Functions ¶
func CanMakeHandler ¶
CanMakeHandler reports whether a macro template needs a special macro's evaluator handler to be validated before procceed to the next handler(s). If the template does not contain any dynamic attributes and a special handler is NOT required then it returns false.
func MakeFilter ¶
MakeFilter returns a Filter which reports whether a specific macro template and its parameters pass the serve-time validation.
func MakeHandler ¶
MakeHandler creates and returns a handler from a macro template, the handler evaluates each of the parameters if necessary at all. If the template does not contain any dynamic attributes and a special handler is NOT required then it returns a nil handler.
Types ¶
type ParamErrorHandler ¶ added in v12.2.0
ParamErrorHandler is a special type of Iris handler which receives any error produced by a path type parameter evaluator and let developers customize the output instead of the provided error code 404 or anyother status code given on the `else` literal.
Note that the builtin macros return error too, but they're handled by the `else` literal (error code). To change this behavior and send a custom error response you have to register it:
app.Macros().Get("uuid").HandleError(func(ctx iris.Context, paramIndex int, err error)).
You can also set custom macros by `app.Macros().Register`.
See macro.HandleError to set it.
