1、伪造客户端IP地址，伪造访问referer:（一般情况下这就可以访问到数据了）curl_setopt($curl, CURLOPT_HTTPHEADER, ['X-FORWARDED-FOR:110.85.108.185', 'CLIENT-IP:110.85.108.185']); curl_setopt($curl, CURLOPT_REFERER, 'http://4dn.net/test.php');2、如是上面的还是不行，可能是别人抓到了真实IP，这时候我们就使用代{过}{滤}理访问# 详细方式 curl_setopt($curl, CURLOPT_PROXY, 'x.x.x.x'); //代{过}{滤}理服务器地址 curl_setopt($curl, CURLOPT_PROXYPORT, 80); //代{过}{滤}理服务器端口 //curl_setopt($curl, CURLOPT_PROXYUSERPWD, ':''); //http代{过}{滤}理认证帐号，username:password的格式 curl_setopt($curl, CURLOPT_PROXYTYPE, CURLPROXY_HTTP); //使用http代{过}{滤}理模式 # 简写方式 curl_setopt($curl, CURLOPT_PROXY, 'http://x.x.x.x:80');3、还有一种就是用浏览器可以访问，用curl不行。（对方检查了useragent，如果没有就认为是非法来源等验证了）$useragent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 '; $useragent.= '(KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'; curl_setopt($curl, CURLOPT_USERAGENT, $useragent);PHP完整Curl抓取数据函数：/** * 请求接口 * [url=home.php?mod=space&uid=718080]@access[/url] public * [url=home.php?mod=space&uid=952169]@Param[/url] string $url 请求地址 * @param array $data 提交参数 没有get 有post * [url=home.php?mod=space&uid=155549]@Return[/url] bean|array */ public function send($url='') { set_time_limit(0); $curl = curl_init(); curl_setopt($curl, CURLOPT_URL, $url); curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, 10); curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); curl_setopt($curl, CURLOPT_HTTPHEADER, ['X-FORWARDED-FOR:127.0.1.1', 'CLIENT-IP:127.0.1.1']); curl_setopt($curl, CURLOPT_REFERER, 'http://4dn.net/demo.php'); curl_setopt($curl, CURLOPT_PROXY, 'http://127.0.0.1:80'); $useragent = 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 '; $useragent.= '(KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'; curl_setopt($curl, CURLOPT_USERAGENT, $useragent); if(!empty($data) && is_array($data)){ curl_setopt($curl, CURLOPT_POST, true); curl_setopt($curl, CURLOPT_POSTFIELDS, $data); } $html = curl_exec($curl); if($error=curl_errno($curl)){ return false; } curl_close($curl); return $html; }
