How to use kcd.Handler

The kcd.Handler takes a function (which is your handler) and a default status code.

It returns a normal standard http.HandlerFuncso you can use it with classic routers.

r.Get("/superman", kcd.Handler(YourMagicHandler, http.StatusOK))

YourMagicHandler is a handler of your application, this is where the magic happens!

Construct your handler

Function parameters accepted

• context.Context

• http.ResponseWriter

• *http.Request

• Your custom input struct as a pointer

Function return

• Your custom output (could be either a pointer or non-pointer type)

• error

Additional information

The minimal signature of your function looks like this:

func MagicHandler() error

The maximal signature of your function may look like this:

func MagicHandler(ctx context.Context, res http.ResponseWriter, req *http.Request, in *MyInput) (out MyOutpput, err error)

• All inputs parameters can be omitted

• The order of inputs parameters is not important

• The Input (represented as in *MyInput) must be a pointer

• The order of the return must be preserved with the error as the last parameter

Exception

You can use the standard http handler.
