Question

给位大虾，怎样将指定的动态页面保存到本地，包括图片，是用asp。net实现的，小弟先谢谢各位大虾了。

Answer 1

可以用采集获取图片和html,如果是aspx要用流输出using System;
using System.Data;
using System.IO;
using System.Configuration;
using System.Collections;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;public partial class down : NetCMS.Web.UI.BasePage
{
    protected void Page_Load(object sender, EventArgs e)
    {
        if (!Page.IsPostBack)
            getDownInfo();
    }    /// <summary>
    /// 获取新闻附件下载信息
    /// </summary>
    protected void getDownInfo()
    {
        string id =Request.QueryString["id"];
        if (id != null && id != "")
        {
            NetCMS.Content.ContentManage news = new NetCMS.Content.ContentManage();
            string DownAdress = news.getNewsAccessory(int.Parse(id)).ToLower();
            DownAdress = DownAdress.Replace("{@dirfile}", NetCMS.Config.UIConfig.dirFile);
            DownAdress = DownAdress.Replace("{@dirtemplet}", NetCMS.Config.UIConfig.dirTemplet);
            string dimm = NetCMS.Config.UIConfig.dirDumm;
            if (dimm.Trim() != string.Empty)
            {
                dimm = "/" + dimm;
            }
            
            DownAdress = dimm + DownAdress;
            using (FileStream fso = new FileStream(Server.MapPath(DownAdress), FileMode.Open,FileAccess.Read,FileShare.Read))
            {
                string[] filename=DownAdress.Split(new char[]{'/'});
                int len = Convert.ToInt32(fso.Length);
                byte[] FileObj = new byte[len];
                fso.Read(FileObj, 0, len);
                Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", HttpUtility.UrlEncode(filename[filename.Length - 1]), System.Text.Encoding.UTF8));
                Response.AddHeader("Content-Length", len.ToString());
                Response.ContentType = "application/octet-stream";
                Response.Charset = "UTF-8";
                Response.ContentEncoding = System.Text.Encoding.UTF8; 
                Response.BinaryWrite(FileObj);
                Response.Flush();
                Response.Clear();
                fso.Close();
            }
            //Response.Write("<script langauge=\"javascript\">self.location='" + DownAdress + "';</script>");
            //Response.End();
        }
        else
        {
            Err();
        }
    }    protected void Err()
    {
        Response.Write("<script language=\"javascript\">alert('参数传递错误!');history.back();</script>");
        Response.End();
    }
}

你的意思就是要个另存为？？
//用这段。。把它下载下来///   <summary> 
///   文件下载 
///   </summary> 
///   <param   name= "FullFileName "> </param> 
private   void   FileDownload(string   FullFileName) 
{ 
FileInfo   DownloadFile   =   new   FileInfo(FullFileName);   
Response.Clear(); 
Response.ClearHeaders(); 
Response.Buffer=false; 
Response.ContentType= "application/octet-stream "; 
Response.AppendHeader( "Content-Disposition ", "attachment;filename= "   +HttpUtility.UrlEncode(DownloadFile.FullName,System.Text.Encoding.UTF8)); 
Response.AppendHeader( "Content-Length ",DownloadFile.Length.ToString()); 
Response.WriteFile(DownloadFile.FullName); 
Response.Flush(); 
Response.End(); 
}

Answer 3

是的，意思就下要把一个指定的网页以HTML的格式保存到本地，我自己做的是只能保存静态的东西，动态的是不能显示的。你给的这个方法的话好像不支持url格式的参数的，小弟是菜鸟，还请各位大虾多多帮助。

            return retValue;
        }
    }}

谢谢liuchaolin，这种方法我也试了，但是对于动态的的数据还是读不出，例如那些动态生成的导航和图片

Answer 6

是因为缓存问题，你要在采集的文件名后加随机数参数如abc.aspx?abc=13123(随机生成)
