我计划使用套接字（本地TCP）在两个进程（本地运行）之间进行通信。一个进程将充当服务器，但两个进程都异步地相互发送消息。我应该在进程的生命周期内保持套接字连接打开，还是为每个请求重新连接？
如果我保持本地套接字打开，是否会出现任何问题？
保持插座打开
这是一个更简单的选项，并且您不需要（从客户端的角度）打开一个新套接字或（从服务器的角度）接受一个新客户端的开销。
如果它只是一个客户端，那么您应该保持套接字打开，但要准备好在出现错误时重新连接（例如，用户可能已经重置了网络接口，因此不能保证连接是活动的）。如果您有许多客户端，请在非活动超时一定时间后使用断开连接。这将使您摆脱非活动、挂起或“丢失”的客户端（那些已经过去但没有关闭套接字的信号的客户端）。
