文件上传前台：前台主要就是用file控件，Form表达Post文件流到后台
<form id="FileUpload" action="/File/Upload/" method="post">
<div class="row cl mt-10 ml-10">
<a>
<input id="FileUp" class="file" runat="server" name="file" type="file" /></a>
<a class="btn btn-success" οnclick="FileUpload()"><i class="Hui-iconfont"></i> 上传</a>
</div>
</form>
function FileUpload() {
var file = $("#FileUp").val();
if (typeof (file) == undefined || file == "") {
layer.msg("请选择文件!", { icon: 2, time: 2000 });
return false;
}
$("#FileUpload").ajaxSubmit(function (json) {
if (json.statusCode == 200) {
layer.msg("上传成功", { icon: 1, time: 2000 });
location.reload();
} else {
layer.msg(json.message, { icon: 2, time: 2000 });
}
});
}
文件上传后台，后台接收文件流
[HttpPost]
public JsonResult Upload(object sender, EventArgs e, int Parentid)
{
JsonResult result = new JsonResult();
string FilePath = "";//ConfigurationManager.AppSettings["FilePath"];
try
{
for (int i = 0; i < Request.Files.Count; i++)
{
if (!string.IsNullOrEmpty(Request.Files[i].FileName))
{
string filename = Path.GetFileName(Request.Files[i].FileName);
FilePath = Path.Combine(Server.MapPath("/") + "\\tempFiles\\Upload", Path.GetFileName(Request.Files[i].FileName));//文件存储路径
Request.Files[i].SaveAs(FilePath);//保存文件
string[] nametype = filename.Split('.');
string msg = "";
FilePath = FilePath.Replace("\\", "\\\\");
nametype[1] = Server.UrlEncode(".") + Server.UrlEncode(nametype[1]);
if (_Bfile.InsertFileUpload(nametype[0], Employee.Id, Parentid, nametype[1], FilePath, out msg) > 0)//存储数据库
result.Data = new { statusCode = 200, message = "上传成功" };
else
result.Data = new { statusCode = 300, message = msg };
}
}
}
catch (Exception ex)
{
result.Data = new { statusCode = 300, message = "上传异常" };
}
return result;
}
文件下载前端：
<a href="/File/Download?FileID=@(dr["Id"])&FileURl=@Html.Raw(dr["FileURl"])&FileName=@(dr["FileName"])&Format=@(dr["FileFormat"])" title="下载"
@Html.Raw(dr["FileFormat"].ToString() == "folder" ? "style=\"display:none\"" : "")>下载 </a>
文件下载后台：
public ActionResult Download(int FileID, string FileURl, string FileName, string Format)
{
FileStream fs = new FileStream(FileURl, FileMode.Open);//打开文件所在路径，获取文件流
byte[] bytes = new byte[(int)fs.Length];
fs.Read(bytes, 0, bytes.Length);
fs.Close();
Response.Charset = "UTF-8";
Response.ContentEncoding = Encoding.GetEncoding("UTF-8");//将文件流按UTF8编码
Response.ContentType = "application/octet-stream";
Response.AddHeader("Content-Disposition", "attachment; filename=" + Server.UrlEncode(FileName) + Server.UrlEncode(Format));
Response.BinaryWrite(bytes);
Response.Flush();//在网页输出文件流
Response.End();
//设置基本信息
_Bfile.InsertFileDownload(FileID, Employee.Id);
return new EmptyResult();
}
