How Vue3 uses axios

Title: Data Requests in Vue 3 with Axios

text:

Axios is a popular JavaScript library for making HTTP requests in the browser and Node.js. It provides a clean API that makes it easy to send asynchronous requests and process response data. In Vue 3, we can use Axios to interact with the backend data. This article will introduce how to integrate and use Axios in Vue 3.

step:

This is a simple example showing how to use Axios for data requests in Vue 3. By integrating Axios, we can easily send asynchronous requests and process response data. I hope this article can help you successfully use Axios for data interaction in Vue 3 projects.

Reference: Axios Official Documentation: Getting Started | Axios Docs

1. Install Axios: First, install Axios in your Vue 3 project. Open a terminal, go to your project root directory, and run the following command:

   npm install axios
   

   This will install the Axios library and its dependencies.

2. Introduce Axios: In the component that needs to use Axios, importintroduce Axios through the keyword:

   import axios from 'axios';
   

   Sending a GET request: Sending a GET request with Axios is very simple. In a method or lifecycle hook that needs to send a request, use the following code to send a GET request:

3. axios.get('/api/data')
     .then(response => {
       // 处理响应数据
     })
     .catch(error => {
       // 处理请求错误
     });
   

   In the above example, we sent a GET request to /api/datathe interface, and thenhandled the success response through the method, and catchhandled the request error through the method.

4. Send a POST request: If you need to send a POST request, you can use axios.postthe method. Here is an example of sending a POST request:

5. axios.post('/api/data', { data: 'example' })
     .then(response => {
       // 处理响应数据
     })
     .catch(error => {
       // 处理请求错误
     });
   

   In the above example, we sent a POST request to /api/datathe interface and passed a data object.

6. Using other functions of Axios: Axios provides many other functions, such as setting request headers, handling request timeouts, intercepting requests and responses, etc. You can refer to the official documentation of Axios to know more details about these functions.
