Auth-API

Creating an Authentication API with Golang

Installation

You need to install Go on your PC or MacOS and set your Go workspace first

• The first need Go installed (Latest Stable version is awesome)

Getting Started

• To get started, Create a new project then, Create a new file called main.go and enter the following starter code:

package main
import (
  "fmt"
  "net/http"
  "github.com/gin-gonic/gin"
)

POST and GET methods

• To be able to handle GET and POST requests, we create a GetMethod and PostMethod:

func PostMethod(c *gin.Context) {
  fmt.Println("\napi.go 'PostMethod' called")
  message := "PostMethod called"
  c.JSON(http.StatusOK, message)
}
func GetMethod(c *gin.Context) {
  fmt.Println("\napi.go 'GetMethod' called")
  message := "GetMethod called"
  c.JSON(http.StatusOK, message)
}

Main function

• We need to create a Gin router for handling all the requests:

func main() {
  router := gin.Default()
}

• Following this up, we add in the GetMethod and PostMethod:

func main() {
  router := gin.Default()
router.POST("/", PostMethod)
  router.GET("/", GetMethod)
}
