Autorisation de base de données Android Firebase refusée malgré le fait qu'un utilisateur est connecté

Question

Je n'ai jamais utilisé la base de données Firebase et je pense que je rencontre des problèmes de "débutant" et que je ne peux pas résoudre le problème. Obtenir au point:

Ma base de données est structuré comme suit:

database 
/cookbooks 
    /key: cookbook id, value: CookBook.class 
     /recipes 

/recipes 
    /key: recipe id, value: Recipe.class 
/users 
    /cookbooks 
     /cookbook id 

Ce que je veux réaliser est que le début des données d'application est téléchargée à partir de ces dépôts (de tous) et stockés dans une classe DataManager.

Voici les règles dans ma base de données:

{ 
    "rules": { 
    "recipes-309da": { 
     "cookbooks": { 
     ".read": "auth != null", 
      ".write": "auth != null", 
    }, 

    "recipes": { 
     ".read": "auth != null", 
      ".write": "auth != null", 
    }, 

    "users": { 
     "$uid": { 
      ".read": "auth != null", 
       ".write": "auth != null", 
     } 
    } 
    } 
} 
} 

Le problème est que je suis garder "permission denied" notification. Les données ne sont pas téléchargées et je ne peux enregistrer aucune donnée dans la base de données.

Je serais reconnaissant pour toute aide que vous pourriez me donner!

Certains code correspondant:

public static final String STORAGE_PATH_PHOTOS_UPLOADS = "photos_uploads/"; 
    public static final String DATABASE_PATH_PHOTOS_UPLOADS = "photos_uploads"; 
    public static final String DATABASE_PATH_RECIPES_UPLOADS = "recipes"; 
    public static final String DATABASE_PATH_COOKBOOKS_UPLOADS = "cookbooks"; 
    public static final String DATABASE_PATH_USERS = "users"; 

private StorageReference mStorageReference = FirebaseStorage.getInstance().getReference(); 
    private DatabaseReference mDatabasePhotosUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_PHOTOS_UPLOADS); 
    private DatabaseReference mDatabaseRecipesUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_RECIPES_UPLOADS); 
    private DatabaseReference mDatabaseCookBooksUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_COOKBOOKS_UPLOADS); 
    private DatabaseReference mDatabaseUsersUploads = FirebaseDatabase.getInstance().getReference(ConstantsForUploads.DATABASE_PATH_USERS); 

    private DatabaseReference mDatabaseRecipesUploadsBelowUser = mDatabaseRecipesUploads.child(FirebaseAuth.getInstance().getCurrentUser().getUid()); 
    private DatabaseReference mDatabaseCookBooksKeyUploadsInUserBooks = mDatabaseUsersUploads.child(FirebaseAuth.getInstance().getCurrentUser().getUid()).child("books"); 

Au début de MainActivity J'utilise une méthode attachListeners (ALL) de GeneralDataManager.

public void attachListeners(int staticIntFromGeneralUploader) { 
    // attaches and detaches SingleValueEventListeners so it can download data while opening an app 
    mDatabaseRecipesUploadsBelowUser.addListenerForSingleValueEvent(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      mCurrentUserRecipesList = new ArrayList<>(); 
      mCurrentUserRecipeTitleKeyMap = new HashMap<>(); 

      for (DataSnapshot snapshot : dataSnapshot.getChildren()) { 
       Recipe recipe1 = snapshot.getValue(Recipe.class); 
       mCurrentUserRecipesList.add(recipe1); 
       mCurrentUserRecipeTitleKeyMap.put(recipe1.getTitle(), snapshot.getKey()); 
      } 
     } 

     @Override 
     public void onCancelled(DatabaseError databaseError) { 

     } 
    }); 

    mDatabaseCookBooksUploads.addListenerForSingleValueEvent(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      mRecipesInCookBooksMap = new HashMap<>(); 

      for (DataSnapshot snapshotOfCookBooks : dataSnapshot.getChildren()) { 
       String cookBookKey1 = snapshotOfCookBooks.getKey(); 

       if (mCurrentUserCookBookKeyTitleMap.containsKey(cookBookKey1)) { 
        CookBook cookbook1 = snapshotOfCookBooks.getValue(CookBook.class); 
        for (DataSnapshot snapshotOfRecipesInsideCookBooks : snapshotOfCookBooks.getChildren()) { 
         if (snapshotOfRecipesInsideCookBooks.getValue() == Recipe.class) { 
          Recipe recipe1 = snapshotOfRecipesInsideCookBooks.getValue(Recipe.class); 
          if (!mRecipesInCookBooksMap.containsKey(cookbook1)) { 
           mRecipesInCookBooksMap.put(cookbook1, new ArrayList<Recipe>()); 
           mRecipesInCookBooksMap.get(cookbook1).add(recipe1); 
          } else { 
           mRecipesInCookBooksMap.get(cookbook1).add(recipe1); 
          } 
         } 

