RTCPeerConnection.generateCertificate() is returning an empty object - webrtc

Here is the code (browser Chrome on Ubuntu):
RTCPeerConnection.generateCertificate(
{ name: "RSASSA-PKCS1-v1_5",
modulusLength: 2048,
publicExponent: new Uint8Array([1, 0, 1]),
hash: "SHA-256" })
.then
( function(cert) {
console.log("typeof: " + typeof(cert));
console.log("S: " + JSON.stringify(cert));
},
function(err) {
console.log("E: " + err);
}
);
It displays:
typeof: object
S: {}
Actually this is almost the exact code from Mozilla site
Also, conforms to the WebRTC specs Section 4.9

The certificate isn't serializable. If you add a console.log(cert); you'll see something along the lines of RTCCertificate { expires: 1595444355114 }. That is intentional, you can not export the key like you can in webcrypto. And there is no toJSON

Yes,
cert.getFingerprints()[0].value.toUpperCase().trim();
https://pi.pe/p/genCertTest.html
is a page that exercises generateCertificate()

API call from google sheets is too long

I am trying to write a script in google sheets to update my 3commas bots. The API requires a number of mandatory fields are passed even when there's only 1 item that needs to be updated.
The code I have is below and it uses the values already read from the platform updating only the base_order_volume value. This works perfectly except for when the pairs value is long (more the 2k chars) and then I get an error from the UrlFetchApp call because the URL is too long.
var sheet = SpreadsheetApp.getActiveSheet();
var key = sheet.getRange('F4').getValue();
var secret = sheet.getRange('F5').getValue();
var baseUrl = "https://3commas.io";
var editBots = "/ver1/bots/"+bots[botCounter].id+"/update";
var patchEndPoint = "/public/api"+editBots+"?";
.
.
[loop around values in sheet]
.
.
var BaseOrder=Number(sheet.getRange(rowCounter,12).getValue().toFixed(2));
var botParams = {
"name": bots[botCounter].name,
"pairs": bots[botCounter].pairs,
"max_active_deals": bots[botCounter].max_active_deals,
"base_order_volume": BaseOrder,
"take_profit": Number(bots[botCounter].take_profit),
"safety_order_volume": bots[botCounter].safety_order_volume,
"martingale_volume_coefficient": bots[botCounter].martingale_volume_coefficient,
"martingale_step_coefficient": Number(bots[botCounter].martingale_step_coefficient),
"max_safety_orders": bots[botCounter].max_safety_orders,
"active_safety_orders_count": Number(bots[botCounter].active_safety_orders_count),
"safety_order_step_percentage": Number(bots[botCounter].safety_order_step_percentage),
"take_profit_type": bots[botCounter].take_profit_type,
"strategy_list": bots[botCounter].strategy_list,
"bot_id": bots[botCounter].id
};
var keys = Object.keys(botParams);
var totalParams = keys.reduce(function(q, e, i) {
q += e + "=" + encodeURIComponent(JSON.stringify(botParams[e])) + (i != keys.length - 1 ? "&" : "");
return q;
},endPoint);
var signature = Utilities.computeHmacSha256Signature(totalParams, secret);
signature = signature.map(function(e) {return ("0" + (e < 0 ? e + 256 : e).toString(16)).slice(-2)}).join("");
var headers = {
'APIKEY': key,
'Signature': signature,
};
try {
var params = {
'method': 'PATCH',
'headers': headers,
'muteHttpExceptions': true
};
var response = JSON.parse(UrlFetchApp.fetch(baseUrl + totalParams, params).getContentText());
I have tried to set the botParams as a payload in the params but when I do the signature is incorrect.
I anyone knows how to use sheets to make a call using extensive length of parameters I'd appreciate any help at all
Some sample data for the bots array would be
{
"name": "TestBot",
"base_order_volume": 0.001,
"take_profit": 1.5,
"safety_order_volume": 0.001,
"martingale_volume_coefficient": 2,
"martingale_step_coefficient": 1,
"max_safety_orders": 1,
"active_safety_orders_count": 1,
"safety_order_step_percentage": 2.5,
"take_profit_type": "total",
"stop_loss_percentage": 0,
"cooldown": 0,
"pairs": ["BTC_ADA","BTC_TRX"],
"trailing_enabled":"true",
"trailing_deviation":0.5,
"strategy_list": [{"strategy":"cqs_telegram"}]
}
Thanks in advance
I'd consider using a Cloud Function to either do the heavy lifting, or, if you're worried about costs, use it as a proxy. You can then call the cloud function from Google Sheets. Cloud Functions can be written in whatever language you're most comfortable with, including Node.
Check the GCP pricing calculator to see what the cost would be. For many cases it would be completely free.
This should give you a sense of how to use cloud functions for CSV creation:
https://codelabs.developers.google.com/codelabs/cloud-function2sheet#0
Here is a SO question with an answer that explains how to query cloud functions with authentication.

