Vue technology sharing: How to use NetEase Cloud API to implement the song comment function

Introduction:
With the development of the Internet, music has become an indispensable part of people's lives. Users not only simply listen to songs, but are also eager to share their preferences with others and discuss music-related topics. This article will introduce how to use Vue and NetEase Cloud API to implement the song comment function, allowing users to freely leave messages, express opinions, and discuss the charm of music together.

1. Preparation
   Before we start, we need to prepare the required tools and environment. First, we need to install Vue, which can be installed using the npm command. Enter the following command on the command line:

   npm install -g vue

Then, introduce the Element UI component library into the Vue project to facilitate us to build the comment area. Run the following command in the project root directory:

npm install element-ui

2. Get NetEase Cloud API
   To implement the song comment function, we need to use NetEase Cloud API to obtain song information and comment content. Register an account on the NetEase Cloud Developer Platform, create a new application, and obtain the API key.
3. Create Vue component
   First, we need to create a comment component, which contains song information and comment area. Create a new component file in the src folder in the Vue project and name it SongComment.vue. In this file, we need to introduce Vue and Element UI and create a Vue component. The code is as follows:

<template>
  <div>
    <h2>{{ songName }}</h2>
    
    <!-- 评论列表 -->
    <el-card>
      <div v-for="comment in comments" :key="comment.id">
        <p>{{ comment.content }}</p>
        <p>{{ comment.time }}</p>
      </div>
    </el-card>
    
    <!-- 评论输入框 -->
    <el-form>
      <el-form-item>
        <el-input v-model="newComment" placeholder="请输入评论"></el-input>
      </el-form-item>
      
      <el-form-item>
        <el-button type="primary" @click="submitComment">发表评论</el-button>
      </el-form-item>
    </el-form>
  </div>
</template>

<script>
import Vue from 'vue'
import ElementUI from 'element-ui'
Vue.use(ElementUI)

export default {
  data () {
    return {
      songName: '烟花易冷',  // 歌曲名字
      comments: [],  // 评论列表
      newComment: ''  // 输入框中的新评论
    }
  },
  methods: {
    // 获取歌曲评论
    getComments () {
      // 使用axios等工具发送请求获取评论内容，并将其赋值给comments变量
    },
    // 提交新评论
    submitComment () {
      if (this.newComment === '') {
        return
      }
      
      // 使用axios等工具发送请求，将新评论提交到后台
    }
  },
  created () {
    // 组件创建完成后，获取评论内容
    this.getComments()
  }
}
</script>

In the above code, we introduced the Vue and Element UI libraries, and defined songName, comments and # in data ##newCommentThree variables. songName is used to display the song name, comments is used to store the comment list, newComment is a two-way bound input box where users can enter new comments content.

In

methods, we define two methods getComments and submitComment. getComments is used to get the song comment content from the background, and submitComment is used to submit new comments to the background.

Finally, in the

created life cycle hook, we call the getComments method to get the comment content.

Use NetEase Cloud API to obtain comment content
4. In the above code, we called an unimplemented function
   axios in the getComments method. Send a request to get review content. NetEase Cloud API will be used below to implement this function.

First, introduce axios at the top of the

SongComment.vue file and modify the getComments method in methods. The code is as follows:

<script>
import Vue from 'vue'
import ElementUI from 'element-ui'
import axios from 'axios'
Vue.use(ElementUI)

export default {
  // ...
  methods: {
    getComments () {
      axios.get('http://musicapi.163.com/api/v1/comments', {
        params: {
          songId: '123456'  // 替换成你需要获取评论的歌曲ID
        }
      })
      .then(response => {
        this.comments = response.data
      })
      .catch(error => {
        console.error(error)
      })
    },
    // ...
  },
  // ...
}
</script>

In the above code, we use the GET method of axios to send a request to the comment interface of NetEase Cloud API, and pass in the song ID we need to get the comment in the URL (please replace it with your own song ID). After getting the response, assign the comment data to the

comments variable.

Submit new comments to the background
5. In the above code, we call an unimplemented function
   axios in the submitComment method to submit New comment. NetEase Cloud API will be used below to implement this function.

First, introduce axios at the top of the

SongComment.vue file and modify the submitComment method in methods. The code is as follows:

<script>
import Vue from 'vue'
import ElementUI from 'element-ui'
import axios from 'axios'
Vue.use(ElementUI)

export default {
  // ...
  methods: {
    // ...
    submitComment () {
      if (this.newComment === '') {
        return
      }
      
      axios.post('http://musicapi.163.com/api/v1/comments', {
        songId: '123456',  // 替换成你需要提交评论的歌曲ID
        content: this.newComment
      })
      .then(response => {
        // 提交成功后刷新评论列表
        this.getComments()
        
        // 清空输入框中的内容
        this.newComment = ''
      })
      .catch(error => {
        console.error(error)
      })
    }
  },
  // ...
}
</script>

In the above code, we use the POST method of axios to send a request to the comment interface of NetEase Cloud API, and pass in the song ID and comment content we need to submit a comment in the request body (please Replace with your own song ID). After successful submission, refresh the comment list and clear the content in the input box.

Use the comment component
6. In the page where you need to use the comment function, introduce the
   SongComment.vue component we created and pass in the required song ID. The code is as follows:

<template>
  <div>
    <!-- 歌曲详情 -->
    <!-- ... -->
    
    <!-- 评论组件 -->
    <song-comment :song-id="songId"></song-comment>
  </div>
</template>

<script>
import SongComment from './components/SongComment.vue'

export default {
  data () {
    return {
      songId: '123456'  // 替换成你需要展示评论的歌曲ID
    }
  },
  components: {
    SongComment
  }
}
</script>

In the above code, we introduced the

SongComment component and registered it in the components attribute. Then use the component in your template, passing in the desired song ID (please replace it with your own song ID).

Conclusion:

Through the above steps, we successfully implemented the song comment function using Vue and NetEase Cloud API. Users can leave messages, express opinions, and share their preferences with others in the comment area. Through this function, users can communicate better and explore the charm of music together. I hope this article will be helpful to developers who are learning Vue and implementing music comment functions.
