A simple rack implementation in Go
Please see http://github.com/ScruffyProdigy/Middleware for some usable premade middleware
run go get github.com/ScruffyProdigy/TheRack/... to install
package main
import (
"github.com/ScruffyProdigy/TheRack/httper"
"github.com/ScruffyProdigy/TheRack/rack"
)
type HelloWare struct{}
func (HelloWare) Run(vars map[string]interface{}, next func()) {
(httper.V)(vars).SetMessageString("Hello " + vars["Object"].(string))
}
type WorldWare struct{}
func (WorldWare) Run(vars map[string]interface{}, next func()) {
vars["Object"] = "World"
next()
}
func main() {
rackup := rack.New()
rackup.Add(WorldWare{})
rackup.Add(HelloWare{})
conn := httper.HttpConnection(":3000")
conn.Go(rackup)
}
Then open up http://localhost:3000 to see "Hello World"
The following code will do the same thing a different way:
package main
import (
"github.com/ScruffyProdigy/TheRack/httper"
"github.com/ScruffyProdigy/TheRack/rack"
"fmt"
"net/http"
)
func HelloWare(vars map[string]interface{}, next func()) {
next()
v := httper.V(vars)
old := v.ResetMessage()
v.SetMessageString("Hello ")
v.AppendMessage(old)
}
func WorldWare(r *http.Request, vars httper.V, next httper.Next) (int, http.Header, []byte) {
w := vars.BlankResponse()
fmt.Fprint(w, "World")
return w.Results()
}
func main() {
rackup := rack.New()
rackup.Add(rack.Func(HelloWare))
rackup.Add(httper.Func(WorldWare))
conn := httper.HttpConnection(":3000")
conn.Go(rackup)
}
and if you just want something short and simple, so will the following code:
package main
import (
"github.com/ScruffyProdigy/TheRack/httper"
"github.com/ScruffyProdigy/TheRack/rack"
)
var HelloWorldWare rack.Func = func(vars map[string]interface{}, next func()) {
httper.V(vars).SetMessageString("Hello World")
}
func main() {
conn := httper.HttpConnection(":3000")
conn.Go(HelloWorldWare)
}
typically these get used together
