Question

我是firebase的新手，我正试图通过.then()

上的firebase.auth().createUserWithEmailAndPassword(email, password)将用户对象（用户电子邮件）保存到数据库

当我尝试这样做时会抛出错误：

FIREBASE警告：设置为/ users / -KlMikr6xZnfYC6dFJ6L失败：permission_denied

基本上说我没有权限将用户数据设置为用户节点。

我知道该函数何时起作用，因为当我将安全性写入规则设置为true时，会在数据库中创建userobj。

不确定我做错了什么。

controller.js

angular.module('app')
  .controller('appCtrl', function($scope){

    //empty user object to store info
    $scope.user = {};

    //empty object to accept user password
    $scope.password = {};

    // add login event
    $scope.signUp = function(){
      const email = $scope.user.email;
      const password = $scope.password.setup;

      // create new firebase user
      firebase.auth().createUserWithEmailAndPassword(email, password)
        // add user object to database
        .then(function(){
          var userObj = $scope.user;
          console.log($scope.user);

          // set up database references
          let database = firebase.database();
          let ref = database.ref();
          let usersRef = ref.child('users');

          // push user object to database
          usersRef.push(userObj);

        })
        .catch(function(error) {
          // Handle Errors here.
          var errorCode = error.code;
          var errorMessage = error.message;
          console.log(errorCode);
          console.log(errorMessage);
        });   
    };

    firebase.auth().onAuthStateChanged(function(user) {
      if (user) {
        // User is signed in.
        console.log('user signed in');
        var uid = user.uid;
        console.log(uid);
      } else {
        // No user is signed in.
        console.log('user not signed in');
      }
    });

  })

Firebase数据库规则

"rules": {
  "users": {
    "$uid": {
        ".read": true,
        ".write": "(auth.uid === $uid)"
    }
  }
}

问题是您使用的是 .push（），它会使用新的UID创建子级。您应检索新创建的用户UID，并将对象分配给相关参考。

let uid = firebase.auth().currentUser.uid;
let usersRef = ref.child('users').child(uid);
usersRef.set(userObj);

Firebase数据未保存
