Question

在发展过程中,我非常能够看到寄来的包装。这在服务器的配对中是可能的。然而,在客户结束时,没有记录。我发现自己是ole。各地的标识。

Is it possible to override socket.emit and socket.on with console.log(arguments)? If I can override this at the before my socket, it would be really elegant.

有些人建议我推翻Parser。

你们在这方面的两点是什么?

EDIT

我尝试了Kato的建议,并写道:

var _origEmit = socket.emit;
socket.emit = function() { 
  console.log("SENT", Array.prototype.slice.call(arguments));
  _origEmit.call(socket, arguments);
};

This works. However, Not so much with socket.on. My strategy is to wrap each callback with a console.log. If you know python, it s kind of like putting function decorators on the callbacks that console.log the arguments.

(function(socket) { 
var _origOn = socket.on;
socket.on = function() { 
  var args = Array.prototype.slice.call(arguments)
    , handlerType = args[0]
    , originalCallback = args[1];

  var wrappedCallback = function() { 
    // replace original callback with a function 
    // wrapped around by console.log
    console.log("RECEIVED", Array.prototype.slice.call(arguments));
    originalCallback.call(socket, arguments);
  }

  _origOn.call(socket, [handlerType, wrappedCallback]);
}

任何人都能够指出,为什么key干的铺垫。是否可行?

至上socket.on, 您实际上需要超越socket.$emit/strong>。

举例来说,在客户和服务器方面(在书记本上测试):

(function() { var emit = socket.emit; socket.emit = function() { console.log( *** , emit , Array.prototype.slice.call(arguments)); emit.apply(socket, arguments); }; var $emit = socket.$emit; socket.$emit = function() { console.log( *** , on ,Array.prototype.slice.call(arguments)); $emit.apply(socket, arguments); }; })();

工作:

var _emit = socket.emit;
    _onevent = socket.onevent;

    socket.emit = function () { //Override outgoing
        //Do your logic here
        console.log( *** ,  emit , arguments);
        _emit.apply(socket, arguments);
    };

    socket.onevent = function (packet) { //Override incoming
        var args = packet.data || [];
        //Do your logic here
        console.log( *** ,  onevent , packet);
        _onevent.call(socket, packet);
    };

Answer 3

There is a module called socket.io-wildcard which allows using wildcards on client and server side, no need to overwrite anything anymore

var io         = require( socket.io )();
var middleware = require( socketio-wildcard )();

io.use(middleware);

io.on( connection , function(socket) {
  socket.on( * , function(){ /* … */ });
});

io.listen(8000);

<script src="/socket.io/socket.io.js"></script>
<script>
  (function() {

      var _origEmit = socket.emit;
      socket.emit = function() {
         console.log(arguments);
         _origEmit.apply(null, Array.prototype.slice.call(arguments));
      };


  })();
</script>
