Question

我需要解析网站http://klassprof.org/。但是有Cloudflare反DDOS保护。我如何解决这个问题？ 我从Chrome浏览器复制了Cookie并将其设置在我的卷曲功能中，但它没有帮助。在这里我的功能：

function get_web_page($url) 
{ 
    $uagent = "Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.14"; 
    $ch = curl_init($url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
    //curl_setopt($ch, CURLOPT_PROXY, "46.242.85.129:8081"); 
    curl_setopt($ch, CURLOPT_USERAGENT, $uagent); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 120);   
    curl_setopt($ch, CURLOPT_MAXREDIRS, 10); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
    curl_setopt($ch, CURLOPT_COOKIE, "PHPSESSID=f9sofurv85om9qq91rpt3rgkh2;__cfduid=db1ddd834ca4ec4c1ebdff85f5b00f7e51492411567;cf_clearance=33fc7099c3c9c000dc60be8e546e09182bb9df68-1492411571-1800"); 
    //curl_setopt($ch, CURLOPT_COOKIEFILE,"d://coo.txt"); 
    $content = curl_exec($ch); 
    $err  = curl_errno($ch); 
    $errmsg = curl_error($ch); 
    $header = curl_getinfo($ch); 
    /*foreach($header as $key=>$value){ 
     echo $key.' -- > '.$value.'<br>'; 
    }*/ 
    curl_close($ch); 
    $header['errno'] = $err; 
    $header['errmsg'] = $errmsg; 
    $header['content'] = $content; 
    return $header; 
}

这工作：

function get_web_page($url){ 
    $uagent = "Opera/9.80 (Windows NT 6.1; WOW64) Presto/2.12.388 Version/12.14"; 
    $ch = curl_init($url); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
    //curl_setopt($ch, CURLOPT_PROXY, "46.242.85.129:8081"); 
    curl_setopt($ch, CURLOPT_USERAGENT, $uagent); 
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 120); 
    curl_setopt($ch, CURLOPT_TIMEOUT, 120); 
    curl_setopt($ch, CURLOPT_MAXREDIRS, 10); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE); 
    curl_setopt($ch,CURLOPT_ENCODING , "gzip"); 
    curl_setopt($ch, CURLOPT_HTTPHEADER, [ 
     'Accept:text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8', 
     'Accept-Encoding:gzip, deflate, sdch', 
     'Accept-Language:en-US,en;q=0.8,vi;q=0.6,ar;q=0.4,zh-CN;q=0.2,zh;q=0.2,de;q=0.2', 
     'Cache-Control:max-age=0', 
     'Connection:keep-alive', 
     'Cookie: __cfduid=d8994a468f6c05474b2624a246b28e1a91492417194; PHPSESSID=pcfpgp75jhusb216a762p7ofe7; cf_clearance=4e7defa3af691c33e6c567fff872c8e58aa1583a-1492423220-1800', 
     'Host:klassprof.org', 
     'Upgrade-Insecure-Requests:1', 
     'User-Agent:Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/51.0.2704.79 Safari/537.36' 
    ]); 
    $content = curl_exec($ch); 
    $err  = curl_errno($ch); 
    $errmsg = curl_error($ch); 
    $header = curl_getinfo($ch); 
    /*foreach($header as $key=>$value){ 
      echo $key.' -- > '.$value.'<br>'; 
    }*/ 
    curl_close($ch); 
    $header['errno'] = $err; 
    $header['errmsg'] = $errmsg; 
    $header['content'] = $content; 
    return $header; 
    } 

    echo get_web_page('http://klassprof.org/')['content'];