Vue.js Nuxt - cannot access Array (value evaluated upon first expanding error)

I have the following function which gives me an array called URLs
const storageRef = this.$fire.storage.ref().child(fileName)
try {
const snapshot = storageRef.put(element).then((snapshot) => {
snapshot.ref.getDownloadURL().then((url) => {
urls.push(url)
})
})
console.log('File uploaded.')
} catch (e) {
console.log(e.message)
}
});
console.log(urls)
console.log("about to run enter time with imageurls length " + urls.length)
When I run console.log(URLs) initially I do see the array like the following
[]
0: "testvalue"
length: 1
__proto__: Array(0)
However, there is a small information icon stating
This value was evaluated upon first expanding. The value may have changed since.
Because of this, when I try to get the length of URLs, I get zero, meaning the value is being updated.
Does anyone know what's happening? I am using Vue.JS/Nuxt.

issue with c8ydevicecontrol.create

the code:
this.sendOperations = function () {
var operation = {
deviceId: '12161',
com_cumulocity_model_WebCamDevice: {

parameters: {
duration: '5s',
quality: 'HD'
}
}
};
c8yDeviceControl.create(operation);
Result:
a new operation will be created in cumulocity server, but in the meantime, the chrome brower on which the app is runing will report some errors, although it looks like the app is still runing after that:
angular.js:9997 TypeError: Cannot read property 'match' of null

any suggestion? Thanks

Can Gulp change LESS variables?

