//上传页面代码
$url = "http://192.168.1.100/upload.php?lang=cn"; #可以get传相应参数
$file = $path.'/'. $Icon; //要上传的文件
$fields['f'] = '@'.$file;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url );
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, 1 );
curl_setopt($ch, CURLOPT_POSTFIELDS, $fields );
curl_exec( $ch );
if ($error = curl_error($ch) ) {
die($error);
}
curl_close($ch);
//接收图片资源
date_default_timezone_set('Asia/Shanghai'); //设置时区
$ip = '';

}
preg_match("/[\d\.]{7,15}/", $ip, $ipmatches);
$ip = $ipmatches[0] ? $ipmatches[0] : 'unknown';
//驗證請求IP,设置白名单
$date = date("[Y-m-d H:i:s]");
$allowip = array('192.168.1.100');
if(!in_array($ip,$allowip)){
$ipVal = "{$date}{$ip}\n";
file_put_contents('upload_ip.log', $ipVal, FILE_APPEN);
die(-1);
}
//接收get传参
$lang = isset($_REQUEST['lang']) ? $_REQUEST['lang'] : 'CN';
$uploaddir = "/data/cdncache/res/gifts/{$lang}/";
$uploadfile = $uploaddir . $_FILES['f']['name'];
if (move_uploaded_file($_FILES['f']['tmp_name'], $uploadfile)) #保存图片成功
