UE4 FUdpSocketBuilder建立socket失败

简介

记录一个小坑，毕竟浪费了点时间。在开发过程中使用FUdpSocketBuilder建立了UDP通信基础，本来之前用的也很正常，已知没有想到会有什么问题，直到后来要接入新的硬件通信的时候，UDP死活建立不了socket，测试了IP和端口都是通的，这就很奇怪了，最后不知道哪里看到一点，原来FUdpSocketBuilder跨平台会有问题，所以还是使用普通的Socket吧。

使用

使用下面代码就能成功连接和接收消息

RemoteAddress = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateInternetAddr();
    bool bIsValid;
    RemoteAddress->SetIp(*SensorIP, bIsValid);
    RemoteAddress->SetPort(SensorPort);

    if (!bIsValid)
    {
        UE_LOG(LogSensorUDP, Error, TEXT("Sensor Ip is not valid!"));
        return false;
    }

    FIPv4Address UdpAddr;
    FIPv4Address::Parse(SensorIP, UdpAddr);
    FIPv4Endpoint Endpoint(UdpAddr, SensorPort/*5814*/);

	//SensorSocket = FUdpSocketBuilder(TEXT("SensorSendSocket")).BoundToEndpoint(Endpoint).WithReceiveBufferSize(MsgBufferSize).AsNonBlocking();
	SensorSocket = ISocketSubsystem::Get(PLATFORM_SOCKETSUBSYSTEM)->CreateSocket(EName(NAME_DGram), "SensorSendSocket");
	if (!SensorSocket)
	{
        UE_LOG(LogSensorUDP, Error, TEXT("Create Scoket failed!"));
        return false;
	}

	FTimespan Timespan = FTimespan::FromMilliseconds(100);//检查缓冲区间隔时间
	ReceiverSocket = new FUdpSocketReceiver(SensorSocket, Timespan, TEXT("SocketReceiver"));
	ReceiverSocket->OnDataReceived().BindRaw(this, &FSensorUDP::SocketRecveData);//绑定接收回调函数
	ReceiverSocket->Start();
