Connecting to localhost gives websocket error

bekahbeets — Thu, 01 Dec 2016 17:59:28 GMT

I am getting started with qlik desktop and I have connected to the desktop via Visual Studio plugin. I have added 2 sheets to visual studio, but when i debug to localhost, I get errors

In .js file...

var config = {

host: window.location.hostname,

prefix: '/',

port: window.location.port,

isSecure: window.location.protocol === "https:"

};

require.config( {

baseUrl: (config.isSecure ? "https://" : "http://") + config.host + (config.port ? ":" + config.port : "") + config.prefix + "resources"

});

require(["js/qlik"], function(qlik) {

// open the app

var app = qlik.openApp('c31e2aba-3b46-4b13-8b87-c5c2514dea1d', config); //someone please tell me what this id is and where it comes from because I c&p'd off of the tutorials and idk what goes here

});

In VS:

<asp:Content ID="Content2" ContentPlaceHolderID="cphMain" runat="server">

</asp:Content>

and the errors 1 and 2:

Websocket connection to 'ws://localhost......aspx' failed. Error during Websocket handshake. Unexpected response code: 404

Uncaught Error: Mismatched anonymous define() module ...from require.js:6

So the first thing to do is forget what qlik tells you to do to connect to it. I used the javascript built in websocket commands to connect and it works fine for connection.

Tutorials: http://blog.teamtreehouse.com/an-introduction-to-websockets, websocket.org Echo Test - Powered by Kaazing

var socket = {};

window.onload = function () {

// Get references to elements on the page. these are div fields and buttons in the html.

var form = document.getElementById('message-form');

var messageField = document.getElementById('message');

var messagesList = document.getElementById('messages');

var socketStatus = document.getElementById('status');

var closeBtn = document.getElementById('close');

// The rest of the code in this tutorial will go here...

var websocketURL = 'see_attached_pic_to_find_out_what_this_is';

var socketOnClose = function (msg) {

console.log('websocket disconnected - waiting for connection');

websocketWait();

};

var socketOnMessage = function (msg) {

console.log("RECEIVED ");

//console.log(msg.data);

};

var socketOnOpen = function (msg) {

console.log("websocket opened");

qlikJSONtoServer();

};

function websocketWait() {

setTimeout(function () {

socket = new WebSocket(websocketURL);

socket.onopen = socketOnOpen;

socket.onclose = socketOnClose;

socket.onmessage = socketOnMessage;

}, 1000);

};

websocketWait();

function qlikJSONtoServer() {

// DocLIST/AppList

console.log("GET DOC/App LIST");

//from connect to engine command in qs engine-api-explorer

socket.send(JSON.stringify(

{ "handle": -1, "method": "GetDocList", "params": [], "outKey": -1, "id": 1 }

));

//continues with more commands from the engine api explorer...

}

I really did not get this

var websocketURL = 'see_attached_pic_to_find_out_what_this_is';

Will the target id not change dynamically, on each request?? should I hardcode that url here??

How do I get the ticket Id from?

theres a pic attached to the comment.

I haven't got that far to get it from code, but when you execute a macro, the ticket id will be at the end of the url

Thanks for this, I was able to connect and retrieve the list of apps. I found that I didn't need to supply the TicketID. I assume this was done by behind the scenes.
