func main() {
    v, err := NewSwaggerValidator("https://raw.githubusercontent.com/OpenBankingUK/read-write-api-specs/v3.1.0/dist/account-info-swagger.json")
    if err != nil {
        panic(err)
    }
    
    failures, err := v.Validate(r)

        panic(err)
    }

    fmt.Printf("Validation failures found:\n%v", failures)    
}

Types

type Failure

type Failure struct {
	Message string
}

Failure represents a validation failure

type Matcher

type Matcher interface {
	Match(pathWithParams, path2 string) bool
}

	Validate(Response) ([]Failure, error)
	IsRequestProperty(method, path, propertpath string) (bool, string, error)
}

Validator validates a HTTP response object against a schema
