JavaScript -> onmessage can't able to get data

kartik.trade

var qs = getQueryStrings();
var tok1 = qs["request_token"];
var tok2="wss://websocket.kite.trade/?api_key=&user_id=&public_token=";
var tok3=tok2.concat(tok1);
//alert(tok3);
document.getElementById('message1').innerHTML=tok3;
var ws = new WebSocket(tok3);
//ws.binaryType = 'arraybuffer';

ws.onopen = function(ev)
{
document.getElementById('message').innerHTML="Connected to server";
document.getElementById('message1').innerHTML="State" +ws.readyState;
var message = '{"a": "subscribe", "v": [884737]}';
ws.send(JSON.parse(message));
message = '{"a": "mode", "v": ["ltp", [884737]]}';
ws.send(JSON.parse(message));
};
ws.onclose = function(ev)
{
document.getElementById('message').innerHTML="Disconnected";
};
ws.onmessage = function(ev)
{
document.getElementById('message').innerHTML="Receiving...";
var blob=ev.data
document.getElementById('message2').innerHTML=blob.size;
};

Why don't you check the network inspector to see what's happening to the request?

PS: You are passing the api_key and user_id, yes?

kartik.trade

Ya I already pass api_key, User_id and public token(access_token).
But can't able to get data.

kartik.trade

I also check with network inspector but request of websocket.kite.trade.... return me blank cache.

@kartik.trade What is the response code from websocket.kite.trade? It should `101 Switching protocols`. You will not get a response body.

Also, I just noticed that you're doing a JSON.parse() and sending the resultant objects to the API. That is incorrect. You should send the actual JSON string to the API. So `ws.send(message)`

kartik.trade

Ok. I got Data. I pass parse string instead of Json String.

Do you not think that you should include websocket streaming and postback in "Kite Connect PHP library"?

We have it in the Python library. PHP doesn't make a good fit for long running client/server applications, which is why we haven't looked into it.
