实现Sharepoint Request Code 302为301

1、新建项目 》新建类库项目：HttmModules

 

在类文件实现代码：

 

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;
using Microsoft.SharePoint.Publishing;
using Microsoft.SharePoint.WebControls;

using System.Web;
using System.Text.RegularExpressions;


namespace Imtech.SharePoint.Enhancement.HttpModules
{
    public class RedirectModule : IHttpModule
    {

        #region IHttpModule Members
        public void Dispose() { }

        public void Init(HttpApplication context)
        {
            context.BeginRequest += new EventHandler(context_BeginRequest);
        }

        void context_BeginRequest(object sender, EventArgs e)
        {
            HttpApplication app = (HttpApplication)sender;
            string requestUrl = app.Request.Url.ToString();
            Regex regEx = new Regex(@"^https?://.*(?<itemUrl>/[^/]+.[^/.]+)$");
            if (regEx.IsMatch(requestUrl)) return;
            if (!requestUrl.EndsWith("/", StringComparison.CurrentCulture)) requestUrl += "/";
            string destinationUrl = String.Empty;
            SPSecurity.RunWithElevatedPrivileges(delegate()
            {
                try
                {
                    using (SPSite site = new SPSite(requestUrl))
                    {
                        using (SPWeb web = site.OpenWeb())
                        {
                            if (PublishingWeb.IsPublishingWeb(web))
                            {
                                PublishingWeb publishingWeb =
                                    PublishingWeb.GetPublishingWeb(web);
                                if (publishingWeb.DefaultPage.Url.EndsWith("/VariationRoot.aspx", StringComparison.CurrentCultureIgnoreCase))
                                {
                                    string defaultPage = String.Empty;
                                    using (SPWeb nlWeb = site.OpenWeb("nl"))
                                    {
                                        defaultPage = PublishingWeb.GetPublishingWeb(nlWeb).DefaultPage.Url;
                                    }

                                    destinationUrl = String.Concat(requestUrl, "nl/", defaultPage);
                                }
                                else
                                    destinationUrl = String.Concat(requestUrl, publishingWeb.DefaultPage.Url);
                            }
                            else
                                destinationUrl = String.Concat(requestUrl, "default.aspx");
                        }
                    }
                }
                catch { }
            });

            if (!String.IsNullOrEmpty(destinationUrl))
            {
                app.Response.AddHeader("Location", destinationUrl); app.Response.StatusCode = 301;
            }
        }

        #endregion
    }
}

 

2、复制类库HttpModule.dll到网站bin目录下

3、在web.config中配置：

<httpModules>
     <add name="ImtechRedirectModule" type="Imtech.SharePoint.Enhancement.HttpModules.RedirectModule" />
</httpModules>
