How UniApp implements music playback and music search

UniApp implementation method of music playback and music search

UniApp is a cross-platform development framework based on Vue.js. By writing a set of code, it can be used on multiple terminals (H5, applet, App, etc.) at the same time. )run. It is a common requirement to implement music playback and music search functions in UniApp. This article will introduce how to implement music playback and music search in UniApp, and provide relevant code examples.

1. Implementation method of music playback function

1. Create music playback component: First, we need to create a music playback component to control music playback, pause, previous song, Wait for the next song. You can use the uni-audio component to implement the audio playback function. The specific code is as follows:

<template>
  <view>
    <button @click="playMusic">播放</button>
    <button @click="pauseMusic">暂停</button>
    <button @click="prevMusic">上一曲</button>
    <button @click="nextMusic">下一曲</button>
  </view>
</template>

<script>
export default {
  methods: {
    playMusic() {
      uni.createInnerAudioContext().src = 'music.mp3';
      uni.createInnerAudioContext().play();
    },
    pauseMusic() {
      uni.createInnerAudioContext().pause();
    },
    prevMusic() {
      // 上一曲操作
    },
    nextMusic() {
      // 下一曲操作
    }
  }
}
</script>

In the above code, click the button to trigger the corresponding method, and use uni.createInnerAudioContext().src to copy the music file. The path points to the music file you want to play, and then the music is played through the uni.createInnerAudioContext().play() method. The pauseMusic() method is used to pause music playback. The prevMusic() and nextMusic() methods can implement the functions of the previous song and the next song according to needs.

2. Introducing the music playback component to the page: Introduce the music playback component into the page that needs to use the music playback function, and call the corresponding method to realize music playback, pause and other operations.

<template>
  <view>
    <music-player></music-player>
  </view>
</template>

<script>
import MusicPlayer from '@/components/music-player.vue';

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

In the above code, introduce the music playback component through the import statement, register the component in the components option, and then reference the component in the page.

2. Implementation method of music search function

1. Create music search component: First, we need to create a music search component for entering keywords for music search. You can use the uni-input component to implement the input box function, and call the music search interface through the uni.request method to obtain search results. The specific code is as follows:

<template>
  <view>
    <uni-input @confirm="searchMusic"></uni-input>
    <view v-for="song in searchResult" :key="song.id">
      <text>{{ song.name }}</text>
      <text>{{ song.artist }}</text>
    </view>
  </view>
</template>

<script>
export default {
  data() {
    return {
      searchResult: []
    }
  },
  methods: {
    searchMusic(e) {
      let keyword = e.detail.value;
      uni.request({
        url: 'http://api.music.com/search',
        data: {
          keyword: keyword
        },
        success: (res) => {
          this.searchResult = res.data;
        }
      });
    }
  }
}
</script>

In the above code, the keywords entered by the user are obtained through the uni-input component, and the searchMusic method is called in the confirm button click event to perform music search. Request the music search interface to the backend through the uni.request method, pass the keywords as parameters to the backend, obtain the search results and assign them to the searchResult array.

2. Introducing the music search component to the page: The music search function can be realized by introducing the music search component to the page where the music search function is required.

<template>
  <view>
    <music-search></music-search>
  </view>
</template>

<script>
import MusicSearch from '@/components/music-search.vue';

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

In the above code, introduce the music search component through the import statement, register the component in the components option, and then reference the component in the page.

In summary, through the above steps, we can implement music playback and music search functions in UniApp. The music playback function can be achieved by creating a music playback component and introducing the component in the pages that need to be used, and calling the corresponding methods to implement music playback, pause and other operations; the music search function can be achieved by creating a music search component and introducing it in the pages that need to be used. This component is introduced in to realize the function of entering keywords for music search. I hope this article can provide some help to UniApp developers in implementing music playback and music search functions.
