JSON-Data?

[TexxMedia]

Hi,

how i can change this great Class to send json-data?
$data = json_encode ( array ( 'var' => 'content' ) )

fwrite($fd, $this->hybi10Encode('42["' . $action . '", "' . addslashes($data) . '"]'));

Thank you

[psinetron]

you need to remove addslashes and send data as JSON

Спасибо друг за простой такой клиент
А как послать нормальный js объект так как его родной socket.io клиент посылает? чтоб Json не парсить :-)

Please give a sample, I always get a string on server side. How to correctly send JSON data ?

[psinetron]

You can send the JSON data as String. Just use json-encode/json_decode method.

I know this, but I need a JSON on server side because it's a bridge and I don't want to modify the server code.
The php client must be mimic the original socket.io client it's important.

My code :

<?php
 include_once("socket.io.php");

 $socketio = new SocketIO();

 $data = json_encode(array("commande" => "c"));

 if($socketio -> send("127.0.0.1", 83, "robotserveur", $data))
  echo "OK";
 else
  echo "NOK";

?>

My mod inside your class :

            //fwrite($fd, $this->hybi10Encode('42["' . $action . '", "' . addslashes($data) . '"]'));
            fwrite($fd, $this->hybi10Encode('42["' . $action . '", "' . $data . '"]'));

My server don't get the "robotserveur" (but I get a string type with your addslashes!)

[VigibotDev]

I must wireshark the content:(

[VigibotDev]

WebSocket content is not clear (gzip) ! I can't fgrep my string value inside a JSON.
I can get some ASCII from the server
Do you have an idea to debug this ?

No news to get a server side object and not a string ?

[VigibotDev]

Socket.io has "automatic JSON encoding/decoding" when I use .emit()
How to spoof the socket.io .emit() behavior ? How to force the server side (nodejs) to parce my JSON and return an object ?

[VigibotDev]

I found the problem !!! Don't double quote the JSON string ! and I finally get my server side object :)

socket.io sample frame :

42["eventName", {headers map}, data(primitive, array or object)]

42["createUser", {"requestId": "UUID"}, {
    "firstName": "John",
    "lastName": "Dow"
}]

42["deleteUser", {}, 10]

42["getUsers", {}, [1,2,3,4,5]]

Mod inside the class :

            //fwrite($fd, $this->hybi10Encode('42["' . $action . '", "' . addslashes($data) . '"]'));
            //fwrite($fd, $this->hybi10Encode('42["' . $action . '", "' . $data . '"]'));
            fwrite($fd, $this->hybi10Encode('42["' . $action . '", ' . $data . ']'));

My PHP socket.io client :

<?php
 include_once("socket.io.php");
 
 $socketio = new SocketIO();
 
 $data = json_encode(array("commande" => "c"));
 
 if($socketio -> send("127.0.0.1", 83, "robotserveur", $data))
  echo "OK";
 else
  echo "NOK";
?>

issue closed:)
