由于某些原因，我需要通过服务器套接字分别发送多个字节数组，客户端套接字将接收这些字节数组。在发送字节数组后，我发现在客户端套接字中接收的字节数组不等于服务器套接字中的字节数组。如果我使用ObjectOutputStream和ObjectInputStream，那么一切正常，但是根据我的需要，我不能使用ObjectOutputStream＆amp; ObjectInputStream，因为我的服务器需要连接两个以上的套接字。
这是服务器和客户端代码：
服务器（发送器）：
private void sendData() throws IOException {
DataOutputStream outputStream = new DataOutputStream(new BufferedOutputStream(socket.getOutputStream()));
File file = new File(filePath);
byte[] fileByte = new byte[(int) file.length()];
// Convert file into byte array
FileInputStream fileInputStream = new FileInputStream(file);
fileInputStream.read(fileByte);
while (!decoder.isDecoded()) {
byte[] packet = new byte[encoder.getPacketLength()];
encoder.getPacket(packet, 0);
if (Math.random() < 0.1)
continue;
// Send data HERE!!!
outputStream.writeInt(encoder.getPacketLength());
outputStream.write(packet);
StringBuilder sb = new StringBuilder();
for (byte value : packet) {
sb.append(value);
}
serverLog("Packet content= " + sb.toString());
decoder.addPacket(packet, 0);
}
outputStream.close();
outputStream.flush();
fileInputStream.close();
}
客户端（接收器）：
public void receiveData() throws UnknownHostException, IOException, ClassNotFoundException {
in = new BufferedReader(new InputStreamReader(socket.getInputStream()));
DataInputStream dis = new DataInputStream(new BufferedInputStream(socket.getInputStream()));
int len = dis.readInt();
while (!decoder.isDecoded()) {
byte[] packet = new byte[len];
dis.read(packet, 0, len);
StringBuilder sb = new StringBuilder();
for (byte value : packet) {
sb.append(value);
}
messageArea.append("Packet content= " + sb.toString() + "\n");
decoder.addPacket(packet, 0);
}
}

每个人都可以看到总共有6个整数＆＃34; 000110＆＃34;在第一个数据包之后插入接收到的数据包，如何编辑这些代码以防止此问题并确保发送的数据包和接收的数据包相等？请帮帮我，谢谢你的帮助。 ：）
答案 0 :(得分：0)
您假设read()填充缓冲区，而不检查返回值。没有指定这样做，只传输至少一个字节。使用readFully()来获取该行为。
