firebase - Firebase Cloud Firestore无法正常工作

Question

我正在构建使用Cloud Firestore的应用程序。问题是Firestore无法正常工作。这是我正在使用的代码
达特

class Db{

  // collection reference
  static final CollectionReference _collectionReference = Firestore.instance.collection("codes");

  static Future addOrUpdateCode(String code , double lat , double long) async {
    return await _collectionReference.document(code).setData({
      'lat':lat,
      'long':long
    });
  }

}

我已经在pubspec.yaml中添加了这一行

cloud_firestore: ^0.13.7

我收到这些错误

在云控制台中启用了以下API

通过在Firebase中启用的电子邮件/密码注册
我正在使用这些规则

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

我相信足够的信息。感谢您的时间。

Firestore安全规则配置不正确。参见Get started with Cloud Firestore Security Rules。
既然您提到要实现Firebase身份验证，那么您将需要像它们提供的示例一样的东西:

// Allow read/write access on all documents to any user signed in to the application
service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth != null;
    }
  }
}

但是请注意，您可能还会想要通过自定义 token 进行多级管理。查看 Create Custom Tokens，您可能最终会得到类似规则的内容，该规则允许管理员访问所有内容，然后从此处缩小访问范围，例如:

service cloud.firestore {
  match /databases/{database}/documents {
    match /{document=**} {
      allow read, write: if request.auth.token.admin == true;
    }
    match /users/{userId} {
      allow read, write: if request.auth.uid == userId;
    }
  }
}
