Authenticate with LinkedIn api using javascript issues - javascript

Using the Linkedin Tutorial, I'm trying to login to LinkedIn using Javascript.
The issue I have: using firebug for verification I realize that the http request does not show errors, but the LinkedIn Button is not rendered and the http response is:
(function(){
var r=("true" === "false"), a=("false" === "false"), h=[], e=("false" === "true");
var p="${SCOPE_NAME}";
var s=("SCOPE_VALID" === "SCOPE_INVALID"), n=("SCOPE_VALID" === "SCOPE_NOT_AUTHORIZED"),
d=("SCOPE_VALID" === "SCOPE_DISABLED");
if(e){
throw new Error("An error occurred.");
}
else if (!a) {
throw new Error("API Key is invalid");
}
else if (s) {
throw new Error("Scope parameter is invalid: " + p);
}
else if (n) {
throw new Error("Scope parameter is not authorized: " + p);
}
else if (d) {
throw new Error("Scope parameter is disabled: " + p);
}
else if (h.length == 0) {
throw new Error("You must specify a valid JavaScript API Domain as part of this key's
configuration.");
}
else if (!r) {
throw new Error("JavaScript API Domain is restricted to "+h.join(", "));
}
else {
throw new Error("Unknown Error");
}
})();
Can you assist me in solving this issue?

Go to https://www.linkedin.com/secure/developer
Click on the application name you're using.
Add your domain name('http://www.example.com') or if you are using
localhost then add ('http://localhost') to JavaScript API Domains:

How do I send a request to a discord webhook

I'm trying to add webhook integration for my reminder site, this is my current code and it doesn't work, what do I need to fix?
When I submit the webhook, it gives me the error set for an input with the length of 0.
var webhookInput = document.getElementById('webhookInput');
var webhookButton = document.getElementById('webhookBtn');
var webhook = webhookInput.value;
async function webhookRequest() {
try {
const response = await fetch(webhook);
if (response.status === 200) {
console.log('webhook valid');
localStorage.setItem('webhook', webhook);
}
else {
alert('Please make sure your webhook is valid.');
}
}
catch (err) {
console.log(err);
}
}
webhookButton.addEventListener('click', function() {
if (webhook.length > 0) {
webhookRequest();
}
else if (webhook.length === 0) {
alert('Please enter a webhook.');
}
else {
alert('Error.');
}
});
Your code is correct and works, sending a GET to a webhook URL will yield a 200 code if the webhook exists and the credentials are correct. You're likely using a channel link instead, to create a webhook edit a channel and go to:
Integrations -> Webhooks -> Create Webhook -> New Webhook

Getting a wrong Error response in catch block when using along with async await

async function run() {

);
const { verified, message } = data;
if (verified === false) throw new Error('VARIFICATION_FAILED');
else throw new Error('VARIFICATION_SUCCESS');
} catch (err) {
if (err.message === 'VARIFICATION_FAILED')
throw new Error('VARIFICATION_FAILED');
else if (err.message === 'VARIFICATION_SUCCESS')
throw new Error('VARIFICATION_SUCCESS');

}
}
await run();
hi i was trying to get the error in catch(err) block if in case the VarifyPanDetails api above fails , but when it does it giving enter image description here if u console it, but network tap its showing enter image description here ,
how its not showing the throwing the same error as network tab i.e err in the console should have err.status===400 and err.message==="Invalid PAN Number" but instead of that its showing err.message:Error.false

