Upload File

Upload file di gin dapat menggunakan method FormFile() untuk mendapatkan multipart file dari request dan SaveUploadFile() untuk menyimpan file di direktori yang diinginkan. Contohnya seperti code di bawah ini yang digunakan untuk menyimpan gambar.

package main

import (
	"fmt"
	"net/http"

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

func main() {
	r := gin.Default()
	r.GET("/", Upload)
	r.Run(":5000")
}

func Upload(ctx *gin.Context) {
	file, _ := ctx.FormFile("picture")
	err := ctx.SaveUploadedFile(file, fmt.Sprintf("./files/%s", file.Filename))
	if err != nil {
		ctx.JSON(http.StatusBadRequest, gin.H{
			"status":  http.StatusOK,
			"message": err,
		})
		return
	}

	ctx.JSON(http.StatusOK, gin.H{
		"status":  http.StatusOK,
		"message": fmt.Sprintf("'%s' has been uploaded: ", file.Filename),
	})
}

Upload lebih dari 1 file (.png dan .txt)

package main

import (
	"fmt"
	"net/http"

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

func main() {
	r := gin.Default()
	r.GET("/", Upload)
	r.Run(":5000")
}

func Upload(ctx *gin.Context) {
	file, _ := ctx.FormFile("picture")
	err := ctx.SaveUploadedFile(file, fmt.Sprintf("./files/%s", file.Filename))
	if err != nil {
		ctx.JSON(http.StatusBadRequest, gin.H{
			"status":  http.StatusOK,
			"message": err,
		})
		return
	}

	file2, _ := ctx.FormFile("txt")
	err = ctx.SaveUploadedFile(file2, fmt.Sprintf("./files/%s", file2.Filename))
	if err != nil {
		ctx.JSON(http.StatusBadRequest, gin.H{
			"status":  http.StatusOK,
			"message": err,
		})
		return
	}

	ctx.JSON(http.StatusOK, gin.H{
		"status":  http.StatusOK,
		"message": fmt.Sprintf("'%s' and '%s' has been uploaded: ", file.Filename, file2.Filename),
	})
}
