带cookie请求数据

经常会用到一些采集网上的资源，普通网站很好采，get_file_contents()/c_url(). 有的网站会有登陆后才能采集，需要带cookie请求获取（登陆网站相同方法），下面记录一下使用方法，供参考。

 <?PHP

 header('content-type:text/html;charset=utf8');

 define("COOKIE_PATH",dirname(__FILE__).'/cookie.txt');

 //获取COOKIE

 function curl_get_cookie($url){

     $ch = curl_init($url); //初始化

     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST , false);

     curl_setopt($ch, CURLOPT_URL, $url);

     curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0)');

     curl_setopt($ch, CURLOPT_HEADER, 0); //不返回header部分

     curl_setopt($ch, CURLOPT_RETURNTRANSFER, false); //返回字符串，而非直接输出

     curl_setopt($ch, CURLOPT_COOKIEJAR,  COOKIE_PATH); //存储cookies

     curl_exec($ch);

     curl_close($ch);

 }

 #带COOKIE请求

 function curl_cookie_request($url,$post){

     $ch = curl_init($url);

     curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

     curl_setopt($ch, CURLOPT_SSL_VERIFYHOST , false);

     curl_setopt($ch, CURLOPT_URL, $url);

     curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0)');

     curl_setopt($ch, CURLOPT_HEADER, 0);

     if($post) {

         curl_setopt($ch, CURLOPT_POST, 1);

         curl_setopt($ch, CURLOPT_POSTFIELDS, $post);

     }

     curl_setopt($ch, CURLOPT_HTTPHEADER, array(

         'Content-Type: application/json',

         'Content-Length: ' . strlen($post))

     );

     curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

     curl_setopt($ch, CURLOPT_COOKIEFILE, COOKIE_PATH); //使用上面获取的cookies

     $response = curl_exec($ch);

     curl_close($ch);

     return $response;

 }