        } 
       } 
      } 

      for (CookBook logCookBook : mRecipesInCookBooksMap.keySet()) { 
       for (Recipe logRecipe : mRecipesInCookBooksMap.get(logCookBook)) { 
        Log.e("R inside C", "CookBook " + logCookBook.getTitle() + " containts Recipe: " + logRecipe.getTitle()); 
       } 
      } 

      // attaches listener so that fragment displaying cookbooks receives arraylist containing cookbooks 
      if (mRecipesInCookBooksMap != null && mRecipesUpdateListener != null) { 
       mRecipesUpdateListener.onMapChanged((HashMap<CookBook, ArrayList<Recipe>>) mRecipesInCookBooksMap); 
      } 
     } 

     @Override 
     public void onCancelled(DatabaseError databaseError) { 

     } 
    }); 

    mDatabaseCookBooksKeyUploadsInUserBooks.addListenerForSingleValueEvent(new ValueEventListener() { 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      mCurrentUserCookBookKeyTitleMap = new HashMap<>(); 

      for (DataSnapshot snapshot : dataSnapshot.getChildren()) { 
       String key1 = snapshot.getKey(); 
       String title1 = snapshot.getValue(String.class); 

       mCurrentUserCookBookKeyTitleMap.put(key1, title1); 
      } 
      Log.e("CurrentUserCookBook", "Updated" + mCurrentUserCookBookKeyTitleMap.keySet()); 
     } 

     @Override 
     public void onCancelled(DatabaseError databaseError) { 

     } 
    }); 

    if (staticIntFromGeneralUploader == GeneralDataManager.RECIPE_UPDATES_LISTENER) { 
     mDatabaseRecipesUploadsBelowUser.addValueEventListener(recipeUpdatesListener); 

    } else if (staticIntFromGeneralUploader == GeneralDataManager.COOKBOOK_UPDATES_LISTENER) { 
     mDatabaseCookBooksKeyUploadsInUserBooks.addValueEventListener(cookBookKeysInUserBooksUpdatesListener); 

    } else if (staticIntFromGeneralUploader == GeneralDataManager.RECIPE_IN_COOKBOOK_UPDATES_LISTENER) { 
     mDatabaseCookBooksUploads.addValueEventListener(cookBookDatabaseListener); 

    } else if (staticIntFromGeneralUploader == GeneralDataManager.ATTACH_ALL_LISTENERS) {

     mDatabaseCookBooksKeyUploadsInUserBooks.addValueEventListener(cookBookKeysInUserBooksUpdatesListener); 
     mDatabaseCookBooksUploads.addValueEventListener(cookBookDatabaseListener); 
    } 

} 

partie MainActivity:

@Override 
protected void onStart() { 
    super.onStart(); 

    // new ImageLoadTask(imageUrl, mProfilePicture).execute(); 
    //Referring to the name of the User who has logged in currently and adding a valueChangeListener 
    myFirebaseRef.child(mUid).child("name").addValueEventListener(new ValueEventListener() {

     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      //Inside onDataChange we can get the data as an Object from the dataSnapshot 
      //getValue returns an Object. We can specify the type by passing the type expected as a parameter 
      String data = dataSnapshot.getValue(String.class); 

      GeneralDataManager.getInstance().attachListeners(GeneralDataManager.ATTACH_ALL_LISTENERS); 
     } 

     //onCancelled is called in case of any error 
     @Override 
     public void onCancelled(FirebaseError firebaseError) { 
      Toast.makeText(getApplicationContext(), "" + firebaseError.getMessage(), Toast.LENGTH_LONG).show(); 
      mAuth.signOut(); 
     } 
    });

Answer 1

je regardais plus profondément dans le problème et a trouvé la solution ce matin. C'est assez facile et je ne sais pas pourquoi je ne l'ai pas fait plus tôt.

Le problème résidait dans les règles.

Ce sont de vieilles règles:

{ 
    "rules": { 
    "recipes-309da": { 
     "cookbooks": { 
     ".read": "auth != null", 
      ".write": "auth != null", 
    }, 

    "recipes": { 
     ".read": "auth != null", 
      ".write": "auth != null", 
    }, 

    "users": { 
     "$uid": { 
      ".read": "auth != null", 
       ".write": "auth != null", 
     } 
    } 
    } 
    } 
} 

méthode I utilisé pour créer l'utilisateur était:

mRef.child("users").child(userId).setValue(user); 

Le résultat était évident - l'accès à/utilisateurs est limité aux utilisateurs, donc aucun utilisateur pourrait efficacement se connecter à la base de données ...

Je l'ai changé et maintenant il fonctionne parfaitement bien. Ci-dessous, je mets du nouveau code mis à jour. Un grand merci pour toute l'aide que vous m'avez fournie.

{ 
    "rules": { 
     "users": { 
       "$uid": { 
        ".read": true, 
          ".write": true, 

        "books": { 
           ".read": "auth != null", 
         ".write": "auth != null", 
       } 
      } 
     }, 

     "recipes": { 
      "$uid": { 
      ".read": "auth != null", 
       ".write": "auth != null", 
      } 
     }, 

       "cookbooks": { 
      ".read": "auth != null", 
      ".write": "auth != null", 
     } 
    } 
}
