Gin 框架学习：多文件上传

upload2.go：

package main

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

func main() {
	router := gin.Default()
	// 为 multipart forms 设置较低的内存限制 (默认是 32 MiB)
	// router.MaxMultipartMemory = 8 << 20 // 8 MiB
	router.POST("/upload", func(c *gin.Context) {
		form, _ := c.MultipartForm()
		files := form.File["upload[]"]

		for _, file := range files {
			log.Println(file.Filename)

			dst := "./upload/" + filepath.Base(file.Filename)
			c.SaveUploadedFile(file, dst)
		}

		c.String(http.StatusOK, fmt.Sprintf("%d files uploaded!", len(files)))
	})
	router.Run(":8080")
}

使用 curl 测试上传：

$ curl -X POST http://localhost:8080/upload \
    -F "upload[]=@/Users/appleboy/test1.zip" \
    -F "upload[]=@/Users/appleboy/test2.zip" \
    -H "Content-Type: multipart/form-data"
