在这个示例中,我们维护了一个websockets列表来跟踪所有活动的WebSocket连接。每次有新的客户端连接时,我们都会将其添加到这个列表中。 当服务端想要主动推送消息时,可以调用send_message_to_all函数,并将消息发送给所有连接的客户端。 测试WebSocket服务: 创建一个简单的HTML页面来测试WebSocket连接: html <!DOCTYP...

The client sends information to websocket and makes it wait for 30 seconds at the server The client is sending the HTTP request. At this time, the HTTP request will be in pending, and it will not continue to process until the websocket wait ends for 30 seconds ...
send_personal_message: 向特定客户端发送私密消息。 update_chat_pairs: 更新客户端之间的聊天关系,以便双方能够继续通信。 WebSocket 端点: 定义了一个 WebSocket 路由(/ws/{client_id}),用于处理客户端连接、消息接收与发送。 每当客户端发送消息时,系统会解析消息的目标客户端,并通过ConnectionManager将消息发送给...
