Question

我正在尝试在我的服务器上传图片，但是我的api没有获取该文件，并说“＆＃34;在null＆＃34;上调用成员函数getClientOriginalExtension（）”。我不知道问题出在哪里。这是我的代码。我没有得到如何验证它。请帮帮我。

角度代码

function upload(image)
        {
          vm.ngFlow.flow.opts.headers = {
                'X-Requested-With': 'XMLHttpRequest',
                'UID'    : '7798616828'
            };
            vm.ngFlow.flow.opts.query = {'ID':'203'};
            vm.ngFlow.flow.opts.testMethod = 'post';
            vm.ngFlow.flow.opts.uploadMethod = 'post';
            vm.ngFlow.flow.opts.target = 'http://{url}/contact/image/upload';

            vm.ngFlow.flow.upload();
        }

Laravel API

public function upload_image(Request $request){

        $photo = $request->file('file');
        $imagename = time().'.'.$photo->getClientOriginalExtension(); 

        $destinationPath_thumb = storage_path('images/contact/thumbnail_images');
        $thumb_img = Image::make($photo->getRealPath())->resize(100, 100);
        $thumb_img->save($destinationPath_thumb.'/'.$imagename,80);

        $destinationPath_medium = storage_path('images/contact/medium_images');
        $medium_img = Image::make($photo->getRealPath())->resize(500, 500);
        $medium_img->save($destinationPath_medium.'/'.$imagename,80);

        $destinationPath_original = storage_path('images/contact/original_images');
        $photo->move($destinationPath_original, $imagename);

        $user = \App\User::select(['inst_id'])->where('mobile','=',$request->header('UID'))->first();

        $update_img = \App\Contact::where([['id','=',$request->ID],['inst_id','=',$user->inst_id]])->update(['image'=>$imagename]);

        if($update_img)
          $response = response()->json(['data'=>[], 'error'=>0,  'error_msg'=>'', 'message'=>'Profile updated']);
        else
          $response = response()->json(['data'=>[], 'error'=>1,  'error_msg'=>'some went wrong', 'message'=>'Please try again']);

    return  $response;
  }
