How to get json data with golang | gin gonic

 

Welcome today im gonna show you how to get data with golang

   

first we need to go.mod file and install gin framework

$ go mod init "YourProjectFolder" 
$ go get github.com/gin-gonic/gin   

then create main.go and create main function

package main

func main() {

}

so right now we have to crate struct and array 

type words struct {
   ID  string `json:"id"`
   ENG string `json:"eng"`
    TR  string `json:"tr"`
}

 

var dictionary = []words{
    {ID: "1", ENG: "hello",   TR: "merhaba"},
    {ID: "2", ENG: "cat",     TR: "kedi"},
    {ID: "3", ENG: "car",     TR: "araba"},
    {ID: "4", ENG: "door",    TR: "kapı"},
}

we have array and we need to convert this array to json

func fakeData(c *gin.Context) {
    c.JSON(http.StatusOK, dictionary)
}

Okay now we have json data so lets get this data

package main
import (
    "net/http"
    "github.com/gin-gonic/gin"
)
func main() {
    router := gin.Default()
    router.GET("/fakeData", fakeData) // http://localhost:9090/fakeData
    router.Run(":9090") // localhost:9090
}

and run in terminal 

$ go run "YourProjectFile"
