MVC使用uploadify3.1 IE下正常 firefox、chrome出现HTTPERROR 302错误解决办法

jquery uploadify在ie下可以正常上传，在实现异步上传的时候，每一个文件在上传时都会提交给服务器一个请求。每个请求都需要安全验证，session 和cookie的校验。是的，就是这样。由于jquery uploadify是借助flash来实现上传的，每一次向后台发送数据流请求时，ie会自动把本地cookie存储捆绑在一起发送给服务器。但 firefox、chrome不会这样做，他们会认为这样不安全。

首先需要对global.asxa添加如下内容

    protected void Application_BeginRequest(object sender, EventArgs e)
2         {
3             /* we guess at this point session is not already retrieved by application so we recreate cookie with the session id... */
4             try
5             {
6                 string session_param_name = "ASPSESSID";
7                 string session_cookie_name = "ASP.NET_SessionId";
8
9                 if (HttpContext.Current.Request.Form[session_param_name] != null)
10                 {
11                     UpdateCookie(session_cookie_name, HttpContext.Current.Request.Form[session_param_name]);
12                 }
13                 else if (HttpContext.Current.Request.QueryString[session_param_name] != null)
14                 {
15                     UpdateCookie(session_cookie_name, HttpContext.Current.Request.QueryString[session_param_name]);
16                 }
17             }
18             catch
19             {
20             }
21
22             try
23             {
24                 string auth_param_name = "AUTHID";
25                 string auth_cookie_name = FormsAuthentication.FormsCookieName;
26
27                 if (HttpContext.Current.Request.Form[auth_param_name] != null)
28                 {
29                     UpdateCookie(auth_cookie_name, HttpContext.Current.Request.Form[auth_param_name]);
30                 }
31                 else if (HttpContext.Current.Request.QueryString[auth_param_name] != null)
32                 {
33                     UpdateCookie(auth_cookie_name, HttpContext.Current.Request.QueryString[auth_param_name]);
34                 }
35
36             }
37             catch
38             {
39             }
40         }
41
42         private void UpdateCookie(string cookie_name, string cookie_value)
43         {
44             HttpCookie cookie = HttpContext.Current.Request.Cookies.Get(cookie_name);
45             if (null == cookie)
46             {
47                 cookie = new HttpCookie(cookie_name);
48             }
49             cookie.Value = cookie_value;
50             HttpContext.Current.Request.Cookies.Set(cookie);
51         }

初始化页面上传插件代码如下

 1     <script type="text/javascript">
 2         var auth = "@(Request.Cookies[FormsAuthentication.FormsCookieName]==null ? string.Empty : Request.Cookies[FormsAuthentication.FormsCookieName].Value)";
 3         var ASPSESSID = "@Session.SessionID";
 4 
 5         $(function () {
 6             $('#upload').uploadify({
 7                 'formData': { 'folder': '/Upload', 'ASPSESSID': ASPSESSID, 'AUTHID': auth },
 8                 'buttonText': '浏览',
 9                 'buttonClass': 'browser',
10                 'fileSizeLimit' : '100KB',
11                 'fileTypeExts': '*.xls;*.xlsx',
12                 'removeCompleted': false,
13                 'swf': '@Url.Content("~/Scripts/Uploadify/uploadify.swf")',
14                 'uploader': '/Upload',
15                 'onUploadSuccess': function (file, data, response) {}
16             });
17         });
18     </script>
