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;
}
