如何删除firestore数据库中有子文档的文档？

const docRef = db.collection('collection').doc('document').collection('subcollection').doc('subdocument');

docRef.delete().then(() => {
  console.log("文档删除成功");
}).catch((error) => {
  console.error("删除文档时出错：", error);
});

doc_ref.delete()

docRef.delete().addOnSuccessListener(new OnSuccessListener<Void>() {
    @Override
    public void onSuccess(Void aVoid) {
        System.out.println("文档删除成功");
    }
}).addOnFailureListener(new OnFailureListener() {
    @Override
    public void onFailure(@NonNull Exception e) {
        System.err.println("删除文档时出错：" + e);
    }
});
