Download the PHP package php-soap/engine without Composer

SOAP Engine

This package contains the contracts and models that allow you to create a customizable SOAP engine. The design looks like this:

• Driver: A driver is a combination of an encoder + decoder + metadata that can work together in order to process SOAP requests.
  • Encoder: Can encode mixed data into a valid SOAP Request.
  • Decoder: Can decode a SOAP Response into a mixed data result.
  • Metadata: Processes the WSDL and returns a collection of available types and methods.
• Transport: Sends the HTTP SOAP Request and receives the HTTP SOAP Response.

Every component above can be used seperately in order to create your own customized SOAP Engine.

Installation

Engines

This package provides engines that can be used in a generic way:

SimpleEngine

The SimpleEngine is a wrapper around a previous defined Driver and a Transport implementation.

LazyEngine

You don't want to be loading WSDL files or SOAP services if you don't need to. By wrapping an engine in a lazy engine, you can prevent any WSDL loading from happening before actually requesting a resource.

Drivers

This package provides drivers that can be used in a generic way:

SimpleDriver

The SimpleEngine is a wrapper around a previous defined Encoder, Decoder and a Metadata implementation.

PartialDriver

The PartialDriver is a wrapper around a previous defined Encoder, Decoder and a Metadata implementation. It is possible to only provide one of the required items. When some of the implementations are missing, it will throw a DriverException when the driver's method is invoked.

List of available components:

• cached-engine: Provides wrappers for storing engines and encoders in a PSR-6 Cache pool.

  • CachedDriver: Decorates a cache around a driver factory.
  • CachedEngine: Decorates a cache around an engine factory.

• ext-soap-engine: An engine based on PHP's ext-soap.

  • ExtSoapEncoder: Uses PHP's SoapClient in order to encode a mixed request body into a SOAP request.
  • ExtSoapDecoder: Uses PHP's SoapClient in order to decode a SOAP Response into mixed data.
  • ExtSoapMetadata: Parses the methods and types from PHP's SoapClient into something more usable.
  • ExtSoapDriver: Combines the ext-soap encoder, decoder and metadata tools into a usable ext-soap preset.
  • ExtSoapClientTransport: Uses PHP's SoapClient to handle SOAP requests.
  • ExtSoapServerTransport: Uses PHP's SoapServer to handle SOAP requests.
  • TraceableTransport: Can be used to decorate another transport and keeps track of the last request and response.

• psr18-transport: Leverages your PSR-18 HTTP client to deal with the HTTP Layer.

  • Psr18Transport: Uses a PSR-18 HTTP client to handle SOAP requests. You can also use fiber-based Async clients!
  • Provides middleware to deal with some common SOAP quirks.
• wsdl-reader: Provides an XML based PHP implementation for collecting WSDL meta-data.
  • Wsdl1MetadataProvider: Provides the methods and types from any WSDL 1 document.

Creating your own engine

Every component of the engine has its own interface. You can choose to build an entire engine or a specific component. The interfaces look like this:

• Decoder
• Driver
• Encoder
• Engine
• Transport

Testing your engine

To make sure that all components have the same end-result, we provide a set of integration tests that can be used to test your custom components.

Usage:

This will make following test cases available:

• AbstractDecoderTest: Can be used to test a custom Decoder.
• AbstractEncoderTest: Can be used to test a custom Encoder.
• AbstractEngineTest: : Can be used to test a custom Engine or Transport.
• AbstractMetadataProviderTest: : Can be used to test a custom Metadata or MetadataProvider.
