No response from OpenDoc method on desktop

mgranillo — Tue, 13 Sep 2016 15:49:19 GMT

Can someone tell me what's wrong with my code?

I'm trying to communicate with the desktop engine using the opendoc method and the browser.

The getdoclist method works so i have a working connection. I just don't know why i dont get a result for the OpenDoc method.

<!doctype html>

<html>

<head>

function connect() {

qsocks.Connect().then(global => {

global.getDocList().then(function(documents) {

var available_docs = [];

documents.forEach(function(document_entry){

available_docs.push(document_entry.qDocId);

});

console.log(available_docs);

});

global.OpenDoc("H:\My Documents\Qlik\Sense\Apps\Consumer_Sales.qvf").then(function(app) {

app.GetAllInfos().then(function(appInfos){

var measures_list = [];

appInfos.qInfos.forEach(function(document_infos){

if(document_infos.qType=='measures'){

measures_list.push(document_infos.qId)

}

});

console.log(measures_list.length());

});

}

connect();

</script>

</script>

</head>

<body>

</body></html>

That looks fine but I'm guessing that the path is a mapped drive so maybe something gets messed up with UNC there.
Have you tried inputting the full path and/or placing the file locally and try it that way?

If you get stuck then feel free to join us on slack and ping me and we can take a look at it,

Alexander,

Thanks for the advice. That path is a mapped drive but there's nothing I can do to change that. It's our IT infrastructure here. I've tried re-pointing the apps directory in the settings.ini file but this stopped working in Sense 3.0.

I've joined the slack channel. What do you use this for?

Hi,

You should not need to give the full path if the app is in the default Apps directory, so you could try just 'Consumer_Sales.qvf'.

If you do need the full path you might try with double backslash ("H:\\My Documents\\Qlik\\Sense\\Apps\\Consumer_Sales.qvf".

BTW, is the Consumer_Sales app in the console output? What does it say?

Hope this helps

Erik

I tried with double backslash and just the app name but neither worked.

Consumer Sales is in the output and returns the whole path: "H:\My Documents\Qlik\Sense\Apps\Consumer_Sales.qvf"

Try putting the app the on C:\ drive as just do openDoc('C:\\app.qvf')

I tried your suggestion but it didn't work. I tried single slashes in the path and using just the app name but never received output in the console.

In case this helps, here's the Engine API Explorer output:

Hi Michael,

Try encoding the pathname, either by hand(you can see what it should look like in Engine API explorer) or with encodeURIComponent.

Let us know if this helps

Hi Mike,

I've payed around with this abit in node and can't really reproduce your problem. I suggest you make sure you catch your errors in all qSocks calls and see if you find something. BTW it is getAllInfos with a lowercase g, looks like qsocks is not quite consistent with upper/lowercase (Connect etc..).

Another point to remember is that you can only open one app on a socket. To handle this I use qsocks.ConnectOpenApp (yes, it should be uppercase C), which will create one web socket for each app. This is also the way Engine API explorer works, and the way you are supposed to do it on server, since Qlik Sense load balancing needs the app id to be URL.

My code looks like this:

const qsocks = require('../../qsocks');
const extend = require('util')._extend;
const Promise = require('promise');


const config = {
    host: 'localhost',
    port: 4848,
    isSecure: false
};


function getAppObjects(appname) {
    var cfg = extend({}, config);
    cfg.appname = appname;
    //open app on a new socket
    return qsocks.ConnectOpenApp(cfg).then(function(result) {
        //result[0] will be global, result[1] will be the app
        var app = result[1];
        return app.getAllInfos().then(function(appInfos) {
            var objs = {};
            appInfos.qInfos.forEach(function(info) {
                if (!objs[info.qType]) {
                    objs[info.qType] = [];
                }
                objs[info.qType].push(info.qId);
            });
            console.log("\nApp:\t", cfg.appname);
            for (p in objs) {
                console.log(p, ":\t", objs
.join());
            }
        }).catch(function(err) {
            console.log("GetAllInfos failed", err);
        });
    }).catch(function(err) {
        console.log("openDoc failed", err);
    });


}
//Connect to QIX engine
qsocks.Connect(config).then(function(global) {
    //fetch the app list
    global.getDocList().then(function(docList) {
        var promises = [];
        docList.forEach(function(doc) {
            promises.push(getAppObjects(doc.qDocId));
        });
        //promises.push(getAppObjects("D:\\Ekonomi.qvf"));
        Promise.all(promises).then(function() {
            process.exit(0);
        });
    });
}).catch(function(err) {
    console.log("err", err);
    process.exit(1);
});

It also available on github qsocks/list-local-apps.js at master · erikwett/qsocks · GitHub

When I try this with an app that is not in MyDocuments\Qlik\Sense\Apps its not included in the app list, but you can open a socket to it anyhow.

Hope this helps

Erik

The two Connect methods should be the only ones with a capitalized method name as it returns a new instance/connection to the Engine.

All API methods are properly lowercased while "classes" are capitalized.

Has this problem been resolved? I cannot open a local app with openDoc().

qsocks has been deprecated for quite a while now. I would recommend you check out https://github.com/qlik-oss/enigma.js which is a much better alternative.
