无法在 AngularFire 0.9.0 中使用新的密码身份验证方法? [英] Can't get new password authentication methods to work in AngularFire 0.9.0?

问题描述

我正在尝试在 Angular Fire 0.9.0 中使用新的身份验证方法，但我一定是做错了什么.

I'm trying to use the new authentication methods in Angular Fire 0.9.0 but I must be doing something wrong.

我正在运行 1.3.2 的 Angular、2.0.4 的 Firebase 和 0.9.0 的 Angular Fire.

I'm running 1.3.2 of Angular, 2.0.4 of Firebase and 0.9.0 of Angular Fire.

我从 html 中的 ng-click 调用登录功能.

I call the login function from an ng-click in my html.

这是我的js:

var app = angular.module("sampleApp", ["firebase"]);

app.controller('mainCtrl', function ($scope, $firebaseAuth) {

var ref = new Firebase('https://XXXX.xxx');

$scope.auth = $firebaseAuth(ref);

$scope.login = function() {
    $scope.num = 'loggin in';
    $scope.auth.$authWithPassword({
        email: '[e-mail]',
        password: 'yyyyy'
    }, function(err, authData) {
        if (err) {
            console.log(err);
            $scope.num = err;
        } else {
            console.log(authData);
        }
    });
};

我在控制台中没有看到任何内容，也没有收到任何错误.所以我不知道如何调试我做错了什么.

I don't see anything in the console and I don't get any errors. So I can't figure out how to debug what I am doing wrong.

当我将 $scope.auth 登录到控制台时，它会显示 $authWithPassword 方法.我就是无法让它工作.

When I log $scope.auth to the console, it shows the $authWithPassword method. I just can't get it to work.

任何帮助将不胜感激.

推荐答案

您遇到的问题是 AngularFire API 与用于身份验证方法的常规 Firebase API 略有不同.虽然 Firebase SDK 将回调作为 authWithPassword() 的第二个参数，但 AngularFire API 会返回 $authWithPassword() 的承诺.不同的原因是承诺是 Angular 中非常常见的习惯用法，我们希望提供一个人们已经熟悉的 API.因此，您的代码应如下所示:

The problem you are running into is that the AngularFire API is slightly different than the regular Firebase API for the authentication methods. While the Firebase SDK takes a callback as the second argument for authWithPassword(), the AngularFire API returns a promise for $authWithPassword(). The reason for the difference is that promises are a very common idiom in Angular and we wanted to provide an API that people are already familiar with. So, your code should look like this:

var app = angular.module("sampleApp", ["firebase"]);

app.controller('mainCtrl', function ($scope, $firebaseAuth) {
  var ref = new Firebase('https://XXXX.xxx');

  $scope.auth = $firebaseAuth(ref);

  $scope.login = function() {
    $scope.num = 'logging in';
    $scope.auth.$authWithPassword({
      email: '[e-mail]',
      password: 'yyyyy'
    }).then(function(authData) {
      console.log(authData);
    }).catch(function(error) {
      console.log(err);
      $scope.num = err;
    });
  };
});
