Firebase安全规则无法识别request.auth.token.name

我想使用用户的显示名称来应用安全规则。 我使用了signInAnonymously和updateProfile。

这是我的客户代码

var firebase = require('firebase/app')
require('firebase/auth')
require('firebase/firestore')

firebase.initializeApp(~~~)
firebase.auth().signInAnonymously().then(({user}) => {
  user.updateProfile({
    displayName: 'ABC',
  }).then(() => {
    // {..., uid: '~~~', displayName: 'ABC', photoURL: null}
    console.log(user.toJSON()) 

    var db = firebase.firestore()
    db.collection('HelloCollection').doc('WorldDoc').get()
      .then((doc) => { console.log('Success') })
      .then((err) => { console.log('Failed', err) })
  })
})

这是我的Firestore安全规则

service cloud.firestore {
  match /databases/{database}/documents {
    match /HelloCollection/{docId} {
      // allow read, create, update: if true; // This evaluated true.
      // This evaluated false.
      allow read, create, update: if request.auth.token.name == "ABC";
    }
  }
}

我期望“成功”, 但实际输出是

Failed FirebaseError: Missing or insufficient permissions.

我无法直接解决此问题,但通过使其通过UserID而不是User name进行身份验证来绕过该问题,如下所示:

request.resource.data.uid == request.auth.token.sub

请注意,也应更改查询HelloCollection,以便存储带有文本的用户ID。

这是一个工作示例..

match /stuff/{candy} {
  allow read, write: if request.auth.token.name == candy
}

@fre bern 是对的。您可以通过“request.auth.token.name”访问用户的显示名称..如果你不能让它工作.. mb sth你的代码有问题
