扑来：i/flutter（8345）：[cloud_firestore/允许被拒绝]呼叫者无权执行指定的操作

Question

我想访问Firebase的数据以显示在我的应用程序中。我已经使用Firebase在此应用程序上工作了几天，但是今天我有一个错误说 我的代码：

StreamBuilder<QuerySnapshot>(
                    stream:
                        FirebaseFirestore.instance.collection('videos').snapshots(),
                    builder: (BuildContext context,
                        AsyncSnapshot<QuerySnapshot> snapshot) {
                      if (snapshot.hasError) {
                        return Text('Something went wrong!');
                      }
                      if (snapshot.connectionState == ConnectionState.waiting) {
                        return Center(child: CircularProgressIndicator());
                      }
                      return ListView(
                        shrinkWrap: true,
                        physics: ClampingScrollPhysics(),
                        children:
                            snapshot.data!.docs.map((DocumentSnapshot document) {
                          Map<String, dynamic> data =
                              document.data()! as Map<String, dynamic>;
                          return GestureDetector(
                            onTap: () {},
                            child: HomeDisplayScreen(
                              videoLink: data['videoLink'],
                              imageUrl: data['imageUrl'],
                              title: data['title'],
                              likes: data['likes'],
                            ),
                          );
                        }).toList(),
                      );
                    })

错误：

W/Firestore( 8345): (24.1.2) [Firestore]: Listen for Query(target=Query(videos order by __name__);limitType=LIMIT_TO_FIRST) failed: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}
W/Firestore( 8345): (24.1.2) [Firestore]: Listen for Query(target=Query(users/*****@gmail.com order by __name__);limitType=LIMIT_TO_FIRST) failed: Status{code=PERMISSION_DENIED, description=Missing or insufficient permissions., cause=null}
I/flutter ( 8345): [cloud_firestore/permission-denied] The caller does not have permission to execute the specified operation.

我还将安全规则更改为此

rules_version = '2';
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write : if true;
    }
  }
}

，我遇到了相同的错误

Answer 1

我不知道您是否已经解决了问题，但是您遇到的错误是因为您的Firestore规则，因此要将其修复到Firestore规则中并更改它们。

Answer 2

内部projectFolder/android/app/src/main/androidmanifest.xml尝试添加以下内容并重建您的应用程序：

 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
