params#

Create an extended request body kwarg definition.

Parameters:

const – A boolean flag dictating whether this parameter is a constant. If True, the value passed to the parameter must equal its default value. This also causes the OpenAPI const field to be populated with the default value.
content_encoding – The content encoding of the value. Applicable on to string values. See OpenAPI 3.1 for details.
default – A default value. If const is true, this value is required.
description – String value used in the description section of the OpenAPI schema for the given parameter.
examples – A list of Example models.
external_docs – A url pointing at external documentation for the given parameter.
ge – Constrict value to be greater or equal to a given float or int. Equivalent to minimum in the OpenAPI specification.
gt – Constrict value to be greater than a given float or int. Equivalent to exclusiveMinimum in the OpenAPI specification.
le – Constrict value to be less or equal to a given float or int. Equivalent to maximum in the OpenAPI specification.
lt – Constrict value to be less than a given float or int. Equivalent to exclusiveMaximum in the OpenAPI specification.
max_items – Constrict a set or a list to have a maximum number of items. Equivalent to maxItems in the OpenAPI specification.
max_length – Constrict a string or bytes value to have a maximum length. Equivalent to maxLength in the OpenAPI specification.
media_type – Defaults to RequestEncodingType.JSON.
min_items – Constrict a set or a list to have a minimum number of items. Equivalent to minItems in the OpenAPI specification.
min_length – Constrict a string or bytes value to have a minimum length. Equivalent to minLength in the OpenAPI specification.
multipart_form_part_limit – The maximal number of allowed parts in a multipart/formdata request. This limit is intended to protect from DoS attacks.
