如何处理 Firebase Web 中的 auth/argument-error？

Question

我正在使用 Firebase 开发一个网络项目，我需要处理登录页面上的所有身份验证错误。

为什么我无法得到 error.code 等于 'auth/argument-error'，就像我处理其他 'auth/something-error' 错误代码一样？

例如当我有一个登录表单并按下没有填写电子邮件和密码的按钮时，控制台中会抛出以下错误：

如何获取此错误对象并保存在变量中？

@Frank van Puffelen，请回答。

signin.js

vm.signIn = function() {
        vm.loading = true;
        return $q(function(resolve, reject) {
            firebaseAuth.$signInWithEmailAndPassword(vm.email, vm.password)
                .then(function(firebaseUser) {
                    console.log('[Firebase] User signed as', firebaseUser);
                    vm.loading = false;
                    resolve();
                    $state.go('main');

当电子邮件或密码未提供给 firebase 并且无法在 catch 块中处理时，就会发生这种情况。因为这是一个参数错误。下面是检查电子邮件和密码是否存在的代码，然后只调用 firebase.auth()

$scope.login = function(data){
    $scope.err = null;
    $scope.busy = true;
    if(!data || !data.email || !data.password){
        $timeout(function(){
            $scope.err = {
                code:'InvalidParms',
                message: "Please provide correct email."
            };
            $scope.busy = false;
        },0);
        return;
    }

    firebase.auth().signInWithEmailAndPassword(data.email,data.password).then(function(res){
        if(res){                                    
            $rootScope.user = res;
            if(res.emailVerified){
                $location.path('/');
            }else{
                $timeout(function(){
                    $scope.err = {
                        code:'EmailNotVerified',
                        message: "You email is not yet verified. Please verify your email. Click on resend verification mail if you haven't got a verification mail from us."
                    };
                },0);
            }
            //
        }
        $scope.busy = false;
    }).catch(function(err){
        $timeout(function(){
            console.log(err);
            $scope.busy = false;
        },0);

    });
