WSDL (Experimental)

The implementation is experimental and currently only WSDL 1.1 and SOAP 1.1 bindings have been implemented.

The code generator in addition to models derived from xml schemas will also generate dataclasses for messages and simple classes to describe the unique operations.

Make sure you install both cli and soap requirements.

$ pip install xsdata[cli,soap]

$ xsdata --package calculator http://www.dneonline.com/calculator.asmx?WSDL

Message Model

The message models are not any different to xsd derived classes and include the complete structure of the Envelope wrapper.

@dataclass
class CalculatorSoapAddInput:
    class Meta:
        name = "Envelope"
        namespace = "http://schemas.xmlsoap.org/soap/envelope/"

    body: Optional["CalculatorSoapAddInput.Body"] = field(
        default=None,
        metadata={
            "name": "Body",
            "type": "Element",
        }
    )

    @dataclass
    class Body:
        add: Optional[Add] = field(
            default=None,
            metadata={
                "name": "Add",
                "type": "Element",
                "namespace": "http://tempuri.org/",
            }
        )

Operation Class

The DefinitionsMapper will generate simple static classes to describe all the unique operations and the binding procedure.

class CalculatorSoapAdd:
    style = "document"
    location = "http://www.dneonline.com/calculator.asmx"
    transport = "http://schemas.xmlsoap.org/soap/http"
    soap_action = "http://tempuri.org/Add"
    input = CalculatorSoapAddInput
    output = CalculatorSoapAddOutput

Client

The Client is a proxy for consuming web services. The client needs a web service Config with the directives to process requests and responses.

Optionally you can also provide and override

the default transport implementation Transport
the XmlParser with your custom config
the XmlSerializer with your custom config

Creating instances

The client can be initialized from the an operation class directly

client = Client.from_service(CalculatorSoapAdd)
client.config
# Config(style='document', location='http://www.dneonline.com/calculator.asmx', transport='http://schemas.xmlsoap.org/soap/http', soap_action='http://tempuri.org/Add', input=<class 'tests.fixtures.calculator.services.CalculatorSoapAddInput'>, output=<class 'tests.fixtures.calculator.services.CalculatorSoapAddOutput'>)

But you can also override any properties as you see fit

client = Client.from_service(CalculatorSoapAdd, location="http://testurl.com")
client.config
# Config(style='document', location='http://testurl.com', transport='http://schemas.xmlsoap.org/soap/http', soap_action='http://tempuri.org/Add', input=<class 'tests.fixtures.calculator.services.CalculatorSoapAddInput'>, output=<class 'tests.fixtures.calculator.services.CalculatorSoapAddOutput'>)

Or if you know what you are doing

config = Config(
    style="document",
    location="",
    transport=TransportTypes.SOAP,
    soap_action="",
    input=None,
    output=None,
)
client = Client(config=config)

Performing Requests

The send method requires either an object that matches the config input type or a dictionary with raw values that matches the input dataclass field names and structure.

request = CalculatorSoapAddInput(body=CalculatorSoapAddInput.Body(add=Add(10, 2)))
client.send(request)
# CalculatorSoapAddOutput(body=CalculatorSoapAddOutput.Body(add_response=AddResponse(add_result=12)))

client = Client.from_service(CalculatorSoapAdd)
params = {"body": {"add": {"int_a": 3, "int_b": 4}}}
client.send(params)
# CalculatorSoapAddOutput(body=CalculatorSoapAddOutput.Body(add_response=AddResponse(add_result=7)))

You can also provide a dictionary of custom headers as well, although the headers that are needed for the webservice to work can not be overwritten.,

client.send(params, headers={"User-Agent": "xsdata"})
