Let's talk about how to hide Vue routing parameters

Vue is a popular JavaScript framework widely used for front-end development. Vue Router is its official routing management tool, which allows developers to easily implement the routing function of SPA (Single Page Application). In Vue Router, we usually use routing parameters to dynamically switch pages. However, in some specific scenarios, we may need to hide and encrypt routing parameters. This article will introduce you to how to hide routing parameters in Vue.

1. Basic use of routing parameters

In Vue Router, routing parameters are defined by using a colon prefix, for example:

{ path: '/user/:id', component: User }

In the above code, we define A routing parameter named "id", which can dynamically display the corresponding user information when the user accesses "/user/1". In the component, we can access the value of the current routing parameter through $route.params, for example:

const User = {
  template: '<div>{{ $route.params.id }}</div>'
}

2. Hiding routing parameters

In actual development, sometimes we want to Routing parameters are hidden, such as user IDs are encrypted. This can improve the security of the system and prevent users from accessing other people's data by tampering with URL parameters. In order to realize the function of hiding routing parameters, we can use the "Path Parameter Rewrite (Rewrite)" function provided by Vue Router. Specifically, we can redefine the value of the routing parameter by adding the beforeEnter function in the routing configuration, for example:

{ 
  path: '/user/:id', 
  component: User,
  beforeEnter: (to, from, next) => {
    // 将id进行加密
    const id = encrypt(to.params.id)
    next({ path: `/user/${id}` })
  }
}

In the above code, we define a function named "beforeEnter", which will Called before the user accesses the route. In this function, we encrypt the original routing parameters and modify the path of the jump route to the encrypted path value through the next function, thus hiding the routing parameters.

3. Decryption of routing parameters

When routing parameters are hidden, we need to decrypt the routing parameters in the component to obtain the real parameter values. In order to achieve this function, we can decrypt the routing parameters in the component's created life cycle function, for example:

const User = {
  template: '<div>{{ realId }}</div>',
  data() {
    return {
      realId: ''
    }
  },
  created() {
    // 获取加密后的id路由参数
    const id = this.$route.params.id
    // 解密id
    this.realId = decrypt(id)
  }
}

In the above code, we obtain the encrypted routing parameters through the created life cycle function, And convert it into a real parameter through the decryption function decrypt, and save the decrypted value in the instance variable realId of the component. In the template, we can display the real routing parameter values ​​through the realId variable.

4. Summary

By using the path parameter rewriting function, we can easily hide and decrypt Vue routing parameters. This technology can improve the security of the system and avoid unnecessary troubles. In actual development, we can also combine cookies, sessions and other technologies to further improve the security of the system.