I'm looking to toggle IE8 mode in my LESS files and automated the file generation in Gulp.
This is where I stopped in what to pass gulp-less (minus a bunch of stuff):
var IE = true;
var LESSConfig = {
plugins: [ ... ],
paths: LESSpath,
ie8compat: IE, //may as well toggle this
// Set in variables.less, #ie:false; - used in mixin & CSS guards
// many variations tried
// globalVars: [ { "ie":IE } ],
modifyVars:{ "ie":IE }
};
...
.pipe( less ( LESSConfig ) )
Is variable modification not supported in Gulp?
I'd like to avoid using gulp-modify et al if I can. I'd like to keep the build system fairly abstracted from the source files.
modifyVars is working for me now:
...
var LESSConfig = {
paths: paths.LESSImportPaths,
plugins: [
LESSGroupMediaQueries,
LESSautoprefix
],
modifyVars: {
ie: 'false'
}
};
var LESSConfigIE = {
paths: paths.LESSImportPaths,
modifyVars: {
ie: 'true'
}
};
function processLESS (src, IE, dest){
return gulp.src(src)
.pipe( $.if( IE, $.less( LESSConfigIE ), $.less( LESSConfig ) ) )
.pipe( $.if( IE, $.rename(function(path) { path.basename += "-ie"; }) ) )
.pipe( gulp.dest(dest) )
}
// build base.css files
gulp.task('base', function() {
return processLESS( paths.Base + '/*.less', false, paths.dest );
});
// build base-ie.css files for IE
gulp.task('baseIE', function() {
return processLESS( paths.Base + '/*.less', true, paths.dest );
});
Since I could not get this to work with gulp-lessand it became apparent to me that the application of globalVars and modifyVars are both broken, I came up with a different solution.
You can use gulp-append-prepend to write your variables into the file before gulp-less processes it. A little less elegant but, on the plus side, it actually works.
Something like this:
gulp.src('main.less')
.pipe(gap.prependText('#some-global-var: "foo";'))
.pipe(gap.appendText('#some-modify-var: "bar";'))
.pipe(less())
.pipe(gulp.dest('./dest/'));
Nowadays (2019) this problem seems to be fixed.
However it cost me still a lot of time to get it running.
Here is what I did:
gulp.task('lessVariants', ['less'], function() {
return gulp.src('less/styles.less', {base:'less/'})
.pipe(less({modifyVars:{'#color1': '#535859'}))
.pipe(less({modifyVars:{'#color2': '#ff0000'}))
.pipe(less({modifyVars:{'#color3': '#ccffcc'}))
.pipe(rename('styles.modified.css'))
.pipe(cleanCSS())
.pipe(gulp.dest(distFolder + 'css'))
})
This did not work. Only the last variable was modified. I changed it as follows to get it working:
gulp.task('lessVariants', ['less'], function() {
return gulp.src('less/styles.less', {base:'less/'})
.pipe(less({modifyVars: {
'#color1': '#535859',
'#color2': '#ff0000',
'#color3': '#ccffcc',
}}))
.pipe(rename('styles.variant.css'))
.pipe(cleanCSS())
.pipe(gulp.dest(distFolder + 'css'))
})

Strophe.attach not working - I am using openfire locally

I am trying to implment the XMPP Client. I am using BOSH Connection manager and can run the Strophe.connect but not Strophe.Attach. I have tried incrementing the RID, but no effect.. Any help please ? There is no error here, but the Strophe.Status.CONNECTED is never reached via the attach method and so I cannot send IQ or Presence.
Here is my code
try
{
var cookieJid = $.cookie("jid");
var cookieSid = $.cookie("sid");
var cookieRid = $.cookie("rid");
var connt = new Strophe.Connection("http://localhost:7070/http-bind/");
connt.attach(cookieJid, cookieSid, cookieRid + 1, function(status)
{
if (status === Strophe.Status.CONNECTED)
{
alert ("hola connected");
$("#userName").append("hola connected : " + connt.jid );
var iq = $iq({type: 'get'}).c('query', {xmlns: 'jabber:iq:roster'});
connt.sendIQ(iq, handleRoster);
connt.send($pres());
}
});
}
catch (e)
{
$("#userName").append("Pinky error is " + e);
}
Edit
Thanks Eric and Charlie.
So I took the latest Strophe.js and now Attached status does work.
But the connection disconnects instantaneously. I am not even able to fetch the Roster.
We can possibly do every thing with Connection.attach() as we would with connection.connect(), right?
Any thoughts?
Change the line:
if (status === Strophe.Status.CONNECTED)
...to...
if (status === Strophe.Status.CONNECTED || status === Strophe.Status.ATTACHED)
Are you using the latest Strophe library? In the version I'm using, I see that the status can be these values:
Status: {
ERROR: 0,
CONNECTING: 1,
CONNFAIL: 2,
AUTHENTICATING: 3,
AUTHFAIL: 4,
CONNECTED: 5,
DISCONNECTED: 6,
DISCONNECTING: 7,
ATTACHED: 8
}
Make sure you convert your cookieRid to a Number by using new Number(cookieRid). Otherwise, when you do +1 on it, you will get "####1".
You can test this out for yourself in Javascript:
var s = "123";
alert(s+1); // "1231" and not "124"
Also, as Eric answered, there is a status ATTACHED so you need to handle that event.
