How to display HTML / JSON / XML dynamically in golang with martini?
I am trying to create a simple REST API server on golang site that serves HTML, JSON, or XML format of the same date as requested by the client. I can not understand. Hope I'm not doing anything stupid.
code:
package main
import (
"github.com/go-martini/martini"
"github.com/martini-contrib/render"
)
type Ticket struct {
Number int `json:"number"`
Description string `json:"description"`
State string `json:"state"`
}
func dummyStatus() Ticket {
ticket := Ticket{
Number: 2345,
Description: "A dummy customer ticket",
State: "resolved",
}
return ticket
}
// http://localhost:3000/status/id:1
func ReadStatus(r render.Render, params martini.Params) Ticket {
// read from DB
return dummyStatus()
}
func WriteStatus(params martini.Params) Ticket {
// write to DB
return dummyStatus()
}
func main() {
m := martini.Classic()
m.Use(render.Renderer())
m.Group("/status", func(r martini.Router) {
r.Get("/:id", ReadStatus)
r.Post("/:id", WriteStatus)
})
m.Run()
}
Result: I am requesting JSON and I just get the string
$ curl -i -H "Accept: application/json" -H "Content-Type:application/json" -X GET http://localhost:3000/status/id:12345
HTTP/1.1 200 OK

With some trial and error, I figured it out, however, I am still struggling to get it to work with the routing group. If I ever figure this out, I'll update this answer. Hope this helps.
package main
import (
"github.com/go-martini/martini"
"github.com/martini-contrib/render"
)
type Ticket struct {
Number int `json:"number"`
Description string `json:"description"`
State string `json:"state"`
}
func ReadStatus(p martini.Params) Ticket {
ticket := Ticket{
Number: 645,
Description: "A dummy customer ticket " + p["id"],
State: "resolved",
}
return ticket
}
func main() {
m := martini.Classic()
m.Use(render.Renderer())
m.Get("/status/:id", func(r render.Render, params martini.Params) { r.JSON(200, ReadStatus(params)) })
m.Run()
}
