Is Facebook Login Implemented?

[diasleo98]

I was taking a look on how to implement Facebook Login with Parse and found out that ParseFacebookUtils is not presented in the project and found no implementation what so ever of it. Is it implemented?

[TobiasPott]

No, the facebook utils are no longer part of the master branch.
If you want to check them out you would need to dig in past commits (e.g. those made for version 1.7 or earlier).

In my case, i’ve already implemented the Facebook login with the Xamarin.Auth package, after I sign up with the Facebook account, how do I link it with a new parse user? Because when i create a new parse user i need to provide a password as well, in the facebook case it is not needed. My question is the same for when I log in with Facebook, how do I log in with Facebook without the ParseUser password

And in this 2.0 pre-release, are Push Notifications now implemented?

[TheFanatr]

I will address the lack of ParseFacebookUtils soon.

@TobiasPott Where did the 1.8.0 branch go? I needed that for reference. Release 1.7.0 contains the source for that release obviously, but the 1.8.0 branch had some extra changes in it that the previous maintainers were working on. Would prefer to have that in a "old-codebase" branch or something if you still have access to a copy. The source I currently have access to will do fine for now though. Will implement a login utilities file soon as well as live query.

The infrastructure does exist but I have no idea if it works or is usable; will have to test.

[TheFanatr]

Just to be clear, any OS-or-platform-specific code is not present in the current codebase. Will have to add this back in some form later.

[TheFanatr]

@diasleo98 Please build and reference the develop branch, then instantiate ParseClient with a FacebookAuthenticationMutator with the Caller set to the App ID from Facebook. You can then use Parse.Infrastructure.Utilities (Parse.Utilities in the future) and call await aParseClient.AuthenticateWithFacebookAsync(facebookId, accessToken, invalidationTime, cancellationToken). You should have access to facebookId (the user's identifier on Facebook), accessToken, and invalidationTime from the result of successful authentication calls to Facebook's OAuth APIs. That should be able to authenticate a user with Facebook for the Parse SDK.

[TheFanatr]

I will add the convenience utilities for individual environments back some time in the near future, in order to eliminate the need to call into a service's OAuth APIs with external utilities such as Xamarin.Auth.

[TheFanatr]

For now, someone needs to test this, because I don't have a Facebook test environment. You will need the latest .NET 5 installed.

[TobiasPott]

@TheFanatr I'll try to give it a go during this week and check how to get access to the facebook SDK and an environment for testing it.
Could you elaborate which the latest .NET 5 version needs to be installed? Is it required specific for the facebook auth option or due to other changes you made to develop?

@TheFanatr didn't got your question about the 1.8.0 branch. I've deleted it as I assumed it was obsolete and never have been gone anywhere. I've a backup copy and will put it back into the main repository asap and let you know when I've done so.
I'm very sorry for taking your reference.

[TobiasPott]

@TheFanatr I've pushed the 1.8.0 legacy codebase to https://github.com/parse-community/Parse-SDK-dotNET/tree/legacy-codebase/1.8.0
I've also added 1.7.0 as a separate branch according to its tag in the history (I cannot resemble whether or not any later commit got into the actual version 1.7.0 release on nuget).

[TheFanatr]

@TobiasPott Perfect! No worries; I was using 1.8 as a reference because it was to be a fallback for the master branch if for some reason the Parse admins decided to revert the initial 2.0 refactor, so I assumed it was the best branch to base off of. Also, I believe the old maintainers had started or continued a modularization effort in it before it went stale, so it's a better source of code to take back over into master when needed, as issues from 1.7 could have been fixed.

[TheFanatr]

Could you elaborate which the latest .NET 5 version needs to be installed?

The latest preview of .NET 5 can be found on the .NET website by clicking on the link to the installer or binaries for your platform under the latest version listed.

Is it required specific for the facebook auth option or due to other changes you made to develop?

It is due to the use of C# 9 features in the added and modified code. It at least needs the latest .NET Core CLI.
