跨域图片上传 Angular+laravel

Question

我一直在为在服务器上上传图片而苦恼。我在前端使用 ngFileUpload。但我总是得到

"Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource"

Angular 文件上传代码：

 var uploadFile = function (file) {
      if (file) {

            if (!file.$error) {
              Upload.upload({
                  url: baseUrl+'upload',
                  file: file


              }).progress(function (evt) {
                  var progressPercentage = parseInt(100.0 * evt.loaded / evt.total);
                  //console.log(evt.total);
              }).success(function (data, status, headers, config) {
                  $timeout(function() {

                    console.log(data);
                    console.log(status);
                      if(status==200)
                        {

                          logo_path = data.logo_path;

                        }

                  });
              });
            }

      }
  };

在 Laravel 我已经像这样配置了 CORS：

public function handle($request, Closure $next)
{
    header("Access-Control-Allow-Origin: http://localhost:8001/");

    // ALLOW OPTIONS METHOD
    $headers = [
        'Access-Control-Allow-Methods'=> 'POST, GET, OPTIONS, PUT, DELETE',
        'Access-Control-Allow-Headers'=> 'Content-Type, X-Auth-Token, Origin'
    ];
    if($request->getMethod() == "OPTIONS") {
        // The client-side application can set only headers allowed in Access-Control-Allow-Headers
        return Response::make('OK', 200, $headers);
    }

    $response = $next($request);
    foreach($headers as $key => $value)
        $response->header($key, $value);
    return $response;
}

普通跨域POST 请求工作正常。即 $http.post()。我在 angular 上尝试了 headers 的许多不同变体，但 none 有帮助。还显示 OPTIONS 请求 returns 200 OK 但仍然显示飞行前响应失败消息。谁能帮我进一步调试这个问题？

尝试添加：

header('Access-Control-Allow-Origin: *'); 
header('Access-Control-Allow-Headers: Origin, Content-Type'); 
header('Access-Control-Allow-Methods: POST, GET, OPTIONS, PUT, DELETE');

在 bootstrap/app.php 您还可以在此处插入您可能需要进行访问控制的任何其他 header。
