Creating your first HTTP GET method

While writing web applications, we often have to expose our services to the client or to the UI so that they can consume a piece of code running on a different system. Exposing the service can be done with HTTP protocol methods. Out of the many HTTP methods, we will be learning to implement the HTTP GET method in this recipe.

How to do it…

1. Install the github.com/gorilla/mux package using the go get command, as follows:

$ go get github.com/gorilla/mux

2. Create http-rest-get.go where we will define two routes—/employees and /employee/{id} along with their handlers. The former writes the static array of employees and the latter writes employee details for the provided ID to an HTTP response stream, as follows:

package main
import 
(
  "encoding/json"
  "log"
  "net/http"
  "github.com/gorilla/mux"
)
const 
(
  CONN_HOST = "localhost"
  CONN_PORT = "8080"
)
type Route struct 
{
  Name string
  Method string
  Pattern string
  HandlerFunc http.HandlerFunc
}
type Routes...
