在使用Firestore权限(通过Expo)响应本机应用程序中-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();
    }
});

还有，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;
    }
  }
}

似乎无论如何，request.auth始终为null. 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 [Connection]:WebChannel 收到错误:{代码":403，消息":缺少或不足 权限.，"状态:" 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上使用最新的Firebase JS SDK遇到此问题时，我将其降级为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，您必须执行此操作才能使所有内容正常工作:

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

复制 https://gist.githubusercontent8.4/a4d /raw/85ac4cb3108d92163cb8f04fbdddcc88d4081aab/index.js

在您的node_modules/@firebase/webchannel-wrapper/dist/index.js

否则，您的收藏夹将一无所获.

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

希望这会有所帮助.
