Common Types Of Services

GET / POST

• More Service Oriented– Actions are performed on the same/similar endpoints

– Parameters or Body drive actions

– Tend to be more free for all in design

– Perform Read/Write operations

• Any data format supported– XML

– JSON

Examples From Amazon EC2 Servicehttps://ec2.amazonaws.com/?Action=AllocateAddress&AWSAccessKeyId=...

https://ec2.amazonaws.com/?Action=CreateKeyPair&KeyName=example-key-name&AWSAccessKeyId=...

Amazon Simple Queue Service

$url = 'http://queue.amazonaws.com/queue1';$params = array('Action'=>'SendMessage', 'MessageBody' => 'Your%20Message%20Text', 'AWSAccessKeyId'=>'0GS755xyzEXAMPLE', . . .);

$post_body = http_build_query($params);$context_params = array( 'http' => array( 'method' => 'POST', 'header' => 'Content-Type: application/x-www-form-urlencoded', 'content' => $post_body ));$file_context = stream_context_create($context_params);

$results = file_get_contents($url, false, $file_context);var_dump($results);

RESTful

• Generally follow REST guidelines

• Read-only data using HTTP GET

• URL path typically does not refer to resource

• Parameters influence results

Yahoo Image Search

http://search.yahooapis.com/ImageSearchService/V1/imageSearch?appid=YahooDemo&query=PHP+elephant&output=json

{"ResultSet":{"totalResultsAvailable":"561","totalResultsReturned":10,"firstResultPosition":1,"Result":[{"Title":"php_elephant.jpg","Summary":"php_elephant.jpg","Url":"http:\/\/vizzed.com\/VizzedBoardFiles\/upload\/php_elephant.jpg","ClickUrl":"http:\/\/vizzed.com\/VizzedBoardFiles\/upload\/php_elephant.jpg","RefererUrl":"http:\/\/vizzed.com\/VizzedBoardFiles\/upload","FileSize":7065,"FileFormat":"jpeg","Height":"96","Width":"150","Thumbnail":{"Url":"http:\/\/re3.yt-thm-a01.yimg.com\/image\/25\/m1\/2070796738","Height":"80","Width":"125"}} . . .

Representational State Transfer: REST

• Endpoints are resource identifiers– A resource is any named item

– Resources are identified by URLs

• Architectural style not a standard

• Builds upon standards– HTTP

– URLS

– Mime types

• HTTP methods determine action

• Google APIs are good examples– Calendar

– Spreadsheet

– Notebook

XML-RPC

• XML-based Remote Procedure Call

• Function call is marshaled

• Data structure defines method, types and values

• Parameters and return values are typed

• Defines how the messages is to be transported– HTTP POST

– Required HTTP Headers

• More Tightly Coupled

• Predecessor to SOAP

13

XML-RPC Request

HTTP POST: http://www.upcdatabase.com/rpc

lookupUPC 021000013425

14

upc 021000013425 description SUPER MAC & CHEESE SPONGE BO * size 5.5 oz

XML-RPC Response

15

JSON-RPC

• Comparable to XML-RPC though using JSON

• In addition to method and parameters, JSON-RPC includes an id property to map requests and responses

• Defines one-way communications (notifications)

• No specific transport protocol required

• HTTP POST most common transport

16

JSON-RPC Request

HTTP POST:http://www.raboof.com/Projects/Jayrock/Demo.ashx

Content-type: application/json

{"method":"total","params":{"values":[1,2,3]},"id":55}

$data = array("method"=>"total", "params"=>array("values"=>array(1,2,3)), "id" => 55);echo json_encode($data)."\n";$json = json_encode($data)

17

http://www.raboof.com/Projects/Jayrock/Demo.ashxhttp://www.raboof.com/Projects/Jayrock/Demo.ashx

JSON-RPC Response

{"id":55,"result":6}

$objResult = json_decode($results); echo $obResult->result."\n";

18

SOAP

• SOAP stands for ABSOLUTELY NOTHING!

• Can be RPC or Message based

• Strong data typing

• Designed for interoperability

• Can be simple to use

• Allows for advanced communications– Standard security mechanisms

– Message delivery guarantee

– Additional out of band information

– Addressing and callback capabilities

Deciding Upon A Service

With All The Different Types Of Services, How Do You Decide

What To Use?

?22

Intended Audience

• Exposing To The Masses

• Internal Developers

• Business Partners

• Multiple Audiences

23

Security Implications

• Do you need to protect your data?

• Do users need to be authenticated?

• To what level do you need protection?

• Are multiple parties involved?

• Does the data pass through multiple systems?

• Do you need granularity?

24

What Is The Purpose?

• Reduce system maintenance?

• Expose existing logic as services?

• Expose logic from legacy systems?

• Aggregate functionality?

25

Any Curveballs?

• Two-phase commits

• Asynchronous Messaging

• Legacy System Protocols

• Multi-System Involvement

Generating The WSDL

• Integrated Generators– Services_Webservices

• http://pear.php.net/package/Services_Webservice

– PRADO

• http://pradosoft.com/demos/quickstart/?page=Services.SoapService

– WSO2 WSF/PHP (http://wso2.org/projects/wsf/php)

Services_Webservice WSDL Generation

include_once('Services/Webservice.php'); class myService extends Services_Webservice { /** * Says "Hello!" * * @param int * @return string */ public function hello($i ) { //create some logic here return 'myString'; }

79

Serving Up The WSDL

Server Script: myserv.php

/* Helper functions here */$soapSrv = new SoapServer('helloworld.wsdl');

/* Register functions */$soapSrv->handle();

Using the SoapClient:$soapClient = new SoapClient( 'http://localhost/myserv.php?wsdl');

80

Handling Requests

• The typical method to process a SOAP request– $soapServer->handle();

• Request may be passed to handler– $soapServer->handle($request);

• Passing in the request can be handy– You can be guaranteed of the same request while debugging

– Debugging can be performed via CLI

– Requests can be modified prior to being processed

81

Handling Requests: Debugging

/* create the initial request to be re-used */$request = file_get_contents("php://input");file_save_contents('debugging.xml', $request);

/* retrieve saved request on subsequent calls$request = file_get_contents('debugging.xml');*/

$server = new SoapServer($wsdl);/* Setup function handlers */$server->handle($request);

Service Component Architecture (SCA)

• Project by the Open Service Oriented Architecture (OSOA) collaboration - http://www.osoa.org/display/Main/Home

• http://www.osoa.org/display/PHP/SOA+PHP+Homepage

• Combined with the SDO extension

• Pecl repository: http://pecl.php.net/package/SCA_SDO

• Allows the developer to concentrate on the business logic rather than how it is all connected together
