Gin 框架学习：单文件上传

upload1.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) {
		file, err := c.FormFile("file")
		if err != nil {
			c.String(http.StatusBadRequest, fmt.Sprintf("get form err: %s", err.Error()))
		}

		log.Println(file.Filename)

		dst := "./upload/" + filepath.Base(file.Filename)
		if err := c.SaveUploadedFile(file, dst); err != nil {
			c.String(http.StatusBadRequest, fmt.Sprintf("upload file err: %s", err.Error()))
		}

		c.String(http.StatusOK, fmt.Sprintf("'%s' uploaded!", file.Filename))
	})

	router.Run(":8080")
}

使用 curl 测试上传：

$ curl -X POST http://localhost:8080/upload \
    -F "file=@./test.zip" \
    -H "Content-Type: multipart/form-data"
