下面的代码非常简单。但是，当我执行它时，我总是从 Watson-Conversation 服务收到{"error":"Unsupported Media Type"}。请帮助告诉我问题出在哪里。

$curl = curl_init();

curl_setopt_array($curl, array(
    CURLOPT_POST => true,
    CURLOPT_URL => "https://watson-api-explorer.mybluemix.net/conversation/api/v1/workspaces/70b056e6-14a0-424f-9631-696272ce666e/message?version=2016-09-20",
    CURLOPT_USERPWD => "{MYUSERNAME}:{MYPASSWORD}",
    CURLOPT_POSTFIELDS => array('message' => '{ "input": { "text": "Hola" }, "alternate_intents": false }'),
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => true
));

$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);

if ($err)
{
    echo "cURL Error #:" . $err;
}
else
{
    echo $response;
}

非常感谢。
