imageServer.go

package main

import (
    "net/http"
    "fmt"
    "github.com/gin-gonic/gin"
    "github.com/olahol/go-imageupload"
    "time"

func main() {
    r := gin.Default()
    r.StaticFS("/get_image", http.Dir("./image/"))
    r.POST("/upload", func(c *gin.Context) {
      img, err := imageupload.Process(c.Request, "file")

      if err != nil {
        panic(err)
      }

      thumb, err := imageupload.ThumbnailPNG(img, 300, 300)

      if err != nil {
        panic(err)
      }

      thumb.Save(fmt.Sprintf("./image/%d.png", time.Now().Unix()))

      c.Redirect(http.StatusMovedPermanently, "/")
    })

    r.Run(":5000")
}
