SOA with C, C++, PHP and more
3 likes3,788 views
The document discusses the implementation of Service-Oriented Architecture (SOA) using various programming languages such as C, C++, and PHP. It highlights the advantages of each language for building web services, including performance and portability, while providing examples of secure service implementations and client interactions in PHP and C++. The text also mentions the capabilities of specific frameworks and tools that facilitate SOA integration across heterogeneous environments.
SOA with C, C++, PHP and more
- 1. SOA with C, C++, PHP … Samisa Abeysinghe Director, Engineering WSO2, Inc
- 2. SOA is about Architectural Design And We need implementation techniques & tools to build it
- 3. Language of your Choice You should have freedom to choose You might also have reasons to choose
- 4. Why C? Because it is the most portable And bunch of other reasons like Many interesting applications written in C httpd, PHP, Ruby, MySQL
- 5. Why C++? Widely used (and some legacy) Financial, Banking, Telco, DBMS, Embedded And like C it offers: Performance, Flexibility, Control
- 6. Why PHP? Installed on over 20 million websites and 1 million web servers http://www.php.net/usage.php
- 7. Chances Your other application (legacy or green-field) can be C, C++, PHP or the like Can we get them on the SOA?
- 8. SOA in a Heterogeneous World
- 9. Expectations Tooling for WSDL Security Interoperability Binary Attachments Reliability
- 11. PHP Web Services Frameworks Package Written in WSDL Security Attachments Reliability PHP5 SOAP Ext C Partial No No No NuSOAP PHP Yes No No No SCA with PHP(IBM) PHP Yes No No No WSO2 WSF/PHP C Yes Yes Yes Yes
- 12. Framework that improves PHP user’s ability to provide and consume Web services Capable of dealing with secure and relabel messaging even with binary data, the only PHP software package to offer those features The framework is inter-operable with non-PHP imple- mentations, allowing it to be integrated with enterprise applications seamlessly
- 14. PHP Example – Secure Service 1. function echoFunction($inMessage) { 2. $returnMessage = new WSMessage($inMessage->str); 3. return $returnMessage; 4. } 5. 6. $pub_key = ws_get_cert_from_file("../keys/alice_cert.cert"); 7. $pvt_key = ws_get_key_from_file("../keys/bob_key.pem"); 8. 9. $operations = array("echoString" => "echoFunction"); 10. 11. $sec_array = array("encrypt" => TRUE, "algorithmSuite" => "Basic256Rsa15", 12. "securityTokenReference" => "IssuerSerial"); 13. 14. $actions = array("http://php.axis2.org/samples/echoString" => "echoString"); 15. 16. $policy = new WSPolicy(array("security"=>$sec_array)); 17. $sec_token = new WSSecurityToken(array("privateKey" => $pvt_key, 18. "receiverCertificate" =>$pub_key)); 19. 20. $service = new WSService(array("actions" => $actions, 21. "operations" => $operations, 22. "policy" => $policy, "securityToken" => $sec_token)); 23. 24. $service->reply();
- 15. PHP Example – Secure Client 1.$rec_cert = ws_get_cert_from_file("../keys/bob_cert.cert"); 2.$pvt_key = ws_get_key_from_file("../keys/alice_key.pem"); 3. 4.$reqMessage = new WSMessage($reqPayloadString, array("to"=> 5. "http://localhost/samples/security/encryption/encrypt_service.php", 6. "action" => "http://php.axis2.org/samples/echoString")); 7. 8.$sec_array = array("encrypt"=>TRUE, "algorithmSuite" => "Basic256Rsa15", 9. "securityTokenReference" => "IssuerSerial"); 10. 11.$policy = new WSPolicy(array("security"=>$sec_array)); 12.$sec_token = new WSSecurityToken(array("privateKey" => $pvt_key, 13. "receiverCertificate" => $rec_cert)); 14. 15.$client = new WSClient(array("useWSA" => TRUE, "policy" => $policy, 16. "securityToken" => $sec_token)); 17. 18.$resMessage = $client->request($reqMessage); 19. 20.printf("Response = %s n", $resMessage->str);

- 18. Designed for embedding within C or C++ soft- ware stacks to enable Web services All-in-one solution for the building and deploy- ing of Web services Widest range of WS-* specifications imple- mentations WS-Addressing, WS-Policy, WS-Security, WS- SecurityPolicy, WS-Reliable Messaging, MTOM and WS-eventing
- 19. C++ Example - Service 1.#include <ServiceSkeleton.h> 2. 3.using namespace wso2wsf; 4. 5.class Echo: public ServiceSkeleton 6.{ 7. public: 8. WSF_EXTERN WSF_CALL Echo(){}; 9. 10. OMElement* WSF_CALL invoke(OMElement *message, MessageContext *msgCtx); 11. 12. OMElement* WSF_CALL onFault(OMElement *message); 13. 14. void WSF_CALL init(){}; 15.}; 1.OMElement* Echo::invoke(OMElement *element, MessageContext *msgCtx) 2.{ 3.

OMElement *textElement = new OMElement("messsage"); 7. echoElement->addChild(textElement); 8. textElement->setText("Hello World"); 9. return echoElement; 10.}

C++ Example - Client 1.ServiceClient serviceClient(client_repo, end_point); 2. 3.OMNamespace * ns = new OMNamespace("http://ws.apache.org/rampart/c/samples", "ns1"); 4.OMElement * payload = new OMElement(NULL, "echoIn", ns); 5.OMElement * child = new OMElement(payload, "message", NULL); 6.child->setText("Hello Service!"); 7. 8.try 9.{ 10. OMElement* response = serviceClient.request(payload, 11. "http://example.com/ws/2004/09/policy/Test/EchoRequest"); 12. if (response) 13. { 14. cout << endl << "Response: " << response << endl; 15. } 16.} 17.catch (AxisFault & e) 18.{ 19. if (serviceClient.getLastSOAPFault()) 20. { 21. cout << endl << "Fault: " << serviceClient.getLastSOAPFault() << endl; 22. } 23. else 24. { 25. cout << endl << "Error: " << e << endl; 26. } 27.} 28.delete payload;

- 23. Web Services are Still Faster For secure services 10K messages C implementation x10 – x15 times faster than Java 100k messages C implementation x6 – x8 times faster than Java
- 24. WSF/C++ Features SOAP 1.1 and SOAP 1.2 WS-Addressing 1.0 submission MTOM and SwA Support for caching large attachments WS-Security Base security standards mean that messages can be protected using Encryption, Authentication and Signature Including WS-SecureConversation and WS-Trust WSDL2CPP Code Generation tool Supports generating client stubs, service skeletons, build scripts and deployment scripts
- 25. WSF/C++ Features WS-Policy and WS-Security Policy Enables using industry standard XML to configure security SSL Enabled Transport Layer WS-Reliable Messaging 1.0, 1.1 and WS-RMPolicy Enables reliability between platforms including message resending, duplicate detec- tion and persistence Full REST support (GET, PUT, DELETE, POST) with custom URI Mapping Enables mapping a REST API easily and naturally Useful tools Tcpmon wsclient
