Facebook Test User vs "real" user - javascript

I'm developing an App with the Javascript and PHP SDK's. The javascript logs the user in, then passes off to the PHP code for most of the work.
The problem that I'm having is that test users and "real" users work differently. I'm calling FB.login, with scopes beyond the standard:
FB.login( function(response) {
if (response.authResponse) {
handleLoginStatusChange(response);
} else {
console.log('User cancelled login or did not fully authorize.');
}
},
{
scope: 'email,public_profile,manage_pages',
return_scopes: true
});
When this runs for the test user's account, the javascript presents two permissions windows - the first one for "public profile and email address", click "Okay", and I get a second one "manage your Pages". No warnings. And my app proceeds normally.
When I run it on a "real" account, the second window doesn't pop up, so my app doesn't have permissions to manage pages. Any idea why the two accounts would be behaving this way?

As CBroe pointed out, the App hadn't been properly reviewed. Thanks.

PWA blank page Facebook

I have a PWA app where one of the options you have to sign-in is Facebook, everything goes well and if you're in the browser the login works really well. The problem happens when you add the website to your mobile and it opens in PWA and you click log-in from Facebook it opens a blank page and it doesn't redirect to the app, if you close the page, go back to the app and click again facebook the user is logged in, but does anyone has any idea how to get rid of the white/blank page?
I have tried 'redirect_uri' and 'display: touch,' but none of this seems to be working anymore.
A blank page after login is a common problem when using Facebook as a sign-in method, especially when we’re in development mode.
It happens because you already logged in and authorized the app, so when it tries to log-in again, it goes blank.
The most straightforward way to fix this is first to check if the user has already logged in and authorized your app before calling the .login() function.
Luckily, Facebook provides a function to do it, where they handle (almost) everything for you.
The getLoginStatus() function
The getLoginStatus() functions determines 1) if a user is signed into Facebook and 2) if the user has already authorized your app.
There are three possible states for a user:
The user is logged into Facebook and has authorized your app, in this case, the function will return: connected.
The user is logged into Facebook but has not authenticated your application, in this case, the function will return: not_authorized.
The user is either not logged into Facebook or explicitly logged out of your application, in this case, we don’t know which one is it, that’s why it returns: unknown.
For example:
When we call getLoginStatus() we’ll get an object similar to this:
{
authResponse: {
userID: '12345678912345',
accessToken: 'kgkh3h4gkh3g4k2h4gk23h4gk2h34gk234gk2h34AndSoOn',
session_Key: true,
expiresIn: '5183738',
sig: '...'
},
status: 'connected'
}
There you can see there’s an authResponse object and a status object. We’ll focus on the status object first, checking for each of the three possible responses.
this.facebookProvider.getLoginStatus(response => {
if (response.status === 'connected') {
// User Authenticated and your App is authorized
} else if (response.status === 'not_authorized') {
// User authenticated but your app isn't authorized yet.
} else {
// the user isn't logged in to Facebook.
}
});
Try this and try to logout first from Facebook before you make call from PWA.

Gating content with JavaScript (Netlify Identity): Content flashes in slow connections, how to only load it after log in check?

I am not really a web app developer and I would like to ask about best practices for gating website content.
I am preparing to deploy documentation created with mkdocs. It uses Netlify Identity because with that Github auth is available without any coding.
My current solution: I have added the Netlify Identity script in head and the login/logoff button via template addons in mkdocs, and then created a static document /login/ (that gets picked up automatically in mkdocs but does not get generated with template).
In the standard template there is a JS redirect to /login/ unless user is logged in:
if (window.netlifyIdentity) {
window.netlifyIdentity.on("init", user => {
if (!user) {
document.location.href = "/login/";
}
});
}
On the static page there is a redirect to / only just after user has logged in:
if (window.netlifyIdentity) {
window.netlifyIdentity.on("init", user => {
if (!user) {
window.netlifyIdentity.on("login", () => {
document.location.href = "/";
});
}
});
}
I hope this is a reasonable way to go about it. The docs do not store anything critical but I still wouldn't want that content exposed.
But I have noticed on slow connection the redirect takes a second or two so when a deep URL is accessed the content flashes on the screen before login.
What can be done to stop this and load the content only after the login check is performed?
This is not going to work as you desire and is not secure.
If I wanted to read your content without an account, I could simply disable JavaScript in my browser (a few mouse clicks) and your site would load, but the redirect would never run.
Regardless, with JavaScript enabled, the way it works is that the browser downloads the page, then downloads any resources (including scripts), and then finally runs any scripts. There is no way to change that. Of course, on a fast system, the user may not perceive a delay, as the delay is very short, but there is always a delay. That is how browsers work.
If you don't want your users to have access to the information until after they are logged in , then you must not send the information out until they are logged in. In other words, you need to configure your server to not send the page at all until it receives verification that the user has permission to receive that information. How you do that depends on which server you are using among other things, which would be the subject of a separate question.
I know this is a old post but you can use netlify functions combined with a netlify redirect file.
You would have to set a role of a user when signing up using the metadata, you could do this with a netlify function thats hooked into netlify identity, more here.
Create a function called identity-signup.js when a user signs up this function is automatically called.
exports.handler = async (event) => {
const { user } = JSON.parse(event.body)
// you could do something with the user here: eg console.log(user.email)
// or using stripe: const customer = await stripe.customers.create({ email: user.email });
return {
statusCode: 200,
body: JSON.stringify({
app_metadata: {
roles: ['free']
}
})
}
}
Once you have a role you can simply create a _redirects file like so:
/authedcontent/* 200! Role=free
/authedcontent/ / 404
Later down the line you can extend the netlify function to save the users detail in an external database or maybe setup a stripe subscription.
The only caveat is that this requires a paid netlify account.

