在ckfinder上选择后，如何将域名网址添加到上传文件的网址中

我正在ckfinderCKEditor 4上进行设置。当我使用“浏览服务器”按钮选择图像时，图像的URL为：/ckfinder/userfiles/images/image.png。

但是它应该是完整的网址，例如：http://example.com/ckfinder/userfiles/images/image.png。

我的ckeditor/config.js档案：

CKEDITOR.replace( 'content_en', {
    filebrowserBrowseUrl: 
    './assets/app/js/ckfinder/ckfinder.html',
filebrowserImageBrowseUrl: 
    './assets/app/js/ckfinder/ckfinder.html?type=Images',
filebrowserUploadUrl: 
    './assets/app/js/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Files',
filebrowserImageUploadUrl: 
    './assets/app/js/ckfinder/core/connector/php/connector.php?command=QuickUpload&type=Images'
});

我的config.php档案在ckfinder：

$config['backends'][] = array(
    'name'         => 'default',
    'adapter'      => 'local',
    'baseUrl'      => '/ckfinder/userfiles/',
//  'root'         => '', // Can be used to explicitly set the  CKFinder user files directory.
    'chmodFiles'   => 0777,
    'chmodFolders' => 0755,
    'filesystemEncoding' => 'UTF-8',
);
