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);
