This time I will show you how to call recording and playback of recording by WeChat applet. What are the precautions for WeChat applet to call recording and playback of recording. The following is a practical case, let’s take a look.
The mini program provides two recording APIs
Old version recording function
First start recording, then stop recording to pull to the temporary address of audio
Start recording:
var that = this; wx.startRecord({ success: function (res) { // 调用了停止录音接口就会触发这个函数,res.tempFilePath为录音文件临时路径 var tempFilePath = res.tempFilePath that.setData({ src: tempFilePath }) }, fail: function (res) { //录音失败的处理函数 } })
Stop recording:
wx.stopRecord()
Play recording:
wx.playVoice({ filePath: src // src可以是录音文件临时路径 })
New version recording
Get the globally unique recording manager, and then all recordings depend on it, and playing the recording requires the internal audio context innerAudioContext Object.
Get the globally unique recording manager:
var that = this; this.recorderManager = wx.getRecorderManager(); this.recorderManager.onError(function(){ // 录音失败的回调处理 }); this.recorderManager.onStop(function(res){ // 停止录音之后,把录取到的音频放在res.tempFilePath that.setData({ src: res.tempFilePath }) console.log(res.tempFilePath ) });
Start recording:
this.recorderManager.start({ format: 'mp3' // 如果录制acc类型音频则改成aac });
End recording:
this.recorderManager.stop()
Play audio:
this.innerAudioContext = wx.createInnerAudioContext(); this.innerAudioContext.onError((res) => { // 播放音频失败的回调 }) this.innerAudioContext.src = this.data.src; // 这里可以是录音的临时路径 this.innerAudioContext.play()
