pkg rewrite provides the http.ResponseWriter implementation and Replacer of the response.
go get -u github.com/Qs-F/rewrite
func main() {
rw := &Rule{
{
Old: "world",
New: "gopher",
},
}
http.Handle("/", rw.MapFunc(func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "hello world")
}))
http.ListenAndServe(":8080", nil)
}
// Open localhost:8080, then you will get "hello gopher"MIT
