HarmonyOS 鸿蒙Next TCP Socket 连接自动断开

HarmonyOS 鸿蒙Next TCP Socket 连接自动断开

我按照开发文档写了tcp socket 连接，客户端打印的情况都是成功的，bind成功，connect成功，send成功。但是监听不到message应答数据。我让服务器的同事帮忙查询，发现我的连接刚创建完成就立即断开了，只经过了20ms，所以根本没有收到请求消息。但是客户端没有监听到连接断开，发送请求也是成功的。麻烦问下是什么问题呢？（我们服务器端用的是C++）

this.tcpSocket = socket.constructTCPSocketInstance();
      // 应答监听
      this.tcpSocket.on(SocketEventType.MESSAGE, value => {
        console.log("on message")
      });
      //连接监听
      this.tcpSocket.on(SocketEventType.CONNECT, () => {
        console.log("on connect")
      });
      //关闭监听
      this.tcpSocket.on(SocketEventType.CLOSE, () => {
        console.log("on close")
        this.isConnect = false
      });
      //错误监听
      this.tcpSocket.on(SocketEventType.ERROR,err =>{
        console.log("on error " + err)
      })
      //绑定
      this.tcpSocket.bind({ address: '0.0.0.0' }, err => {
        if (err) {
          console.log('bind fail ' + JSON.stringify(err));
          this.isBind = false;
          return;
        } else {
          console.log('bind success');
          this.isBind = true;
          //连接
          let promise = this.tcpSocket.connect({ address: {address: this.ip, port: this.port, family: 1} , timeout: 60000});
          promise.then(() => {
            console.log('connect success')
            this.isConnect = true
            //设置参数
            this.tcpSocket.setExtraOptions({
              keepAlive: true,
              receiveBufferSize: this.BUFFER_SIZE,
              OOBInline: true,
              TCPNoDelay: true,
              socketLinger: { on:true, linger:65535 },
              reuseAddress: true,
              socketTimeout: 60000,
            }).then(() => {
              console.log('setExtraOptions success');
              this.sendRequest('test message')
            }).catch(err => {
              console.log('setExtraOptions fail ' + JSON.stringify(err));
            });
          }).catch(err => {
            console.log('connect fail ' + JSON.stringify(err));
          });
        }
      })
