离子Cordova失败在IOS使用媒体插件录制音频 [英] ionic Cordova Failed recording audio on IOS using Media plugin

问题描述

我在工作离子应用程序，我需要录制音频文件，所以我使用cordova插件媒体，它工作正常为Android，但是当我试图在ios我得到这个错误：

{message：无法使用AVAudioRecorder开始录制，code：1}

这里是我的代码：

  var extension ='.wav'; 
 var name ='filename'; 
 var audio = null; 
 var filepath; 
 
 $ scope.startRecording = function（）{
 name = Utils.generateFilename（）; 
 if（device.platform ==iOS）
 {
 // var path =documents：//; 
 // var path = cordova.file.documentsDirectory; 
 // var path = cordova.file.cacheDirectory; 
 var path = cordova.file.dataDirectory; 
 path = path.replace（file：///，cdvfile：//）; 
 
} 
 else if（device.platform ==Android）
 {
 var path = cordova.file.externalApplicationStorageDirectory; 
} 
 var filename = name + extension; 
 filepath = path + filename; 
 audio = new Media（filepath，function（e）{console.log（e，success Media）;}，function（e）{console.log（e，error）;}） 
 audio.startRecord（）; 
 
}; 
 
 $ scope.sendAudioMsg = function（）{
 audio.stopRecord（）; 
 audio.release（）; 
}; 
  

当我控制台记录路径时，我得到这个：

cdvfile：//var/mobile/Containers/Data/Application/F47A76AD-E776-469F-8EFA-85B0A0F14754/Library/NoCloud/dJzSapEU6k16hV7EGrD06L29NjZcOCVzHCUTrcjEDiTCF7uUNGmCHchEcwfGls3V88p85ij0NUkv0KVagevbgh3lwWsEfmAO8uNq.wav

可以帮助我

解决方案

Android。

  var path =Android / data /+ YOUR_APP_ID +/ files /+ FILENAME +。 
 
 var myMedia = new Media（path，success，error）; 
 myMedia.startRecord（）; 
  

在完成录制后访问文件

  var path = cordova.file.externalApplicationStorageDirectory +files /+ FILENAME +。wav; 
 var myMedia1 = new Media（path，success，error）; 
 myMedia1.play（）; 
  

YOUR_APP_ID将为com.test.app

iOS，请参阅下文

  var fileName =myrec.wav; 
 var myMedia = new Media（path，success，error）; 
 myMedia.startRecord（）; 
  

要存取档案

  window.requestFileSystem（LocalFileSystem.TEMPORARY，0，function（fileSystem）{
 fileSystem.root.getFile（fileName，null，function（fileEntry）{
 fileEntry.file（function OnFileEntry （file）{
 //文件是实际记录的文件，获取路径并播放或获取base64字符串
 var reader = new FileReader（）; 
 reader.onloadend = function（evt）{ 
 evt.target.result; //这是base64字符串
}; 
 reader.readAsDataURL（file）; 
}，错误）; 
}，错误） ; 
}，error）; 
  

i'm working on an ionic App and i need to record audio files , so i used the cordova-plugin-media , it worked fine for android but when i tried it on ios i get this error :

{"message":"Failed to start recording using AVAudioRecorder","code":1}

here is my code :

var extension = '.wav';
var name = 'filename';
var audio = null;
var filepath;

$scope.startRecording = function() {
  name = Utils.generateFilename();
  if(device.platform == "iOS")
  {
     //var path = "documents://";
     //var path = cordova.file.documentsDirectory;
     //var path = cordova.file.cacheDirectory;
     var path = cordova.file.dataDirectory;
     path = path.replace("file:///", "cdvfile://");

  }
  else if(device.platform == "Android")
  {
    var path = cordova.file.externalApplicationStorageDirectory;
  }
  var filename = name + extension;
  filepath = path + filename;
  audio = new Media(filepath, function(e){console.log(e, "success Media");},function(e){console.log(e, "error");});
    audio.startRecord();

  };

  $scope.sendAudioMsg = function() {
     audio.stopRecord();
     audio.release();
  };

when i console log the path i get this :

cdvfile://var/mobile/Containers/Data/Application/F47A76AD-E776-469F-8EFA-85B0A0F14754/Library/NoCloud/dJzSapEU6k16hV7EGrD06L29NjZcOCVzHCUTrcjEDiTCF7uUNGmCHchEcwfGls3V88p85ij0NUkv0KVagevbgh3lwWsEfmAO8uNq.wav

can any one help me??

解决方案

Try following for Android.

var path = "Android/data/"+YOUR_APP_ID+"/files/"+FILENAME+".wav";

var myMedia = new Media(path, success, error);
myMedia.startRecord();

To access file after you are done with recording

var path = cordova.file.externalApplicationStorageDirectory+"files/"+FILENAME+".wav";
var myMedia1 = new Media(path, success, error);
myMedia1.play();

YOUR_APP_ID would be com.test.app

iOS, see following

var fileName = "myrec.wav";
var myMedia = new Media(path, success, error);
myMedia.startRecord();

To access file

window.requestFileSystem(LocalFileSystem.TEMPORARY, 0, function (fileSystem){
            fileSystem.root.getFile(fileName, null, function (fileEntry){
                fileEntry.file(function OnFileEntry(file){
                    // file is actual recorded file, get the path and play or get base64 string
                    var reader = new FileReader();
                    reader.onloadend = function(evt) {
                        evt.target.result; // this is base64 string
                    };
                    reader.readAsDataURL(file);
                }, error);
            }, error);
        }, error);
