I'm trying to verify a document from QLDB using nodejs. I have been following the Java verification example as much as I can, but I'm unable to calculate the same digest as stored on the ledger.
This is the code I have come up with. I query the proof and block hash from QLDB and then try to calculate digest in the same way as in Java example. But after concatinating the two hashes and calculating the new hash from the result I get the wrong output from crypto.createHash('sha256').update(c).digest("base64"). I have also tried using "base64" instead of "hex" with different, but also wrong result.
const rBlock = makeReader(res.Revision.IonText);
var block = [];
rBlock.next();
rBlock.stepIn();
rBlock.next();
while (rBlock.next() != null) {
if (rBlock.fieldName() == 'hash') {
block.push(Buffer.from(rBlock.byteValue()).toString('hex'));
}
}
console.log(block);
var proof = [];
const rProof = makeReader(res.Proof.IonText);
rProof.next();
rProof.stepIn();
while (rProof.next() != null) {
proof.push(Buffer.from(rProof.byteValue()).toString('hex'));
}
var ph = block[0];
var c;
for (var i = 0; i < proof.length; i++) {
console.log(proof[i])
for (var j = 0; j < ph.length; j++) {
if (parseInt(ph[j]) > parseInt(proof[i][j])){
c = ph + proof[i];
break;
}
if (parseInt(ph[j]) < parseInt(proof[i][j])){
c = proof[i] + ph;
break;
}
}
ph = crypto.createHash('sha256').update(c).digest("hex");
console.log(ph);
console.log();
}
I have figure it out. The problem was that I was converting the blobs to hex strings and hash them instead of the raw values. For anyone wanting to verify data in node, here is the bare solution:
ledgerInfo.getRevision(params).then(res => {
console.log(res);
const rBlock = makeReader(res.Revision.IonText);
var ph;
rBlock.next();
rBlock.stepIn();
rBlock.next();
while (rBlock.next() != null) {
if (rBlock.fieldName() == 'hash') {
ph = rBlock.byteValue()
}
}
var proof = [];
const rProof = makeReader(res.Proof.IonText);
rProof.next();
rProof.stepIn();
while (rProof.next() != null) {
proof.push(rProof.byteValue());
}
for (var i = 0; i < proof.length; i++) {
var c;
if (hashComparator(ph, proof[i]) < 0) {
c = concatTypedArrays(ph, proof[i]);
}
else {
c = concatTypedArrays(proof[i], ph);
}
var buff = crypto.createHash('sha256').update(c).digest("hex");
ph = Uint8Array.from(Buffer.from(buff, 'hex'));
}
console.log(Buffer.from(ph).toString('base64'));
}).catch(err => {
console.log(err, err.stack)
});
function concatTypedArrays(a, b) {
var c = new (a.constructor)(a.length + b.length);
c.set(a, 0);
c.set(b, a.length);
return c;
}
function hashComparator(h1, h2) {
for (var i = h1.length - 1; i >= 0; i--) {
var diff = (h1[i]<<24>>24) - (h2[i]<<24>>24);
if (diff != 0)
return diff;
}
return 0;
}
I'm facing a problem with my code... I make a query to my DB to check if a mac address of a array of macs is on the DB. If I have any result I return the count of macs in my DB and if is > 0 then I don't add nothing cause the mac already is listed, but if my result.count = 0 then I will add a new record.
My new record just have the mac address. For this I'm trying:
var countRepetidos = 0
var countPromises = []
if (obj.data.list != {} && obj.data.list.length > 0) {
var aux = obj.data["list"]
countRepetidos = 0
for (var i = 0; i < aux.length; i++) {
countPromises.push(Database.Probing.getMacAdress(aux[i]).then(function(data) {
console.log("probing countPromises aux[i] ", aux[i])
if (data.count > 0) {
countRepetidos += 1
} else {
Database.Probing.addMac(aux[i])
}
return Promise.resolve()
}))
}
Promise.all(countPromises).then(() => {
dataRepeated = [obj.data.stats.since, countRepetidos]
listaRepeated.push(dataRepeated)
console.log("probing listaRepeated --> ", listaRepeated)
if (listaRepeated != [] && (listaRepeated[0][0] != undefined && listaRepeated[0][1] != undefined)) {
Database.Probing.getLastTimestamp("probing_repeated", device.id).then(function(data) {
var lastTimestamp = data.date_part
console.log('probing lastTimestamp ', lastTimestamp * 1000)
if (lastTimestamp != listaRepeated[0][0] / 1000) {
Controllers.Agregate.agregateData("probing_repeated", 5 * 60, listaRepeated, dbHistConnectionString, device.id, device.network_id, device.organization_id, ["time", "clients"])
}
})
}
})
}
The problem is after the then of Database.Probing.getMacAddress my aux[i] gets undefined and I need this value to insert into my DB.
Anyone can help?
