Question

我一直在尝试从 firestore 读取数据，但无法读取...

async authUser() {
    let token = this._tokman.getUserToken();
    await this._afa.signInWithCustomToken(token);
  }

从服务器获取令牌并将其传递给 firebase 以验证用户身份。然后调用firestore获取数据..

async data() {
    await this._afa.onAuthStateChanged(user => {
      if (user) {
        this._afs.collection('gps-data').doc(user.uid)
          .valueChanges()
          .subscribe(res => {
            console.log(res);
          }, err => {
            console.log(err);
          })
      }
    })
  }

但是从 firestore 得到这个错误。

FirebaseError: Missing or insufficient permissions.

Firestore 安全规则是

 service cloud.firestore {
  match /databases/{database}/documents {
    match /gps-data/{userid} {
        allow read: if request.auth.token.sub == userid;
    }
   
  }
}

还将 jwt 令牌添加到 http 标头。请指导我哪里做错了。

更新解决方法：更改 firebase 版本来自

"firebase": "^7.0 || ^8.0"

致

"firebase": "^8.0.2"

不改变安全规则

AngularFirestore 权限缺失或不足（Firebase 自定义令牌身份验证）
