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，我如何引用已发布的xml来获取numberToDial和msg？

答案 0 :(得分：3)
这里似乎有一些混乱/问题，所以我会尽力为你解决这些问题。我想要讨论的第一件事是会话API的XML帖子是完全可选的，它只是您提交“令牌请求”的一种方式。开始拨打电话。如果你在解决这个问题时遇到了问题，那就让我们跳过它，然后尝试一下“飞机”。 HTTP GET直接从浏览器直到你最舒服：
api.tropo.com/1.0/sessions?action=create&token=123456&customerName=Kent&numberToDial=4075551212&msg=XML%20Test
现在进入脚本本身，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。首先你拼错了应用程序startURL，我几乎可以肯定你的意思是ExternalPhoneHelper.php，但是你输入了ExterMalPhoneHelper.php，所以你需要先修复它。现在第二件事，你的文件实际上是空白的，但PHP标签除外。
所以如果你想打个电话并说些什么就可以使用call（）;有发言权（）;或者您可以使用组合/快捷方式消息（）; Tropo脚本中的方法：
<?php
message("Received office voice mail.", array("to" => "+14075550100"));
?>
现在回答最后一个问题，如何在Tropo应用程序上下文中获取发布的数据？好吧，好消息是这很简单，我们实际上将这些作为全局变量放在你的应用程序中，所以numberToDial查询字符串参数变成$ numberToDial，例如：
<?php
message($msg, array("to" => "+".$numberToDial));
?>
我真的希望这会有所帮助，如果你仍然发现自己遇到了麻烦，请到我们的支持团队，或者在freenode（#tropo）的IRC找到我们。我的处理方式是dyer，而且我经常潜伏在通道中;）
小心！
