如何通过将 xml 发送到 tropo 托管脚本来使用 tropo 拨打电话？这个 php 脚本应该使用 curl 将 xml 发布到另一个 php 脚本（托管@tropo）。然后，tropo 托管的脚本应该使用 xml 来拨打电话。在下面的示例中，tropo 调试器正在接收正确的信息，因为像这样的消息显示在调试器中：

customerName:Kent is added into the context of app instance : ApplicationInstance[http://hosting.tropo.com/107029/www/ExternalPhoneHelper.php , sas_2-14-sm25ogjh4vlab5tropo]

这是将 xml 数据发送到 tropo 的 curl php 脚本：

$token = "mytoken";//removed actual token
$url = PhoneHelper::$TROPO_URL;
$xml = "
    <session>
        <token>" . $token . "</token>
        <var name=\"action\" value=\"create\"/>
        <var name=\"customerName\" value=\"Kent\" />
        <var name=\"numberToDial\" value=\"##########\" />
        <var name=\"msg\" value=\"XML Test\" />
     </session>";
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$output = curl_exec($ch);
echo curl_error($ch);
echo $output;
curl_close($ch);

接收脚本为空：

 <?php

 ?>

如果应该使用 call() 和 say() 方法，我将如何引用发布的 xml 来获取 numberToDial 和 msg？

这是调试器日志：

看起来这里有一些混乱/问题，所以我会尽力为你解决所有问题。我想讨论的第一件事是会话 API 的 XML 发布是完全可选的，它只是您可以提交“令牌请求”以启动出站呼叫的一种方式。如果你在让它工作时遇到问题，让我们跳过它，直接从浏览器尝试“plane jane”HTTP GET，直到你觉得最舒服：

api.tropo.com/1.0/sessions?action=create&token=123456&customerName=Kent&numberToDial=4075551212&msg=XML%20Test

现在回到脚本本身，我找到了你的 accountID（是的，我在Voxeo Labs / Tropo工作：P），我注意到了一些事情。首先，您拼错了应用程序 startURL，我几乎可以肯定您的意思是 ExternalPhoneHelper.php，但是您输入了 ExterMalPhoneHelper.php，因此您需要先解决这个问题。现在第二件事，您的文件实际上是空白的，除了 PHP 标记。

所以如果你想打电话说点什么，你可以使用 call(); 说（）；或者您可以只使用组合/快捷方式 message(); Tropo 脚本中的方法：

<?php
 message("Received office voice mail.", array("to" => "+14075550100"));
?>

现在回到最后一个问题，如何在 Tropo 应用程序上下文中获取发布的数据？好消息是，这很简单，我们实际上将这些作为全局变量在您的应用程序中，因此 numberToDial 查询字符串参数变为 $numberToDial，例如：

<?php
 message($msg, array("to" => "+".$numberToDial));
?>

我真的希望这会有所帮助，如果您仍然遇到麻烦，请联系我们的支持团队，或者在 freenode (#tropo) 上的 IRC 中找到我们。我的手柄是染色机，我经常在频道里潜伏；）

小心！
