suds.argparser module

Suds web service operation invocation function argument parser.

See the parse_args() function description for more detailed information.

suds.argparser.parse_args(method_name, param_defs, args, kwargs, external_param_processor, extra_parameter_errors)

Parse arguments for suds web service operation invocation functions.

Suds prepares Python function objects for invoking web service operations. This function implements generic binding agnostic part of processing the arguments passed when calling those function objects.

Argument parsing rules:
  • Each input parameter element should be represented by single regular Python function argument.
  • At most one input parameter belonging to a single choice parameter structure may have its value specified as something other than None.
  • Positional arguments are mapped to choice group input parameters the same as is done for a simple all/sequence group - each in turn.

Expects to be passed the web service operation’s parameter definitions (parameter name, type & optional ancestry information) in order and, based on that, extracts the values for those parameter from the arguments provided in the web service operation invocation call.

Ancestry information describes parameters constructed based on suds library’s automatic input parameter structure unwrapping. It is expected to include the parameter’s XSD schema ‘ancestry’ context, i.e. a list of all the parent XSD schema tags containing the parameter’s <element> tag. Such ancestry context provides detailed information about how the parameter’s value is expected to be used, especially in relation to other input parameters, e.g. at most one parameter value may be specified for parameters directly belonging to the same choice input group.

Rules on acceptable ancestry items:
  • Ancestry item’s choice() method must return whether the item represents a <choice> XSD schema tag.
  • Passed ancestry items are used ‘by address’ internally and the same XSD schema tag is expected to be identified by the exact same ancestry item object during the whole argument processing.

During processing, each parameter’s definition and value, together with any additional pertinent information collected from the encountered parameter definition structure, is passed on to the provided external parameter processor function. There that information is expected to be used to construct the actual binding specific web service operation invocation request.

Raises a TypeError exception in case any argument related errors are detected. The exceptions raised have been constructed to make them as similar as possible to their respective exceptions raised during regular Python function argument checking.

Does not support multiple same-named input parameters.

In cases where multiple services have been defined and no default has been specified, the service is found by name (or index) and a PortSelector for the service is returned. In all cases, attribute access is forwarded to the PortSelector for either the first service or the default service (when specified).
