Websocket直接域名连接

  • Websocket使用 ws 或 wss 的统一资源标志符,类似于 HTTP 或 HTTPS,其中 wss 表示在 TLS 之上的 Websocket ,相当于 HTTPS 了。
  • 默认情况下,Websocket 的 ws 协议使用 80 端口;运行在TLS之上时,wss 协议默认使用 443 端口。其实说白了,wss 就是 ws 基于 SSL 的安全传输,与 HTTPS 一样样的道理
配置Nginx支持wss
# 我的配置在https的nginx下面
        location /usign {
                proxy_pass http://127.0.0.1:9990/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_set_header Host $host;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header REMOTE-HOST $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                client_max_body_size 5000M;
        }

代码中的使用

vue中配置
  • 我这里用在了vue里面,工程使用的脚手架。websocket用在了app.vue里面,因为我的是全局的监听。从服务器上面回来的数据,可以通过vue的store来改变其他页面的数据
<script>
import { mapState, mapMutations } from 'vuex'
export default {
  name: 'App',
  data () {
    return {
      websock: null,
      reconnectData: null,
      lockReconnect: false,
      timeout: 10000,
      timeoutObj: null,
      serverTimeoutObj: null
    }
  },
  computed: {
    ...mapState([
      'currentUser',
      'identificationDevice',
      'logshow'
    ])
  },
  created () {
    document.title = ''
    this.initWebSocket()
  },
  methods: {
    ...mapMutations([
      'updatePromptBtn',
      'updateIpaName'
    ]),
    initWebSocket () {
      if (this.websock !== null) {
        this.websock.close()
        this.websock = null
      }
      let wsurl = ''
      if (this.baseUrl.indexOf('192') === -1) {
        let url = this.baseUrl.substr(this.baseUrl.indexOf('www'))
        wsurl = 'wss://' + url + '/websocket'
      } else {
        let url = this.baseUrl.substr(this.baseUrl.indexOf('192'))
        wsurl = 'ws://' + url + '/websocket'
      }
      if (this.logshow) {
        console.log('启动中' + wsurl)
      }
      this.websock = new WebSocket(wsurl)
      this.websock.onopen = this.websocketonopen
      this.websock.onmessage = this.websocketonmessage
      this.websock.onerror = this.websocketonerror
      this.websock.onclose = this.websocketclose
    },
    websocketonopen () {
      if (this.logshow) {
        console.log('连接成功')
      }
      this.heartBeat()
    },
    websocketonerror () {
      if (this.logshow) {
        console.log('连接失败')
      }
      this.reconnect()
    },
    websocketclose () {
      if (this.logshow) {
        console.log('断开连接')
      }
      this.reconnect()
    },
    websocketonmessage (msg) {
      let data = JSON.parse(msg.data)
      if (data.type === 'heartBeat') {
        if (this.logshow) {
          console.log('收到心跳回复:' + data.type)
        }
        this.heartBeat()
      }
      if (this.currentUser === undefined || this.currentUser == null) {
        return
      }
      if (this.identificationDevice !== data.identificationDevice) {
        if (this.logshow) {
          console.log('收到不是自己的:from', data.identificationDevice)
        }
        return
      }
      if (this.logshow) {
        console.log('收到消息: ' + msg.data)
      }
      // 这里定义自己的逻辑
    },
    websocketsend (data) {
      this.websock.send(JSON.stringify(data))
    },
    reconnect () {
      if (this.lockReconnect) {
        return
      }
      this.lockReconnect = true
      this.reconnectData && clearTimeout(this.reconnectData)
      this.reconnectData = setTimeout(() => {
        this.initWebSocket()
        this.lockReconnect = false
      }, 5000)
    },
    heartBeat () {
      this.timeoutObj && clearTimeout(this.timeoutObj)
      this.serverTimeoutObj && clearTimeout(this.serverTimeoutObj)
      this.timeoutObj = setTimeout(() => {
        this.websocketsend({ type: 'heartBeat' })
        this.serverTimeoutObj = setTimeout(() => {
          this.websock.close()
        }, 5000)
      }, this.timeout)
    }
  },
  destroyed () {
    this.lockReconnect = true
    this.websock.close()
    clearTimeout(this.reconnectData)
    clearTimeout(this.timeoutObj)
    clearTimeout(this.serverTimeoutObj)
  }
}
</script>
Java中配置
  • 1、引入依赖
<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-websocket</artifactId>
</dependency>
  • 2、添加WebSocketConfig
/**
 * 开启WebSocket支持
 */
@Configuration
public class WebSocketConfig {
    @Bean
    public ServerEndpointExporter serverEndpointExporter() {
        return new ServerEndpointExporter();
    }
}
  • 3、写服务类WebSocketServer
@ServerEndpoint("/websocket")
@Component
public class WebSocketServer extends BaseService{

    static Log log=LogFactory.get(WebSocketServer.class);
    private static CopyOnWriteArraySet<WebSocketServer> webSocketServers = new CopyOnWriteArraySet<>();
    private Session session;

    /**
     * 连接建立成功调用的方法*/
    @OnOpen
    public void onOpen(Session session) {
        this.session = session;
        webSocketServers.add(this);
        try {
            sendMessage("与后端连接成功");
        } catch (IOException e) {
            log.error("网络异常!!!!!!");
        }
    }

    /**
     * 连接关闭调用的方法
     */
    @OnClose
    public void onClose() {
        log.info("连接关闭");
        webSocketServers.remove(this);
    }

    /**
     * 收到客户端消息后调用的方法
     *
     * @param message 客户端发送过来的消息*/
    @OnMessage
    public void onMessage(String message) throws IOException {
        log.info("报文:"+message);
        JSONObject jsonObject = JSON.parseObject(message);
        Object type = jsonObject.get("type");
        if (type != null && type.equals("heartBeat")) {
            sendMessage(message);
        }
    }

    /**
     *
     * @param session
     * @param error
     */
    @OnError
    public void onError(Session session, Throwable error) {
        log.error("onError原因:"+error.getMessage());
        error.printStackTrace();
    }
    /**
     * 实现服务器主动推送
     */
    public void sendMessage(String message) throws IOException {
        this.session.getBasicRemote().sendText(message);
    }


    /**
     * 发送自定义消息
     * */
    public static void sendInfo(Map message) throws IOException {
        String msg = JSON.toJSONString(message);
        log.info("发送消息报文:" + msg);
        for (WebSocketServer webSocketServer:webSocketServers) {
            webSocketServer.sendMessage(msg);
        }
    }
}
  • 4、在需要的地方发送消息
@GetMapping(value = "/update/config")
    public RestResponse updateMobileconfig(
            @RequestParam String key,
            @RequestParam String type,
            @RequestParam String identificationDevice
    ) throws IOException {
        Map<String, String> map = new HashMap();
        map.put("identificationDevice", identificationDevice);
        map.put("key", key);
        map.put("type", type);
        WebSocketServer.sendInfo(map);
        return RestResponse.success();
    }
以上都是简单的使用,如果对你有用这是最好
