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 uploadimport ("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.Filenamec.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 uploadimport ("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.Filenamec.SaveUploadedFile(file, dst)file_names = append(file_names, file.Filename)}c.JSON(http.StatusOK, gin.H{"message": "success","file_name": file_names,})
}
