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

In recent years, music recommendation systems have attracted more and more attention and love. By analyzing the user's listening habits, preferences and favorite songs through intelligent algorithms, it can recommend music works that suit the user's taste and increase the user's stickiness and user experience. This article will introduce how to use Vue and NetEase Cloud API to develop an intelligent music recommendation system to provide users with personalized music recommendations.

1. Preparation work
Before starting development, we need to complete some preparation work. First, create a developer account on the NetEase Cloud Music official website and obtain the developer ID and developer key. Then, build a Vue project. You can use the Vue CLI tool officially provided by Vue to create a Vue project.

2. Introducing NetEase Cloud API
In the Vue project, we can use Axios to send HTTP requests. First, install Axios in the project:

npm install axios --save

Then, where we need to use the API, we can introduce Axios and use its API:

import axios from 'axios'

axios.get('https://api.example.com/mysongs').then(response => {
  console.log(response.data)
}).catch(error => {
  console.log(error)
})

Among them, https://api.example. com/mysongs is a sample API address, you need to replace it with the address of NetEase Cloud API.

3. Authorized login
NetEase Cloud API uses OAuth2 authorization, so we need to implement the authorized login function in the Vue project. First, in the click event of the login button, send a GET request to the authorized login interface of NetEase Cloud API:

login() {
  window.location.href = `https://api.example.com/oauth2/authorize?client_id=${clientId}&redirect_uri=${redirectUri}&response_type=code`;
}

Among them, https://api.example.com/oauth2/authorize is the NetEase Cloud API Authorization login interface, clientId is the Client ID of the application you created on the NetEase Cloud Music Developer Platform, and redirectUri is the URL that will be redirected after successful authorization.

Then, the NetEase Cloud API will redirect to the redirectUri you specify and include an authorization code in the URL parameter. We can get this authorization code in the authorization page of the Vue project and save it to the current user's status:

mounted() {
  const code = this.$route.query.code
  if (code) {
    this.$store.commit('setCode', code)
  }
}

Here we use Vue's status management tool Vuex to save the authorization code. You can according to your own project Requirements to choose a status management tool.

4. Obtain personalized recommended music
After the authorized login is successful, we can obtain personalized recommended music by sending a request to the NetEase Cloud API. First, before sending a request, you need to use the stored authorization code to obtain the access token:

axios.post('https://api.example.com/oauth2/token', {
  client_id: clientId,
  client_secret: clientSecret,
  grant_type: 'authorization_code',
  redirect_uri: redirectUri,
  code: code
}).then(response => {
  console.log(response.data.access_token)
  // 保存访问令牌到状态管理器中
}).catch(error => {
  console.log(error)
})

Among them, https://api.example.com/oauth2/token is the token acquisition interface of NetEase Cloud API , clientSecret is the developer key and needs to be used together with clientId.

Then, we can use the obtained access token to obtain personalized recommended music:

axios.get('https://api.example.com/recommendations', {
  headers: {
    Authorization: 'Bearer ' + accessToken
  }
}).then(response => {
  console.log(response.data)
}).catch(error => {
  console.log(error)
})

Among them, https://api.example.com/recommendations is an example of personalized music Recommended music interface, you need to replace it with the actual address of NetEase Cloud API.

5. Display recommended music
After obtaining personalized recommended music, we can display it on the homepage of the Vue project. First, in the created hook function of the Vue component, send a request to obtain personalized recommended music:

created() {
  axios.get('https://api.example.com/recommendations', {
    headers: {
      Authorization: 'Bearer ' + accessToken
    }
  }).then(response => {
    this.songs = response.data
  }).catch(error => {
    console.log(error)
  })
}

Then, use the v-for directive in the template to render the recommended music in a loop:

<div v-for="song in songs" :key="song.id">
  <img src="/static/imghwm/default1.png"  data-src="song.cover"  class="lazy"  : alt="cover" />
  <p>{{ song.name }}</p>
  <p>{{ song.artist }}</p>
</div>

Among them, songs is an array that stores the obtained personalized music recommendation information.

Through the above steps, we can use Vue and NetEase Cloud API to develop an intelligent music recommendation system. Users log in through authorization, and the system will recommend personalized music works based on the user's preferences. This not only improves the user experience, but also brings a better entertainment experience to music lovers. I hope this article can be helpful to your development work!
