最近要做一個文件上傳的東西 經過同事的推薦所以就選擇了plupload，挺強大的 由於項目框架為改動后的MVC 剛一開始破費周折 不過最后總算是完成了 廢話不多說了 粘出來代碼給大家參考吧！文件包大家去官網上面下載吧。下載地址http://www.plupload.com/

前台頁面的代碼JS
$(function () {
// 初始化Flash上傳插件
$("#flash_uploader").pluploadQueue({
runtimes: 'flash', //使用Flash插件
url: '/AJAX/uploadFiles.ashx', //服務器端響應頁面
max_file_size: '10mb', //最大文件限制
chunk_size: '1mb', //一次上傳數據大小
unique_names: true, //是否自動生成唯一名稱
filters: [{ title: "All files", extensions: "doc,docx,ppt,pptx,xls,xlsx,vsd,pot,pps,rtf,wps,et,dps,pdf,txt,epub,rar" }
],
// 縮放圖片
resize: { width: 320, height: 240, quality: 80 },
// SWF文件位置
flash_swf_url: '$webpath/library/js/plupload/plupload.flash.swf',
init: {
FileUploaded: function (up, file, info) {
//一個文件上傳成功
var res = $("#hid_FilePath").val();
var newres = "";
newres = res + info.response;
$("#hid_FilePath").val(newres);
},
Error: function (up, args) {
//發生錯誤
if (args.file) {
alert('[error] File:' + args.file);
} else {
alert('[error]' + args);
}
}
}
});
// 這一塊主要是防止在上傳未結束前表單提交，具體大家可酌情修改編寫
$('form').submit(function (e) {
var uploader = $('#uploader').pluploadQueue(); // 取得上傳隊列
if (uploader.files.length > 0) { // 就是說如果上傳隊列中還有文件
uploader.bind('StateChanged', function () {
if (uploader.files.length === (uploader.total.uploaded + uploader.total.failed)) {
$('form')[0].submit(); //表單提交
}
});
uploader.start();
} else {
alert('隊列中必須至少要有一個文件!');
}
return false;
});
});
</script>
我用的是一般處理程序來處理上傳的核心代碼的uploadFiles.ashx代碼
/// <summary>
/// Json數據序列化
/// </summary>
/// <param name="dic"></param>
/// <returns></returns>
private string toJson(Dictionary<string, string> dic)
{
return EbookServer_Common.Public.toJson(dic);
}
/// <summary>
/// Json數據反序列化
/// </summary>
/// <param name="jsonList"></param>
/// <returns></returns>
private string toJsonArray(List<string> jsonList)
{
return EbookServer_Common.Public.toJsonArray(jsonList);
}
public void UploadFile(HttpContext context)
{
Dictionary<string, string> _dic = new Dictionary<string, string>();
context.Response.CacheControl = "no-cache";
string s_rpath = FileHelper.GetUploadPath();//@"E:\My Documents\Visual Studio 2008\WebSites\SWFUpload\demos\applicationdemo.net";
string Datedir = DateTime.Now.ToString("yy-MM-dd");
string updir = s_rpath + "\\" + Datedir;
string returnstr = "";
int filesize = 0;
List<string> _arr = new List<string>();
if (context.Request.Files.Count > 0)
{
try
{
for (int j = 0; j < context.Request.Files.Count; j++)
{
Dictionary<string, string> _dic_info = new Dictionary<string, string>();
HttpPostedFile uploadFile = context.Request.Files[j];
int offset = Convert.ToInt32(context.Request["chunk"]); //當前分塊
int total = Convert.ToInt32(context.Request["chunks"]);//總的分塊數量
string name = context.Request["name"];
//文件沒有分塊
if (total == 1)
{
if (uploadFile.ContentLength > 0)
{
if (!Directory.Exists(updir))
{
Directory.CreateDirectory(updir);
}
// string fileId = DateTime.Now.ToString("yyyyMMddHHmmssfff") + uploadFile.FileName.Substring(uploadFile.FileName.LastIndexOf("."));
uploadFile.SaveAs(string.Format("{0}\\{1}", updir, name));
filesize = Convert.ToInt32(uploadFile.ContentLength / 1024);
}
}
else
