This does not include the host or base path of the API. For example, in `/items/{itemId}`, +// the path parameter is `itemId`. +// * Query - Parameters that are appended to the URL. For example, in `/items?id=###`, the query parameter is `id`. +// * Header - Custom headers that are expected as part of the request. +// * Body - The payload that's appended to the HTTP request. Since there can only be one payload, there can only be +// _one_ body parameter. The name of the body parameter has no effect on the parameter itself and is used for +// documentation purposes only. Since Form parameters are also in the payload, body and form parameters cannot exist +// together for the same operation. +// * Form - Used to describe the payload of an HTTP request when either `application/x-www-form-urlencoded` or +// `multipart/form-data` are used as the content type of the request (in Swagger's definition, +// the [`consumes`](#operationConsumes) property of an operation). This is the only parameter type that can be used +// to send files, thus supporting the `file` type. Since form parameters are sent in the payload, they cannot be +// declared together with a body parameter for the same operation. Form parameters have a different format based on +// the content-type used (for further details, consult http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4). +// * `application/x-www-form-urlencoded` - Similar to the format of Query parameters but as a payload. +// For example, `foo=1&bar=swagger` - both `foo` and `bar` are form parameters. This is normally used for simple +// parameters that are being transferred. +// * `multipart/form-data` - each parameter takes a section in the payload with an internal header. +// For example, for the header `Content-Disposition: form-data; name="submit-name"` the name of the parameter is +// `submit-name`. This type of form parameters is more commonly used for file transfers. +// +// For more information: http://goo.gl/8us55a#parameterObject +type Parameter struct { + Refable + CommonValidations + SimpleSchema + VendorExtensible + ParamProps +} + +// JSONLookup look up a value by the json property name +func (p Parameter) JSONLookup(token string) (interface{}, error) { + if ex, ok := p.Extensions[token];
