Java后端使用socketio,实现小程序答题pk功能

在使用socket.io跟前端通信过程中,出现了一系列问题,现做下记录。

一、功能需求是,在小程序端,用户可相互邀请,进入房间后进行答题PK。实现方法是,用户点击邀请好友,建立连接,查询当前是否有房间,有房间发送消息给两人,匹配成功,开始pk。没有房间新建房间返回,等待20秒,等待别人匹配。

代码如下,先看配置,在application.yml配置文件中增加如下配置

1 # host在本地测试可以设置为localhost或者本机IP,在Linux服务器跑可换成服务器IP 2 socketio: 3 host: 127.0.0.1 #监听的ip 4 port: 9999 #监听端口 5 # 设置最大每帧处理数据的长度,防止他人利用大数据来攻击服务器 6 maxFramePayloadLength: 1048576 7 # 设置http交互最大内容长度 8 maxHttpContentLength: 1048576 9 # socket连接数大小(如只监听一个端口boss线程组为1即可) 10 bossCount: 1 11 workCount: 100 12 allowCustomRequests: true 13 # 协议升级超时时间(毫秒),默认10秒。HTTP握手升级为ws协议超时时间 14 upgradeTimeout: 1000000 15 # Ping消息超时时间(毫秒),默认60秒,这个时间间隔内没有接收到心跳消息就会发送超时事件 16 pingTimeout: 6000000 17 # Ping消息间隔(毫秒),默认25秒。客户端向服务器发送一条心跳消息间隔 18 pingInterval: 25000 复制代码

二、遇到的一些问题

1、最初在发送消息给两人时,有个人能收到消息,有个人收不到

刚开始clientMap是这样声明的:

private static Map<String, SocketIOClient> clientMap = new ConcurrentHashMap<>();

但我在查询用户SocketIOClient时使用的是long类型,所以一直没查到用户的SocketIOClient,也就发送消息发不过去。

后面改为

private static Map<Long, SocketIOClient> clientMap = new
ConcurrentHashMap<>();

这样声明还是获取不到,继而检查代码,开始返回给两个人的信息对象JSONObject,使用的同一个对象,虽然重新set了值,但还是返回了相同的对象。

1 JSONObject jsonObject = new JSONObject(); 2 jsonObject.put("state" , 1); 3 jsonObject.put("wxUserInfo" , invite); 4 jsonObject.put("questions" , questions); 5 jsonObject.put("pkId" , pkGroup.getId()); 6 client.sendEvent("ConnectReceive",jsonObject); 7 SocketIOClient socketIOClient = clientMap.get(inviteUsrEntId); 8 WxUserInfo accept = wxUserInfoMapper.queryWxUserInfoByUsrEntId(usrEntId); 9 jsonObject.put("state" , 1); 10 jsonObject.put("questions" , questions); 11 jsonObject.put("pkId" , pkGroup.getId()); 12 jsonObject.put("wxUserInfo" , accept); 13 socketIOClient.sendEvent("ConnectReceive" , jsonObject); 复制代码

后改为重新new一个JSONObject对象,问题解决。

2、本地测试没问题,上了测试环境出现问题。连接时间超过1分钟,会自动断开连接。

后经查是服务器使用了nginx,nginx默认连接60s会断开连接。

需更改nginx配置,如下:

1 location /socket.io { 2 proxy_pass http://172.17.0.2:9999; 3 proxy_set_header Host $host; 4 proxy_next_upstream off; 5 proxy_buffering off; 6 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 7 8 proxy_http_version 1.1; 9 proxy_set_header Upgrade $http_upgrade; 10 proxy_set_header Connection "upgrade"; 11 proxy_read_timeout 3600s; 12 } 复制代码

proxy_read_timeout默认为60s,若需要长时间连接,改大点。

三、前端代码示例
