Java套接字编程-请求

Question

I am writing a messaging application in java using sockets and currently the server will wait for a request and just automatically accept it:

ServerSocket s = new ServerSocket(1254);
Socket s1 = s.accept();

If there any way in which I can detect requests to the server and allow the server to only accept certain requests?

Answer 1

我不清楚您对“某些请求”的含义，但是您可以接受它，对其进行验证，如果不是“某些请求”，则只需断开连接。

Answer 2

AFAIK there is no way that you can deny request without accepting it, (until and unless you have some reverse proxy setup like nginx).

After accepting the socket you can check out the various parameters for example Socket's remote address (check for more info java.net.Socket ), and close the socket if you don't want the connection to be established.
