Question

我们有一个学生项目，我的队友必须通过套接字连接到我。我运行一个HTML5网页，并与我创建一个Socket.IO服务器分开。他正在运行一个C ++程序，在那里他扫描RFID，他必须通过套接字发送到我的网页。我们正努力与他建立联系。有没有办法让他用C ++连接我的websocket？

我在没有包含的情况下复制他的所有代码（因为我没有c ++程序员）

int main(array<System::String ^> ^args)

        array<unsigned char>^ MSG = gcnew array<unsigned char>(1024);
        int a;
        String ^dataAux;// ^dataSend;

        SerialPort^ arduino;
        arduino = gcnew SerialPort("COM4", 2400);
        arduino->ReadTimeout = 1000;

        for(int b=0;b<50;b++)
                dataArray[b]="1234569877";

        while(1)
        {    
                a=0;
                try{
/*  //LEITURA COM TIMEOUT
                arduino->Open();
                dataAux="";
                arduino->DiscardOutBuffer();
                dataAux = arduino->ReadLine();
                arduino->Close();

如果要在C ++中使用WebSockets，则应考虑使用C ++ WebSocket库。这个维基百科上有一个列表page。

我之前使用libwebsockets将HTML 5应用程序连接到C ++应用程序。该库附带了示例客户端和服务器代码here。

你能从C ++程序连接到Socket.IO吗？