{
//文件 分成多塊上傳
string fullname = WriteTempFile(uploadFile, offset, name);
if (total - offset == 1)
{
//如果是最后一個分塊文件 ，則把文件從臨時文件夾中移到上傳文件 夾中
System.IO.FileInfo fi = new System.IO.FileInfo(fullname);
if (!Directory.Exists(updir))
{
Directory.CreateDirectory(updir);
}
string oldFullName = string.Format(@"{0}\\{1}", updir, name);
FileInfo oldFi = new FileInfo(oldFullName);
if (oldFi.Exists)
{
//文件名存在則刪除舊文件
oldFi.Delete();
}
fi.MoveTo(oldFullName);
filesize = Convert.ToInt32(fi.Length / 1024);
}
}
string filePath = string.Format(@"\\upload\\{0}\\{1}", Datedir, name);
string fileName = name;
string fileSize = filesize.ToString();
returnstr = returnstr + fileName + "||" + filePath + "||" + fileSize + ",";
}
context.Response.ContentEncoding = System.Text.Encoding.GetEncoding("utf-8");
context.Response.Charset = "utf-8";
context.Response.AddHeader("content-type", "application/x-javascript");
context.Response.Write(returnstr.ToString());
}
catch (Exception ex)
{
context.Response.Write("Message" + ex.ToString());
}
}
}
/// <summary>
/// 保存臨時文件
/// </summary>
/// <param name="uploadFile"></param>
/// <param name="chunk"></param>
/// <returns></returns>
private string WriteTempFile(HttpPostedFile uploadFile, int chunk, string name)
{
// string fileId = DateTime.Now.ToString("yyyyMMddHHmmssfff") + uploadFile.FileName.Substring(uploadFile.FileName.LastIndexOf("."));
string tempDir = FileHelper.GetTempPath();
if (!Directory.Exists(tempDir))
{
Directory.CreateDirectory(tempDir);
}
string fullName = string.Format("{0}\\{1}.part", tempDir, name);
if (chunk == 0)
{
//如果是第一個分塊，則直接保存
uploadFile.SaveAs(fullName);
}
else
{
//如果是其他分塊文件 ，則原來的分塊文件，讀取流，然后文件最后寫入相應的字節
FileStream fs = new FileStream(fullName, FileMode.Append);
if (uploadFile.ContentLength > 0)
{
int FileLen = uploadFile.ContentLength;
byte[] input = new byte[FileLen];
// Initialize the stream.
System.IO.Stream MyStream = uploadFile.InputStream;
// Read the file into the byte array.
MyStream.Read(input, 0, FileLen);
fs.Write(input, 0, FileLen);
fs.Close();
}
}
return fullName;
}
還有一個文件處理類 引用來的FileHelper.cs
public FileHelper()
{
//
//TODO: 在此處添加構造函數邏輯
//
}
/// <summary>
/// 獲取上傳目錄
/// </summary>
/// <returns></returns>
public static string GetUploadPath()
{
string path = HttpContext.Current.Server.MapPath("~/");
string dirname = GetDirName();
string uploadDir = path + "\\" + dirname;
CreateDir(uploadDir);
return uploadDir;
}
/// <summary>
/// 獲取臨時目錄
/// </summary>
/// <returns></returns>
public static string GetTempPath()
{
string path = HttpContext.Current.Server.MapPath("~/");
string dirname = GetTempDirName();
string uploadDir = path + "\\" + dirname;
CreateDir(uploadDir);
return uploadDir;
}
private static string GetDirName()
{
return System.Configuration.ConfigurationManager.AppSettings["uploaddir"];
}
private static string GetTempDirName()
{
return System.Configuration.ConfigurationManager.AppSettings["tempdir"];
}
public static void CreateDir(string path)
{
if (!System.IO.Directory.Exists(path))
{
System.IO.Directory.CreateDirectory(path);
}
}
到此就完成了。。。由於時間緊迫 就不廢話了 從中引用了別人的代碼 希望能幫到大家 謝謝！
