客户端代码示例

require_once('../lib/nusoap.php');
$proxyhost = isset($_POST['proxyhost']) ? $_POST['proxyhost'] : '';
$proxyport = isset($_POST['proxyport']) ? $_POST['proxyport'] : '';
$proxyusername = isset($_POST['proxyusername']) ? $_POST['proxyusername'] : '';
$proxypassword = isset($_POST['proxypassword']) ? $_POST['proxypassword'] : '';
echo 'You must set your username and password in the source';
exit();
$client = new nusoap_client("http://staging.mappoint.net/standard-30/mappoint.wsdl", 'wsdl',
						$proxyhost, $proxyport, $proxyusername, $proxypassword);
$err = $client->getError();
