我正在尝试上传录制的音频，但我总是在服务器端获得一个空文件...

这是我的录音代码：

    var currentSessionMode = Titanium.Media.audioSessionMode; Titanium.Media.audioSessionMode = Ti.Media.AUDIO_SESSION_MODE_PLAY_AND_RECORD; var recording = Ti.Media.createAudioRecorder();
// default compression is Ti.Media.AUDIO_FORMAT_LINEAR_PCM
// default format is Ti.Media.AUDIO_FILEFORMAT_CAF

// this will give us a wave file with µLaw compression which
// is a generally small size and suitable for telephony recording
// for high end quality, you'll want LINEAR PCM - however, that
// will result in uncompressed audio and will be very large in size
recording.compression = Ti.Media.AUDIO_FORMAT_ULAW;
recording.format = Ti.Media.AUDIO_FILEFORMAT_WAVE;

Ti.Media.addEventListener('recordinginput', function(e) {
    Ti.API.info('Input availability changed: '+e.available);
    if (!e.available && recording.recording) {
        b1.fireEvent('click', {});
    }
});

win.addEventListener('close',function(e) {
    Titanium.Media.audioSessionMode = currentSessionMode;
});

var file;
var timer;
var sound;


var label = Titanium.UI.createLabel({
    text:'',
    top:150,
    color:'#999',
    textAlign:'center',

});

win.add(label);

function lineTypeToStr()
{
    var type = Ti.Media.audioLineType;
    switch(type)

这是我的PHP接收我的数据并将其发送到电子邮件：

<?php 

    $mailto = "mailto@mailto.com";
    $subject = "teste";
    $message = "mensagem teste";

    print_r( $_FILES );

    $file = $_FILES['userfile']['name'];
    $file_size = $_FILES['userfile']['size'];
    $handle = fopen($file, "r");
    $content = fread($handle, $file_size);
    fclose($handle);
    $content = chunk_split(base64_encode($content));

    // a random hash will be necessary to send mixed content
    $separator = md5(time());

    // carriage return type (we use a PHP end of line constant)
    $eol = PHP_EOL;

    // main header (multipart mandatory)
    $headers = "From: FeedBack Team <feedbackMail@feedback.com.br>" . $eol;
    $headers .= "MIME-Version: 1.0" . $eol;
    $headers .= "Content-Type: multipart/mixed; boundary=\"" . $separator . "\"" . $eol . $eol;
    $headers .= "Content-Transfer-Encoding: 7bit" . $eol;
    $headers .= "This is a MIME encoded message." . $eol . $eol;

    // message
    $headers .= "--" . $separator . $eol;
    $headers .= "Content-Type: text/plain; charset=\"iso-8859-1\"" . $eol;
    $headers .= "Content-Transfer-Encoding: 8bit" . $eol . $eol;
    $headers .= $message . $eol . $eol;

    // attachment
    $headers .= "--" . $separator . $eol;
    $headers .= "Content-Type: application/octet-stream; name=\"" . $filename . "\"" . $eol;
    $headers .= "Content-Transfer-Encoding: base64" . $eol;
    $headers .= "Content-Disposition: attachment" . $eol . $eol;
    $headers .= $content . $eol . $eol;
    $headers .= "--" . $separator . "--";

    //SEND Mail

    if (mail($mailto, $subject, "", $headers)) {
        echo "mail send ... OK"; // or use booleans here
    } else {
        echo "mail send ... ERROR!";
    }

?>

我认为我没有正确上传录制的音频。 有人可以帮我上传录制的音频吗？ 我正在使用Titanium 3.4.0 GA并开发到iOS和Android 感谢
