How to get the current request url in vue? A brief analysis of different methods

Vue is a popular front-end framework through which responsive user interfaces can be built. During the development process, we often need to obtain the URL of the current web page so that we can take different actions in specific situations. This article will introduce different methods of getting the current request URL in Vue and their advantages and disadvantages.

1. window.location.href

The easiest way is to use the location property of the window object to get the URL of the current page. We can use the following code in the mounted lifecycle hook of the Vue component:

mounted() {
  console.log(window.location.href);
}

This will output the URL of the current web page. The advantage is that the code is easy to understand and write, but the disadvantage is that it cannot use Vue's reactive mechanism. If the URL changes, the data will not be updated automatically.

2. Vue Router

Vue Router is the official routing manager of Vue and can also be used to obtain the URL of the current page. It provides multiple APIs to get different parts of the URL, such as path, query parameters, hash values, etc. The following are some commonly used methods:

• this.$route.path: Get the current path;
• this.$route.query: Get the query parameters;
• this.$route.hash: Get the hash value.

If we need to get the current path in the Vue component, we can use the following code in the mounted lifecycle hook:

mounted() {
  console.log(this.$route.path);
}

This will output the current path. The advantage of Vue Router is that it can use Vue's responsive mechanism and provides more URL information. The disadvantage is that it requires additional configuration and management.

3. Nuxt.js

Nuxt.js is a universal application framework based on Vue.js, which can help us quickly build Vue applications and add server rendering, static generation, etc. Function. In Nuxt.js, we can get the currently requested URL by using the context object in asyncData or fetch of the Vue component. For example:

asyncData(context) {
  console.log(context.req.url);
}

This will output the current request URL. The advantage of Nuxt.js is that it can flexibly handle various URL requests and supports server rendering and static generation. The disadvantage is that it requires some understanding of the Nuxt.js framework.

Summary

There are many ways to get the URL of the current page in Vue, each method has its own advantages and disadvantages. If you only need to get a part of the URL, you can use window.location or Vue Router; if you need to get the complete URL and support responsive updates, you can use Vue Router; if you need to flexibly handle URL requests, you can use Nuxt.js. The method chosen depends on the specific needs and circumstances.
