file_get_contents不适用于某些域

许多站点(不仅仅是停放的域)使用某种机制来阻止没有有效浏览器标头的基本请求。

尝试使用流上下文来发送所需的标头,就像这样的浏览器

$url = "http://buythisdomain.com/"
$context = stream_context_create(array(
    'http' => array(
        'method' => "GET",
        'header' =>
            "Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8\r\n" .
            "Accept-Language: en-US,en;q=0.8\r\n".
            "Keep-Alive: timeout=3, max=10\r\n",
            "Connection: keep-alive",
        'user_agent' => "User-Agent: Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.11 (KHTML, like Gecko) Chrome/17.0.963.66 Safari/535.11",
        "ignore_errors" => true,
        "timeout" => 3
    )
));
file_get_contents($url, false, $context);
