golang gin——文件上传(单文件，多文件)

文件上传

单文件上传

从form-data获取文件

package upload

import (
	"github.com/gin-gonic/gin"
	"net/http"
)
// 单文件上传，多文件上传
func Upload(c *gin.Context) {
	file, _ := c.FormFile("file")  // file为字段名

	dst := "upload_files/" + file.Filename
	c.SaveUploadedFile(file, dst)


	// 都是gin.context作为入参
	c.JSON(http.StatusOK, gin.H{
		"message": "success",
		"file_name": file.Filename,
	})
}

多文件上传

package upload

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

func UploadMulti(c *gin.Context) {
	form, _ := c.MultipartForm()

	files := form.File["files"]
	file_names := make([]string, 0)
	for i := 0; i < len(files); i++ {
		file := files[i]
		dst := "upload_files/" + file.Filename
		c.SaveUploadedFile(file, dst)
		file_names = append(file_names, file.Filename)
	}

	c.JSON(http.StatusOK, gin.H{
		"message": "success",
		"file_name": file_names,
	})
}
