使用gin框架上传文件

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

func main(){

	e := gin.Default()
	//set a lower memory limit for multipart forms (default is 32 Mib)
	e.MaxMultipartMemory =  8 << 20 //8Mib

	e.POST("/upload", func(c *gin.Context) {
		file,err := c.FormFile("file")
		if err != nil {
			c.JSON(http.StatusInternalServerError,gin.H{
				"mssage":err.Error(),
			})
		}
		log.Println(file.Filename) //print filename
		dst := fmt.Sprintf("./%s",file.Filename) //构建目标文件的位置
		//save the file to specific dst
		c.SaveUploadedFile(file,dst)
		c.JSON(http.StatusOK,gin.H{
			"message":fmt.Sprintf("%s uploaded!",file.Filename),
		})
	})
	e.Run(":9090")
}
