Where is the vue network request written?

Vue is a front-end framework that provides us with a lot of support we need during development, one of which is support for network requests. Vue's network requests can be implemented using the third-party library Axios or Vue's own Ajax library. When choosing which method to use, we need to consider the actual situation of the project. This article will introduce the implementation of network requests in Vue and summarize the best practices.

Axios

Axios is a Promise-based HTTP client that we can use in Vue projects to make network requests. The code example of using Axios to send a GET request is as follows:

import axios from 'axios' axios.get('/api/posts') .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

The code example of using Axios to send a POST request is as follows:

import axios from 'axios' axios.post('/api/posts', { title: 'test', content: 'test content' }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

The code example of using Axios to send a PUT request is as follows:

import axios from 'axios' axios.put('/api/posts/1', { title: 'test', content: 'test content' }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

Axios also provides other methods, such as DELETE, PATCH, etc., choose according to project needs. In the configuration of Axios, we can specify headers, timeouts, and some other configuration items to meet the needs of our project. We can configure it according to the actual situation. Axios is a very easy-to-use network request library that is currently widely used in Vue projects.

Vue Ajax

Vue Ajax is the Ajax library that comes with Vue. It provides a Vue plug-in that can use Vue.prototype.$http to make Ajax requests. The code example for using Vue Ajax to make a GET request is as follows:

Vue.http.get('/api/posts') .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

The code example for using Vue Ajax to make a POST request is as follows:

Vue.http.post('/api/posts', { title: 'test', content: 'test content' }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

The code example for using Vue Ajax to make a PUT request is as follows:

Vue.http.put('/api/posts/1', { title: 'test', content: 'test content' }) .then(function (response) { console.log(response); }) .catch(function (error) { console.log(error); });

Vue Ajax also provides other methods, such as DELETE, PATCH, etc., which are similar to Axios methods. Vue Ajax can perform global configuration and local configuration. Global configuration can be set with Vue.http.options.goods. The Vue Ajax library is lighter than Axios, but it does not have the rich API of Axios.

Best Practice

When choosing a network request library, we need to consider the actual situation of the project, and then choose the network request method that is most suitable for the project. Axios and Vue Ajax are both great options. If you need a rich API and have a large amount of network requests, Axios is a better choice. If you need a lightweight Ajax library and don't have too many network requests, Vue Ajax is a good choice.

Before making network requests, it is best to use asynchronous requests for data loading in the life cycle of Vue. By using hook functions, we can make network requests when the component is created. An example is as follows:

export default { data() { return { posts: [] } }, created() { this.getPosts() }, methods: { getPosts() { Vue.http.get('/api/posts') .then((response) => { this.posts = response.data }) } } }

In the above code, we call the getPosts method in the created hook function, which uses Vue Ajax to send a GET request. After successfully obtaining the data, this method assigns the data to the component's data attribute.

Summary

Vue’s network requests are very important. We can use Axios or Vue Ajax to make network requests. When choosing a network request, you need to make a choice based on your project needs. Before sending a request, it is best to make an asynchronous request in Vue's life cycle for data loading. Using best practices can help us make better network requests and improve the performance of Vue applications.