You need to preserve the value of i. You can do this way:
for (var i = 0; i < aux.length; i++) {
(function(i) {
countPromises.push(
Database.Probing.getMacAdress(aux[i]).then(function(data) {
console.log("probing countPromises aux[i] ", aux[i])
if (data.count > 0) {
countRepetidos += 1
} else {
Database.Probing.addMac(aux[i])
}
return Promise.resolve()
}))
})(i)
}
Edit 1: As suggested by #lain, use let over var
for (let i = 0; i < aux.length; i++) {}
I am on a frame in Animate by Adobe. When I add a "change" listener to my tween I lose scope when I hit the change function called animateParticle. Also related, the tween attached to the particle doesn't recognize .setPaused(true) function.
this.stop();
that = this;
var particleCount = 0;
var aParticle;
var mySpeed = 12;
var myRotation = 4;
var totalParticles = 5;
var stopParticles = false;
var particleHolder = new createjs.Container();
var mc_coll1 = this.parent.mc_coll0;
mc_coll1.setBounds(0,0,156,34);
var collission_ar = [this.parent.mc_coll0, this.parent.mc_coll1, this.parent.mc_coll2, this.parent.mc_coll3, this.parent.mc_coll4, this.parent.mc_coll5, this.parent.mc_coll6, this.parent.mc_coll7, this.parent.mc_coll8, this.parent.mc_coll9, this.parent.mc_coll10, this.parent.mc_coll11, this.parent.mc_coll12, this.parent.mc_coll13, this.parent.mc_coll14];
var totalCollisions = collission_ar.length;
this.addChild(particleHolder);
var xRange = width;
var yRange = height;
var scaleNum = 1;
//var collisionMethod = ndgmr.checkPixelCollision;
this.scaleX = 1;
this.scaleY = 1;
createParticles()
setTimeout(function(){
removeTimer();
//clearTimeout(that.pauseVar);
}, 2000)
function createParticles(){
var particle_ar = [];
var randNum = Math.ceil(Math.random() * totalParticles);
aParticle = new lib['MC_leaf'+randNum]();
aParticle.name = 'aParticle'+particleCount;
aParticle.x = Math.random() * xRange;
aParticle.y = -Math.random() * 15;
theNum = Math.random() * scaleNum;
aParticle.scaleX = theNum
aParticle.scaleY = theNum
aParticle.alpha = 1;
aParticle.collision = Math.floor(Math.random() * 2);
particleHolder.addChild(aParticle);
particleCount++;
var tween2 = createjs.Tween.get(aParticle).wait(0).to({y:yRange}, 2000, createjs.Ease.easeOut).call(removeObj,[aParticle], that).addEventListener('change', animateParticle.bind(that));
aParticle.tween = tween2;
if(!stopParticles){
timer = setTimeout(function() { createParticles() }, 100);
}
}
function animateParticle (event){
var part = event.currentTarget;
var mc_newColl;
console.log('part '+part.name);
for(var i=0; i < totalCollisions; i++){
// collision checking
mc_newColl = collission_ar[i];
var intersection = checkIntersection(part,mc_newColl);
if (intersection){
part.tween.setPaused(true);
//part.removeEventListener("tick", animateParticle.bind(that));
}
}
}
function checkIntersection(part, coll) {
if ( part.x >= coll.x + coll.width || part.x + part.width <= coll.x || part.y >= coll.y + coll.height || part.y + part.height <= coll.y ) return false;
return true;
}
function removeObj(part){
particleHolder.removeChild(part);
}
function removeTimer() {
stopParticles = true;
timer = clearInterval();
//var tween2 = createjs.Tween.get(particleHolder).wait(0).to({alpha:0}, 2000, createjs.Ease.easeOut);
}
//var timer = setInterval(function() { createParticles() }, 200, that);
var timer = setTimeout(function() { createParticles() }, 100, this);
In animateParticle, part is undefined.
The target of the change event will not be the particle, but the tween itself, since it is the dispatching object.
createjs.Tween.get(particle).to({x:1000}, 2000)
.on("change", function(event) {
console.log(event.target); // Tween
console.log(event.target.name); // undefined
console.log(event.target.target); // particle
console.log(event.target.target.name); // particle's name
}, that);
The undefined you are seeing is not the particle, but the name that you are logging.
Note that using on instead of addEventListener lets you pass a scope as a parameter instead of using bind.
Hope that helps.
I need to read the "Top Nav", the "Children Nodes" and check if each node is visible.
I am using JSOM to accomplish this. Everything is working fine except for the get_isVisible() function. It always returns true. MSDN: http://msdn.microsoft.com/en-us/library/office/jj246297.aspx
I am on a publishing site in 2013 and I know some of the items are hidden. (My web and context are defined outside of this snippet)
var visParents = [], visChildren = [];
var topNodes = web.get_navigation().get_topNavigationBar();
context.load(topNodes);
context.executeQueryAsync(onQuerySucceeded, onQueryFailed)
function onQuerySucceeded() {
var nodeInfo = '';
var nodeEnumerator = topNodes.getEnumerator();
while (nodeEnumerator.moveNext()) {
var node = nodeEnumerator.get_current();
nodeInfo += node.get_title() + '\n';
if (node.get_isVisible())
visParents.push(node);
}
console.log("Current nodes: \n\n" + nodeInfo);
console.log("Visible Parents", visParents)
}
function onQueryFailed(sender, args) {
alert('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
}
It is a known issue, it seems that SP.NavigationNode.isVisible property does not correspond to the property that indicates whether navigation node is hidden or shown.
