下面是所做的工作 获取WAV文件=>确定

The following are done work Get WAV file => OK

private function renderWav(src, convertToMp3 = false) {
    WaveFile.writeBytesToWavFile(myWavFile, myWavData, 44100, 2, 16)       
}

转换为MP3 =>确定

private function makeIntoMp3(wav) {
    mp3Encoder = new ShineMP3Encoder(wav);
    mp3Encoder.start();
}

保存MP3文件，客户端=>确定

private function onWavClick(e:MouseEvent) {
   new FileReference().save(mp3Encoder.mp3Data, "MyAudio.mp3");
}

以上，我可以在客户端，但是，我的问题一个MP3文件保存到服务器端（PHP）

Above, I can get a MP3 file in client side but on my problem that save to Server side(PHP)

保存到服务器端=>失败

public function makeMP3File() {
   var urlVariables:URLVariables = new URLVariables;
   urlVariables.mp3Data = mp3Encoder.mp3Data;           
   var req:URLRequest = new URLRequest('upload.php');
   req.data = urlVariables;
   req.method = URLRequestMethod.POST;
   var loader:URLLoader = new URLLoader();
   loader.load(req);
}

我的PHP code

function strean2audio($audioStream, $filename)
{
   $file = fopen($filename . '.mp3', "wb");
   fwrite($file, $audioStream);
   fclose($file);
}

我是个菜鸟动作，不知道是哪个部分的错误， 感谢您的帮助！的

I was a ActionScript rookie, don't know which part error, thanks for your help!

推荐答案

我找到解决我的问题（仅供参考）的方式

I find the way to solve my problem ( For your reference )

// FLASH化妆MP3文件到服务器

// FLASH make MP3 file to server

public function makeMP3File() {
  var sba:ByteArray = mp3Encoder.mp3Data;    **//to ByteArray**
  var req:URLRequest = new URLRequest('upload.php');
  req.contentType = 'application/octet-stream';
  req.method = URLRequestMethod.POST;
  req.data = sba;           
  var loader:URLLoader = new URLLoader(req);
}

// PHP服务器端

// PHP server side

function strean2audio($name, $spec, $userId=0) {
    $audio_content = file_get_contents("php://input");  **//get RAW POST**
    $file = fopen($audio_file_name . '.mp3', "wb");
    fwrite($file, $audio_content);
    fclose($file);
}

结论

recorder.MP3 - >的ByteArray - >的URLRequest - >的URLLoader - > PHP - >的ByteArray - > MP3
