nio服务器图片显示,NIO服务器/客户端发送图像问题

嗨，我一直在努力制作NIO服务器/客户端程序。 我的问题是，服务器只发送14个字节，那么它不会再发送任何东西。我坐在这，我真的什么都看不到了，并为此这么久决定，看是否有人在这里可以看到问题NIO服务器/客户端发送图像问题

服务器代码：

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();

}

}

}

客户：

import java.io.IOException;

import java.net.InetSocketAddress;

import java.nio.ByteBuffer;

import java.nio.channels.Channels;

import java.nio.channels.ReadableByteChannel;

import java.nio.channels.SocketChannel;

import java.nio.channels.WritableByteChannel;

import java.io.*;

import java.net.*;

import java.nio.*;

import java.nio.channels.*;

import java.nio.charset.*;

public class Testclient {

public static void main(String[] args) throws IOException {

SocketChannel socket = SocketChannel.open(new InetSocketAddress(8888));

FileOutputStream out = new FileOutputStream("C:\taemot\picNIO.png");

FileChannel file = out.getChannel();

ByteBuffer buffer = ByteBuffer.allocateDirect(8192);

while(socket.read(buffer) != -1) {

buffer.flip();

file.write(buffer);

buffer.compact();

buffer.clear();

}

socket.close();

file.close();

out.close();

}

}
