2.上传页面UpFilePage.aspx

关键代码：

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
<title>上传文件</title>
<link href="/jquery.uploadify/uploadify.css" rel="stylesheet" />

<script type="text/javascript" src="/UploadFiles/2021-04-02/jquery-1.8.3.min.js">


后台的GetFile()方法：





/// <summary>
/// 获取cookie附件信息
/// </summary>
/// <returns></returns>
protected string GetFile()
{
#region 获取cookie附件信息

StringBuilder strHtml = new StringBuilder();
HttpCookie fileCookie = Request.Cookies["FileCookie"];
if (fileCookie != null)
{
string[] fileArray = new string[1];
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
foreach (string objFile in fileArray)
{
if (!string.IsNullOrEmpty(objFile) && objFile.Contains(","))
{
string[] file = objFile.Split(',');
strHtml.Append(@"<div class='uploadifyQueueItem'>");
strHtml.Append(@"<div class='cancel'>");
strHtml.Append("<a href='javascript:deleteFile(\"" + file[1] + "\")'></a>");
//strHtml.Append(@"<img src='/Scripts/jquery.uploadify/cancel.png' border='0'>");
strHtml.Append(@"</div>");
strHtml.Append(@"<span class='fileName'>" + HttpUtility.UrlDecode(file[0]) + "</span><span class='percentage'> - 100%</span><div class='uploadifyProgress'>");
strHtml.Append(@"<div class='uploadifyProgressBar' style='width: 100%;'>");
strHtml.Append(@"</div>");
strHtml.Append(@"</div>");
strHtml.Append(@"</div>");
}
}
}
return strHtml.ToString();
#endregion
}







3.UploadAction文件夹下的一般处理程序：





public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";
string operate = context.Request["operate"];
if (operate == "deleteFile")
{
#region 删除文件附件信息
//获取文件路径
string filePath = context.Server.MapPath(context.Request["file"]);
//判断文件是否存在
if (File.Exists(filePath))
File.Delete(filePath);//删除文件
//获取附件cookie信息
HttpCookie fileCookie = context.Request.Cookies["FileCookie"];
string[] fileArray = new string[1];
if (fileCookie != null)
{
filePath = filePath.Remove(0, filePath.IndexOf("upfiles")).Replace("\\", "/");
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
string strFile = "";
for (int i = 0; i < fileArray.Length; i++)
{
if (!fileArray[i].Contains(filePath))
strFile += fileArray[i] + "|";
}
if (strFile.Contains("|"))
strFile = strFile.Remove(strFile.Length - 1);
fileCookie.Value = strFile;
fileCookie.Expires = DateTime.Now.AddDays(1);
fileCookie.HttpOnly = true;
context.Response.AppendCookie(fileCookie);


StringBuilder strHtml = new StringBuilder();
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
foreach (string objFile in fileArray)
{
if (!string.IsNullOrEmpty(objFile) && objFile.Contains(","))
{
string[] file = objFile.Split(',');
strHtml.Append(@"<div class='uploadifyQueueItem'>");
strHtml.Append(@"<div class='cancel'>");
strHtml.Append("<a href='javascript:deleteFile(\"" + file[1] + "\")'></a>");
//strHtml.Append(@"<img src='/Scripts/jquery.uploadify-v2.1.0/cancel.png' border='0'>");
strHtml.Append(@"</div>");
strHtml.Append(@"<span class='fileName'>" + HttpUtility.UrlDecode(file[0]) + "</span><span class='percentage'> - 100%</span><div class='uploadifyProgress'>");
strHtml.Append(@"<div class='uploadifyProgressBar' style='width: 100%;'>");
strHtml.Append(@"</div>");
strHtml.Append(@"</div>");
strHtml.Append(@"</div>");
}
}
context.Response.Write(strHtml.ToString());
}
#endregion
}
else if (operate == "GetFile")
{
#region 获取上传的附件并展示
StringBuilder strHtml = new StringBuilder();
HttpCookie fileCookie = context.Request.Cookies["FileCookie"];
if (fileCookie != null)
{
string[] fileArray = new string[1];
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
else
fileArray[0] = fileCookie.Value;
foreach (string objFile in fileArray)
{
if (!string.IsNullOrEmpty(objFile) && objFile.Contains(","))
{
string[] file = objFile.Split(',');
strHtml.Append(@"<div class='uploadifyQueueItem'>");
strHtml.Append(@"<div class='cancel'>");
strHtml.Append("<a href='javascript:deleteFile(\"" + file[1] + "\")'>");
//strHtml.Append(@"<img src='/Scripts/jquery.uploadify-v2.1.0/cancel.png' border='0'></a>");
strHtml.Append(@"</div>");
strHtml.Append(@"<span class='fileName'>" + HttpUtility.UrlDecode(file[0]) + "</span><span class='percentage'> - 100%</span><div class='uploadifyProgress'>");
strHtml.Append(@"<div class='uploadifyProgressBar' style='width: 100%;'>");
strHtml.Append(@"</div>");
strHtml.Append(@"</div>");
strHtml.Append(@"</div>");
}
}
}
context.Response.Write(strHtml.ToString());
#endregion
}
}







