gin上传文件服务器,使用 golang的gin框架实现，文件上传

一、引入 gin 框架import "ginhub.com/gin-gonic/gin

二、渲染页面router := gin.Default()

router.LoadHTMLGlob("view/*")

router.GET("/upload",func(c *gin.Context) {

c.HTML(http.StatusOK,"upload.tmpl",gin.H{})

})

三、处理上传文件router.POST("/upload", func(c *gin.Context) {

// Source

file, err := c.FormFile("file")

if err != nil {

c.String(http.StatusBadRequest, fmt.Sprintf("get form err: %s", err.Error()))

return

}

basePath := "./upload/"

filename := basePath + filepath.Base(file.Filename)

if err := c.SaveUploadedFile(file, filename); err != nil {

c.String(http.StatusBadRequest, fmt.Sprintf("upload file err: %s", err.Error()))

return

}

c.String(http.StatusOK,fmt.Sprintf("文件 %s 上传成功 ", file.Filename))

})

全部代码：package main

import (

"github.com/gin-gonic/gin"

"net/http"

"fmt"

"path/filepath"

)

func main() {

router := gin.Default()

router.LoadHTMLGlob("view/*")

router.GET("/upload",func(c *gin.Context) {

c.HTML(http.StatusOK,"upload.tmpl",gin.H{})

})

router.MaxMultipartMemory = 8 << 20 // 8 MiB

router.POST("/upload", func(c *gin.Context) {

file, err := c.FormFile("file")

if err != nil {

c.String(http.StatusBadRequest, fmt.Sprintf("get form err: %s", err.Error()))

return

}

basePath := "./upload/"

filename := basePath + filepath.Base(file.Filename)

if err := c.SaveUploadedFile(file, filename); err != nil {

c.String(http.StatusBadRequest, fmt.Sprintf("upload file err: %s", err.Error()))

return

}

c.String(http.StatusOK,fmt.Sprintf("文件 %s 上传成功 ", file.Filename))

})

router.Run(":8080")

}
