录音功能需要使用到uniapp官方文档里面的API

模版区

javascript 复制代码

<template>
	<view>
		<button @tap="startRecord">开始录音</button>
		<button @tap="endRecord">停止录音</button>
		<button @tap="playVoice">播放录音</button>
	</view>
</template>

javascript 复制代码

const recorderManager = uni.getRecorderManager();
const innerAudioContext = uni.createInnerAudioContext();
 
innerAudioContext.autoplay = true;
 
export default {
	data() {
		return {
			text: 'uni-app',
			voicePath: ''
		}
	},
	onLoad() {
		let self = this;
		recorderManager.onStop(function (res) {
			console.log('recorder stop' + JSON.stringify(res));
			self.voicePath = res.tempFilePath;
		});
	},
	methods: {
		startRecord() {
			console.log('开始录音');
 
			recorderManager.start();
		},
		endRecord() {
			console.log('录音结束');
			recorderManager.stop();
		},
		playVoice() {
			console.log('播放录音');
 
			if (this.voicePath) {
				innerAudioContext.src = this.voicePath;
				innerAudioContext.play();
			}
		}
	}
}

现在就是可以进行一个简单的录音，暂停以及播放，再根据需求进行更改即可

还有需要注意的就是在进行真机调试的时候需要判断用户是否打开了录音权限

javascript 复制代码

uni.authorize({
					scope: 'scope.record',
					success() {
						recorderManager.start({
							format: 'mp3'
						});
						t.getTimeInterval();
						uni.setInnerAudioOption({
							obeyMuteSwitch: false
						})
					},
					fail() {
						uni.showModal({
							content: '检测到您没打开录音功能权限，是否去设置打开？',
							confirmText: "确认",
							cancelText: '取消',
							success(res) {
								recorderManager.start();
								t.time = setInterval(this.timer, 50)
							}
						})
					}
				})
