HTTP GET用空体来响应，在IE下载excel文件
我试图找出当我下载一个Excel报告时，在这个页面上发生了什么。 它只适用于Internet Explorer，当我尝试使用ScalaJ在Scala中下载报告时，响应正文的inputstream为空。 有人能帮我理解这里发生了什么吗？
明文请求：
GET /oca_ReportViewer.aspx?ReportName=District_and_Statutory_County_Court/DSC_Civil_Family_Activity_Detail_N.rpt&ddlFromMonth=9&ddlFromYear=2010&txtFromMonthField=@FromMonth&txtFromYearField=@FromYear&ddlToMonth=10&ddlToYear=2010&txtToMonthField=@ToMonth&txtToYearField=@ToYear&ddlCountyPostBack=0&txtCountyPostBackField=@CountyID&chkAggregateMonthlyReport=0&export=1625 HTTP/1.1 Accept: text/html, application/xhtml+xml, image/jxr, */* Referer: http://card.txcourts.gov/ReportSelection.aspx Accept-Language: en-US User-Agent: Mozilla/5.0 (Windows NT 10.0; WOW64; Trident/7.0; rv:11.0) like Gecko Accept-Encoding: gzip, deflate Host: card.txcourts.gov Connection: Keep-Alive Cache-Control: no-cache Cookie: ASP.NET_SessionId=j0tgci45qj3t1uqygrvkqz55 到目前为止的代码：

如果有人能帮助我，我将不胜感激！ 我只需要将响应保存到.xls文件。 如果你有时间的话，我也无法find浏览器正在提取会话ID的位置，所以这也是很有帮助的。
编辑：
我可以看到，Excel数据实际上是发送，检查出这个stream遵循使用wireshark：
谢谢！
好吧，不太确定为什么我的stream是空的，但我改变了代码，只是closures输出stream，当它的exception。 我知道这是愚蠢的，但它的工作和文件下载完全。 如果其他人知道更好的解释，我会很感激！
这是新的parsing函数：
def parse(status: Int, headers: Map[String, IndexedSeq[String]], inputStream: InputStream): Unit = { val output = new BufferedOutputStream(new FileOutputStream(filename)) try { Iterator .continually (inputStream.read) .takeWhile (-1 !=) .foreach (output.write) } catch { case _: Throwable => output.close() } finally{ output.close() } }
