README
PHP implementation of SOAP 1.1 and 1.2 server specifications.
Strengths:
- Pure PHP, no dependencies on
ext-soap
- Extensible (JMS event listeners support)
- PSR-7 HTTP messaging
- PSR-15 HTTP server handlers
- No WSDL/XSD parsing on production
- IDE type hinting support
Only document/literal style is supported and the webservice should follow the WS-I guidelines.
There are no plans to support the deprecated rpc and encoded styles. Webservices not following the WS-I specifications might work, but they are officially not supported.
Demo
goetas-webservices/soap-server-demo is a demo project that shows how to produce a SOAP server in a generic PHP web application.
Installation
The recommended way to install goetas-webservices / soap-server is using Composer:
Add this packages to your composer.json
file.
{
"require": {
"goetas-webservices/soap-server": "^0.1",
},
"require-dev": {
"goetas-webservices/wsdl2php": "^0.5.1",
},
}
How to
To improve performance, this library is based on the concept that all the SOAP/WSDL metadata has to be compiled into PHP compatible metadata (in reality is a big plain PHP array, so is really fast).
To do this we have to define a configuration file (in this case called config.yml
) that
holds some important information.
Here is an example:
# config.yml soap_server: namespaces: 'http://www.example.org/test/': 'TestNs/MyApp' destinations_php: 'TestNs/MyApp': soap/src destinations_jms: 'TestNs/MyApp': soap/metadata aliases: 'http://www.example.org/test/': MyCustomXSDType: 'MyCustomMappedPHPType' metadata: 'test.wsdl': ~
This file has some important sections:
WSDL Specific
metadata
specifies where are placed WSDL files that will be used to generate al the required PHP metadata.
XML/XSD Specific
-
namespaces
(required) defines the mapping between XML namespaces and PHP namespaces. (in the example we have thehttp://www.example.org/test/
XML namespace mapped toTestNs\MyApp
) -
destinations_php
(required) specifies the directory where to save the PHP classes that belongs toTestNs\MyApp
PHP namespace. (in this exampleTestNs\MyApp
classes will ne saved intosoap/src
directory. -
destinations_jms
(required) specifies the directory where to save JMS Serializer metadata files that belongs toTestNs\MyApp
PHP namespace. (in this exampleTestNs\MyApp
metadata will ne saved intosoap/metadata
directory. -
aliases
(optional) specifies some mappings that are handled by custom JMS serializer handlers. Allows to specify to do not generate metadata for some XML types, and assign them directly a PHP class. For that PHP class is necessary to create a custom JMS serialize/deserialize handler.
Metadata generation
In order to be able to use the SOAP server we have to generate some metadata and PHP classes.
To do it we can run:
bin/soap-server generate \ tests/config.yml \ --dest-class=GlobalWeather/Container/SoapServerContainer \ soap/src-gw/Container
bin/soap-server generate
is the command we are runningtests/config.yml
is a path to our configuration file--dest-class=GlobalWeather/Container/SoapServerContainer
allows to specify the fully qualified class name of the container class that will hold all the webservice metadata.soap/src/Container
is the path where to save the container class that holds all the webservice metadata (you will have to configure the auto loader to load it)
Using the server
Once all the metadata are generated we can use our SOAP server.
Let's see a minimal example:
// composer auto loader require __DIR__ . '/vendor/autoload.php'; // instantiate the main container class // the name was defined by --dest-class=GlobalWeather/Container/SoapServerContainer // parameter during the generation process $container = new SoapServerContainer(); // create a JMS serializer instance $serializer = SoapContainerBuilder::createSerializerBuilderFromContainer($container)->build(); // get the metadata from the container $metadata = $container->get('goetas_webservices.soap.metadata_reader'); $handler = new class() { function anAction($someParam) { return 'OK 123'; } function someAction($someParam, HeadersIncoming $headersIncoming) { $headers = $headersIncoming->getRawheader(); // perform some checks on $headers here return 'OK 123'; } function anotherAction($someParam, HeadersOutgoing $headersOutgoing) { // reply with custom headers $headersOutgoing->addHeader(new Header(new SomeHeaderData())); // reply with custom headers in pure xml $dom = new DOMDocument(); $dom->appendChild($dom->createElement('foo', 'bar')); $headersOutgoing->addHeader(new Header($dom->documentElement)); return 'OK 456'; } function someErrAction($someParam) { throw new CustomExcpetion(); // converted in a soap fault } }; $router = new DefaultRouter(new ConfiguredRoute($handler)); $factory = new ServerFactory($metadata, $serializer, $router); // get the soap server $server = $factory->getServer('test.wsdl'); // create psr7 request $request = \Laminas\Diactoros\ServerRequestFactory::fromGlobals(); // let the server handle the request $response = $server->handle($request); // send the response to the client (using laminas/laminas-httphandlerrunner) $emitter = new \Laminas\HttpHandlerRunner\Emitter\SapiEmitter(); $emitter->emit($response);
