php – 是否可以使用cURL使用POST流上传文件？

// URL on which we have to post data
$url = "http://localhost/tutorials/post_action.php";
// Any other field you might want to catch
$post_data['name'] = "khan";
// File you want to upload/post
$post_data['file'] = "@c:/logs.log";

// Initialize cURL
$ch = curl_init();
// Set URL on which you want to post the Form and/or data
curl_setopt($ch,CURLOPT_URL,$url);
// Data+Files to be posted
curl_setopt($ch,CURLOPT_POSTFIELDS,$post_data);
// Pass TRUE or 1 if you want to wait for and catch the response against the request made
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
// For Debug mode; shows up any error encountered during the operation
curl_setopt($ch,CURLOPT_VERBOSE,1);
// Execute the request
$response = curl_exec($ch);

// Just for debug: to see response
echo $response;

除了该默认方法之外,无法使用cURL使用POST方法流上传文件.
