Quickly get started with Vue and Axios to achieve high efficiency in front-end development

Vue.js is a popular JavaScript framework that helps developers build interactive front-end applications. Axios is a library for front-end HTTP requests that makes it easy to send and receive data from front-end applications. Combining Vue and Axios can achieve high efficiency in front-end development. This article will quickly introduce the basic usage of Vue and Axios, and provide some code examples.

1. Install and use Vue and Axios

First, install Vue and Axios in the project. You can use npm or yarn to install them. The specific operations are as follows:

1. Open the command line and switch to the project directory.

2. Enter the following commands to install Vue and Axios:

   npm install vue axios

   or

   yarn add vue axios

After the installation is complete, we can start using Vue and Axios Axios.

2. Basic usage example

1. Use Axios to send GET request in Vue

   <template>
     <div>
    <button @click="getData">发送请求</button>
    <ul>
      <li v-for="item in data" :key="item.id">{{ item.name }}</li>
    </ul>
     </div>
   </template>
   
   <script>
   import axios from 'axios';
   
   export default {
     data() {
    return {
      data: []
    };
     },
     methods: {
    getData() {
      axios.get('https://api.example.com/data')
        .then(response => {
          this.data = response.data;
        })
        .catch(error => {
          console.error(error);
        });
    }
     }
   };
   </script>
   
   <style>
   /* 样式省略 */
   </style>

2. Use Axios to send in Vue POST request

   <template>
     <div>
    <input v-model="name" type="text">
    <button @click="postData">发送请求</button>
     </div>
   </template>
   
   <script>
   import axios from 'axios';
   
   export default {
     data() {
    return {
      name: ''
    };
     },
     methods: {
    postData() {
      axios.post('https://api.example.com/data', {
        name: this.name
      })
        .then(response => {
          console.log(response.data);
        })
        .catch(error => {
          console.error(error);
        });
    }
     }
   };
   </script>
   
   <style>
   /* 样式省略 */
   </style>

3. Further use

Vue and Axios provide rich functions for more advanced usage. Here are some common further use cases:

1. Set request headers

   axios.defaults.headers.common['Authorization'] = 'Bearer ' + token;

2. Send concurrent requests

   axios.all([axios.get(url1), axios.get(url2)])
     .then(axios.spread((response1, response2) => {
    console.log(response1.data);
    console.log(response2.data);
     }));

3. Configuring request and response interceptors

   axios.interceptors.request.use(config => {
     console.log('请求拦截器');
     return config;
   }, error => {
     console.error(error);
     return Promise.reject(error);
   });
   
   axios.interceptors.response.use(response => {
     console.log('响应拦截器');
     return response;
   }, error => {
     console.error(error);
     return Promise.reject(error);
   });

The above are just some examples, the usage of Vue and Axios is much more than that. In actual development, more functions can be applied according to specific needs.

Through the introduction of this article, I believe you have mastered the basic usage of Vue and Axios, and can use them efficiently in front-end development. The combination of Vue and Axios can help you easily handle front-end HTTP requests and implement interactive front-end applications. Hope this article can be helpful to you!
