Question

我正在尝试打开特定页面（https://www.yellowpages.com.au）我已经尝试过simplehtmldom 我也尝试过卷曲我尝试使用不同的标题并添加了证书我可以打开其他页面，而不能打开其他页面，并且想知道该站点如何阻止我的访问以及我可以做些什么。

$ch = curl_init();
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch,CURLOPT_URL,$url);
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.A.B.C Safari/525.13");


$certificate = "cacert-2019-01-23.pem";
curl_setopt($ch, CURLOPT_CAINFO, $certificate);
curl_setopt($ch, CURLOPT_CAPATH, $certificate);


$data = curl_exec($ch);
curl_close($ch);
echo $data;

URL https://www.yellowpages.com.au不为页面提供服务，它只是将您（通过HTTP Location Redirect重定向到实际为页面提供服务的另一个URL（具体来说为Location: http://www.yellowpages.com.au/dataprotection?path=/）。为了使用curl加载该URL，必须告诉curl遵循HTTP Location redirects，这可以通过CURLOPT_FOLLOWLOCATION完成，

除此之外，yellowpages.com.au会阻止缺少User-Agent标头的请求，libcurl没有设置默认的User-Agent标头，您可以使用CURLOPT_USERAGENT option进行设置，这是一个有效的示例：

<?php
$ch=curl_init('https://www.yellowpages.com.au');
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,true);
curl_setopt($ch,CURLOPT_USERAGENT,'libcurl/'.(curl_version()['version']).' PHP/'.PHP_VERSION);
curl_exec($ch);
curl_close($ch);

输出：
