Firebase使用匿名身份验证突然停止工作

Question

我已经为我的应用设置了Firebase存储，并在应用和Firebase控制台上添加了用于匿名身份验证的代码。

它起初起作用，但是我不知道为什么它停止起作用，说用户没有访问该对象的权限

匿名身份验证已正确设置，我确实看到它可以正常工作，代码几乎就像Google Firebase文档一样

日志猫：

D / FirebaseAuth：signInAnonymously：onComplete：true
D / FirebaseAuth：onAuthStateChanged：signed_in：（随机身份验证用户ID）

...当我从Firebase请求项目时

E / StorageUtil：获取令牌java.util.concurrent.ExecutionException时出错：com.google.firebase.FirebaseException：发生内部错误。[遇到内部错误。] I / DpmTcmClient：来自com.android.okhttp.TcmIdleTimerMonitor的RegisterTcmMonitor W / NetworkRequest：没有针对请求E / StorageException的身份验证令牌：发生StorageException。用户无权访问此对象。代码：-13021 Http结果：403

有人可以帮忙吗？

声明变量

private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;

在OnCreate方法上

mAuthListener = new FirebaseAuth.AuthStateListener() {
        @Override
        public void onAuthStateChanged(@NonNull FirebaseAuth firebaseAuth) {
            FirebaseUser user = firebaseAuth.getCurrentUser();
            if (user != null) {
                // User is signed in
                Log.d("FirebaseAuth", "onAuthStateChanged:signed_in:" + user.getUid());
            } else {
                // User is signed out
                Log.d("FirebaseAuth", "onAuthStateChanged:signed_out");
            }
            // ...
        }
    };
    mAuth.signInAnonymously()
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    Log.d("FirebaseAuth", "signInAnonymously:onComplete:" + task.isSuccessful());

                    // If sign in fails, display a message to the user. If sign in succeeds
                    // the auth state listener will be notified and logic to handle the
                    // signed in user can be handled in the listener.
                    if (!task.isSuccessful()) {
                        Log.w("FirebaseAuth", "signInAnonymously", task.getException());
                        Toast.makeText(SingleMemeEditor.this, "Authentication failed.",
                                Toast.LENGTH_SHORT).show();
                    }

                    // ...
                }
            });

以及从存储中获取的方法：

    Bitmap bmp;
    final Context lContext = context; //getting the MainActivity Context
    final String lFileName = fileName; //filename to download
    final String lCatPath = catPath; //internal categorization folder

    FirebaseStorage storage = FirebaseStorage.getInstance();
    // Create a storage reference from our app
    StorageReference storageRef = storage.getReferenceFromUrl(context.getResources().getString(R.string.firebase_bucket));
    // Create a reference with an initial file path and name
    StorageReference filesRef = storageRef.child("files/" + fileName);
    try
    {
        final File localFile = File.createTempFile("images", "jpg");

        filesRef.getFile(localFile).addOnSuccessListener(new OnSuccessListener<FileDownloadTask.TaskSnapshot>()
        {
            @Override
            public void onSuccess(FileDownloadTask.TaskSnapshot taskSnapshot)
            {
                // Local temp file has been created
                File file = new File(getDirectory(lContext)
                        + File.separator + lCatPath + File.separator + lFileName);
                try
                {
                    Boolean b = file.createNewFile();
                    if(b)
                    {
                        FileInputStream in = new FileInputStream(localFile);
                        FileOutputStream out = new FileOutputStream(file);

                        // Transfer bytes from in to out
                        byte[] buf = new byte[(int)localFile.length()];
                        int len;
                        while ((len = in.read(buf)) > 0) {
                            out.write(buf, 0, len);
                        }
                        in.close();
                        out.close();
                    }
                            Drawable.createFromPath(file.getPath())).getBitmap());
                }
                catch (IOException ex)
                {
                    // Handle any errors
                    Log.e("CopyingFromTemp", ex.getMessage());
                }

            }
        }).addOnFailureListener(new OnFailureListener()
        {
            @Override
            public void onFailure(@NonNull Exception ex)
            {
                // Handle any errors
                Log.e("FirebaseDownloadError", ex.getMessage());
            }
        });
    }
    catch(Exception ex)
    {
        Log.e("FirebaseDownloadError", ex.getMessage());
    }

我也使用标准的安全规则：

match /{allPaths=**} {
      allow read, write: if request.auth != null;
    }

Answer 1

正如本杰明·沃夫（Benjamin Wulfe）所暗示的那样，我删除了手机上的应用程序数据，并且该数据正常运行，这意味着某种令牌数据已存储在手机上，并且匿名身份验证正在获取旧的会话数据。

所以我在signInAnonymously之前添加了退出代码

mAuth.signOut();

并做了！

感谢大家的帮助！

编辑：我发现了另一种方法，该方法比注销然后再登录更好（这导致Firebase控制台上有数百个未使用的匿名用户，并且因为该应用程序尚未投入生产，因此将有数百万个）。

这就是我所做的：

if (mAuth.getCurrentUser() != null)
        {
            mAuth.getCurrentUser().reload();
        }
        else
        {
            mAuth.signInAnonymously()
                    .addOnCompleteListener(this, new OnCompleteListener<AuthResult>()
                    {
                        @Override
                        public void onComplete(@NonNull Task<AuthResult> task)
                        {
                            Log.d("FirebaseAuth", "signInAnonymously:onComplete:" + task.isSuccessful());

                            // If sign in fails, display a message to the user. If sign in succeeds
                            // the auth state listener will be notified and logic to handle the
                            // signed in user can be handled in the listener.
                            if (!task.isSuccessful())
                            {
                                Log.w("FirebaseAuth", "signInAnonymously", task.getException());
                                Toast.makeText(MainActivity.this, "Authentication failed.",
                                        Toast.LENGTH_SHORT).show();
                            }
                            // ...
                        }
                    });
        }

这只会重新加载当前经过身份验证的（匿名）用户。
