1 [HttpPost] 2 public ActionResult UploadImage() 3 { 4 //文件保存路径 5 const string savePath = "/Content/Images/"; 6 //上传文件类型 7 const string fileTypes = "gif,jpg,jpeg,png,bmp"; 8 //上传文件大小 9 const int maxSize = 10000000; 10 11 var hash = new Hashtable(); 12 //获取文件信息 13 HttpPostedFileBase file = Request.Files["imgFile"]; 14 if (file == null) 15 { 16 hash = new Hashtable(); 17 hash["error"] = 1; 18 hash["message"] = "请选择文件"; 19 return Json(hash, "text/html;charset=UTF-8"); 20 } 21 22 string dirPath = Server.MapPath(savePath); 23 if (!Directory.Exists(dirPath)) 24 { 25 //不存在该目录则创建一个 26 Directory.CreateDirectory(dirPath); 27 //hash = new Hashtable(); 28 //hash["error"] = 1; 29 //hash["message"] = "上传目录不存在"; 30 //return Json(hash, "text/html;charset=UTF-8"); 31 } 32 33 string fileName = file.FileName; 34 string fileExt = Path.GetExtension(fileName).ToLower(); 35 //文件大小判断 36 if (file.InputStream == null || file.InputStream.Length > maxSize) 37 { 38 hash = new Hashtable(); 39 hash["error"] = 1; 40 hash["message"] = "上传文件大小超过限制"; 41 return Json(hash, "text/html;charset=UTF-8"); 42 } 43 44 if (string.IsNullOrEmpty(fileExt) || Array.IndexOf(fileTypes.Split(','), fileExt.Substring(1).ToLower()) == -1) 45 { 46 hash = new Hashtable(); 47 hash["error"] = 1; 48 hash["message"] = "上传文件扩展名是不允许的扩展名"; 49 return Json(hash, "text/html;charset=UTF-8"); 50 } 51 52 var newFileName = DateTime.Now.ToString("yyyyMMddHHmmss", DateTimeFormatInfo.InvariantInfo) + fileExt; 53 var filePath = dirPath + newFileName; 54 file.SaveAs(filePath); 55 var fileUrl = savePath + newFileName; 56 57 hash = new Hashtable(); 58 hash["error"] = 0; 59 hash["url"] = fileUrl; 60 61 return Json(hash, "text/html;charset=UTF-8"); 62 }
