RPC Service

+ +

+RPC Service stands for "Remote Procedure Call" Service and is a common name used to identify a service that exposes an interface that can be called by remote programs in order to execute a procedure. +An RPC Service tipically exposes one or more APIs (Application programming interface), permitting remote clients to make requests to the available methods and receive a proper response. +The interface itself is not bound to a specific programming language, but uses a standard data exchange protocol (tipically xml or json). +PRADO provides TRpcService that makes developing a RPC server application an extremely easy task. +

+ +

+To use TRpcService, configure it in the application specification like following: +

+ + + + + + + + +

+The example specifies a RPC service provider named stockquote which implements the getPrice RPC method in the provider class StockQuote, +

+ +class StockQuote +{ + /** + * @param string $symbol the symbol of the stock + * @return float the stock price + * @soapmethod + */ + public function getPrice($symbol) + { + ....return stock price for $symbol + } + + /** + * Register the available methods + * @return the list of implemented methods + */ + public function registerMethods() + { + return array( + 'getPrice' => array('method' => array($this, 'getPrice')), + ); + } + +} + + +

+PRADO already bundles two common protocols: TXmlRpcService and TJsonRpcService: requests made by clients using one of these protocol will be automatically resolved and will call the user-specified APIs. +

+ +
Note: +TXmlRpcService is based on PHP XML-RPC extension and thus requires the extension to be installed. +
+ +

+With the above simple code, we already finish a simple RPC service that allows other applications to query the price of a specific stock. A client needs to know the exact url of the service, the name of the method and the list of parameters needed by the method. +

+ +// Assuming we're using the json-rpc php library from http://jsonrpcphp.org/ + +require_once 'jsonRPCClient.php'; +$client=new jsonRPCClient('http://path/to/index.php?rpc=stockquote'); +echo $client->getPrice('IBM'); + + + -- cgit v1.2.3