Please refer "Hidden" property of SPNavigationNode for a details
The following function demonstrates how to retrieve hidden node Urls:
function getGlobalNavigationExcludedUrls(Success,Error)
{
var context = new SP.ClientContext.get_current();
var web = context.get_web();
var subwebs = web.get_webs();
var pagesList = web.get_lists().getByTitle("Pages");
var pageItems = pagesList.getItems(SP.CamlQuery.createAllItemsQuery());
var allProperties = web.get_allProperties();
context.load(web);
context.load(subwebs);
context.load(allProperties);
context.load(pageItems);
context.executeQueryAsync(
function() {
var excludedIds = allProperties.get_item('__GlobalNavigationExcludes').split(';');
var exludedUrls = [];
for (var i = 0; i < excludedIds.length - 1; i++ )
{
for (var j = 0; j < subwebs.get_count(); j++ )
{
var subweb = subwebs.getItemAtIndex(j);
if(subweb.get_id().toString() == excludedIds[i]){
exludedUrls.push(subweb.get_serverRelativeUrl());
break;
}
}
for (var j = 0; j < pageItems.get_count(); j++ )
{
var pageItem = pageItems.getItemAtIndex(j);
if(pageItem.get_item('UniqueId').toString() == excludedIds[i]){
exludedUrls.push(web.get_serverRelativeUrl() + pageItem.get_item('FileRef'));
break;
}
}
}
Success(exludedUrls);
},
Error
);
}
//Usage: print excluded nodes Urls
getGlobalNavigationExcludedUrls(function(excludedNodeUrls){
for (var j = 0; j < excludedNodeUrls.length; j++ )
{
console.log(excludedNodeUrls[j]);
}
},
function(sender,args){
console.log(args.get_message());
});
I'm trying to create a simple chrome extension using the following google RSS reader sample,
http://code.google.com/chrome/extensions/samples.html#597015d3bcce3da693b02314afd607bec4f55291
I can add links in the pop-up window that open tabs, but not from the feeds themselves.
Looping through the items in the feed, grabbing title tags and link tags, I want the title to link the the appropriate sites
var entries = doc.getElementsByTagName('item');
var count = Math.min(entries.length, maxFeedItems);
for (var i = 0; i < count; i++) {
item = entries.item(i);
// Grab the title for the feed item.
var itemTitle = item.getElementsByTagName('title')[0];
if (itemTitle) {
itemTitle = itemTitle.textContent;
} else {
itemTitle = "Unknown title";
}
// Grab the link for this feed item
var itemLink = item.getElementsByTagName('link')[0];
if (itemLink) {
itemLink = itemLink.textContent;
} else {
itemLink = "Unknown link";
}
var title = document.createElement("a");
title.className = "item_title";
title.innerText = itemTitle; //display title in iframe
title.addEventListener("click", titleLink); // should open link when clicking on title, but does not.
}
// -------------------------------------------------------------------
// Show |url| in a new tab.
function showUrl(url) {
// Only allow http and https URLs.
if (url.indexOf("http:") != 0 && url.indexOf("https:") != 0) {
return;
}
chrome.tabs.create({url: url});
}
function moreStories(event) {
showUrl(moreStoriesUrl);
}
function titleLink(event) {
showUrl(itemLink);
}
Any thoughts on why this is not working.
If I replace title.addEventListener("click", titleLink); with title.addEventListener("click", moreStories); each title will link to moreStories, I cannot get each title to link to itemLink.
Thanks
Its a bit hard to answer your question without the whole code, but Ill give it a shot ;)
First up, titleLink() isnt going to work because itemLink isnt known. When you create title (the link) you should of attached it to that...say title.href=itemLink then in tiltleLinks you could access that href with showUrl(event.currentTarget.href)
Also did you fix the error in that example?...if not then change frameLoaded to....
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var clssName = links[i].className;
if (clssName != "item_title" && clssName != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
If you still have probs could you attach the whole code so I can see what your doing and Ill give you a hand.
Thank you very much for your help.
code title.href=itemLink and code showUrl(event.currentTarget.href) was exactly what I needed.
For completeness, here is the full code,
<script id="iframe_script">
function reportHeight() {
var msg = JSON.stringify({type:"size", size:document.body.offsetHeight});
parent.postMessage(msg, "*");
}
function frameLoaded() {
var links = document.getElementsByTagName("A");
for (i = 0; i < links.length; i++) {
var class = links[i].className;
if (class != "item_title" && class != "open_box") {
links[i].addEventListener("click", showStory);
}
}
window.addEventListener("message", messageHandler);
}
function showStory(event) {
var href = event.currentTarget.href;
parent.postMessage(JSON.stringify({type:"show", url:href}), "*");
event.preventDefault();
}

reportHeight();
