The remote server returned an error: (400) Bad Request - uploading less 2MB file size?
- by fiberOptics
The file succeed to upload when it is 2KB or lower in size. The main reason why I use streaming is to be able to upload file up to at least 1 GB. But when I try to upload file with less 1MB size, I get bad request. It is my first time to deal with downloading and uploading process, so I can't easily find the cause of error.
Testing part:
private void button24_Click(object sender, EventArgs e)
{
try
{
OpenFileDialog openfile = new OpenFileDialog();
if (openfile.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
string port = "3445";
byte[] fileStream;
using (FileStream fs = new FileStream(openfile.FileName, FileMode.Open, FileAccess.Read, FileShare.Read))
{
fileStream = new byte[fs.Length];
fs.Read(fileStream, 0, (int)fs.Length);
fs.Close();
fs.Dispose();
}
string baseAddress = "http://localhost:" + port + "/File/AddStream?fileID=9";
HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(baseAddress);
request.Method = "POST";
request.ContentType = "text/plain";
//request.ContentType = "application/octet-stream";
Stream serverStream = request.GetRequestStream();
serverStream.Write(fileStream, 0, fileStream.Length);
serverStream.Close();
using (HttpWebResponse response = request.GetResponse() as HttpWebResponse)
{
int statusCode = (int)response.StatusCode;
StreamReader reader = new StreamReader(response.GetResponseStream());
}
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
Service:
[WebInvoke(UriTemplate = "AddStream?fileID={fileID}", Method = "POST", BodyStyle = WebMessageBodyStyle.Bare)]
public bool AddStream(long fileID, System.IO.Stream fileStream)
{
ClasslLogic.FileComponent svc = new ClasslLogic.FileComponent();
return svc.AddStream(fileID, fileStream);
}
Server code for streaming:
namespace ClasslLogic
{
public class StreamObject : IStreamObject
{
public bool UploadFile(string filename, Stream fileStream)
{
try
{
FileStream fileToupload = new FileStream(filename, FileMode.Create);
byte[] bytearray = new byte[10000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, 0, bytearray.Length);
totalBytesRead += bytesRead;
} while (bytesRead > 0);
fileToupload.Write(bytearray, 0, bytearray.Length);
fileToupload.Close();
fileToupload.Dispose();
}
catch (Exception ex) { throw new Exception(ex.Message); }
return true;
}
}
}

I'm not sure if this affects the streaming function, because I'm using WCF4.0 rest template
which config is dependent in Global.asax.
One more thing is this, whether I run the service and passing a stream or not, the created file always contain this thing.
How could I remove the "NUL" data?
Thanks in advance.
Edit
public bool UploadFile(string filename, Stream fileStream)
{
try
{
FileStream fileToupload = new FileStream(filename, FileMode.Create);
byte[] bytearray = new byte[10000];
int bytesRead, totalBytesRead = 0;
do
{
bytesRead = fileStream.Read(bytearray, totalBytesRead, bytearray.Length - totalBytesRead);
totalBytesRead += bytesRead;
} while (bytesRead > 0);
fileToupload.Write(bytearray, 0, totalBytesRead);
fileToupload.Close();
fileToupload.Dispose();
}
catch (Exception ex) { throw new Exception(ex.Message); }
return true;
}
