Controller中
[HttpPost] public JsonResult Upload(HttpPostedFileBase fileData) { if (fileData != null) { try { // 文件上传后的保存路径 string filePath = Server.MapPath("~/Uploads/"); if (!Directory.Exists(filePath)) { Directory.CreateDirectory(filePath); } string fileName = Path.GetFileName(fileData.FileName);// 原始文件名称 string fileExtension = Path.GetExtension(fileName); // 文件扩展名 string saveName = Guid.NewGuid().ToString() + fileExtension; // 保存文件名称 int filesize = fileData.ContentLength / 1024; if (filesize > 1024 || filesize <= 2 || (fileExtension != ".jpg" && fileExtension != ".png" && fileExtension != ".gif")) { return Json(new { Success = false, Message = "上传失败！\r请上传jpg/png格式图片,文件大小不要超过1MB" }, JsonRequestBehavior.AllowGet); } else { fileData.SaveAs(filePath + saveName); return Json(new { Success = true, FilePath = "/Uploads/" + saveName }); } } catch (Exception ex) { return Json(new { Success = false, Message = ex.Message }, JsonRequestBehavior.AllowGet); } } else { return Json(new { Success = false, Message = "请选择要上传的文件！" }, JsonRequestBehavior.AllowGet); } }
在后台应用中会遇到HTTP 302的错误 这是因为应用插件的过程中 没有了session 所以public JsonResult Upload(HttpPostedFileBase fileData) 最好放到一个没有访问权限的Controller中！
