如何配置IIS6，让他能够下载源文件

Question

要配置一个纯粹保存文件的网站，如果上传的是asa、asp、config等扩展名的文件，都是不能下载的，提示403错误，我已经MIME里设置 .* 为 application/octet-stream了

Answer 1

可能要把原来扩展名的ISAPI删掉的，不然IIS还是会去解释的
楼主试试吧，记得备份一下~

Answer 2

删除完了以后，asp.net版本会回复的1.1，然后就自动还原了，我留了一个没删，这样就可以，凑合用了，问题解决了。谢谢

你可以在Global.asax里处理：        protected void Application_BeginRequest(object sender, EventArgs e)
        {
            string path = Server.MapPath(Request.Url.PathAndQuery);
            if (!string.IsNullOrEmpty(path))
            {
                string ext = Path.GetExtension(path);
                if (ext != ".asa" && ext != ".asp" && ext != ".config")
                {
                    ResponseFile(Request, Response, Path.GetFileName(path), path, 1024 * 1024);
                }
            }
        }        public static bool ResponseFile(HttpRequest _Request, HttpResponse _Response, string _fileName, string _fullPath, long _speed)
        {
            try
            {
                FileStream myFile = new FileStream(_fullPath, FileMode.Open, FileAccess.Read, FileShare.ReadWrite);
                BinaryReader br = new BinaryReader(myFile);
                try
                {
                    _Response.AddHeader("Accept-Ranges", "bytes");
                    _Response.Buffer = false;
                    long fileLength = myFile.Length;
                    long startBytes = 0;                    int pack = 10240;   //10K   bytes  
                    //int   sleep   =   200;   //每秒5次   即5*10K   bytes每秒  
                    int sleep = (int)Math.Floor(1000D * pack / _speed) + 1;
                    if (_Request.Headers["Range"] != null)
                    {
                        _Response.StatusCode = 206;
                        string[] range = _Request.Headers["Range"].Split(new char[] { '=', '-' });
                        startBytes = Convert.ToInt64(range[1]);
                    }
                    _Response.AddHeader("Content-Length", (fileLength - startBytes).ToString());
                    if (startBytes != 0)
                    {
                        _Response.AddHeader("Content-Range", string.Format("   bytes   {0}-{1}/{2}", startBytes, fileLength - 1, fileLength));
                    }
                    _Response.AddHeader("Connection", "Keep-Alive");
                    _Response.ContentType = "application/octet-stream";
                    _Response.AddHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(_fileName, System.Text.Encoding.UTF8));                    br.BaseStream.Seek(startBytes, SeekOrigin.Begin);
                    int maxCount = (int)Math.Floor((double)(fileLength - startBytes) / pack) + 1;                    for (int i = 0; i < maxCount; i++)
                    {
                        if (_Response.IsClientConnected)
                        {
                            _Response.BinaryWrite(br.ReadBytes(pack));
                            Thread.Sleep(sleep);
                        }
                        else
                        {
                            i = maxCount;
                        }
                    }
                }
                catch
                {
                    return false;
                }
                finally
                {
                    br.Close();
                    myFile.Close();
                }
            }
            catch
            {
                return false;
            }
            return true;
        }
光靠配置IIS我没想到好办法

Answer 4

我也没试过，呵呵，只知道那个是负责解释的，5楼的办法也很好，写文件，这样不用动IIS的配置，省去了很多麻烦

Answer 5

还是在前面加一个简单的壳吧。GetFile.ashxcontext.Response.WriteFile(context.Server.MapPath(context.Request.QueryString["path"]));
