获取Uploadify以使用asp.net-mvc

我试图让Uploadify与我的网站一起工作但是我甚至在将文件发送到服务器之前就得到了一个通用的“HTTP错误”(我说这是因为Fiddler没有向我的控制器显示任何发布请求.

我可以正确浏览要上传的文件.队列正确填充了要上载的文件,但是当我点击提交按钮时,队列中的元素变为红色并说出HTTP错误.

无论如何这是我的部分代码：

<% using ( Html.BeginForm( "Upload","Document",FormMethod.Post,new { enctype = "multipart/form-data" } ) ) { %>
<link type="text/css" rel="Stylesheet" media="screen" href="/_assets/css/uploadify/uploadify.css" />
<script type="text/javascript" src="/_assets/js/uploadify/swfobject.js"></script>
<script type="text/javascript" src="/_assets/js/uploadify/jquery.uploadify.v2.1.0.min.js"></script>
<script type="text/javascript">
    $(document).ready(function() {

        $("[ID$=uploadTabs]").tabs();

        var auth = "<% = Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value %>";
        $('#fileInput').uploadify({
            uploader: '/_assets/swf/uploadify.swf',script: '/Document/Upload',folder: '/_uploads',cancelImg: '/_assets/images/cancel.png',auto: false,multi: false,scriptData: { token: auth },fileDesc: 'Any document type',fileExt: '*.doc;*.docx;*.xls;*.xlsx;*.pdf',sizeLimit: 5000000,scriptAccess: 'always',//testing locally. comment before deploy
            buttonText: 'Browse...'
        });

        $("#btnSave").button().click(function(event) {
            event.preventDefault();
            $('#fileInput').uploadifyUpload();
        });

    });
</script>
    <div id="uploadTabs">
        <ul>
            <li><a href="#u-tabs-1">Upload file</a></li>
        </ul>
        <div id="u-tabs-1">
            <div>
            <input id="fileInput" name="fileInput" type="file" />
            </div>
            <div style="text-align:right;padding:20px 0px 0px 0px;">
                <input type="submit" id="btnSave" value="Upload file" />
            </div>
        </div>
    </div>
<% } %>

非常感谢您的帮助！

更新：

我在uploadify脚本中添加了一个“onError”处理程序,以探索发生了哪个错误,如下例所示

onError: function(event,queueID,fileObj,errorObj) {
    alert("Error!!! Type: [" + errorObj.type + "] Info [" + errorObj.info + "]");
}

并发现info属性包含302.我还为uploadify添加了“method”参数,其值为’post’.

我包含我的控制器操作代码以获取信息.我已阅读很多关于uloadify的帖子,似乎我可以使用具有以下签名的动作……

[HttpPost]
public ActionResult Upload(string token,HttpPostedFileBase fileData) {
    FormsAuthenticationTicket ticket = FormsAuthentication.Decrypt(token);
    if (ticket!=null) {
        var identity = new FormsIdentity(ticket);
        if(identity.IsAuthenticated) {
            try {
                //Save file and other code removed
                return Content( "File uploaded successfully!" );
            }
            catch ( Exception ex ) {
                return Content( "Error uploading file: " + ex.Message );
            }
        }
    }
    throw new InvalidOperationException("The user is not authenticated.");
}

有人可以提供一些帮助吗？
