Question

您好我有一个域名我想用cUrl解析，情况就是这样：

当我进入域http://register.metsad.ee/avalik/info_teatis.php?too_id=2942704201

时

它将我重定向到[register.metsad.ee/avalik/info_teatis.php?too_id=2942704201]

没有http：// www。我用来解析的代码是：

function get_data($url) {
        $ch = curl_init();
        $timeout = 5;
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
        curl_setopt($ch, CURLOPT_MAXREDIRS, 10);
        curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
        $data = curl_exec($ch);
        curl_close($ch);
        return $data;
    }
$src = 'http://register.metsad.ee/avalik/info_teatis.php?too_id=2942704201';

然后$c = get_data($src); echo $c; 为了重新获得我得到一个空白的白页。我也尝试使用Simple_Html_Dom解析器：

echo file_get_html($src)->plaintext;

但我仍然得到一个空白的白页。当我在没有http：//的情况下进行解析时，会出现错误

Warning: file_get_contents(register.metsad.ee/avalik/info_teatis.php?too_id=2942704201) [function.file-get-contents]: failed to open stream: Result too large in C:\xampp\htdocs\Trash\metsakontroll\system\c_simple_html_dom.php on line 70

cUrl仍然显示白屏，没效果。当我试图像这样的文件夹解析它时：

http://www.metsad.ee/register/avalik/info_teatis.php?too_id=2942704201然后服务器说未找到

我搜索了整个互联网= /任何想法如何通过cUrl或Simple_html_dom阅读该页面？

register.metsad.ee方面有某种保护。在设置User-Agent标头之前，Thay返回空响应。

呼叫失败（空响应）：

成功呼叫（返回HTML页面）：

所以你需要将下一行添加到：

curl_setopt($ch, So you need to add CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.1; WOW64; rv:12.0) Gecko/20100101 Firefox/12.0"); for example (or any other user agent string).

c没有http：// www的域名
