Question

我希望在为Ivr发送vxml请求时保存音频，我开发像这样的Ivr代码..

<?xml version="1.0" encoding="UTF-8"?>
<vxml version="2.1">
 <form>
    <record name="myrecording" beep="true">
      <prompt>
        Please record a message after the beep.
      </prompt>
      <filled>
        <prompt>
          You just recorded the following message: <value expr="myrecording"/>
        </prompt>
      </filled>
    </record>
  </form>
</vxml>

我希望得到msg recode并且在游戏之后。怎么做这个问题？我想用java回答。

您可以通过在记录var中添加标记来保存录制的消息，并使用PHP / JSP / ASPX等服务器端代码处理提交请求，其中包含PHP示例：
编辑：添加使用apache commons的record.jsp：http://commons.apache.org/proper/commons-fileupload/
还修改record.vxml以将数据提交到record.jsp，将record.php作为参考保存

＆＃34; record.vxml＆＃34;

<?xml version="1.0" encoding="UTF-8"?>
<vxml version="2.1">
    <form>
        <record name="myrecording" beep="true">
            <prompt>
                Please record a message after the beep.
            </prompt>
            <filled>
                <prompt>
                    You just recorded the following message: <value expr="myrecording"/>
                </prompt>
                <submit expr="record.jsp" method="post" namelist="myrecording" enctype="multipart/form-data" />      
            </filled>
        </record>
    </form>
</vxml>

＆＃34; record.php＆＃34;

<?PHP
header('Cache-Control: no-cache');
error_reporting (0);
echo "<?xml version=\"1.0\" encoding=\"UTF-8\"?>";
echo "<vxml version=\"2.0\">";
echo "<form id=\"main\">";
echo "<block>";
if ($HTTP_POST_FILES) {
foreach ($HTTP_POST_FILES as $key => $value) {
  foreach ($value as $Filename) {
   if (strpos($Filename, "WINNT")) { $ServerSide = $Filename; }
   if (strpos($Filename, ".wav")) { $ClientSide = $Filename; }
  } // for each statement
  $ServerSide = str_replace("\\\\", "/", $ServerSide);
  if (!copy($ServerSide, "c:/audio-storage/temp.wav")) {
   echo "Could not save filename: " . $ServerSide;
  } // if statement
  else {
   echo "Successfully saved filename: " . $ServerSide;
  } // else statement
} // for each statement
} // if statement
echo "</block>";
echo "</form>";
echo "</vxml>";
?>
