Firebase RealtimeDatabase现在不工作？
现在，Firebase RealtimeDatabase“写入”正在工作。
这是Firebase示例代码。
FirebaseDatabase database = FirebaseDatabase.getInstance(); DatabaseReference myRef = database.getReference("message"); myRef.setValue("Hello, World!"); myRef.addValueEventListener(new ValueEventListener() { @Override public void onDataChange(DataSnapshot dataSnapshot) { // This method is called once with the initial value and again // whenever data at this location is updated. String value = dataSnapshot.getValue(String.class); Log.d(TAG, "Value is: " + value); } @Override public void onCancelled(DatabaseError error) { // Failed to read value Log.w(TAG, "Failed to read value.", error.toException()); } }); ValueEventListener的onDataChange ，但是我无法在Firebase控制台的实时数据库中find写入的数据。
另外，以前做的使用实时数据库的应用程序今天不行。
这是一个firebase的错误？ 我现在能做什么？
PS：这是日志消息。

尝试把OnComplete Listener，它被称为？
myRef.setValue("Hello, World!", new DatabaseReference.CompletionListener() { @Override public void onComplete(DatabaseError databaseError, DatabaseReference databaseReference) { if (databaseError != null) { Log.d("saving","Data could not be saved " + databaseError.getMessage()); } else { Log.d("saving","Data saved successfully."); } } }).addOnFailureListener(new OnFailureListener() { @Override public void onFailure(@NonNull Exception e) { Log.e("saving","Saving failed: " + e.getMessage()); } });
原因是我们公司的防火墙。 但我不知道为什么onDataChangecallback函数被调用。 我认为应该调用onCancelledcallback函数。
无论如何，我修改了防火墙规则，现在运行良好。
