Functions ¶
func Decorate ¶
Decorate decorates the http.Handler with a list of Decorators and returns the decorated http.Handler. Each of the decorators pasted in is a func that takes an http.Hanlder and returns an http.Handler. The idea is to chain the http.Handler h with the decorators so that the decorator funcion is called before h. The Decorators are left associative. The order of the decorators are called as the following (from right / last to the left / first):
h := Decorate(hdl, d3, d2, d1) //same as // h:= d1(d2(d3(hdl))) before d1 before d2 before d3 HandlerFunc after d3 after d2 after d1
Refer to decorator_test for addtional info.
