CURL HTTP CODE 403

我得到curl http代码为403:

用户myuser被拒绝对对象缺损进行操作，原因如下:Create操作的权限设置不允许用户对安全对象进行操作

相同的代码与'HTTP'工作正常，现在它是'HTTPS'，所以我更新了代码，如添加curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);和curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);这些行，它给403作为HTTP code。谁能告诉我哪里错了?

$ch = curl_init(MY_BASE_URL);  
curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.A.B.C Safari/525.13');
curl_setopt($ch, CURLOPT_TIMEOUT, 30); 
curl_setopt($ch, CURLOPT_COOKIEFILE, MY_COOKIES);
curl_setopt($ch, CURLOPT_COOKIEJAR, MY_COOKIES);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/json; charset=utf-8","Accept:application/json, text/javascript, */*; q=0.01"));
curl_setopt($ch, CURLOPT_POST, true); 
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($myfields));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response=curl_exec($ch);
$code=curl_getinfo($ch, CURLINFO_HTTP_CODE);
if($code!=201)
{throw new Exception("Error creating defect: ".$response);}
else{echo 'Success';}
