How to use Vue and NetEase Cloud API to develop an intelligent music recommendation engine

Introduction:
The intelligent music recommendation engine is a currently popular music recommendation technology that can be based on the user's preferences and interests. Recommend music that suits them. This article will introduce how to use Vue.js and NetEase Cloud API to develop an intelligent music recommendation engine.

1. Project preparation
First, we need to create a Vue project. You can quickly build the basic structure of the project through the Vue CLI officially provided by Vue. Execute the following command on the command line to create a new Vue project:

vue create music-recommendation

After executing this command, follow the command line prompts to configure, including selecting project features, installing dependencies, etc. Once completed, go into the project directory.

2. Introducing NetEase Cloud API
In order to obtain music data, we need to use NetEase Cloud API. NetEase Cloud provides a rich interface, and we can obtain various music data such as playlists and popular songs. First, we need to register a NetEase Cloud developer account and apply for a developer key. After the application is approved, we can use the functions provided by the API.

Next, create an .env file in the root directory of the project to store the key information of the NetEase Cloud API. Add the following content to .env:

VUE_APP_NETEASE_API_KEY=your_api_key

Please replace your_api_key with your real API key.

Then, create the utils folder in the src directory and create a netease.js file in the utils folder. Add the following code to the netease.js file:

import axios from 'axios'

const netease = axios.create({
  baseURL: 'https://netease-api.com/v1',
  headers: {
    'Content-Type': 'application/json'
  }
})

export function getPlaylistDetail(playlistId) {
  return netease.get(`/playlist/detail?id=${playlistId}`)
    .then(response => response.data)
}

export function getRecommendSongs(limit) {
  return netease.get(`/recommand/songs?limit=${limit}`)
    .then(response => response.data.songs)
}

The above code uses the axios library to send HTTP requests, and uses the interface provided by NetEase Cloud API to obtain music data. The getPlaylistDetail function is used to obtain the detailed information of the playlist, and the getRecommendSongs function is used to obtain the recommended song list.

3. Create Vue component
We can use the function in the netease.js file written in the previous step in the Vue component to obtain music data and display it on the page. Create the components folder in the src directory, and create a MusicRecommendation.vue file in the components folder.

Add the following code in MusicRecommendation.vue:

<template>
  <div>
    <h1>智能音乐推荐引擎</h1>
    <div v-if="loading">加载中...</div>
    <ul>
      <li v-for="song in songs" :key="song.id">
        {{ song.name }} - {{ song.artist }}
      </li>
    </ul>
  </div>
</template>

<script>
import { getRecommendSongs } from '@/utils/netease'

export default {
  data() {
    return {
      songs: [],
      loading: true
    }
  },
  mounted() {
    getRecommendSongs(10)
      .then(songs => {
        this.songs = songs
        this.loading = false
      })
      .catch(error => {
        console.error(error)
        this.loading = false
      })
  }
}
</script>

The above code defines a MusicRecommendation component, which uses the v-for directive to display the song list on the page . In the mounted hook function, we called the getRecommendSongs function to obtain the song data and assigned the result to the songs variable in data.

4. Register components and routing
Create a router folder in the src directory, and create an index.js file in the router folder. Add the following code to the index.js file:

import Vue from 'vue'
import VueRouter from 'vue-router'
import MusicRecommendation from '@/components/MusicRecommendation.vue'

Vue.use(VueRouter)

const routes = [
  {
    path: '/',
    name: 'MusicRecommendation',
    component: MusicRecommendation
  }
]

const router = new VueRouter({
  routes
})

export default router

The above code creates a VueRouter instance and defines a routing rule to map the root path '/' to the MusicRecommendation component.

Next, open the main.js file in the src directory and add the following content at the beginning of the file:

import router from '@/router'

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

The above code will add the created VueRouter instance to the Vue instance.

5. Run the project
At this point, we have completed the development of the intelligent music recommendation engine. Execute the following command in the command line to run the project:

npm run serve

Then, visit http://localhost:8080 in the browser, you will see a page showing recommended songs.
