封装PHP的curl请求 支持POST和GET

方法

function http($url, $method="GET", $postfields = '', $headers = [], $debug = false, $timeout=60)
{
    $method = strtoupper($method);
    $ci = curl_init();
    curl_setopt($ci, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
    curl_setopt($ci, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows NT 6.2; WOW64; rv:34.0) Gecko/20100101 Firefox/34.0");
    curl_setopt($ci, CURLOPT_CONNECTTIMEOUT,$timeout); 
    curl_setopt($ci, CURLOPT_TIMEOUT, 7); 
    curl_setopt($ci, CURLOPT_RETURNTRANSFER, true);
    switch ($method) {
        case "POST":
            curl_setopt($ci, CURLOPT_POST, true);
            if (!empty($postfields)) {
                $tmpdatastr = is_array($postfields) ? http_build_query($postfields) : $postfields;
                curl_setopt($ci, CURLOPT_POSTFIELDS, $tmpdatastr);
            }
            break;
        default:
            curl_setopt($ci, CURLOPT_CUSTOMREQUEST, $method);
            break;
    }
    $ssl = preg_match('/^https:\/\//i',$url) ? TRUE : FALSE;
    curl_setopt($ci, CURLOPT_URL, $url);
    if($ssl){
        curl_setopt($ci, CURLOPT_SSL_VERIFYPEER, FALSE); 
        curl_setopt($ci, CURLOPT_SSL_VERIFYHOST, FALSE); 
    }
    if (ini_get('open_basedir') == '' && ini_get('safe_mode' == 'Off')) {
        curl_setopt($ci, CURLOPT_FOLLOWLOCATION, 1);
    }
    curl_setopt($ci, CURLOPT_MAXREDIRS, 2);
    curl_setopt($ci, CURLOPT_HTTPHEADER, $headers);
    curl_setopt($ci, CURLINFO_HEADER_OUT, true);
    $response = curl_exec($ci);
    $requestinfo = curl_getinfo($ci);
    $http_code = curl_getinfo($ci, CURLINFO_HTTP_CODE);
    curl_close($ci);
    return $response;
}
