URL重寫

url重寫，要把代碼寫在global文件中，默認的global文件中沒有給Application_BeginRequest事件，所以手工添加了一個

Application_BeginRequest 在程式被訪問時調用，發生在頁面初始化之前，故才可以使RewritePath生效

運用了該方法之后，訪問網頁時，url會是：

首頁：http://localhost/mypro/memberzone/suyangxian/index.aspx

http://localhost/mypro/memberzone/?uid=suyangxian

共享模塊：http://localhost/mypro/memberzone/suyangxian/share.aspx

http://localhost/mypro/memberzone/share.aspx?uid=suyangxian

[C# code]

void Application_BeginRequest(object sender, EventArgs e)
    {
        /*
         * 老地址，轉化成新地址
         * */

        HttpContext context = ((HttpApplication)sender).Context;
        string path = context.Request.Url.ToString().ToLower();
        if (path.Contains("memberzone/index.aspx?uid="))
        {
            string questUid = Request.QueryString["uid"];
            if (!CoolFuncs.IsNullorEmpty(questUid))
            {
                //實際地址換成重寫之后的地址
                string ss = "index.aspx?uid=" + questUid;
                string rePath = path.Replace(ss, "");
                rePath += questUid + "/index.aspx";
                Response.Redirect(rePath);
            }
        }else

        if (path.Contains("memberzone") && !path.Contains("uid"))
        {
            //分析地址
            string[] ps = path.Split('/');
            try
            {
                //uid所在的index，這里要根據具體的域名作修改，
                //http://localhost/mypro/memberzone/suyangxian/index.aspx
                int k = 5;
                //獲得uid
                string uid = ps[k];
                if (uid != "")
                {
                    string new_path = path.Replace("/" + uid, "");
                    int l2 = new_path.Split('.').Length;

                    int l = new_path.Split('?').Length;
                    string op = (l > 1 ? "&" : "?");
                    string sURL = Pars.SiteUrl;

                    //轉換成實際的地址
                    new_path += op + "uid=" + uid;

//必須要換成虛擬目錄的url
new_path = new_path.Replace(sURL, "~");

//重寫地址
context.RewritePath(new_path);

                }
            }
            catch (Exception Err)
            {
                string tErrors = Err.Message;
            }
        }

    }
