问题描述

我有将歌曲上传到我们 API 的应用，

I have App for upload Songs to our API,

但我找不到一个库，例如 RN-image-picker 询问用户他想选择哪张照片，

but I can't find a library for that, Like RN-image-picker that ask the user which photo he wants to choose,

除了文件特别是音频"之外，还有什么类似的东西

So is there anything like this but for File "especially Audio"

我正在尝试 react-native-fs 并使用他在 README 中提供的示例代码片段，但是当我调用它时，我在日志中得到了一个函数

I'm trying react-native-fs and use example code snippet he provides in README but when I invoke it I got a function as result in logs

chooseFile = () => {
    RNFS.readDir(RNFS.DocumentDirectoryPath)
      .then(result => {
        console.log('GOT RESULT', result); // here i got functions as result
        // stat the first file
        return Promise.all([RNFS.stat(result[0].path), result[0].path]);
      })
      .then(statResult => {
        if (statResult[0].isFile()) {
          // if we have a file, read it
          return RNFS.readFile(statResult[1], 'utf8');
        }

        return 'no file';
      })
      .then(contents => {
        // log the file contents
        console.log(contents);
      })
      .catch(err => {
        console.log(err.message, err.code);
      });
  };

编辑

在我使用 react-native-document-picker 作为@Tuan Luong 提到并编写一些函数以使用 Axios 将此文件发送到端点之后，我收到了这个错误，

EDIT

After I use react-native-document-picker as @Tuan Luong mention and write some function to send this file to the endpoint using Axios i got this error,

 Possible Unhandled Promise Rejection (id: 0):
Error: Network Error

代码

chooseFile = async () => {
    // Pick a single file
    try {
      const res = await DocumentPicker.pick({
        type: [DocumentPicker.types.audio],
      });
      let sound_uri = res.uri;
      let type = res.type;
      this.setState({
        sound_uri,
        type,
      });
    } catch (err) {
      if (DocumentPicker.isCancel(err)) {
        // User cancelled the picker, exit any dialogs or menus and move on
      } else {
        throw err;
      }
    }
  };

  sendDatet = async value => {
    const {type, sound_uri, avatar} = this.state;

    console.log(avatar, type, sound_uri, value.songName, value.generes_id);
     // Logs 
     {/*
       // avatar => file:///storage/emulated/0/Android/data/com.music/files/Pictures/image7a.jpg
      // type => audio/mpeg
      // sound_uri => content://com.android.providers.media.documents/document/audio%3A1530
     // value.songName => Test song 
     // value.generes_id => 4
