cURL（PHP）無法正常工作的XML RPC post請求

Question

我想用cURL（PHP）將XML RPC api（http://www.zoho.com/creator/help/api/xml-rpc-api/xml-rpc-api-add-records.html）添加到zoho creator中。 我正在使用的代碼是：

<?php 
if(isset($_POST['Submit'])) { 
    // if data is posted 
    $urltopost = "https://creator.zoho.com/api/xml/write"; 
    $xml = '<ZohoCreator> 
    <applicationlist> 
     <application name=\'myapp\'> 
      <formlist> 
       <form name=\'my form\'> 
        <add> 
         <field name=\'fieldName\'> 
          <value>value</value> 
         </field> 
        </add> 
       </form> 
      </formlist> 
     </application> 
    </applicationlist> 
</ZohoCreator>'; 

$datatopost = array (
'authtoken' => '*******', //my authtoken 
'scope' => 'creatorapi', 
'XMLString' => $xml , 
'zc_ownername' => '*****'//the owner name 
); 
// post via curl 
$ch = curl_init ($urltopost); 
curl_setopt ($ch, CURLOPT_POST, true); 
curl_setopt ($ch, CURLOPT_POSTFIELDS, $datatopost); 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, true); 
$returndata = curl_exec ($ch); 
?> 

但是，這是行不通的。有沒有人有辦法解決嗎？謝謝。

使用http_build_query()在$datatopost，否則其張貼multipart/form-data

curl_setopt ($ch, CURLOPT_POSTFIELDS, http_build_query($datatopost));
