• swfupload上传多个大视频


    首先引用文件:

    js:

    <script type="text/javascript">
    var swfu;
    var type = GetQueryString("type");
    var id = GetQueryString("id");
    SWFUpload.onload = function () {
    var settings = {
    flash_url: "swfupload/swfupload.swf",
    upload_url: "Upload.ashx",
    post_params: {
    "ASPSESSID": "<%=Session.SessionID %>",
    "type": type,
    "id": id
    },
    file_size_limit: "0",
    file_types: "*.*",
    file_types_description: "视频文件",
    file_upload_limit: 100,
    file_queue_limit: 50,
    custom_settings: {
    progressTarget: "fsUploadProgress",
    cancelButtonId: "btnCancel"
    },
    debug: false,

    // Button Settings
    button_placeholder_id: "spanButtonPlaceholder",
    button_ 120,
    button_height: 30,
    button_window_mode: SWFUpload.WINDOW_MODE.TRANSPARENT,
    button_cursor: SWFUpload.CURSOR.HAND,

    // The event handler functions are defined in handlers.js

    //swfupload_loaded_handler: swfUploadLoaded,
    file_queued_handler: fileQueued,
    file_queue_error_handler: fileQueueError,
    file_dialog_complete_handler: fileDialogComplete,
    upload_start_handler: uploadStart,
    upload_progress_handler: uploadProgress,
    upload_error_handler: uploadError,
    upload_success_handler: uploadSuccess,
    upload_complete_handler: uploadComplete,
    queue_complete_handler: queueComplete, // Queue plugin event

    // SWFObject settings
    minimum_flash_version: "9.0.28",
    swfupload_pre_load_handler: swfUploadPreLoad,
    // swfupload_load_failed_handler: swfUploadLoadFailed
    };

    swfu = new SWFUpload(settings);
    }
    //获取地址栏参数
    function GetQueryString(name) {

    var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)");

    var r = window.location.search.substr(1).match(reg);

    if (r != null) return unescape(r[2]); return null;

    }
    </script>

    aspx:

    <body>

    <div id="content">

    <form id="form1" action="index.aspx" method="post" enctype="multipart/form-data">
    <div id="divSWFUploadUI">
    <p>
    <span id="spanButtonPlaceholder"></span>
    <input id="btnUpload" type="button" value="选择文件" style=" 120px; height: 30px; font-size: 14pt; font-weight: bold;" />
    <b id="divStatus" style="color: red;">请选择要上传的文件</b>
    <input id="btnCancel" type="button" value="Cancel All Uploads" disabled="disabled" style="display: none; margin-left: 2px; height: 22px; font-size: 8pt;" />
    </p>
    <br style="clear: both;" />

    <div class="fieldset flash" id="fsUploadProgress">
    <span class="legend">上传队例</span>
    </div>

    </div>
    </form>
    </div>
    </body>

    ashx:

    public void ProcessRequest(HttpContext context)
    {
    var Response = context.Response;
    var Request = context.Request;
    var Session = context.Session;

    string type = context.Request["type"];
    string id = context.Request["id"];

    ArtificialDataTitleDomain art = new ArtificialDataTitleDomain();
    ArtificialDataTitleEntity Inspect = new ArtificialDataTitleEntity();

    TestingMachineTitleDomain tmt = new TestingMachineTitleDomain();
    TestingMachineTitleEntity Repair = new TestingMachineTitleEntity();

    string s_rpath = System.Web.HttpContext.Current.Server.MapPath("") + "\" + "doc";
    string Datedir = DateTime.Now.ToString("yy-MM-dd") + " - " + id;
    string updir = s_rpath + "\" + Datedir;
    Response.CacheControl = "no-cache";
    if (Request.Files.Count > 0)
    {
    try
    {
    for (var j = 0; j < Request.Files.Count; j++)
    {
    var uploadFile = Request.Files[j];
    if (uploadFile.ContentLength <= 0) continue;
    if (!Directory.Exists(updir))
    {
    Directory.CreateDirectory(updir);
    }
    var extname = Path.GetExtension(uploadFile.FileName);
    var fullname = DateTime.Now.Year.ToString() + DateTime.Now.Month.ToString() + DateTime.Now.Day.ToString() + DateTime.Now.Hour.ToString() + DateTime.Now.Minute.ToString() + DateTime.Now.Second.ToString();
    var filename = uploadFile.FileName;
    uploadFile.SaveAs(string.Format("{0}\{1}", updir, filename));
    }
    List<string> lst = getFileName(Datedir);
    string allFileName = "";
    if (lst.Count > 0)
    {
    for (int i = 0; i < lst.Count; i++)
    {
    allFileName += lst[i] + ",";
    }
    }
    if (type == "Inspect")
    {
    Inspect = art.FindByID(id);
    Inspect.docUrl = Datedir + "*" + allFileName;
    art.Update(Inspect);
    }
    else if (type == "Repair")
    {
    Repair = tmt.FindByID(id);
    Repair.docUrl = Datedir + "*" + allFileName;
    tmt.Update(Repair);
    }
    }
    catch (Exception ex)
    {
    Response.Write("Message" + ex.ToString());
    }
    }
    }

    //此方法是我自己后期会用到下载

    //而上面的方法获取的FileName只能一个个获取 所以在此循环去取路径下的文件名 比较笨 但实用

    public List<string> getFileName(string url)
    {
    string filePath = string.Format(System.Web.HttpContext.Current.Server.MapPath("doc/{0}"), url);//路径
    DirectoryInfo dir = new DirectoryInfo(filePath);
    FileInfo[] fileInfo = dir.GetFiles();
    List<string> fileNames = new List<string>();
    foreach (FileInfo item in fileInfo)
    {
    fileNames.Add(item.Name);
    }
    return fileNames;

    }

    特别说明:

    此方法适用于单个文件2G以下的多文件上传。下次更新超2G的多文件代码

    关于swfupload里上传后上传列队里的信息会自动消失  可以自己根据需要自己设置如下属性

    fileprogress.js 里的 

    this.setTimer(setTimeout(function () {
     oSelf.disappear();
    }, 10000));

    注释即不消失

    js:

    file_size_limit: "0"    --  不限制上传文件大小

    file_types: "*.*",      ---  不限制文件格式

    post_params: {
    "ASPSESSID": "<%=Session.SessionID %>",
    "type": type,
    "id": id
    },   ---  传值  在ashx中直接   string type = context.Request["type"];  获取
