使用Anonymous Auth,Firebase突然停止工作

标签: android firebase firebase-storage

我为我的应用设置了firebase存储空间,并在应用和firebase控制台上添加了匿名身份验证代码。

它起初工作,但我不知道为什么它停止工作,说用户没有访问对象的权限

匿名身份验证设置正确,我确实看到它正常工作,代码几乎就像Google Firebase文档

logcat的:

  

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

...当我从firebase请求该项目时

  

E / StorageUtil:获取令牌java.util.concurrent.ExecutionException时出错:com.google.firebase.FirebaseException:发生了内部错误。 [遇到内部错误。]   I / DpmTcmClient:RegisterTcmMonitor   from:com.android.okhttp.TcmIdleTimerMonitor W / NetworkRequest:no auth   请求的标记E / StorageException:发生了StorageException。   用户无权访问此对象。   代码:-13021 HttpResult:403

有人可以帮忙吗?

声明变量

private FirebaseAuth mAuth;
private FirebaseAuth.AuthStateListener mAuthListener;

on OnCreate方法

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());
    }

我也使用标准安全规则:

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

答案 0 :(得分:4)

正如Benjamin Wulfe暗示的那样,我在手机上删除了应用程序的数据并且它有效,这意味着手机上存储了某种令牌数据,并且Anonymous Auth获得了旧的会话数据。

所以我在signInAnonymously

之前添加了一个注销代码
mAuth.signOut();

并完成了!

感谢大家的帮助!

编辑:我发现了另一种方法,它比退出并再次出现更好(导致firebase控制台上数百名未使用的匿名用户,而且由于该应用尚未投入生产,将有数百万)。 / p>

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。

答案 1 :(得分:3)

消息“W / NetworkRequest:没有请求的身份验证令牌”是调试此问题的关键。

此日志消息表示Firebase存储未在当前上下文中看到任何登录。这包括匿名登录。这意味着没有授权传递给后端,并且允许这样做的唯一方法是将规则设置为完全开放(公共访问),这是不推荐的(见下文)。

 //this sets completely open access to your data
 allow read, write;

我会检查您登录的代码,并确保在任何存储操作完成之前成功完成。 如果您确定您的身份验证代码是正确的,请尝试resetting data on the device,这样就不会有保存的状态来搞乱应用程序的授权信息。

答案 2 :(得分:0)

您可能需要在firebase控制台中检查 RULES 的存储空间。默认情况下,它仅设置为仅允许经过身份验证的用户 像这样

  allow read, write: if request.auth != null;

有时它与firebase数据库断开连接,所以通过firebase辅助工具在android studio中使用firebase身份验证连接你的应用程序。
