package main
import (
"fmt"
"io"
"log"
"net/http"
"os"
"github.com/gin-gonic/gin"
)
func upload(c *gin.Context) {
file, header, err := c.Request.FormFile( "file" )
if err != nil {
c.String(http.StatusBadRequest, fmt.Sprintf( "file err : %s" , err.Error()))
return
}
filename := header.Filename
out, err := os.Create( "public/" + filename)
if err != nil {
log .Fatal(err)
}
defer out.Close()
_, err = io.Copy(out, file)
if err != nil {
log .Fatal(err)
}
filepath := "http://localhost:8080/file/" + filename
c.JSON(http.StatusOK, gin.H{ "filepath" : filepath})
}
func main() {
router := gin.Default()
router.LoadHTMLGlob( "template/*" )
router.GET( "/" , func(c *gin.Context) {
c.HTML(http.StatusOK, "select_file.html" , gin.H{})
})
router.POST( "/upload" , upload)
router.StaticFS( "/file" , http.Dir( "public" ))
router.Run( ":8080" )
}

select_file.html的内容为:

< html >
< body >
< form action = "http://localhost:8080/upload/" enctype = "multipart/form-data" method = "POST" >
< input type = "file" name = "file" id = "pic" accept = "*" />
< button type = "submit" >提交</ button >
</ form >
</ body >
</ html >

go run test_gin_server.go
跑起来, 在浏览器上执行:http://localhost:8080/ ,然后就出现了图片上传的页面,于是就可以上传图片了, 玩了一下, OK,服务端对应的public目录中有对应的图片。
不多说。
