How to achieve real-time updates of music search results through Vue and NetEase Cloud API

WBOYOriginal: 2023-07-20 15:33:22990browse

With the rapid development of the Internet, music sharing has become an essential part of people's lives. On music platforms such as NetEase Cloud Music, we can find a variety of music, but sometimes we may feel that the search function is not real-time enough, or perform customized searches for specific music. This article will introduce how to implement real-time updates of music search results through Vue and NetEase Cloud API.

Vue is a popular front-end framework with responsive features that can help us achieve dynamic rendering of pages and two-way binding of data. NetEase Cloud API is an interface provided by NetEase Cloud Music, through which detailed information and search results of music can be obtained.

First, we need to create a Vue instance and bind it to the DOM element of the page. You can use CDN to introduce Vue, or you can install Vue through npm.

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <title>Music Search</title>
  <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
  <div id="app">
    <input type="text" v-model="keyword" @input="searchMusic">
    <ul>
      <li v-for="song in songs" :key="song.id">{{ song.name }}</li>
    </ul>
  </div>
</body>
</html>

// index.js
const app = new Vue({
  el: '#app',
  data: {
    keyword: '',
    songs: []
  },
  methods: {
    searchMusic() {
      // 发送HTTP请求，获取音乐搜索结果
      fetch(`https://api.imjad.cn/cloudmusic/?type=search&search_type=1&s=${this.keyword}`)
        .then(response => response.json())
        .then(data => {
          this.songs = data.result.songs;
        })
        .catch(error => console.error(error));
    }
  }
});

In the above code, we created a Vue instance and defined two attributes, keyword and songs, in the data object. keyword is used to bind the value of the input box, and songs is used to store music search results. In the methods object, we define a method named searchMusic, which will be executed when the value of the input box changes.

In the searchMusic method, we use the fetch function to send an HTTP request and search for music through the NetEase Cloud API. In the returned result, we will get an array result containing music information, which we assign to the songs attribute. Due to the responsive nature of Vue, the page will automatically update based on the values of songs.

Using Vue and NetEase Cloud API, we can achieve real-time updates of music search results. When the user enters a keyword in the input box, the page will send an HTTP request based on the keyword and update the music search results. In this way, users can get more accurate search results in real time, improving user experience.

It should be noted that in order to avoid sending HTTP requests frequently, you can use the debounce function to throttle the searchMusic method. The debounce function can limit the method to be executed only once within a certain time interval to reduce the number of requests.

// index.js
const app = new Vue({
  el: '#app',
  data: {
    keyword: '',
    songs: []
  },
  methods: {
    searchMusic: _.debounce(function() {
      // 发送HTTP请求，获取音乐搜索结果
      fetch(`https://api.imjad.cn/cloudmusic/?type=search&search_type=1&s=${this.keyword}`)
        .then(response => response.json())
        .then(data => {
          this.songs = data.result.songs;
        })
        .catch(error => console.error(error));
    }, 500)
  }
});

Through the above code examples, we can achieve real-time updates of music search results through Vue and NetEase Cloud API. Hope this article is helpful to you!
