带有URL的file_get_contents

Question

我正在使用Parse并尝试从网址获取图片并将其另存为ParseFile

我成功地将本地上传的图片保存为ParseFile。如何使用图片网址执行相同操作？

echo $_POST['imageURL']; // url to image
// successfully saves uploaded image
// $file = ParseFile::createFromData( file_get_contents( $_FILES['image']['tmp_name'] ), $_FILES['image']['name']  );

// trying to save image from URL
$file = ParseFile::createFromData( file_get_contents( $_POST['imageURL'] ), $_FILES['image']['name']  );

$file->save();

这是我得到的错误：

尝试此功能

function get_url_content($URL){
          $ch = curl_init();
          curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
          curl_setopt($ch, CURLOPT_URL, $URL);
          $data = curl_exec($ch);
          curl_close($ch);
          return $data;
      }

$file =  get_url_content('http://example.com/logo.jpg');
