PHP implementation of SOAP 1.1 and 1.2 client specifications

PHP implementation of SOAP 1.1 and 1.2 client specifications.
Strengths:
ext-soap
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.
goetas-webservices/soap-client-demo is a demo project that shows how to consume a SOAP api in a generic PHP web application.
The recommended way to install goetas-webservices / soap-client is using Composer:
Add this packages to your composer.json
file.
{
"require": {
"goetas-webservices/soap-client": "^0.3",
},
"require-dev": {
"goetas-webservices/wsdl2php": "^0.5.1",
},
}
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_client:
alternative_endpoints:
MyServiceName:
MySoapPortName: http://localhost:8080/service
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': ~
'http://www.webservicex.net/weather.asmx?WSDL': ~
This file has some important sections:
alternative_endpoints
(optional) allows you to specify alternative URLs that can be used
when developing your integration.
If this parameter is not present, will be used the URL defined by the WSDL file,
but if is set, will be used the specified URL for the service called
MyServiceName and on MySoapPortName port.
unwrap_returns
(optional, default: false) allows to define the "wrapped" SOAP services mode.
Instructs the client to "unwrap" all the returns.
metadata
specifies where are placed WSDL files that will be used to generate al the required PHP metadata.namespaces
(required) defines the mapping between XML namespaces and PHP namespaces.
(in the example we have the http://www.example.org/test/
XML namespace mapped to TestNs\MyApp
)
destinations_php
(required) specifies the directory where to save the PHP classes that belongs to
TestNs\MyApp
PHP namespace. (in this example TestNs\MyApp
classes will ne saved into soap/src
directory.
destinations_jms
(required) specifies the directory where to save JMS Serializer metadata files
that belongs to TestNs\MyApp
PHP namespace.
(in this example TestNs\MyApp
metadata will ne saved into soap/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.
In order to be able to use the SOAP client we have to generate some metadata and PHP classes.
To do it we can run:
bin/soap-client generate \
tests/config.yml \
--dest-class=GlobalWeather/Container/SoapClientContainer \
soap/src-gw/Container
bin/soap-client generate
is the command we are runningtests/config.yml
is a path to our configuration file--dest-class=GlobalWeather/Container/SoapClientContainer
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)Once all the metadata are generated we can use our SOAP client.
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/SoapClientContainer
// parameter during the generation process
$container = new SoapClientContainer();
// create a JMS serializer instance
$serializer = SoapContainerBuilder::createSerializerBuilderFromContainer($container)->build();
// get the metadata from the container
$metadata = $container->get('goetas_webservices.soap.metadata_reader');
$factory = new ClientFactory($metadata, $serializer);
/**
* @var $client \GlobalWeather\SoapStubs\WeatherSoap
*/
// get the soap client
$client = $factory->getClient('http://www.webservicex.net/weather.asmx?WSDL');
// call the webservice
$result = $client->getWeather(2010, "May", "USA");
// call the webservice with custom headers
$result = $client->getWeather(2010, "May", "USA", Header::asMustUnderstand(new SomeAuth('me', 'pwd')));
Please note the @var $client \GlobalWeather\SoapStubs\WeatherSoap
. The generated metadata have also a "stub" class
that allows modern IDE to give you type hinting for parameters and return data.
This allows you to develop faster your client.
Suppose that you have same Webservice with different endpoints (ex. for each customer), so you want to change endpoints dynamically and you don't want to write each new endpoint in your config and run the generator for each customer.
With the help of Symfony's EnvVarProcessorInterface
,
you can use alternative_endpoints
to set dynamically the webservice endpoints.
Here is an example:
# config.yml
soap_client:
alternative_endpoints:
MyServiceName:
MySoapPortName: 'env(custom_vars:ENDPOINT_SERVICE1_PORT1)'
So, SoapClientContainer
will resolve at runtime the endpoint for the specific service and port and the value will be
taken from the ENDPOINT_SERVICE1_PORT1
variable.
Example of simple class that implements EnvVarProcessorInterface
, responsible for providing a values for
our custom endpoint locations (as custom_vars:ENDPOINT_SERVICE1_PORT1
).
// SimpleEnvVarProcessor.php used for the `env(custom_vars:*)` variables resolution
use Symfony\Component\DependencyInjection\EnvVarProcessorInterface;
class SimpleEnvVarProcessor implements EnvVarProcessorInterface
{
private $map = [];
public function __construct(array $map)
{
$this->map = $map;
}
public function getEnv($prefix, $name, \Closure $getEnv)
{
return $this->map[$name];
}
public static function getProvidedTypes()
{
return [];
}
}
At the end, to use the SoapClientContainer
:
// instantiate our variable processor and set the values for our custom variables
$varProcessor = new SimpleEnvVarProcessor([
'ENDPOINT_SERVICE1_PORT1' => 'http://localhost:8080/service'
]);
// create an empty symfony container and set into it the $varProcessor namined as 'custom_vars'
$varContainer = new \Symfony\Component\DependencyInjection\Container();
$varContainer->set('custom_vars', $varProcessor);
// create the soap container and use $varContainer "env()" style variables resolution
$container = new SoapClientContainer();
$container->set('container.env_var_processors_locator', $varContainer);
// now $container can be used as explained in the section "Using the client"
In this way the endpoint for the MyServiceName
.MySoapPortName
will be dynamically resolved to http://localhost:8080/service
even if the WSDL stats something else.
