需要将xml字符串发送到第三方api，使用重力表单

Question

我需要有一个gform提交后，作为xmldata第三方api。

数据需要发布到的Url：

https://www.3rdparty.com/api/lead/insertRecord?apiauthkey=yourapikey&secretkey=yoursecretkey&xmlData=yourxmldata

所需的XML格式：

<crcloud>
  <lead>
    <type>Client</type>
    <firstname>Scott</firstname>
    <lastname>James</lastname>
    <client_assigned_to>Bill Smith</client_assigned_to>
  </lead>
</crcloud>

我写了一个curl函数，但我在发布时收到一个解析错误。我已经验证了xml，它是正确的。我还可以将打印出来的xml数据直接粘贴到我的url后面，并获得我想要的结果。

<?php

add_action("gform_after_submission", "set_post_content", 10, 2);
function set_post_content($entry, $form){

function post_to_url($url, $post) {
$fields = '';
foreach($post as $key => $value) {
$fields .= $key . '=' . $value . '&';
}
rtrim($fields, '&');

$url = 'https://www.3rdparty.com/api/lead/insertRecord?apiauthkey=yourapikey&secretkey=yoursecretkey&xmlData=yourxmldata';

$post = curl_init();

curl_setopt($post, CURLOPT_URL, $url);
curl_setopt($post, CURLOPT_POST, count($data));
curl_setopt($post, CURLOPT_POSTFIELDS, $fields);
curl_setopt($post, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($post, CURLOPT_SSL_VERIFYPEER, 0);

$result = curl_exec($post);
echo $post; //Resource id #*** currently
echo $result; //False 4404 XML parsing error currently
curl_close($post);
}

if($form["id"] == 2){//sign up now

$data = array(
"type" =>     $entry["31"],      
"firstname" =>     $entry["3"], 
"lastname" =>     $entry["4"], 
"client_assigned_to" =>     $entry["34"]);       

$xml = new SimpleXMLElement('<crcloud/>');
$lead = $xml->addchild('lead');
$data = array_flip($data);
array_walk_recursive($data, array ($xml, 'addChild'));

print $xml->asXML();

post_to_url($url, $xml);

}
}
?>

同时添加这个curl标头，让服务器知道您正在向他们发送xml

curl_setopt($post, CURLOPT_HTTPHEADER, 
    array('Content-Type: application/xml')
);

在任何情况下，如果您没有发送XML数据(在您的示例中，我没有看到您发送xml)。这就是它：

$post_data = "<crcloud>
  <lead>
    <type>$client</type>
    <firstname>$user</firstname>
    <lastname>$name</lastname>
    <client_assigned_to>$assigned</client_assigned_to>
  </lead>
</crcloud>";

curl_setopt($post, CURLOPT_POSTFIELDS, $post_data);
