Angularjs上传图片

Question

我尝试使用angularjs创建上传功能。我在互联网上观看并阅读了一些教程。不幸的是，所有教程对我来说都太复杂了，因为我在这个领域还是新手。

<form ng-submit="upload(currentUser())">
    <div class="row">
        <div class="form-group">
            <div class="col-xs-2">

    <div class="row">

            </div>
            <div class="col-xs-5"></div>
        </div>
    </div>
    <br>
    <br>
</form>

＆＃13;

＆＃13;

＆＃13;

＆＃13;

＆＃13;

app.controller('postadCtrl', [
    '$scope',
    'auth',
    function($scope, auth) {

    	$scope.currentUser = auth.currentUser;

        $scope.posts = [];

        $scope.upload = function(user) {
            $scope.posts.push({
            	company_name: user,
                car_type: $scope.newCar,
                seaters: 5,
                price: $scope.newPrice,
                contact: 038880000,
                location: $scope.businessArea
            });
        };
    }
]);

那么我该如何以最简单的形式和解释来做到这一点？我的路由器和模块将如何？ 输出应该如下所示。
