Reload Qlik Sense App via CMD command

Hi all,

Hope you're doing fine.

As clear in the title, I want to know if there is a way to reload a Qlik Sense App via command line? Maybe?

If there is, can you please share your knowledge with me?

I know that in qlikview, I can do as follow:

"C:\Program Files\QlikView\qv.exe" /R "C:\QlikviewApplications\app.qvw"

In Qlik Sense, I found this:

https://help.qlik.com/en-US/sense-developer/3.2/Subsystems/EngineAPI/Content/CreatingAppLoadingData/LoadData/reload-app.htm

The handle of the app is 1. The DoReload method is used.

The client sends:

{ "jsonrpc": "2.0", "id": 2, "method": "DoReload", "handle": 1, "params": [] }

The engine returns:

{ "jsonrpc": "2.0", "id": 2, "result": { "qReturn": true }, "change": [ 2 ] }

The app is reloaded.

With that,I can reload an app with the Engine API explorer of the dev-hub:

Now, is there anyone who could /want to guide me on how to make this an automated task?

Imagine I have 5 applications I want to reload them each day like this but without having to do the work manually?

How to proceed?

I'm using Qlik Sense Desktop as you can see.

I found this:

https://help.qlik.com/en-US/sense-developer/3.2/Subsystems/EngineAPI/Content/GettingStarted/connecting-to-engine-api.htm

Its says:

After you launch Qlik Sense Desktop and log in, you can connect to the Qlik Engine API using the following URI:

ws://localhost:4848/app/

For example, using JavaScript in a browser, make the following call:

var ws = new WebSocket("ws://localhost:4848/app");

I thus thought that to connect to the Engine API explorer; I had to copy this :

var ws = new WebSocket("ws://localhost:4848/app");

Then I used the 3 JSON scripts automatically generated and made sthing like this to execute with EasyPHP:

<?php

var ws = new WebSocket("ws://localhost:4848/app");

$a={

"handle": -1,

"method": "GetDocList",

"params": [],

"outKey": -1,

"id": 3

}

var_dump(json_decode($a));

$b={

"method": "OpenDoc",

"handle": -1,

"params": [

"C:\\Users\\BMC\\Documents\\Qlik\\Sense\\Apps\\reloadTest.qvf"

"outKey": -1,

"id": 2

}

var_dump(json_decode($b));

$c={

"jsonrpc": "2.0",

"id": 3,

"method": "DoReload",

"handle": 1,

"params": [],

"outKey": -1

}

var_dump(json_decode($c));

But, obviously, I got an error :

What am I do wrong? what should I change or redo?

Is there a solution to reload many applications dynamically ?

It's a really urgent need, hope you'll help !

Thanks,

In the tagged code you are treating JavaScript Code as PHP which will not work however using the following alongside your browser's developer tools to see the response will work.

```

var ws = new WebSocket("ws://localhost:4848/app");

var a={

"handle": -1,
"method": "GetDocList",
"params": [],
"outKey": -1,
"id": 3

}

console.log(a);

var b={

"method": "OpenDoc",
"handle": -1,
"params": [

"C:\\Users\\BMC\\Documents\\Qlik\\Sense\\Apps\\reloadTest.qvf"

"outKey": -1,
"id": 2

}

console.log(b);

var c={

"jsonrpc": "2.0",
"id": 3,
"method": "DoReload",
"handle": 1,
"params": [],
"outKey": -1
}

console.log(c);

</script>

```

You can then use JS Websocket functions to reload and perform all the other functions you want.

Hi,

I've got to the point where I can see the three objects created in the console in Chrome.

What is the next step required to actually call these objects?

Being a Qlik developer rather than a web developer it's not at all obvious.

Thanks in advance,

Steve

You can use QlikSenseReloader. Works both for Desktop and Enterprise versions.