4.上传文件uploadHandler.ashx一般处理程序代码，文件上传路径可以根据剧情需要自由设定：





public void ProcessRequest(HttpContext context)
{
context.Response.ContentType = "text/plain";

HttpCookie fileCookie = context.Request.Cookies["FileCookie"];
if (fileCookie != null)
{
string[] fileArray = new string[1];
if (fileCookie.Value.Contains("|"))
fileArray = fileCookie.Value.Split('|');
if (fileArray.Length >= 5)
return;
}
else
{
fileCookie = new HttpCookie("FileCookie");
fileCookie.Value = "";
context.Response.Cookies.Add(fileCookie);
}

String aspxUrl = context.Request.Path.Substring(0, context.Request.Path.LastIndexOf("/") + 1);

//文件保存目录路径
String savePath = "/upfiles/";

//文件保存目录URL
String saveUrl = "/upfiles/";

//if (context.Request.Cookies["Member"] != null)
//{
// savePath += context.Request.Cookies["Member"]["MemberId"] + "/";
// saveUrl += context.Request.Cookies["Member"]["MemberId"] + "/";
//}
string Member = Guid.NewGuid().ToString().Trim().Replace("-", "");
savePath += Member + "/";
saveUrl += Member + "/";

//定义允许上传的文件扩展名
/*Hashtable extTable = new Hashtable();
extTable.Add("image", "gif,jpg,jpeg,png,bmp");
extTable.Add("flash", "swf,flv");
extTable.Add("media", "swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb,mp4");
extTable.Add("file", "doc,docx,xls,xlsx,ppt,htm,html,txt,zip,rar,gz,bz2,swf,flv,mp3,wav,wma,wmv,mid,avi,mpg,asf,rm,rmvb,mp4,wps");*/

//最大文件大小
int maxSize = 5242880;

HttpPostedFile imgFile = context.Request.Files["imgFile"];
/*if (imgFile == null)
{
showError("请选择文件。");
}*/

String dirPath = context.Server.MapPath(savePath);
if (!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
//showError("上传目录不存在。");
}

String dirName = context.Request.QueryString["dir"];
if (String.IsNullOrEmpty(dirName))
{
dirName = "file";
}
/*if (!extTable.ContainsKey(dirName))
{
showError("目录名不正确。");
}*/

String fileName = imgFile.FileName;
String fileExt = Path.GetExtension(fileName).ToLower();


/*if (String.IsNullOrEmpty(fileExt) || Array.IndexOf(((String)extTable[dirName]).Split(','), fileExt.Substring(1).ToLower()) == -1)
{
showError("上传文件扩展名是不允许的扩展名。\n只允许" + ((String)extTable[dirName]) + "格式。");
}
if (dirName.Contains("image"))
{
if (imgFile.InputStream == null || imgFile.InputStream.Length > maxSize)
{
showError("上传文件超过5M大小限制。");
}
}*/

//创建文件夹
dirPath += dirName + "/";
saveUrl += dirName + "/";
if (!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
}
String ymd = DateTime.Now.ToString("yyyyMMdd", DateTimeFormatInfo.InvariantInfo);
dirPath += ymd + "/";
saveUrl += ymd + "/";
if (!Directory.Exists(dirPath))
{
Directory.CreateDirectory(dirPath);
}

String newFileName = DateTime.Now.ToString("yyyyMMddHHmmss_ffff", DateTimeFormatInfo.InvariantInfo) + fileExt;
String filePath = dirPath + newFileName;

imgFile.SaveAs(filePath);

String fileUrl = saveUrl + newFileName;

/*Hashtable hash = new Hashtable();
hash["error"] = 0;
hash["url"] = fileUrl;
context.Response.AddHeader("Content-Type", "text/html; charset=UTF-8");
context.Response.Write(JsonMapper.ToJson(hash));
context.Response.End();*/

if (fileCookie != null)
{
string strFile = fileCookie.Value;
if (!string.IsNullOrEmpty(strFile))
strFile = strFile + "|" + HttpUtility.UrlEncode(fileName) + "," + fileUrl;
else
strFile = HttpUtility.UrlEncode(fileName) + "," + fileUrl;
fileCookie.Value = strFile;
fileCookie.Expires = DateTime.Now.AddDays(1);
fileCookie.HttpOnly = true;
context.Response.AppendCookie(fileCookie);
}
context.Response.Write("1");
context.Response.End();
}
