curl类封装

记录一下自己整理的curl类封装

封装代码

function myCurl($url){
    $ch = curl_init();     // Curl 初始化  
    $timeout = 30;     // 超时时间:30s  
    $ua='Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36';    // 伪造抓取 UA  
	$ip = mt_rand(11, 191) . "." . mt_rand(0, 240) . "." . mt_rand(1, 240) . "." . mt_rand(1, 240);
    curl_setopt($ch, CURLOPT_URL, $url);              // 设置 Curl 目标  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);      // Curl 请求有返回的值  
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);     // 设置抓取超时时间  
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);        // 跟踪重定向  
    curl_setopt($ch, CURLOPT_ENCODING, "");    // 设置编码  
    curl_setopt($ch, CURLOPT_REFERER, $url);   // 伪造来源网址  
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-FORWARDED-FOR:'.$ip, 'CLIENT-IP:'.$ip));  //伪造IP  
    curl_setopt($ch, CURLOPT_USERAGENT, $ua);   // 伪造ua   
    curl_setopt($ch, CURLOPT_ENCODING, 'gzip'); // 取消gzip压缩  
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); // https请求 不验证证书和hosts  
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);  
	curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0); //强制协议为1.0
	curl_setopt($ch, CURLOPT_IPRESOLVE, CURL_IPRESOLVE_V4 ); //强制使用IPV4协议解析域名
    $content = curl_exec($ch);   
    curl_close($ch);    // 结束 Curl  
    return $content;    // 函数返回内容  
}