Other browser windows don't go back to user login page after Meteor.logout()

I have written a meteor application with user login. After a user logs out, the application redirects to the user login page. However, when they are multiple tabs in the browser (or multiple browser windows) where the application is active (and the user is logged in), only the active tab or browser window goes back to the user login page. In the other window it seems the user is still logged in. However, when the user does some further work in the other window, nothing is synced with the db on the server anymore. I thought Meteor.logout() is reactive, so how is it possible that the other browser tabs or windows don't refresh?
I have the folowwing in my router?js file:
var filters = {
isLoggedIn : function(pause) {
if(!Meteor.user()){
this.render('login');
} else {
this.next();
}
}
....
}
Router.onBeforeAction(filters.isLoggedIn);
After pushing the logout button the following js code is executed
Meteor.logout();
Thanks for the help.
Try this:
Meteor.logoutOtherClients
Meteor.logoutOtherClients should log out all sessions. It is designed for situations where the user is logged in on multiple devices and wants to log out on all of them simultaneously.
In my app I didn't want to use a global redirect on logout, but on some templates to redirect to another template if logout happens.
Following Autumn Leonard's comment, I made this work by having the particular template reactive by creating a template.mytemplate.onCreated function and inside there put an autorun function checking Meteor.user() and doing the redirect.
I hope this approach helps others :)

Google Javascript Client library OAUTH asks for Offline Access permission, though it was never requested

My application interacts with Google with Javascript only. It asks for user profile access, email access and contacts management permissions.
Upon loading a page, the application checks if the user has already granted those permissions and obtains an access token if he had.
Here is some sample code:
var GoogleContacts = {
...
checkAuth: function(){
gapi.auth.authorize({
client_id: googleKeys.clientId,
scope: googleKeys.scopes,
immediate: true
},
jQuery.proxy(this.handleAuthResult, this)
);
},
askAuth: function(){
gapi.auth.authorize({
client_id: googleKeys.clientId,
scope: googleKeys.scopes,
immediate: false
},
jQuery.proxy(this.handleAuthResult, this)
);
}
...
}
....
function handleGoogleApiLoad(){
gapi.client.setApiKey(googleKeys.apiKey);
gapi.auth.init(function(){console.info('popup api ready')});
setTimeout(function(){GoogleContacts.checkAuth();}, 300);
}
....
$('#emailButton').click(function() {
if(!accessToken)
GoogleContacts.askAuth();
...
});
Now, if user comes for the first time, he is asked the correct permissions when he pressed the "Send email" button. When user reloads a page, the seamless permissions check returns failure and when user hits a "send email" button, we open the Google authorization popup again, and it now asks for Offline Access permission.
This seems incorrect as the JS api has no actual use for offline access.
Looks like this problem started after Google released the incremental auth feature: http://googleplusplatform.blogspot.co.il/2013/12/google-sign-in-improvements11.html
Is this a bug that will soon be fixed, or should we change the code somehow to not confuse our users with weird permission requests?
Update:
I have tried to use the plus api and gapi.auth.signIn() method but with the same result.
Apparently, this problem is scope-dependant, as when I use only the login scope, everything works as expected, but adding the Google Contacts access scope https:||www.google.com/m8/feeds/ always leads to the Offline Access request when entering page second time. Here is a fiddle to confirm this: http://jsfiddle.net/hjLM6/6/
This must be a bug and I really would like Google to deal with it soon, as it scares users away.
The immediate:false parameter in your askAuth method is the cause. The post that Abraham mentions explains the background.
The gapi.auth.authorize() method should generally be avoided in most cases now that the gapi.auth.signIn() method is available to handle programatic initiation of the authorization flow and also you should make use of the dynamic callbacks. The information on monitoring a user's session state explains how and when to get your sign-in callback function to fire and how you can use the values within the auth result object to determine if they've previously authorized your app, signed in (or out) of your app, or signed in (or out) of google.
Your checkAuth and askAuth functions would effectively be combined to check the status of the auth result object and act accordingly. Your email button click event would trigger instead gapi.auth.signIn() with the necessary parameters and scopes for your app.
I just had exactly the same issue with drive.readonly scope, for what it's worth the way I worked around it is by always calling authorize with immediate = false. This isn't that bad because when you do this for an already authorized user, Google will open the popup for a fraction of a second but then will immediately close it (apparently making use of the chance to open the popup in the browser event handler in case the user does need to authorize).
Curiously, for localhost server where I previously used immediate = true, I continue to see requests for offline access - but on the production server I haven't seen seen them so far, fingers crossed.

Facebook login without Popup window

I am using below code for Facebook login.
function login(){
FB.login(function(response) {
if (response.authResponse) {
FB.api('/me', function(response) {
alert(JSON.stringify(response))
});
} else {
console.log('User did not authorize.');
}
});
}
I am calling login method on click of button.FB.login() call is giving a popup window where user is supposed to enter username and password.
My requirement is to do a silent login i.e. logging in without popup window.My username and pswd are hardcoded for time being.How do i pass the credentials to login API without user intervention.I know hardcoding is not good practice but later i will obtain credentials from user controls.
How do i achieve this.Any help is greatly appreciated.
You can't. The frame that hosts the login is an iFrame displaying a form page hosted on Facebook. Facebook doesn't want computers logging people into their site for various anti-spam, security reasons.
This is not possible for several reasons
It is against Facebook's Policy to give credentials to third parties
Users should always be able to verify the identity of the page they are giving their credentials to.
I'm sure you don't want to require your users to break the policy do you?
