Package validate provides methods to validate a swagger specification,
|
|
as well as tools to validate data against their schema.
|
|
|
|
This package follows Swagger 2.0. specification (aka OpenAPI 2.0). Reference
|
|
can be found here: https://github.com/OAI/OpenAPI-Specification/blob/master/versions/2.0.md.
|
|
|
|
# Validating a specification
|
|
|
|
Validates a spec document (from JSON or YAML) against the JSON schema for swagger,
|
|
then checks a number of extra rules that can't be expressed in JSON schema.
|
|
|
|
Entry points:
|
|
- Spec()
|
|
- NewSpecValidator()
|
|
- SpecValidator.Validate()
|
|
|
|
Reported as errors:
|
|
|
|
[x] definition can't declare a property that's already defined by one of its ancestors
|
|
[x] definition's ancestor can't be a descendant of the same model
|
|
[x] path uniqueness: each api path should be non-verbatim (account for path param names) unique per method. Validation can be laxed by disabling StrictPathParamUniqueness.
|
|
[x] each security reference should contain only unique scopes
|
|
[x] each security scope in a security definition should be unique
|
|
[x] parameters in path must be unique
|
|
[x] each path parameter must correspond to a parameter placeholder and vice versa
|
|
[x] each referenceable definition must have references
|
|
[x] each definition property listed in the required array must be defined in the properties of the model
|
|
[x] each parameter should have a unique `name` and `type` combination
|
|
[x] each operation should have only 1 parameter of type body
|
|
[x] each reference must point to a valid object
|
|
[x] every default value that is specified must validate against the schema for that property
|
|
[x] items property is required for all schemas/definitions of type `array`
|
|
[x] path parameters must be declared a required
|
|
[x] headers must not contain $ref
|
|
[x] schema and property examples provided must validate against their respective object's schema
|
|
[x] examples provided must validate their schema
|
|
|
|
Reported as warnings:
|
|
|
|
[x] path parameters should not contain any of [{,},\w]
|
|
[x] empty path
|
|
[x] unused definitions
|
|
[x] unsupported validation of examples on non-JSON media types
|
|
[x] examples in response without schema
|
|
[x] readOnly properties should not be required
|
|

# Validating a schema
|
|
|
|
The schema validation toolkit validates data against JSON-schema-draft 04 schema.
|
|
|
|
It is tested against the full json-schema-testing-suite (https://github.com/json-schema-org/JSON-Schema-Test-Suite),
|
|
except for the optional part (bignum, ECMA regexp, ...).
|
|
|
|
It supports the complete JSON-schema vocabulary, including keywords not supported by Swagger (e.g. additionalItems, ...)
|
|
|
|
Entry points:
|
|
- AgainstSchema()
|
|
- ...
|
|
|
|
# Known limitations
|
|
|
|
With the current version of this package, the following aspects of swagger are not yet supported:
|
|
|
|
[ ] errors and warnings are not reported with key/line number in spec
|
|
[ ] default values and examples on responses only support application/json producer type
|
|
[ ] invalid numeric constraints (such as Minimum, etc..) are not checked except for default and example values
|
|
[ ] rules for collectionFormat are not implemented
|
|
[ ] no validation rule for polymorphism support (discriminator) [not done here]
|
|
[ ] valid js ECMA regexp not supported by Go regexp engine are considered invalid
|
|
[ ] arbitrary large numbers are not supported: max is math.MaxFloat64
