Question

我开始试用Firebase和Firestore并遇到问题。每当我设置我的规则并尝试查询文档时，我都会收到一个权限被拒绝的错误，但我没有看到这一点，为什么它被拒绝...

以下是我的规则：

service cloud.firestore {
   match /databases/{database}/documents {
      match /users/{user} {
        allow write: if request.auth.uid == resource.data.uid;
        allow read: if request.auth.uid != null;
        allow create: if request.auth.uid != null;
      }

   function userMightRead() {
       return (
       resource.data.viewers[request.auth.uid] != null || 
       resource.data.participants[request.auth.uid] != null || 
       request.auth.uid == resource.data.owner
     );
   }

   function userMightWrite() {
       return (
          resource.data.participants[request.auth.uid] != null || 
          request.auth.uid == resource.data.owner
       );
   }

   match /projects/{project} {
     allow create: if request.auth.uid != null;
     allow read: if userMightRead();
     allow write: if userMightWrite();
   }
  }
}

我在JS中的查询：

db.collection('projects')
    .where('viewer.' + this.user.uid, '==', true)
    .onSnapshot(snapshot => {
        let projects = [];
        snapshot.forEach(projectDoc => {
            projects.push({
                tasks: [],
                uid: projectDoc.id,
                ...projectDoc.data(),
                ref: projectDoc,
            });
        });
        this.projects.viewer = projects;

        this.loaded = true;
    }, (error) => {
        console.error("Couldn't fetch 'viewer' Projects!", error);
        alert(error.message);
    });

“项目”集合中的当前数据：

name: 'StatisticTool',
owner: '4UJFZOgQExUlqpYAToScWEh2GsA3'
participants: {
    4UJFZOgQExUlqpYAToScWEh2GsA3: true
},
viewers: {
    4UJFZOgQExUlqpYAToScWEh2GsA3: true
},

编辑：尝试访问文档的用户具有UID：4UJFZOgQExUlqpYAToScWEh2GsA3

查询时拒绝Firestore权限
