How UniApp implements online music and song recommendations

UniApp is a cross-platform application development framework based on Vue.js. It has the characteristics of one-time development and multi-end release. This article will introduce how to use UniApp to implement online music playback and song recommendation functions.

First, we need to prepare a music API interface to obtain music data. Here, we can use the API interface of QQ Music, because QQ Music provides rich music resources and has corresponding interfaces for developers to call. The interface we use here is to get the song list and get recommended songs.

In UniApp, we first need to create a music playback page to display the music list and implement the music playback function. Create the Music folder in the pages directory, and create the music.vue file in this folder to write the code for the music playback page.

<view v-for="(item, index) in musicList" :key="index" class="music-item" @click="playMusic(item)">
  <text class="music-name">{{item.name}}</text>
  <text class="music-singer">{{item.singer}}</text>
</view>

< ;script>
export default {
data() {

return {
  musicList: [],  // 音乐列表数据
  currentMusic: {}  // 当前正在播放的音乐
}

},
methods: {

// 获取音乐列表
getMusicList() {
  // 调用API接口获取音乐列表数据并将结果赋值给musicList
  // 此处省略具体代码
},
// 播放音乐
playMusic(item) {
  // 将item赋值给currentMusic实现音乐播放功能
  this.currentMusic = item;
}

},
mounted() {

this.getMusicList();  // 在页面加载时调用getMusicList方法获取音乐列表数据

}
}

.music-item {
display: flex;
align-items: center;
margin-bottom: 10px;
cursor: pointer;
}

.music- name {
font-size: 16px;
font-weight: bold;
}

.music-singer {
margin-left: 10px;
}

The above code implements a simple music list display and music playback function. First, two data, musicList and currentMusic, are defined in data, which are used to store the music list and the currently playing music. In the getMusicList method, we obtain the music list data by calling the API interface and assign the result to musicList. In the playMusic method, we assign the clicked music to currentMusic to implement the music playback function.

Next, we need to implement the song recommendation function on the home page. Create the index.vue file in the index folder under the pages directory, which is used to write the code for the home page.

<view v-for="(item, index) in recommendList" :key="index" class="recommend-item">
  <text class="music-name">{{item.name}}</text>
  <text class="music-singer">{{item.singer}}</text>
</view>

< ;script>
export default {
data() {

return {
  recommendList: []  // 推荐歌曲列表数据
}

},
methods: {

// 获取推荐歌曲列表
getRecommendList() {
  // 调用API接口获取推荐歌曲列表数据并将结果赋值给recommendList
  // 此处省略具体代码
}

},
mounted() {

this.getRecommendList();  // 在页面加载时调用getRecommendList方法获取推荐歌曲列表数据

}
}

.recommend-item {
margin-bottom: 10px;
}

.music-name {
font-size: 16px;
font-weight: bold;
}

.music-singer {
margin-left: 10px;
}

The above code implements a simple recommended song list display . RecommendList data is defined in data, which is used to store the recommended song list. In the getRecommendList method, we obtain the recommended song list data by calling the API interface and assign the result to recommendationList.

So far, we have implemented online music playback and song recommendation functions through UniApp. On the Music page, you can click on the music list to play music, and on the homepage, you can display a recommended song list.

Note: The API interface calling part in the above code omits the specific code implementation. Developers can choose the appropriate music API interface according to their own needs and make corresponding calls in the code. At the same time, the page style can be beautified and the functions can be expanded according to specific needs.
