In my last post, Installing GoREST on Ubuntu Linux, I mentioned that I should really post a simple example of using GoREST. Here’s some example code for a Get and Post request using GoREST web services in golang.
Note that I’m also using the go-sql-driver/mysql driver for MySQL in golang. To install the driver, simply run:
$ go get github.com/go-sql-driver/mysql
Also, this example isn’t actually using JSON. Check out the link at the end of this post for a JSON example.
package main
import (
"code.google.com/p/gorest"
_ "github.com/go-sql-driver/mysql"
"database/sql"
"net/http"
"log"
"time"
"os"
"strconv"
)
func main() {
// GoREST usage: http://localhost:8181/tutorial/hello
gorest.RegisterService(new(Tutorial)) //Register our service
http.Handle("/",gorest.Handle())
http.ListenAndServe(":8181",nil)
}
//Service Definition
type Tutorial struct {
gorest.RestService `root:"/tutorial/" consumes:"application/json" produces:"application/json"`
hello gorest.EndPoint `method:"GET" path:"/hello/" output:"string"`
insert gorest.EndPoint `method:"POST" path:"/insert/" postdata:"int"`
}
func(serv Tutorial) Hello() string{
return "Hello World"
}
func(serv Tutorial) Insert(number int) {
db, err := sql.Open("mysql", "root:password@/dbname?charset=utf8")
db.Exec("INSERT INTO table (number) VALUES(strconv.Itoa(number) + ");")
db.Close()
serv.ResponseBuilder().SetResponseCode(200)
}
I’m using Postman REST Client for my post tests, you can download Postman for free from the Chrome web store. (Blog post on using Postman with JSON.)
