How to hide address bar parameters in Vue.js

When using Vue.js to develop front-end projects, the processing of URL address bar parameters is a very basic but important issue. In many cases, we need to get parameters from the URL. For example, when jumping from the previous page to the current page, we need to pass some information to this page. In this case, we need to pass this information to the URL in the form of parameters. However, sometimes these parameters need to be hidden. After all, sensitive information in the URL should not be easily leaked. Therefore, this article will introduce how to hide the address bar parameters in Vue.js.

1. Dynamic routing

First of all, we can hide the parameters in the address bar through Vue.js's dynamic routing. Dynamic routing is a technique that maps parameters in the URL to the actual components being displayed. For example, we assume that there is an article list page. Each article has a unique ID to identify this article. We can use this ID as a parameter of the route, and then read this ID in the component and use it. to obtain the corresponding article information.

Specifically, we can first define a dynamic route in the routing configuration and set a certain segment of the routing path (such as article ID) as a dynamic parameter:

const router = new VueRouter({
  routes: [
    {
      path: '/article/:id',
      name: 'Article',
      component: Article
    }
  ]
})

In this example , :id is a dynamic parameter representing the ID of the article. In the corresponding component, we can get the value of this parameter through $route.params.id:

export default {
  mounted () {
    console.log(this.$route.params.id)
  }
}

In this way, when the user accesses this route, it can be obtained in the component to the value of the parameter, and this parameter will not be displayed in the URL.

2. Query parameters

In addition to using dynamic routing, we can also use Query parameters to hide parameters in the address bar. Query parameters are key-value pairs separated by ?, which can pass various parameters to the URL in the form of strings.

For example, we assume that there is a search page, and the keywords entered by the user need to be passed to the server when searching to obtain matching results. The entered keywords can be used as Query parameters, and then in the routing component Get and parse this parameter in:

const router = new VueRouter({
  routes: [
    {
      path: '/search',
      name: 'Search',
      component: Search
    }
  ]
})

// 当用户在输入框中输入搜索关键词时
this.$router.push({
  name: 'Search',
  query: { keyword: '关键词' }
})

export default {
  mounted () {
    console.log(this.$route.query.keyword)
  }
}

In this example, the query option represents the passed parameter. Then in the component, you can get the value of this parameter through $route.query.keyword. In this way, the actual parameters passed will not be visible in the URL.

3. Use encrypted parameters in the URL

In addition to the above two methods, we can also use encrypted parameters in the URL to hide the address bar parameters. Specifically, we can encrypt the parameters before passing them to the URL, so that even if the URL is intercepted by others, the actual parameter values ​​cannot be easily parsed.

There are many ways to encrypt, you can use symmetric encryption (such as DES, AES) or asymmetric encryption (such as RSA) and other algorithms for encryption. Not much introduction here.

When using encrypted parameters in Vue.js, you can write the encrypted parameters into local storage such as Cookie or LocalStorage, and then let subsequent pages read this data and decrypt it. This ensures that encrypted parameters are only displayed in local storage and not exposed to the URL. The only thing that needs to be noted is that the length of the encrypted parameters should be smaller than the length of the plain text parameters, otherwise the memory of Cookie and other storage will be too large.

The above are three ways to hide address bar parameters in Vue.js. No matter which method is used, we need to ensure that the parameter values ​​in the URL are hidden as much as possible while ensuring security. Admittedly, this is not a simple matter, but in actual development, this issue is very important for some sensitive data.
