关于页面有参数时上载文件总是调用迅雷上载aspx页面
关于页面有参数时下载文件总是调用迅雷下载aspx页面
我的下载方法如下:
public static void down(string filePath)
{
FileInfo DownloadFile = new FileInfo(filePath);
HttpContext.Current.Response.Clear();
HttpContext.Current.Response.ContentType = "application/octet-stream";
HttpContext.Current.Response.AppendHeader("Content-Disposition", "attachment;filename=" + HttpUtility.UrlEncode(DownloadFile.Name, Encoding.UTF8));
HttpContext.Current.Response.AppendHeader("Content-Length", DownloadFile.Length.ToString());
HttpContext.Current.Response.WriteFile(DownloadFile.FullName);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
}
方法本身没有问题,如果这个页面没有参数,直接调用就没事,即使调用迅雷也是下载原来的文件,但如果页面有参数,就会导致调用迅雷把这个页面给下载下来,后缀是.aspx
找了半天原因才发现是页面参数捣的鬼,问下各位高手有什么解决办法么?我不想用a连接或这直接Response.Redirect

- C# code
//TransmitFile实现下载 protected void Button1_Click(object sender, EventArgs e) { Response.ContentType = "application/x-zip-compressed"; Response.AddHeader("Content-Disposition", "attachment;filename=z.zip"); string filename = Server.MapPath("DownLoad/z.zip"); Response.TransmitFile(filename); } //WriteFile实现下载 protected void Button2_Click(object sender, EventArgs e) { string fileName ="asd.txt";//客户端保存的文件名 string filePath=Server.MapPath("DownLoad/aaa.txt");//路径 FileInfo fileInfo = new FileInfo(filePath); Response.Clear(); Response.ClearContent(); Response.ClearHeaders(); Response.AddHeader("Content-Disposition", "attachment;filename=" + fileName); Response.AddHeader("Content-Length", fileInfo.Length.ToString()); Response.AddHeader("Content-Transfer-Encoding", "binary"); Response.ContentType = "application/octet-stream"; Response.ContentEncoding = System.Text.Encoding.GetEncoding("gb2312"); Response.WriteFile(fileInfo.FullName); Response.Flush(); Response.End(); } //WriteFile分块下载 protected void Button3_Click(object sender, EventArgs e) { string fileName = "aaa.txt";//客户端保存的文件名 string filePath = Server.MapPath("DownLoad/aaa.txt");//路径 System.IO.FileInfo fileInfo = new System.IO.FileInfo(filePath); if (fileInfo.Exists == true) { const long ChunkSize = 102400;//100K 每次读取文件,只读取100K,这样可以缓解服务器的压力 byte[] buffer = new byte[ChunkSize]; Response.Clear(); System.IO.FileStream iStream = System.IO.File.OpenRead(filePath); long dataLengthToRead = iStream.Length;//获取下载的文件总大小 Response.ContentType = "application/octet-stream"; Response.AddHeader("Content-Disposition", "attachment; filename=" + HttpUtility.UrlEncode(fileName)); while (dataLengthToRead > 0 && Response.IsClientConnected) { int lengthRead = iStream.Read(buffer, 0, Convert.ToInt32(ChunkSize));//读取的大小 Response.OutputStream.Write(buffer, 0, lengthRead); Response.Flush(); dataLengthToRead = dataLengthToRead - lengthRead; } Response.Close(); } }

方法一:点击保存后在弹出页面选择使用IE下载
方法二: 把迅雷中的设置--高级 --监视浏览器的勾去掉
再有就是试试压缩下载看行不行
