5. Encapsulate the client request method and inherit the HessianApi class

{
// If you call the hessian service of the java platform, you need to specify the type of parameters you pass, especially Integers and strings.
$price = (int) $price;

$result = $this->getHandler()->goodsInfomationApi( $title, $price);
$ this->resultLog( 'getGoodsInfomation' , 'Access interface, but the interface is not logically verified.');
// IDE: Zend Studio 9.0
// IDE Extension: Toggle Vrapper
?>



6. Modify index.php to request the server interface

Copy code

The code is as follows:

// Request the interface to obtain data
$goods = new Goods( HESSIAN_URL );

//Set product title and price.
$title = 'Beijing Mobile Recharge Platform';
$price = '50';

//Request Hessian protocol
$goodsInfo = $goods->getGoodsInfomation( (string) $title , (int) $price );

echo ( $goodsInfo );
