嗨,我一直在努力製作NIO服務器/客戶端程序。 我的問題是,服務器只發送14個字節,那麼它不會再發送任何東西。我坐在這,我真的什麼都看不到了,併爲此這麼久決定,看是否有人在這裏可以看到問題NIO服務器/客戶端發送圖像問題
服務器代碼:
import java.nio.*;
import java.nio.channels.*;
import java.nio.charset.*;
public class Testserver {
public static void main(String[] args) throws java.io.IOException {
ServerSocketChannel server = ServerSocketChannel.open();
server.socket().bind(new java.net.InetSocketAddress(8888));
for(;;) {
// Wait for a client to connect
SocketChannel client = server.accept();
String file = ("C:\\ftp\\pic.png");
ByteBuffer buf = ByteBuffer.allocate(1024);
while(client.read(buf) != -1){
buf.clear();
buf.put(file.getBytes());
buf.flip();
client.write(buf);
// Disconnect from the client
}
client.close();
}
}
}
