[英]Sending file in chunks in Java
I got this client application that sends my file fully to server. 我得到了这个客户端应用程序,可以将我的文件完全发送到服务器。 But I want it to send file in chunks.
但是我希望它以大块发送文件。 Here is my client code:
这是我的客户代码:
byte[] fileLength = new byte[(int) file.length()];
FileInputStream fis = new FileInputStream(file);
BufferedInputStream bis = new BufferedInputStream(fis);
DataInputStream dis = new DataInputStream(bis);
dis.readFully(fileLength, 0, fileLength.length);
OutputStream os = socket.getOutputStream();
//Sending size of file.
DataOutputStream dos = new DataOutputStream(os);
dos.writeLong(fileLength.length);
dos.write(fileLength, 0, fileLength.length);
dos.flush();
socket.close();
So how can I make client send my file in chunks? 那么,如何使客户端分块发送文件? Thanks in advance.
提前致谢。
Try to send the file from client in parts, something like 尝试部分地从客户端发送文件,例如
int count;
byte[] buffer = new byte[8192];
while ((count = in.read(buffer)) > 0)
{
out.write(buffer, 0, count);
}
and reassemble it on the server. 并在服务器上重新组装。
