Menggunakan metode HTTP

Gin menyediakan metode yang memetakan langsung ke kata kerja HTTP, membuatnya mudah untuk membangun API RESTful. Setiap metode mendaftarkan rute yang hanya merespons tipe permintaan HTTP yang sesuai:

Metode	Penggunaan REST Umum
GET	Mengambil sumber daya
POST	Membuat sumber daya baru
PUT	Mengganti sumber daya yang ada
PATCH	Memperbarui sebagian sumber daya yang ada
DELETE	Menghapus sumber daya
HEAD	Sama seperti GET tetapi tanpa body
OPTIONS	Menjelaskan opsi komunikasi

package main

import (
  "net/http"

  "github.com/gin-gonic/gin"
)

func getting(c *gin.Context) {
  c.JSON(http.StatusOK, gin.H{"method": "GET"})
}

func posting(c *gin.Context) {
  c.JSON(http.StatusOK, gin.H{"method": "POST"})
}

func putting(c *gin.Context) {
  c.JSON(http.StatusOK, gin.H{"method": "PUT"})
}

func deleting(c *gin.Context) {
  c.JSON(http.StatusOK, gin.H{"method": "DELETE"})
}

func patching(c *gin.Context) {
  c.JSON(http.StatusOK, gin.H{"method": "PATCH"})
}

func head(c *gin.Context) {
  c.Status(http.StatusOK)
}

func options(c *gin.Context) {
  c.Status(http.StatusOK)
}

func main() {
  // Creates a gin router with default middleware:
  // logger and recovery (crash-free) middleware
  router := gin.Default()

  router.GET("/someGet", getting)
  router.POST("/somePost", posting)
  router.PUT("/somePut", putting)
  router.DELETE("/someDelete", deleting)
  router.PATCH("/somePatch", patching)
  router.HEAD("/someHead", head)
  router.OPTIONS("/someOptions", options)

  // By default it serves on :8080 unless a
  // PORT environment variable was defined.
  router.Run()
  // router.Run(":3000") for a hard coded port
}

Pengujian dengan curl

Setelah server berjalan, Anda dapat menguji setiap endpoint:

# GET request
curl -X GET http://localhost:8080/someGet

# POST request
curl -X POST http://localhost:8080/somePost

# PUT request
curl -X PUT http://localhost:8080/somePut

# DELETE request
curl -X DELETE http://localhost:8080/someDelete

# PATCH request
curl -X PATCH http://localhost:8080/somePatch

# HEAD request (returns headers only, no body)
curl -I http://localhost:8080/someHead

# OPTIONS request
curl -X OPTIONS http://localhost:8080/someOptions
