Functions

func ValidateCookieArray

func ValidateCookieArray(
	sch *base.Schema, param *v3.Parameter, value string) []*errors.ValidationError

ValidateCookieArray will validate a cookie parameter that is an array

func ValidateHeaderArray

func ValidateHeaderArray(
	sch *base.Schema, param *v3.Parameter, value string) []*errors.ValidationError

ValidateHeaderArray will validate a header parameter that is an array

func ValidateParameterSchema

func ValidateParameterSchema(
	schema *base.Schema,
	rawObject any,
	rawBlob,
	entity,
	reasonEntity,
	name,
	validationType,
	subValType string) []*errors.ValidationError

ValidateParameterSchema will validate a parameter against a raw object, or a blob of json/yaml. It will return a list of validation errors, if any.

schema: the schema to validate against
rawObject: the object to validate (leave empty if using a blob)
rawBlob: the blob to validate (leave empty if using an object)
entity: the entity being validated
reasonEntity: the entity that caused the validation to be called
name: the name of the parameter
validationType: the type of validation being performed
subValType: the type of sub-validation being performed

func ValidateQueryArray

func ValidateQueryArray(
	sch *base.Schema, param *v3.Parameter, ef string, contentWrapped bool) []*errors.ValidationError

ValidateQueryArray will validate a query parameter that is an array

func ValidateQueryParamStyle

func ValidateQueryParamStyle(param *v3.Parameter, as []*helpers.QueryParam) []*errors.ValidationError

ValidateQueryParamStyle will validate a query parameter by style

Types

type ParameterValidator

type ParameterValidator interface {

	// SetPathItem will set the pathItem for the ParameterValidator, all validations will be performed against this pathItem
	// otherwise if not set, each validation will perform a lookup for the pathItem based on the *http.Request
	SetPathItem(path *v3.PathItem, pathValue string)

	// ValidateQueryParams accepts an *http.Request and validates the query parameters against the OpenAPI specification.
	// The method will locate the correct path, and operation, based on the verb. The parameters for the operation
	// will be matched and validated against what has been supplied in the http.Request query string.
	ValidateQueryParams(request *http.Request) (bool, []*errors.ValidationError)

	// ValidateHeaderParams validates the header parameters contained within *http.Request. It returns a boolean
	// stating true if validation passed (false for failed), and a slice of errors if validation failed.
	ValidateHeaderParams(request *http.Request) (bool, []*errors.ValidationError)

	// ValidateCookieParams validates the cookie parameters contained within *http.Request.
	// It returns a boolean stating true if validation passed (false for failed), and a slice of errors if validation failed.
	ValidateCookieParams(request *http.Request) (bool, []*errors.ValidationError)

	// ValidatePathParams validates the path parameters contained within *http.Request. It returns a boolean stating true
	// if validation passed (false for failed), and a slice of errors if validation failed.
	ValidatePathParams(request *http.Request) (bool, []*errors.ValidationError)
}

ParameterValidator is an interface that defines the methods for validating parameters There are 4 types of parameters: query, header, cookie and path.

ValidateQueryParams will validate the query parameters for the request
ValidateHeaderParams will validate the header parameters for the request
ValidateCookieParams will validate the cookie parameters for the request
ValidatePathParams will validate the path parameters for the request

Each method accepts an *http.Request and returns true if validation passed, false if validation failed and a slice of ValidationError pointers.

func NewParameterValidator

func NewParameterValidator(document *v3.Document) ParameterValidator

NewParameterValidator will create a new ParameterValidator from an OpenAPI 3+ document
