Question

我的项目有问题。我有一些下载内容的代码：.doc，.zip等

在版本12的chrome更新之前它工作正常，之后浏览器显示错误消息：“Download Interrupted”。

我已经在其他浏览器（Chrome 11，FF和IE8）中测试过，一切正常。

代码示例是：

HttpContext.Current.Response.Clear();
HttpContext.Current.Response.AppendHeader("Content-Type", "application/msword");
HttpContext.Current.Response.AppendHeader("Content-disposition", "attachment; filename=" + filename + ".doc");
HttpContext.Current.Response.AppendHeader("Content-Transfer-Encoding", "binary");
HttpContext.Current.Response.Write(strBody);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.Close();

有人知道会发生什么或我如何解决这个问题？

Answer 1

根据this forum中的回答，添加Response.End()解决了问题。

在你的情况下，它将是

HttpContext.Current.Response.Write(strBody);
HttpContext.Current.Response.Flush();
HttpContext.Current.Response.End();
HttpContext.Current.Response.Close();

Answer 2

我使用此代码从sql server数据库获取二进制数据，它可以在所有浏览器中使用;

        DataTable table = SiteFileAccess.GetDataByFileID(fileId);
        byte[] b = (byte[])table.Rows[0]["FileData"];
        Response.Clear();
        Response.AddHeader("Content-Disposition", "attachment; filename=" + table.Rows[0]["FileName"].ToString());
        Response.AddHeader("Content-Length", b.Length.ToString());
        Response.ContentType = "application/octet-stream";
        Response.BinaryWrite(b);
        Response.Flush();
        Response.End();

请参阅上面的代码并根据您的需要进行修复。如果您需要更多信息，请告诉我

string applicationName = Session [“ApplicationName_UtilityDetail”]。ToString（）;

    HttpWebRequest objRequest = (HttpWebRequest)WebRequest.Create(Session["DownloadLink_UtilityDetail"].ToString());
    HttpWebResponse objResponse = (HttpWebResponse)objRequest.GetResponse();
    int bufferSize = 1;
    Response.Clear();
    Response.ClearHeaders();
    Response.ClearContent();
    Response.AppendHeader("Content-Disposition:", "attachment; filename=" + applicationName + ".zip");
    Response.AppendHeader("Content-Length", objResponse.ContentLength.ToString());
    Response.ContentType = "application/download";
    byte[] byteBuffer = new byte[bufferSize + 1];
    MemoryStream memStrm = new MemoryStream(byteBuffer, true);
    Stream strm = objRequest.GetResponse().GetResponseStream();
    byte[] bytes = new byte[bufferSize + 1];
    while (strm.Read(byteBuffer, 0, byteBuffer.Length) > 0)
    {
        Response.BinaryWrite(memStrm.ToArray());
        Response.Flush();
    }
    Response.Close();
    Response.End();
    memStrm.Close();
    memStrm.Dispose();
    strm.Dispose();

尝试一下：

Response.Buffer = true;
Response.Clear();
Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet";
Response.AddHeader("Content-Disposition", "attachment; filename=yourExcelFileName.xlsx;");
Response.BinaryWrite(yourByteArray);
Response.End();
