Firebase：为什么我的 Firestore 出现 [cloud_firestore/permission-denied]

Question

我知道有很多类似的帖子，但我仍然无法为我的问题找到自己的答案。由于我想在不按下按钮的情况下从 firebase 获取数据并且可以直接从中获取数据，因此我使用 StreamBuilder 进行编码，但仍然出现此错误。这是我的 Firestore 数据库还是实时数据库权限有问题？

下面是我的代码：

import 'dart:async';

import 'package:cloud_firestore/cloud_firestore.dart';
import 'package:firebase_core/firebase_core.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter/rendering.dart';
import 'package:profile_staff/edit_profile_page.dart';
import 'package:profile_staff/profile_widget.dart';
import 'package:profile_staff/user.dart';
import 'package:profile_staff/user_preferences.dart';

class ProfilePage extends StatefulWidget {
  const ProfilePage({Key? key}) : super(key: key);

  @override
  _ProfilePageState createState() => _ProfilePageState();
}

class _ProfilePageState extends State<ProfilePage> {
  final Stream<QuerySnapshot> users =
      FirebaseFirestore.instance.collection('users').snapshots();
  TextEditingController _controller = TextEditingController();

  void initState() {
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    final user = UserPreferences.myUser;

    return Scaffold(
      appBar: AppBar(
        leading: new IconButton(
            onPressed: () {}, icon: new Icon(Icons.arrow_back_ios_sharp)),
        title: Center(
          child: Text(
            'My Profile',
            style: TextStyle(color: Colors.white),
          ),
        ),
        actions: [
          IconButton(
              onPressed: () {
                Navigator.of(context).push(
                  MaterialPageRoute(builder: (context) => EditProfilePage()),
                );
              },
              icon: new Icon(Icons.create_outlined))
        ],
        backgroundColor: Colors.green,
        shadowColor: Colors.white,
        elevation: 3,
      ),
      body: Padding(
        padding: const EdgeInsets.all(20.0),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,
          children: [
            Text(
              'Read Data',
              style: TextStyle(fontSize: 20, fontWeight: FontWeight.w600),
            ),
            Container(
                height: 250,
                padding: const EdgeInsets.symmetric(vertical: 20),
                child: StreamBuilder<QuerySnapshot>(
                  stream: users,
                  builder: (
                    BuildContext context,
                    AsyncSnapshot<QuerySnapshot> snapshot,
                  ) {
                    // if (!snapshot.hasData) {
                    //   return Text('error404');
                    // }
                    
                    if (snapshot.connectionState == ConnectionState.waiting) {
                      return Text('Loading');
                    }

                    final data = snapshot.requireData;

                    return ListView.builder(
                      itemCount: data.size,
                      itemBuilder: (context, index) {
                        return Text(
                            'My name is ${data.docs[index]['name']} and I am ${data.docs[index]['age']}');
                      },
                    );
                  },
                ))
          ],
        ),
       
}
