它在客户端代码的最后一行中出现错误,并带有代码。 java.io.StreamCorruptedException:无效的流标题:36353137.在这之前,我还没有对流做过任何事情,所以我不确定可能导致ObjectInputStream的问题。损坏的inputStream
服务器类正常工作,并遵循我为它设置的行为,它只是客户端类错误。
我以为这个问题起初可能是因为流没有被刷新,但是刷新并没有解决问题。
除此之外,由于此错误在代码的早期发生,因此我无法确定要添加哪些内容来修复它。
客户端类 -

import java.net.*;
public class tcpClient {
int nonce;
Socket requestSocket;
ObjectOutputStream out;
ObjectInputStream in;
String message;

System.out.println("Connected to localhost in port 3223");
out = new ObjectOutputStream(requestSocket.getOutputStream());
out.flush();
in = new ObjectInputStream(requestSocket.getInputStream());
