java传输的zip文件流，VB.NET端得不到

Question

如题：要做一个自动更新程序。
现在遇到的问题是，从java服务器端发送压缩包流，vb.net端得到流偏小。
试了传输txt，jpg都没有问题。

java代码
@RequestMapping(value = "/getProgram")
public void getProgram(HttpServletRequest req, HttpServletResponse res) {
try {
FileInputStream fis = new FileInputStream("d://bbb.zip");
byte[] buf=new byte[fis.available()];
fis.read(buf);
fis.close();

// res.setCharacterEncoding("UTF-8");
res.setContentType("application/ostet-stream");
res.setContentLength(buf.length);
OutputStream os = res.getOutputStream();
os.write(buf);
os.flush();

os.close();

    } catch (Exception e) {
        logger.error(e.getMessage());
    }
}

VB.NET 代码
    Public Sub PostData2(ByVal url As String)

    Try
        ServicePointManager.Expect100Continue = False
        Dim request As HttpWebRequest = WebRequest.Create(url)
        request.Method = "POST"
        request.ContentType = "application/ostet-stream"
        request.GetRequestStream()

        Dim stream As Stream = request.GetResponse().GetResponseStream()
        Dim zipPath As String = programPath + "\aaa.zip"
        Dim streamReader As New StreamReader(stream)
        Dim sw As StreamWriter = New StreamWriter(zipPath, False, New UTF8Encoding(False))

        Dim buffer() As Byte = Encoding.ASCII.GetBytes(streamReader.ReadToEnd)
        sw.Write(System.Text.Encoding.UTF8.GetString(buffer))

        'For i As Integer = 0 To buffer.Length - 1
        '    sw.Write(buffer(i))
        'Next

        'sw.Write(streamReader.ReadToEnd)

        sw.Flush()
        sw.Close()
        stream.Dispose()
        stream.Close()

    Catch ex As Exception
        setLog("PostData"， ex.Message)
    End Try
End Sub

你确定是post么，java的代码看上去是get
