Question

我不确定从哪里开始，到目前为止，我已经将它用于服务器端：

public static void main (String[] args) throws java.lang.Exception
{
    String ad ="1<2";
    ScriptEngineManager manager = new ScriptEngineManager();
    ScriptEngine engine = manager.getEngineByName("js");
    Object result = engine.eval(ad);
    System.out.println(Boolean.TRUE.equals(result)); // true
}

这对于客户端来说：

 # Server program
 from socket import *
 import time
 import sys

 serverhost = '127.0.0.1'
 serverport = 5005
 buffersize = 2048

 serversock = socket(AF_INET,SOCK_DGRAM)

 serveraddr = (serverhost, serverport)
 serversock.bind(serveraddr)
 print 'Server is ready to receive'

 while True:
    try:
            message, clientaddr = serversock.recvfrom(buffersize)
            print 'Server received ', message, 'from ', str(clientaddr)


            print "Server sending back " + str(message)
            serversock.sendto(message, clientaddr)

    except:
            print 'Exception occured, closing socket'
            break

   serversock.close()

到目前为止，我不确定TCP标头是否正确，但如何开始消息交换？它应该是通过UDP发送具有TCP功能的数据包。我该如何开始连接（三次握手）？

使用TCP功能实现UDP