Application infinite loop with processMessage failed error

My Cordova app not running in browser and mobile it shows an error
processMessage failed
Screenshot:
and goes infinite loop and it freezes the device any solution?
This question is already in asked here Cordova not running normally but there is not an answer so thats why I have to asked it again.
Getting the same issue (using Chrome with the phonegap desktop emulator. What I see as happening is this.
There seems to be a bug in Cordova.js that fails to check for an empty message.
When the app sends out alerts:
gap_init:2
gap:[0,"StatusBar","_ready","StatusBar1593157203"]
gap:[0,"App","show","App1593157204"]
gap:[0,"File","requestAllPaths","File1593157205"]
gap:[0,"NetworkStatus","getConnectionInfo","NetworkStatus1593157206"]
gap:[0,"Device","getDeviceInfo","Device1593157207"]
and you just hit 'OK', instead of clearing out the contents of that dialog box it going on to cause an infinite loooooop. I don't know the significance of these messages yes as I'm pretty new to Cordova, but it's hell and gone from the principle of least surprise!
So you can clear out the messages, or modify the cordova.js code where it gets stuck in the loop. You also could turn off the alerts that also works.
the function processMessage() (see below) doesn't test for an empty string, which in and of itself might be fine, but it is called from a while loop which only checks for "*" if its going to pop.
while (messagesFromNative.length) {
var msg = popMessageFromQueue();
// The Java side can send a * message to indicate that it
// still has messages waiting to be retrieved.
if (msg == '*' && messagesFromNative.length === 0) {
setTimeout(pollOnce, 0);
return;
}
processMessage(msg);
}
// Processes a single message, as encoded by NativeToJsMessageQueue.java.
function processMessage(message) {
try {
var firstChar = message.charAt(0);
if (firstChar == 'J') {
eval(message.slice(1));
} else if (firstChar == 'S' || firstChar == 'F') {
var success = firstChar == 'S';
var keepCallback = message.charAt(1) == '1';
var spaceIdx = message.indexOf(' ', 2);
var status = +message.slice(2, spaceIdx);
var nextSpaceIdx = message.indexOf(' ', spaceIdx + 1);
var callbackId = message.slice(spaceIdx + 1, nextSpaceIdx);
var payloadKind = message.charAt(nextSpaceIdx + 1);
var payload;
if (payloadKind == 's') {
payload = message.slice(nextSpaceIdx + 2);
} else if (payloadKind == 't') {
payload = true;
} else if (payloadKind == 'f') {
payload = false;
} else if (payloadKind == 'N') {
payload = null;
} else if (payloadKind == 'n') {
payload = +message.slice(nextSpaceIdx + 2);
} else if (payloadKind == 'A') {
var data = message.slice(nextSpaceIdx + 2);
var bytes = window.atob(data);
var arraybuffer = new Uint8Array(bytes.length);
for (var i = 0; i < bytes.length; i++) {
arraybuffer[i] = bytes.charCodeAt(i);
}
payload = arraybuffer.buffer;
} else if (payloadKind == 'S') {
payload = window.atob(message.slice(nextSpaceIdx + 2));
} else {
payload = JSON.parse(message.slice(nextSpaceIdx + 1));
}
cordova.callbackFromNative(callbackId, success, status, [payload], keepCallback);
} else {
console.log("processMessage failed: invalid message: " + JSON.stringify(message));
}
} catch (e) {
console.log("processMessage failed: Error: " + e);

Check your cordova js loading properly? is the path for cordova js is proper?
give path like this in your index.html:
<script type="text/javascript" src="cordova.js">
I had the problem in an Angular 6 project. It was simply solved by deleting cordova.js which was under src folder.
I was not able to resolve this issue when viewing the /android platform option for cordova serve; however, the /ios platform option did function properly.
Not much of a solution, but perhaps a mildly helpful workaround for those who follow.

How to build Twitter OAuth authentication?

This is my JavaScript code for following operation: https://api.twitter.com/1.1/users/show.json?screen_name=barackobama

Thanks for any Help!

According to the new version Twitter API v1.1 all requests to Twitter must be signed by using OAuth 1.0A. You may want to visit here to see how it works. I would suggest to use Twitter libraries to authenticate and sign your requests like codebird-js(have a look at the examples below or at the website given). It's really easy to use. To authenticate is as simple as below:
var cb = new Codebird;
cb.setConsumerKey('YOURKEY', 'YOURSECRET');
cb.setToken('YOURTOKEN', 'YOURTOKENSECRET');
and then make calls e.g. tweet:
cb.__call(
'statuses_update',
{'status': 'Whohoo, I just tweeted!'},
function (reply) {
// ...
}
);
Hope it helps.

How can I get the SSL Certificate info for the *current* page in a Firefox Add On

