With Authentication

[Super bunso]

I was able to try the demo for the leaderboard..now I want to add authentication.. now I can login to google play as authentication and make login for firebase.. I have uid.. question is 

how I can add it to demo? also the leaderboard controller seem only for public..I try to change the firebase-db-rules.txt but still denied.. 

also possible to get all the other scores? 

[Super bunso]

any?

Hi Super Bunso, thanks for reaching out!

First a note to be clear: Changing the text in firebase-db-rules.txt won't do anything, as it is merely a file to contain the rules text to copy and paste into the Firebase Console. In order to change the rules for your DB, you will have to log in to the console, select your project, open the Database section and navigate to Rules. That is where changes to the rules are registered.

If you want to use Firebase Auth, I would recommend using the rules in firebase-db-auth-rules.txt. What this does is leave the reading of scores public to anyone (so you will be able to read other users scores, necessary for the leaderboard), but only allows writes if the user_id field of a new score matches the auth.user_id variable built in to Firebase Database rules' syntax.

This question makes me realize that there should probably be a "username" field on the score records as well, since UID is not the best public representation of a user on the leaderboard itself. I will add that as a task for the repo. 

Please follow up on whether this helps, or if you need any more details on auth or any other aspect of the leaderboard. Good luck!

Best,

DZ

From your comment on the blog I see that you also changed the rules in the Firebase Console, so please disregard that part.

In that case I don't see any immediate reason to still be getting the access denied error. Did you follow the setup steps to authenticating your unity project with firebase here?

Perhaps you could post the full error message so that I can get more details of what exactly is going on.

Best,

DZ

yes I follow the steps I already have uid.. but I dont use p12 cause thats from ios right? I'm only using it for android and im in windows pc btw.. 

here is the rules I use in the firebase console not sure if it the correct one 

{

  "rules": {

   "$uid": {

        ".write": "$uid === auth.uid",

        ".read": true,

      }

  }

}

[Dane Liergaard]

Hi, you do need to use the p12 key regardless of OS, but only in the editor so that you can upload test scores without needing to be authorized as the test user.

Also, the LeaderboardController attempts to read the scores from the "all_scores" path (unless you change that in the inspector). Try these rules in the Firebase console:

{
	"rules": {
	"all_scores": {
	".indexOn": ["score", "user_id"],
	".read": "true",
	".write": "newData.child('user_id') == auth.uid"
	}
	}
	}

[Super bunso]

thank you for reply .. I dont have the p12 key cause im using windows.. that why I'm directly testing in from device.. btw I gonna try this one.. thanks

[Dane Liergaard]

Hi, no problem! Please let me know whether those rules help or not.

Regarding the P12 key, please see this setup step for Firebase Realtime Database, which is what allows in-editor authorization to be able to upload scores while ignoring the normal auth rules. Once you've verified that the auth rules work for individual users, this will give you more freedom to test things in-editor instead of having to build and test on device in all cases. It is consistent across operating systems, so working on Windows shouldn't be different from working on Linux or Mac.

Hi I got error in firebase when changing the rules 

Error saving rules - Line 12: Invalid == expression: left operand is not a number, boolean, string, null.

[Super bunso]

I change to rule like this to fix the error in firebase console 

{

  "rules": {

    "all_scores": {

      ".indexOn": ["score", "user_id"],

      ".read": "true",

      ".write": "newData.child('user_id').isString() == auth.uid"

    }

  }

}

but when testing in device i got this log in during sending score

I also try to get P21 file  but it was not found not sure why.. I attached a screenshoot 

[Dane Liergaard]

Thanks for the correct rules and the screenshot, those are both very helpful. For for the file, please try putting the entire filename in the LeaderboardController's field, including the file extension (in this case, sampleP12.p12). Let me know if that works.

Best,

DZ

Hi Super, sorry for the delay - Google Next was last week and everyone was heads-down preparing for that the week before. I am back at work this week and haven't had a chance to return to this yet, but just wanted to check in to let you know it's still on my radar. Let me know if you have gotten it figured out as well, and I can add some documentation to hopefully prevent anyone else from having the same issue in the future.

Best,

DZ

Hi Super, to be clear, did you get the service account email from either the IAM page on the cloud console (https://console.cloud.google.com/iam-admin/iam) or by finding it in the service account settings in the firebase console, like in the following screenshot?

Thanks,
