我正在尝试使用Android中的Firebase存储上传文件。但是我收到以下异常：

我的Java代码：

File f= new File(filePath.getPath());
mStorageRef = FirebaseStorage.getInstance().getReference();
StorageReference userReference = mStorageRef.child(mAuth.getUid());
StorageReference fileReference = userReference.child(f.getName());               
fileReference.putFile(filePath)

我在Firebase中的安全规则：

  service firebase.storage {
  match /b/{bucket}/o {
    match /{userId} {      
      allow read,write: if request.auth.uid==userId;
     }
   }
  }

答案 0 :(得分：1)

当我将安全规则更改为时，该问题已解决：

import pandas as pd

df = pd.DataFrame({'A': [2, 3, 4], 'B': [5, 7, 9], 'C':[10, 11, 12]})

df['A'] = df ['A']*3
df['B'] = df ['B']*2

df.to_excel('output.xlsx')

}
