動態請求頁面生成靜態頁

話說百度也是這樣提高瀏覽速度的；此案例是控件開發的，MVC或一般處理程序開發的小伙伴們，修修改改一樣可以用的；

后台：

  protected void btnHtml_Click(object sender, EventArgs e)
        {
            if (Request.QueryString["id"] != null)
            {
                string NewId = Request.QueryString["id"];
                CJRZ.Model.Admin.LoanStrategy modeStrategy = bllNews.GetModel(int.Parse(NewId));
                if (modeStrategy != null)
                {
                    CreatHtml cHtml = new CreatHtml();
                    string url = "http://" + HttpContext.Current.Request.Url.Host.ToString() + ":" + HttpContext.Current.Request.Url.Port;
                    string AUrl = url + "/raiders/raiders_article.aspx?id=" + modeStrategy.NewID;
                    //html頁面文件名
                    string fna = Server.MapPath("\\") + "raiders\\" + modeStrategy.NewTypeID + "\\";
                    string FileName = modeStrategy.NewID + ".html";
                    if (cHtml.CreateList(AUrl, fna, FileName))
                    {
                        modeStrategy.HtmlUrl = url + "/raiders/" + modeStrategy.NewTypeID + "/" + FileName;
                        hlkLook.NavigateUrl = modeStrategy.HtmlUrl;
                        if (bllNews.Update(modeStrategy))
                        {
                            MessageBox.Show(this, "生成文件成功");
                        }
                        else
                        {
                            MessageBox.Show(this, "更新數據路徑失敗！");
                        }
                    }
                    else
                    {
                        MessageBox.Show(this, "生成文件失敗！");
                    }
                }
                else
                {
                    MessageBox.Show(this, "獲取新聞對象失敗！");
                }

            }
            else
            {
                MessageBox.Show(this, "獲取ID號失敗！");
            }
        }

前台：

  <asp:Button ID="btnHtml" runat="server" Text="生成靜態頁" onclick="btnHtml_Click" Visible="false" />
                        &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
                           <asp:HyperLink ID="hlkLook" runat="server" style=" color:Blue; font-size:14px;" Target="_blank" >查看頁面</asp:HyperLink>

調用的類：

  public class CreatHtml
    {
        public bool CreateList(string url, string fna,string fileName)
        {
            bool ok;
            //准備生成
            string strHtml;
            StreamReader sr = null; //用來讀取流
            StreamWriter sw = null; //用來寫文件
            Encoding code = Encoding.GetEncoding("utf-8"); //定義編碼

            //構造web請求，發送請求，獲取響應
            WebRequest HttpWebRequest = null;
            WebResponse HttpWebResponse = null;
            HttpWebRequest = WebRequest.Create(url);
            HttpWebResponse = HttpWebRequest.GetResponse();

            //獲得流
            sr = new StreamReader(HttpWebResponse.GetResponseStream(), code);
            strHtml = sr.ReadToEnd();

            //寫入文件
            try
            {

                if (!Directory.Exists(fna)) 
                {
                    Directory.CreateDirectory(fna); 
                }
                sw = new StreamWriter(fna+"\\"+fileName, false, code);
                sw.WriteLine(strHtml);
                sw.Flush();
                ok = true;
            }
            catch (Exception ex)
            {
                ok = false;
            }
            finally
            {
                if (sw != null)
                {
                    sw.Close();
                }
            }
            return ok;
        }
    }
