c++ - 不向 socket.io nodejs(服务器)发送数据 socket.io c++(客户端)

Question

对于我的项目，我想使用 Socket.io 从 App (c++) 到 WebServer (NodejS) 进行通信。

我们之间的连接有效，但是当我发出消息时，什么也没有发生 ...

客户端(C++)

int main(int argc, char const *argv[])
{
  sio::client h;
  h.connect("http://x.x.x.x:xxxx");
  string mess = "Bonjour !!!";
  h.socket()->emit("new message", mess); // Nothing is happening
  cout << "Message sended ..." << mess << endl;
  ...
}

服务器(NodeJs)

...
const io = require('socket.io')(server);

io.on('connection', (socket) => {
  console.log("New connexion..."); // It's Work

  socket.on('new message', function (data) { 
    console.log(data); // Never fire
  });
});


server.listen(xxxx, () => {
    console.log(`Server started on port xxxx`);
})

客户端输出

[2018-10-10 07:30:49] [connect] Successful connection
[2018-10-10 07:30:49] [connect] WebSocket Connection x.x.x.x:xxxx v-2 "WebSocket++/0.8.1" /socket.io/?EIO=4&transport=websocket&t=1539156649 101
Message sended ...Bonjour !!!
[2018-10-10 07:30:49] [warning] got non-close frame while closing
[2018-10-10 07:30:49] [warning] got non-close frame while closing
sio closed

服务器输出

Console show "New connexion..."

对于客户，我使用这个: https://github.com/socketio/socket.io-client-cpp

对于服务器:socket.io@2.1.1

有人有解决方案吗？

谢谢!

像这样发出:

string someString = "hi there";
message::list someStringMessage(someString);
io.socket()->emit("newString", someStringMessage);
