后台(MVC控制器)
public JsonResult UploadAppraisal(HttpPostedFileBase fileData, string resultPath)
{
if (fileData != null)
{
try
{
// 文件上传后的保存路径
string filePath = Server.MapPath("../Upload/temp");
string Size = HumanReadableFilesize(fileData.ContentLength);
if (!Directory.Exists(filePath))
{
Directory.CreateDirectory(filePath);
} string fileNames = Path.GetFileName(fileData.FileName);// 原始文件名称
string fileName = Regex.Match(fileNames, @".*?(?=[.])").Value;//去掉后缀名字的文件名字
string fileExtension = Path.GetExtension(fileNames); // 文件扩展名
string saveName = Guid.NewGuid().ToString() + fileExtension; // 保存文件名称
string path = filePath + "\\" + saveName;
string Filesize = HumanReadableFilesize(fileData.ContentLength);//字节大小
string FileDw = HumanReadableFile(fileData.ContentLength);//字节单位
fileData.SaveAs(path); return Json(new
{ Success = true, FileName = 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);
}
}
一个页面有多个上传控件
修改jquery.uploadify.js、jquery.uploadify.min.js
var mydate = new Date();
this.movieName = "SWFUpload_" + mydate.getTime().toString();
上传大文件(Web.config)
Web.config添加一下代码
<system.web>
<compilation debug="true" targetFramework="4.5" />
<!--maxRequestLength就是文件的最大字符数，最大值不能超过2个G左右，executionTimeout是超时时间-->
<httpRuntime targetFramework="4.5" maxRequestLength="" executionTimeout="" />
</system.web>
<system.webServer>
<security>
<requestFiltering>
<!--修改服务器允许最大长度-->
<requestLimits maxAllowedContentLength=""/>
</requestFiltering>
</security>
</system.webServer>
