弹出的 React Native 应用程序无法访问 Firestore 后端

Question

我在使用 expo 的 react-native 应用程序中通过 Firebase Javascript SDK 使用 Firestore，但是从 expo 弹出后，即使我的设备已连接到互联网，我也会收到此错误：

@firebase/firestore: Firestore (7.19.1): Could not reach Cloud Firestore backend. Backend didn't respond within 10 seconds.
This typically indicates that your device does not have a healthy Internet connection at the moment. The client will operate in offline mode until it is able to successfully connect to the backend.

我该如何解决这个问题，还是应该只使用 react-native-firebase 包？

Answer 1

我能够通过在我的 firebase config.js 底部添加这一行来解决这个问题：

export const firebase = Firebase.initializeApp(firebaseConfig);
firebase.firestore().settings({experimentalForceLongPolling: true}); // add this

现在 firestore 对我来说按预期工作
