在前面利用 QQWry.Dat 实现 IP 地址高效检索（PHP） 和 利用 QQWry.Dat 实现 IP 地址高效检索（PHP 共享内存版）的基础上，我们只需再写一点儿代码，就可以实现一个 PHP XML-RPC 的查询接口了。
下面是有用共享内存版实现的程序：
<?php
include('xmlrpc.inc.php');
include('xmlrpcs.inc.php');
include('iplocation.inc.php');
function iplocation_xmlrpc($params) {
$ipval = $params->getParam(0);
$ip = $ipval->scalarval();
$iplocation = & IpLocation::getInstance();
$location = $iplocation->getlocation($ip);
if (function_exists('iconv')) {
$location['country'] = iconv("GBK", "UTF-8", $location['country']);
$location['area'] = iconv("GBK", "UTF-8", $location['area']);
}
else if (function_exists('mb_convert_encoding')) {
$location['country'] = mb_convert_encoding($location['country'], "UTF-8", "GBK");
$location['area'] = mb_convert_encoding($location['area'], "UTF-8", "GBK");
}
else {
return new xmlrpcresp(0, $xmlrpcerruser, "Can't convert the result to the correct encode.");
}
return new xmlrpcresp(new xmlrpcval(array(
"ip" => new xmlrpcval($location['ip'], "string"),
"beginip" => new xmlrpcval($location['beginip'], "string"),
"endip" => new xmlrpcval($location['endip'], "string"),
"country" => new xmlrpcval($location['country'], "string"),
"area" => new xmlrpcval($location['area'], 'string')), "struct"));
}
new xmlrpc_server(array('iplocation' =>
array('function' => 'iplocation_xmlrpc',
'signature' => array(array('struct', 'string')),
'docstring' => 'Return the location of the ip or domain name.'))
);
?> |
有了这个 XML-RPC 服务器，我们就可以在任何程序中去调用它了
