客户端套接字维护队列/池
我正在尝试创建客户端套接字连接，当创建新请求时，会建立连接并建立连接。发生数据传输。有什么方法可以让连接创建后就一直打开吗？如果是，那么如何创建它&另外我如何识别发送了什么请求？得到相同请求的响应吗？
期待您的回复。
I am trying to create a client socket connection, when a new request is created a connection is established & data transfer takes place. Is there any way that once the Connection is created it will be open for all time ? If yes then how can create it & also how can I identify what request is sent & got the response for the same request?
Looking forward for your response.

您可以一直创建连接，但不关闭它。然而，诀窍是检测连接何时失败。例如，客户端/服务器已重新启动。
如果你想将请求与响应匹配，你可以使用请求 ID，但一种更简单的方法是每个套接字一次只发送一个请求，这样你得到的响应就是你刚刚发送的请求。如果需要，您可以在一个线程中使用多个套接字。
You can create a connection for all time, by not closing it. However the trick is detecting when a connection has failed. e.g. the client/server has restarted.
If you want to match requests to responses you can use a request id, but a much simpler approach is to only send one request at a time per socket, that way the response you get is for the request you just sent. You can use more than one socket in a thread if this is required.