I'm trying to develop a Firefox extension/add-on that needs access to the SSL Certificate information of the page that is currently loaded. Once I have this information I plan on modifying the contents of the page based on the SSL information. Though, before I get there I first need to get the SSL info.
The approach outlined here makes a separate XMLHTTPRequest to get the security certificate. I would rather not do that if I could avoid it because it presents a security problem.
For example, a malicious site/man-in-the-middle could provide one certificate on the first request for the page (which the browser would verify) and then provide another certificate for the XMLHTTPRequest that my extension would make. This would result in the extension modifying site contents based on inconsistent information. Hence, I'd like to get the SSL Cert information that the browser itself used when verifying the site.
With that in mind I combined the above approach with the method outlined in Altering HTTP Responses in Firefox Extension to intercept all the HTTP responses by adding an observer of the "http-on-examine-response" event. I thought that with this method I could simply grab the cert info as it was being downloaded from the site.
Here is the meat of my code, much of it taken from the above links (the rest is Firefox extension boilerplate):
function dumpSecurityInfo(channel) {
const Cc = Components.classes
const Ci = Components.interfaces;
// Do we have a valid channel argument?
if (! channel instanceof Ci.nsIChannel) {
dump("No channel available\n");
return;
}
var secInfo = channel.securityInfo;
// Print general connection security state
if (secInfo instanceof Ci.nsITransportSecurityInfo) {
dump("name: " + channel.name + "\n");
secInfo.QueryInterface(Ci.nsITransportSecurityInfo);
dump("\tSecurity state: ");
// Check security state flags
if ((secInfo.securityState & Ci.nsIWebProgressListener.STATE_IS_SECURE) == Ci.nsIWebProgressListener.STATE_IS_SECURE)
dump("secure\n");
else if ((secInfo.securityState & Ci.nsIWebProgressListener.STATE_IS_INSECURE) == Ci.nsIWebProgressListener.STATE_IS_INSECURE)
dump("insecure\n");
else if ((secInfo.securityState & Ci.nsIWebProgressListener.STATE_IS_BROKEN) == Ci.nsIWebProgressListener.STATE_IS_BROKEN)
dump("unknown\n");
dump("\tSecurity description: " + secInfo.shortSecurityDescription + "\n");
dump("\tSecurity error message: " + secInfo.errorMessage + "\n");
}
// Print SSL certificate details
if (secInfo instanceof Ci.nsISSLStatusProvider) {
var cert = secInfo.QueryInterface(Ci.nsISSLStatusProvider).
SSLStatus.QueryInterface(Ci.nsISSLStatus).serverCert;
dump("\nCertificate Status:\n");
var verificationResult = cert.verifyForUsage(Ci.nsIX509Cert.CERT_USAGE_SSLServer);
dump("\tVerification: ");
switch (verificationResult) {

dump("OK");

"http-on-examine-response", false);
}
};
window.addEventListener("load", function () { test.run(); }, false);
What I found is that this implementation is inconsistent. When I load gmail.com in Firefox I'll sometimes get the certificate information and sometimes I won't. I suspect this is a caching issue as refreshing the page will usually result in the certificate information being downloaded/printed.
For my intended application this behavior is not acceptable. This is for a research project so, if I have to, I would be willing to modify the Firefox source code, but my preference would be to do this using the extension/add-on API.
Is there a better, more consistent way to get the SSL Certificate information?
Building on this answer:
The trick is to register a progress listener and check aState when the onSecurityChange function is called. If the Ci.nsIWebProgressListener.STATE_IS_SECURE flag is set then the page is using an SSL connection. That isn't enough however, the aRequest parameter may not be an instance of Ci.nsIChannel, that should be verified first with if (aRequest instanceof Ci.nsIChannel).
Here is the working code:
function dumpSecurityInfo(channel) {
const Cc = Components.classes
const Ci = Components.interfaces;
// Do we have a valid channel argument?
if (! channel instanceof Ci.nsIChannel) {
dump("No channel available\n");
return;
}
var secInfo = channel.securityInfo;
// Print general connection security state
if (secInfo instanceof Ci.nsITransportSecurityInfo) {
dump("name: " + channel.name + "\n");
secInfo.QueryInterface(Ci.nsITransportSecurityInfo);
dump("\tSecurity state: ");
// Check security state flags
if ((secInfo.securityState & Ci.nsIWebProgressListener.STATE_IS_SECURE) == Ci.nsIWebProgressListener.STATE_IS_SECURE)
dump("secure\n");
else if ((secInfo.securityState & Ci.nsIWebProgressListener.STATE_IS_INSECURE) == Ci.nsIWebProgressListener.STATE_IS_INSECURE)
dump("insecure\n");
else if ((secInfo.securityState & Ci.nsIWebProgressListener.STATE_IS_BROKEN) == Ci.nsIWebProgressListener.STATE_IS_BROKEN)
dump("unknown\n");
dump("\tSecurity description: " + secInfo.shortSecurityDescription + "\n");
dump("\tSecurity error message: " + secInfo.errorMessage + "\n");
}
else {
dump("\tNo security info available for this channel\n");
}
// Print SSL certificate details
if (secInfo instanceof Ci.nsISSLStatusProvider) {
var cert = secInfo.QueryInterface(Ci.nsISSLStatusProvider).
SSLStatus.QueryInterface(Ci.nsISSLStatus).serverCert;

The way you query the channel to get its security info seems sane. I suspect that your problem is actually timing - you query it at the wrong time. Tracing all requests is really the wrong approach if security info is all you are interested in. It makes far more sense to register a progress listener (there are examples) and to look at the channel whenever onSecurityChange is being called. You are likely to be only interested in requests where aState contains STATE_IS_SECURE flag. Note that aRequest parameter is usually an nsIChannel instance but could also be a plain nsIRequest - instanceof check is required.
