将聊天服务器实现为WebService [英] Implementing a chat server as a WebService

问题描述

我有一个学校项目，我必须实现一个聊天应用程序，其服务器将是一个java Web服务。

I have a school project in which I have to implement a chat application, whose server will be a java web service.

问题是我一直都是将Web服务视为一种调用远程功能的方式，我不知道如何在Web服务上保持会话活动，也不知道如何跟踪当前聊天，房间等所有人。

The problem is that I've always thought of a web service as a way of calling remote functions, and I have no idea how to keep a "session" active on the web service, nor how to keep track of all the people currently in chat, rooms etc.

推荐答案

据我所知，聊天服务器应该在初始连接后知道其客户端，并将每个客户端消息发送给所有客户端客户端。这肯定需要某种会话维护。我认为正确的方法如下：

To the best of my knowledge, a chat server is supposed to know its clients after an initial connection, and send every client message to all clients. This definitely calls for some sort of session maintenance. I think the right way to do this is as follows:

1. 客户端调用Web服务'握手'并提供一些最小的识别细节。


2. 服务器返回包含唯一客户端标识符的确认。


3. 客户端调用Web服务消息并发送新消息及其标识符。


4. 服务器通过标识符识别客户端，将消息分发给所有客户端。

1. Client calls web service 'handshake' and provides some minimal identification details.
2. Server returns an acknowledgment that includes a unique client identifier.
3. Client calls web service 'message' and sends a new message, together with its identifier.
4. Server identifies client by the identifier, distributes message to all clients.

我不是确实消息分发应该如何工作，因为Web服务本质上是一种拉服务而不是推送。也许客户端应该为服务器公开自己的Web服务。

I'm not really sure how the message distribution should work, as web services are essentially a pull-service and not push. Perhaps the client should expose its own web service for the server to call.
