我正在尝试cURL一个远程站点，导致403 Forbidden错误。在同一台服务器上，我可以通过终端运行以下两个命令。第一个失败，而第二个工作。如何使我的PHP代码与第二个终端命令相匹配？
此终端命令不会返回任何结果。
curl http://www.barneys.com
该终端命令产生正确的结果（页面的HTML）
curl -L http://www.barneys.com
我的PHP代码：
$ch = curl_init('http://www.barneys.com');
$http_headers = array(
'User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:40.0)' . 'Gecko/20100101 Firefox/40.0',
'Accept: */*',
'X-Requested-With: XMLHttpRequest',
'Referer: http://www.barneys.com', # IMPORTANT
'Accept-Language: pt-BR,en-US;q=0.7,en;q=0.3',
);
curl_setopt($ch, CURLOPT_HTTPHEADER, $http_headers);
curl_setopt($ch, CURLOPT_USERAGENT,'Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.13) Gecko/20080311 Firefox/2.0.0.13');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_REFERER, 'http://www.barneys.com');
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 0);
curl_setopt($ch, CURLOPT_TIMEOUT, 60);
$response = curl_exec($ch);
$redirectURL = curl_getinfo($ch,CURLINFO_EFFECTIVE_URL);
curl_close($ch);
echo $response;
编辑：以下是通过PHP:的cURL请求的日志

php cURL请求中不包含请求头。要解决此问题，请在设置CURLOPT_HTTPHEADER选项之前添加以下行：
curl_setopt($ch, CURLOPT_HEADER, true);
来自PHP curl文档：
CURLOPT_HEADER TRUE，将标头包含在输出中。
此外，如果在url中添加尾部斜杠，则不需要通过cURL重建url。您的许多代码似乎是不必要的。下面是一个精简的工作示例：
<?php
$ch = curl_init('http://www.barneys.com/');
$http_headers = array(
'User-Agent: Junk', // Any User-Agent will do here
);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $http_headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
echo $response;
