Question

嗨，我正在尝试使用CURL从以下网站获取网页，这是我的代码：我的带有CURL设置的PHP文件

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300); 
curl_setopt($ch, CURLOPT_TIMEOUT, 300); //timeout in seconds
$resultcurl = curl_exec($ch);
$curl_errno = curl_errno($ch);
$curl_error = curl_error($ch);
curl_close($ch);

在通过Stackoverflow浏览了CURL之后，我得到了一条建议如下的帖子

$header = get_headers('https://www.websitedomain.com/somepage');
echo '<pre>';
print_r($header);
echo '</pre>';

然后我得到了：

Array
(

    [1] => Cache-Control: no-cache, must-revalidate
    [2] => Content-Type: text/html; charset=UTF-8

)

内容长度始终显示为“ 10”，当我直接通过浏览器访问该页面时，它会起作用！有人可以帮忙!!吗？

Answer 1

HTTP / 1.1 301永久移动

您将获得重定向。您需要遵循它，哪些浏览器会自动执行，但是默认情况下不会启用PHP的cURL库。您可以使用以下方法进行更改：

curl_setopt($curl, CURLOPT_FOLLOWLOCATION, true);

卷曲GET响应为空结果
