后台
string fileName = string.Empty;
string serverPath = string.Empty;
string serverPath = string.Empty;
HttpFileCollection httpFileCollection = Request.Files;
HttpPostedFile file = httpFileCollection[0];
fileName = Path.GetFileName(file.FileName);
serverPath = context.Server.MapPath("/");//设置上传路径
file.SaveAs(serverPath);
----------------------------------------
遇到一个小问题，后台正常走完返回不进success，该问题解决办法：dataType设置了json，返回的格式不匹配，修改为json格式就可以，或者取消dataType设置。
