Bases: connexion.operations.abstract.AbstractOperation

Exposes a Swagger 2.0 operation under the AbstractOperation interface. The primary purpose of this class is to provide the function() method to the API. A Swagger2Operation is plugged into the API with the provided (path, method) pair. It resolves the handler function for this operation with the provided resolver, and wraps the handler function with multiple decorators that provide security, validation, serialization, and deserialization.

Parameters:
  • api (apis.AbstractAPI) – api that this operation is attached to

  • method (str) – HTTP method

  • path (str) – relative path to this operation

  • operation (dict) – swagger operation object

  • resolver (resolver.Resolver) – Callable that maps operationID to a function

  • app_produces (list) – list of content types the application can return by default

  • app_consumes (list) – list of content types the application consumes by default

  • path_parameters (list) – Parameters defined in the path level

  • app_security (list) – list of security rules the application uses by default

  • security_schemes (dict) – Security Definitions Object

  • definitions (dict) – Definitions Object

  • validate_responses (bool) – True enables validation. Validation errors generate HTTP 500 responses.

  • strict_validation (bool) – True enables validation on invalid request parameters

  • randomize_endpoint (integer) – number of random characters to append to operation name

  • validator_map (dict) – Custom validators for the types “parameter”, “body” and “response”.

  • pythonic_params (bool) – When True CamelCase parameters are converted to snake_case and an underscore is appended to any shadowed built-ins

  • uri_parser_class (AbstractURIParser) – class to use for uri parsing

  • pass_context_arg_name (str|None) – If not None will try to inject the request context to the function using this name.

classmethod from_spec(cls, spec, api, path, method, resolver, *args, **kwargs)
property parameters(self)

Returns the parameters for this operation

property consumes(self)

Content-Types that the operation consumes

property produces(self)

Content-Types that the operation produces

get_path_parameter_types(self)

Returns the types for parameters in the path

with_definitions(self, schema)

Returns the given schema, but with the definitions from the spec attached. This allows any remaining references to be resolved by a validator (for example).

response_schema(self, status_code=None, content_type=None)

response schema for this endpoint

example_response(self, status_code=None, *args, **kwargs)

Returns example response from spec

property body_schema(self)

The body schema definition for this operation.

property body_definition(self)

The body complete definition for this operation.

There can be one “body” parameter at most.

Return type:

dict

property api(self)
property method(self)

The HTTP method for this operation (ex. GET, POST)

property path(self)

The path of the operation, relative to the API base path

property security(self)
property security_schemes(self)
property responses(self)

Returns the responses for this operation

property validator_map(self)

Validators to use for parameter, body, and response validation

property operation_id(self)

The operation id used to identify the operation internally to the app

property randomize_endpoint(self)

number of random digits to generate and append to the operation_id.

property router_controller(self)

The router controller to use (python module where handler functions live)

property strict_validation(self)

If True, validate all requests against the spec

property pythonic_params(self)

If True, convert CamelCase into pythonic_variable_names

property validate_responses(self)

If True, check the response against the response schema, and return an error if the response does not validate.

get_arguments(self, path_params, query_params, body, files, arguments, has_kwargs, sanitize)

get arguments for handler function

response_definition(self, status_code=None, content_type=None)

response definition for this endpoint

get_mimetype(self)

If the endpoint has no ‘produces’ then the default is ‘application/json’.

:rtype str

property function(self)

Operation function with decorators

Return type:

types.FunctionType

json_loads(self, data)

A wrapper for calling the API specific JSON loader.

Parameters:

data (bytes) – The JSON data in textual form.
