初始化webuploader

文件上传后台方法
public ActionResult UploadFile() { if (Request.Files.Count <= 0) { return Content(JsonConvert.SerializeObject(new {error = "0", msg = "文件为空。"})); } string addr = Request["Address"]; if (string.IsNullOrEmpty(addr)) { return Content(JsonConvert.SerializeObject(new { error = "0", msg = "地址为空。" })); } string dirPath = Server.MapPath("/UploadFiles/" + addr); if (!Directory.Exists(dirPath)) { Directory.CreateDirectory(dirPath); } var file = Request.Files[0]; string ext = Path.GetExtension(file.FileName); string fileName = Guid.NewGuid().ToString() + ext; string filePath = Path.Combine(dirPath, fileName); // 绝对路径 string returnPath = Path.Combine("/UploadFiles/" + addr, fileName); // 返回的路径 try { file.SaveAs(filePath); return Content(JsonConvert.SerializeObject(new { error = "1", msg = "上传成功", filePath = returnPath })); } catch (Exception e) { return Content(JsonConvert.SerializeObject(new { error = "0", msg = "上传失败" })); } }
请求后台方法
var url = $('#filePath').val(); $.post('/Student/AddImportData', { path: url }, function (msg) { if (msg=="success") { $('#filePath').val(''); $("#thelist").remove(); $.messager.alert("提示", "导入成功",'info'); ReloadClearData(); $("#import").dialog('close'); return; } $.messager.alert("提示", msg, 'error'); })
