AngularJs 服务、文件上传、Laravel

Question

我在处理 XHR 请求时遇到问题，由于某种原因我的服务器未接收我的文件:

这是我的 angular.service 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 Controller 上，我只有:

public function update($id) {

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

}

文件明明就在那里，为什么我无法在后端检索到它？

这是我的请求信息:

我发现错误了!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 路由中

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
    });

};
