laravel5.3中文件上传期间的内部服务器错误 [英] Internal Server error during file uploading in laravel5.3

问题描述

我正在尝试在laravel中上传文件.但是每次我按下提交按钮时，都会在控制台中显示内部服务器错误.我已经用get请求检查了死记硬背，以检查控制器功能是否正常运行并且工作正常.可以说出什么问题吗? 这是我的代码示例

I am trying to upload a file in laravel.But every time i hit the submit button it gives me the internal server error in the console. I have checked the rote with a get request to check if the controller function is working properly and it works fine. Can any say what is the problem? here is my code samples

路线代码

Route::post('/storefile','PublicationController@storeFile');

控制器

public function storeFile(Request $request){
        if($request->ajax()){
            echo "got";
        }
        else echo "not ajax";
    }

                    }

推荐答案

尝试替换此

var file_data = $('#paper').prop('files')[0];

以此

var file_data = $('#paper').files[0];
