AngularJs 服务、文件上传、Laravel

我在处理 XHR 请求时遇到问题，由于某种原因我的服务器未收到我的文件：

这是我的角度服务更新算法：

var update = function(id, name, file) {                   

    var formData = new FormData();

    formData.append('name', name);
    formData.append('img', file);  

    return $http({
        method              : 'PUT',
        url                 : '/albums/' + id,
        data                : formData,
        headers             : {'Content-Type': undefined},
        transformRequest    : angular.identity
    });

};

在我的 laravel 控制器上我只有：

public function update($id) {

    return Response::json(Input::hasFile('img'));

}

该文件明明在那里，为什么我无法在后端检索它？

这是我的请求信息：

我发现了错误！显然我无法使用 PUT 方法发送文件，我将方法更改为 POST 并且它有效。在服务和 laravel 路线中

var update = function(id, name, file) {                   

    var formData = new FormData();

    formData.append('name', name);
    formData.append('img', file);  

    return $http({
        method              : 'PUT',
        url                 : '/albums/' + id,
        data                : formData,
        headers             : {'Content-Type': undefined},
        transformRequest    : angular.identity
    });

};
