Question

我有一个聊天屏幕，我想从中使用react-native-audio向其后端发送语音便笺，并使用react-native-sound进行播放。

我遇到的问题是语音笔记的录制，react-native-audio中的自述文件不清楚，所以我想我的实现存在问题。

这是我的渲染方法

render() {

    return (

        <TouchableOpacity onPress={ this.start_timer }>
                <Icon name="microphone-outline" type="MaterialCommunityIcons" style={ styles.microphone_icon } />
        </TouchableOpacity>

        {
             this.state.is_recording

             ? <View style={ styles.recorder_container }>

                  <TouchableOpacity onPress={ this.clear_time }>
                      <Icon name="ios-trash" type="Ionicons" style={ styles.trash_icon } />
                  </TouchableOpacity>

                  <Text style={ styles.timer }>{ this.state.count_up.format('mm:ss') }</Text>

                  <TouchableOpacity onPress={ this.send }>
                      <Icon name="md-send" type="Ionicons" style={ styles.send_icon } />
                  </TouchableOpacity>
               </View>

            : null
        }
    )
}

这是记录和发送功能

start_timer = () => {

this.setState({ is_recording: true })

let audioPath = AudioUtils.DocumentDirectoryPath + '/test.aac';

this.audio = AudioRecorder.prepareRecordingAtPath(audioPath, {
  SampleRate: 22050,
  Channels: 1,
  AudioQuality: "Low",
  AudioEncoding: "aac"
});

this.setState({ audio: audioPath })

this.interval = setInterval(() => this.setState(prev => ({ count_up: prev.count_up.add(1, 'second') })), 1000)

}

send = async () => {

await AudioRecorder.stopRecording();

this.setState({ is_recording: false })

AudioRecorder.onFinished = async (data) => {

  let fd = new FormData();

  await fd.append('file', data.audioFileURL)

  let sound = await Api.post('api/chats/upload-vc', fd)

 }

}

clear_time = () => {

this.setState({ is_recording: false, count_up: moment().minute(0).second(0) })

clearInterval(this.interval)

}

我在后端功能中记录了该文件，但我不断得到一个空数组那我在做什么错了？

Answer 1

In your form data are you passing:

AudioUtils.DocumentDirectoryPath + '/test.aac'

as the path of the file? it's a bit unclear with your current snippet.

Also, checkout this example https://github.com/jsierles/react-native-audio/blob/master/AudioExample/AudioExample.js

我根据2016年的提示修复了音频播放器：https://github.com/zmxv/react-native-sound/issues/20#issuecomment-205683378
要将POST的文件添加到服务器，请记住在路径file://之类的前面添加"file:///data/user/0/bla.bla/files/1695695e-aaaa-4e0b-9b57-998cb6b50608.aac"。在Android Finished recording上，大小似乎仍为0 kb，但是可以使用！
我要保存在AudioUtils.DocumentDirectoryPath atm

React Native Audio将语音笔记发送到后端
