将参数传递给另一个文件 JS 中的函数

Question

In my app.js I have

io.sockets.on("connection", connectSocket);

and then in a different file I have:

const connectSocket = (socket, bitlyAppURL) => {
  socket.once(AUTHENTICATED_CONNECTION_REQUEST, params => {
    connectAuthenticatedSocket(socket, params, bitlyAppURL);
  });

  socket.once("disconnect", disconnectSocket);

  socket.emit(AUTHENTICATE_YOURSELF);
};

but I'm not sure how to pass this bitlyAppURL into the function in app.js .

使用socket.on的回调：

io.sockets.on("connection", socket => connectSocket(socket, bitlyAppURL));
