement the redirection function. The redirection feature of Vue Router provides us with a better user experience and more flexible page jump control when building single-page applications.
