话不多说，代码如下

package api

import (
   "net/http"
   "github.com/gin-gonic/gin"
   "go-admin/pkg/app"
   "go-admin/pkg/e"
   "go-admin/pkg/logging"
   "go-admin/pkg/upload"
)

// @Summary Import Image
// @Produce  json
// @Param image formData file true "Image File"
// @Success 200 {object} app.Response
// @Failure 500 {object} app.Response
// @Router /api/v1/tags/import [post]
func UploadImage(c *gin.Context) {
   appG := app.Gin{C: c}
   file, image, err := c.Request.FormFile("image")
   if err != nil {
      logging.Warn(err)
      appG.Response(http.StatusInternalServerError, e.ERROR, nil)
      return
   }

   if image == nil {
      appG.Response(http.StatusBadRequest, e.INVALID_PARAMS, nil)
      return
   }

   imageName := upload.GetImageName(image.Filename)
   fullPath := upload.GetImageFullPath()
   savePath := upload.GetImagePath()
   src := fullPath + imageName
   c.JSON(200, gin.H{
      "debug":"错误调试",
      "imageName": imageName,
      "savePath": savePath,
      "src": src,
   })


   if !upload.CheckImageExt(imageName) || !upload.CheckImageSize(file) {
      appG.Response(http.StatusBadRequest, e.ERROR_UPLOAD_CHECK_IMAGE_FORMAT, nil)
      return
   }

   err = upload.CheckImage(fullPath)
   if err != nil {
      logging.Warn(err)
      appG.Response(http.StatusInternalServerError, e.ERROR_UPLOAD_CHECK_IMAGE_FAIL, nil)
      return
   }

   if err := c.SaveUploadedFile(image, src); err != nil {
      logging.Warn(err)
      appG.Response(http.StatusInternalServerError, e.ERROR_UPLOAD_SAVE_IMAGE_FAIL, nil)
      return
   }

   appG.Response(http.StatusOK, e.SUCCESS, map[string]string{
      "image_url":      upload.GetImageFullUrl(imageName),
      "image_save_url": savePath + imageName,
   })
}

注意：需要配置文件上传大小、允许上传类型，否则报错
