定义模板 需要在上传文件的 form 表单上面需要加入 enctype="multipart/form-data"

单文件上传

	r.POST("/admin/user/doUpload",  func(c *gin.Context) {
		username := c.PostForm("username")
		file, err := c.FormFile("face")
		dst := path.Join("./static/upload", file.Filename)
		if err==nil{
			//成功
			//存储文件到本地
			c.SaveUploadedFile(file,dst)
		}
		c.JSON(200,gin.H{
			"msg":"上传成功",
		})
		c.JSON(200,gin.H{
			"success":true,
			"username":username,
			"dst":dst,
		})
		})

不同文件名的多文件上传

	r.POST("/admin/user/doeidt",  func(c *gin.Context) {
		username := c.PostForm("username")
		file1, err1 := c.FormFile("face1")
		dst1 := path.Join("./static/upload", file1.Filename)
		if err1==nil{
			//成功
			//存储文件到本地
			c.SaveUploadedFile(file1,dst1)
		}
		file2, err2 := c.FormFile("face2")
		dst2 := path.Join("./static/upload", file2.Filename)
		if err2==nil{
			//成功
			//存储文件到本地
			c.SaveUploadedFile(file2,dst2)
		}
		c.JSON(200,gin.H{
			"success":true,
			"username":username,
			"dst1":dst1,
			"dst2":dst2,
		})
	})

相同名字的多个文件上传

	r.POST("/admin/user/doeidtnames",  func(c *gin.Context) {
		username := c.PostForm("username")
		form, _ := c.MultipartForm()
		files := form.File["face[]"]
		for _, file := range files {
			// 上传文件至指定目录
			dst := path.Join("./static/upload", file.Filename)
			c.SaveUploadedFile(file, dst)
		}
		c.JSON(200,gin.H{
			"success":true,
			"username":username,
		})
	})
