在使用 firestore 权限的本机应用程序(通过 Expo)中 - request.auth 始终为 null [英] In react native app (through Expo) using firestore permissions - request.auth is always null

问题描述

这是我的代码:

firebase.auth().onAuthStateChanged((user) => {
    if (user) {
        console.log("We are authenticated now!");
        firebase.firestore().collection("users")
            .doc(firebase.auth().currentUser.uid).set({ name: "new name" });
    } else {
        loginWithFacebook();
    }
});

而且，这是我的许可规则:

And, here are my permission rules:

service cloud.firestore {
  match /databases/{database}/documents {
    match /users/{userId} {
      allow read, write: if request.auth != null;
    }
  }
}

好像不管怎样，request.auth 总是空的.我得到的错误:

It seems like no matter what, request.auth is always null. The error I get:

Firestore (4.8.0) 2017-12-20T04:18:27.321Z [连接]:WebChannel收到错误:{"code":403,"message":"缺失或不足权限.","status":"PERMISSION_DENIED"}

Firestore (4.8.0) 2017-12-20T04:18:27.321Z [Connection]: WebChannel received error: {"code":403,"message":"Missing or insufficient permissions.","status":"PERMISSION_DENIED"}

推荐答案

当我在 Expo 上遇到最新 Firebase JS SDK 的问题时，我降级到 Firebase SDK 4.6.2.

I downgraded to Firebase SDK 4.6.2 when I had this problem with latest Firebase JS SDK on Expo.

此外，您必须这样做才能使一切正常:

Also, you have to do this in order for everything to work:

在你的node_modules/@firebase/webchannel-wrapper/dist/index.js

没有它，您将一无所获.

Without this, you'll get nothing from your collections.
