Vue practical tutorial: How to use NetEase Cloud API to realize the configurability of the song recommendation algorithm

Introduction
Today's music recommendation algorithms have become very intelligent. NetEase Cloud Music is one of the most popular music platforms in China, and its recommendation algorithm is also very popular among users. This article will lead readers to implement a configurable song recommendation algorithm using the Vue framework and NetEase Cloud API.

1. Set up the Vue development environment
First, we need to set up the Vue development environment. Open the terminal and execute the following command to install Vue-cli:

npm install -g @vue/cli

After the installation is complete, execute the following command to create a new Vue project:

vue create music-recommendation

After installing the dependencies, enter the project directory:

cd music-recommendation

Then use the following command to start the Vue development server:

npm run serve

Now, we have successfully set up the Vue development environment.

2. Configure and obtain access rights to NetEase Cloud API
To implement the song recommendation algorithm, we need to use NetEase Cloud Music's API to obtain song data. First, we need to apply for a developer account on the NetEase Cloud open platform and create a new application. When creating an application, you need to pay attention to obtaining the App Key and App Secret of the application.

Next, we need to configure Axios in the Vue project to send HTTP requests. Find the src directory in the project root directory, create a file named api.js, and add the following code in it:

import axios from 'axios';

const instance = axios.create({
  baseURL: 'https://api.netease.com',
});

export default instance;

Then, introduce api.js in the main.js file:

import axios from './api';

Vue.prototype.$http = axios;

Now we have configured the access permissions of Axios and NetEase Cloud API.

3. Implement the song recommendation algorithm
Create a component file named Recommend.vue in the src directory, and add the following code to it:

<template>
  <div>
    <h1 id="歌曲推荐">歌曲推荐</h1>
    <ul>
      <li v-for="song in songs" :key="song.id">
        <img src="/static/imghwm/default1.png"  data-src="song.picUrl"  class="lazy"  : alt="歌曲封面">
        <span>{{ song.name }}</span>
        <span>{{ song.artist }}</span>
      </li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      songs: [],
    };
  },
  mounted() {
    this.getRecommendSongs();
  },
  methods: {
    getRecommendSongs() {
      this.$http.get('/playlist/detail?id=3778678')
        .then(response => {
          this.songs = response.data.playlist.tracks;
        })
        .catch(error => {
          console.error(error);
        });
    },
  },
};
</script>

Through the above code, we The song list details with ID 3778678 are obtained from the Recommend.vue component, and the song data is rendered on the page. You can modify the playlist ID or data display method according to your own needs.

4. Configuring the configurability of the recommendation algorithm
In order to achieve the configurability of the recommendation algorithm, we can add some interactive elements to the Recommend.vue component so that users can adjust the rules for recommended songs. Taking the recommendation of the latest 10 songs as an example, we can add an input element to the component to enter the number of recommended songs.

First, add the following code to the template of Recommend.vue:

<input type="number" v-model.number="recommendCount" min="1">
<button @click="getRecommendSongs">获取推荐歌曲</button>

Then, add the following code to the script of Recommend.vue:

data() {
  return {
    songs: [],
    recommendCount: 10,
  };
},

Finally, modify getRecommendSongs Request address in the method:

this.$http.get(`/playlist/detail?id=3778678&limit=${this.recommendCount}`)

Now, users can freely enter the number of songs they want to recommend through the input box, and click the button to get the recommended songs.

Conclusion
Through the practical tutorial of this article, we learned how to use the Vue framework and NetEase Cloud API to implement a configurable song recommendation algorithm. By configuring the number of recommendations, we can freely obtain more or fewer song recommendation results according to our needs. I hope that through this example, readers can become more familiar with the use of Vue and flexibly use the API to implement more interesting functions.
