MVC使用uploadify3.1 IE下正常 firefox、chrome出現HTTPERROR 302錯誤解決辦法

jquery uploadify在ie下能夠正常上傳，在實現異步上傳的時候，每個文件在上傳時都會提交給服務器一個請求。每一個請求都須要安全驗證，session 和cookie的校驗。是的，就是這樣。因爲jquery uploadify是藉助flash來實現上傳的，每一次向後臺發送數據流請求時，ie會自動把本地cookie存儲捆綁在一塊兒發送給服務器。但 firefox、chrome不會這樣作，他們會認爲這樣不安全。

首先須要對global.asxa添加以下內容

    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         }

 

 

 

初始化頁面上傳插件代碼以下

 

 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': '瀏覽',  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>
