Quick Start with Vue: How to implement the music ranking function through NetEase Cloud API

Introduction:
Vue is a popular JavaScript framework that simplifies the process of front-end development. In this article, we will learn how to use the Vue framework and NetEase Cloud API to implement a music ranking function. We will build this application using Vue's features such as components, data binding, and lifecycle hooks.

Step 1: Create a project
First, we need to create a project based on Vue. Open a terminal and run the following command to create a new project directory and enter it:

vue create music-ranking
cd music-ranking

Then select the default options to create a basic Vue project. After the installation is complete, run the following command to start the service:

npm run serve

This will run a default Vue application locally on which we will develop.

Step 2: Obtain the NetEase Cloud API key
In order to use the NetEase Cloud Music API, we need to obtain an API key first. Open the NetEase Cloud Developer Platform and register a new account. After logging in, create a new app and get the generated API key.

Step 3: Create components
Create a new folder components under the src folder, and then create a Vue component named Ranking in it. In the Ranking.vue file, we will write code to display the music rankings.

<template>
  <div>
    <h1>{{ rankingTitle }}</h1>
    <ul>
      <li v-for="song in songs" :key="song.id">{{ song.name }}</li>
    </ul>
  </div>
</template>

<script>
export default {
  data() {
    return {
      rankingTitle: '',
      songs: []
    }
  },
  mounted() {
    this.fetchRankingData()
  },
  methods: {
    fetchRankingData() {
      // 使用axios发送HTTP请求
      // 将你的API密钥替换成你自己的
      const apiKey = 'YOUR_API_KEY'
      const apiUrl = `http://api.music.163.com/ranking?id=3778678&apikey=${apiKey}`

      axios.get(apiUrl)
        .then(response => {
          this.rankingTitle = response.data.playlist.name
          this.songs = response.data.playlist.tracks
        })
        .catch(error => {
          console.log(error)
        })
    }
  }
}
</script>

In the above code, we use Vue’s component options to define the component’s template and logic. We defined two variables in the data option: rankingTitle is used to store the title of the ranking, and songs is used to store the song list. In the mounted hook function, we called the fetchRankingData method to obtain the ranking data, and assigned the returned data to the rankingTitle and songs variables respectively.

Step 4: Use components
In the App.vue file, we will use the Ranking component we just created to display the music ranking function. Add the following code to the App.vue file:

<template>
  <div id="app">
    <Ranking />
  </div>
</template>

<script>
import Ranking from './components/Ranking'

export default {
  components: {
    Ranking
  }
}
</script>

In the above code, we use the import statement to import the Ranking component into the App component and register the Ranking component in the components option. Then we used the tag in the template to render the Ranking component.

Step 5: Run the application
Run the following command to start the application:

npm run serve

Open http://localhost:8080/ in the browser, you will see a simple Music ranking page, the default ranking data of NetEase Cloud Music will be displayed on the page.

Conclusion:
Through the guidance of this article, we learned how to use the Vue framework and NetEase Cloud API to implement a music ranking function. We created a Ranking component to display ranking data and obtain the data by sending an HTTP request. This example covers basic concepts such as Vue components, data binding and life cycle hooks, and hopes to help beginners get started with the Vue framework quickly.
