将Socket.io流连接到节点repl流

Question

我用socket.io创建了一个快速应用程序.现在我想要一个浏览器终端与我在节点中创建的repl连接.这就是我想出的

var io = io.listen(server);
var sessionSockets = new SessionSockets(io, sessionStore, cookieParser);

sessionSockets.on('connection', function (err, socket, session) {
  var stream = createStream(socket);
  var replInstance = repl.start({
    prompt: "> ",
    input: stream,
    output: stream
  });
  repls[socket.id] = replInstance;
});

var createStream = function(socket) {
  var stream = new Stream();
  stream.readable = true;
  stream.resume = function() {};

  stream.write = function(data) {
    socket.emit('stdout', data);
  };

  socket.on('stdin', function(data) {
    // emit data to repl stream - DOES NOT WORK
    stream.emit('data', data);
  });

  return stream;
};

它的作用是将控制台输出推送到socket.io连接并在前端显示它们.它不是从repl的前端输入数据.

想法？

我刚刚尝试了您的代码，我认为您可能需要在流发出时换行以便 repl 识别它：

// emit data to repl stream - DOES NOT WORK
stream.emit('data', data+'\n');
