如题 ,
直接上单代码 ,
AC代码

然后是.NET后台的代码 ,
后台是MVC写的 , 也可以用其他的方式写 ,
反正逻辑就是这么个情况了 ,
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.Mvc; namespace uploadServer.Controllers
{
[HandleError]
public class HomeController : Controller
{
public JsonResult Index()
{
result<string> ret = new result<string>();
List<string> fileName = new List<string>();
fileName.Add(" Count : " + Request.Files.Count);
ret.code = "404";
if (Request.Files.Count > 0)
{
string path = Server.MapPath("~/files/");
try
{
for (int i = 0; i < Request.Files.Count; i++)
{
string saveName = System.IO.Path.GetRandomFileName() + System.IO.Path.GetExtension(Request.Files[i].FileName);
Request.Files[i].SaveAs(path + saveName);
fileName.Add(path + saveName);
}
ret.code = "200";
}
catch
{
ret.code = "500";
}
}
ret.data = fileName;
return Json(ret, JsonRequestBehavior.AllowGet);
}
} public class result<T>
{
public string code { get; set; }
public string des
{
get
{
return "200 : 上传成功 , 404 : 上传文件未找到 , 500 : 上传文件失败";
}
}
public List<T> data { get; set; }
}
}
