Vue Advanced Tutorial: How to implement automatic recommendation of music playlists through NetEase Cloud API

Abstract:
In this article, we will introduce how to use the Vue framework and NetEase Cloud API to achieve Automatic recommendation function for music playlists. Through this tutorial, you will learn how to build a simple music recommendation application through Vue's component development method, and use NetEase Cloud API to obtain music data. Finally, we will use code examples to show how to implement the automatic recommendation function.

1. Preparation
Before starting, we need to make sure that the Vue scaffolding and related dependencies have been installed. You can use the following command to check whether the installation has been successful:

# 检查Vue是否成功安装
vue --version

2. Create a Vue project
First, we need to use Vue scaffolding to create a new project. Use the following command to create a project named "music-recommendation":

# 创建项目
vue create music-recommendation

3. Install dependencies
Next, go to the project folder and install the necessary dependencies:

# 进入项目文件夹
cd music-recommendation

# 安装axios
npm install axios --save

axios is a commonly used network request library, we will use it to request NetEase Cloud API to obtain music data.

4. Create a component
First, we need to create a component named "Recommendation". Create a Recommendation.vue file under the src/components folder and fill in the following code:

<template>
  <div>
    <h2>音乐推荐</h2>
    <ul>
      <li v-for="song in songs" :key="song.id">
        {{ song.name }}
      </li>
    </ul>
  </div>
</template>

<script>
import axios from 'axios';

export default {
  data() {
    return {
      songs: []
    };
  },
  mounted() {
    this.fetchSongs();
  },
  methods: {
    fetchSongs() {
      axios.get('https://api.music.163.com/recommend/songs')
        .then(response => {
          this.songs = response.data;
        })
        .catch(error => {
          console.error(error);
        });
    }
  }
};
</script>

5. Using components
Next, we need to add the Recommendation component to the App.vue file. Open the src/App.vue file and modify the code as follows:

<template>
  <div id="app">
    <img alt="Vue logo" src="./assets/logo.png">
    <Recommendation />
  </div>
</template>

<script>
import Recommendation from './components/Recommendation.vue';

export default {
  name: 'App',
  components: {
    Recommendation
  }
};
</script>

6. Run the project
Now, we have completed writing the code. Run the following command to start the project:

npm run serve

Open http://localhost:8080/ in the browser, you should be able to see a simple music recommendation page and display the music obtained through the NetEase Cloud API music data.

7. Implement the automatic recommendation function
Now, we need to make some modifications to the code to realize the automatic recommendation function. First, we need to add a timer in the methods of the Recommendation component and call the fetchSongs method every once in a while to obtain the latest music data. Modify the code as follows:

// ...
methods: {
  fetchSongs() {
    axios.get('https://api.music.163.com/recommend/songs')
      .then(response => {
        this.songs = response.data;
      })
      .catch(error => {
        console.error(error);
      })
      .finally(() => {
        setTimeout(this.fetchSongs, 30000); // 每30秒调用一次fetchSongs方法
      });
  }
}
// ...

8. Summary
Through this tutorial, we learned how to use the Vue framework and NetEase Cloud API to implement the automatic recommendation function of music playlists. We used Vue's component development method to build a simple music recommendation application, and requested the NetEase Cloud API to obtain music data through the axios library. Finally, we show how to implement the automatic recommendation function through a code example. I hope this tutorial will be helpful to your advanced learning of Vue.
