Laravel如何从数据库下载txt文件

Question

我正在研究laravel mini项目，我有几个小问题，但是这个问题很棘手，我检查了所有可能的解决方案，没有任何效果。 当我单击下载时，下载过程开始，但是随后我在失败-服务器问题中收到消息。

我想下载以name-last_name.txt格式命名的文件，以防有两个人具有相同的名字name-last_name / 2.txt

如果您可以与我分享任何知识是正确的过程，我将不胜感激

控制器

<?php
namespace App\Http\Controllers;
use Illuminate\Http\Request;
use Storage;
use App\Client;

class FormsController extends Controller
{
/**
 * Display a listing of the resource.
 *
 * @return \Illuminate\Http\Response
 */
public function index()
{
    //
    $clients = Client::all();
    return view('/index')->with('clients', $clients);
}

/**
 * Show the form for creating a new resource.
 *
 * @return \Illuminate\Http\Response
 */
public function create()
{
    //
    return view ('create');

}

/**
 * Store a newly created resource in storage.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function store(Request $request)
{
    //
    $this->validate($request, [
        'name' => 'required',
        'last_name' => 'required',
        'phone'=> 'required',
        'agree'=> 'required'
  ]);

    $client = new Client;
    $client->name = $request->input('name');
    $client->last_name = $request->input('last_name');
    $client->phone = $request->input('phone');
    $client->call_time = $request->input('call_time');
    $client->agree = $request->input('agree');
    $client->save();
    return redirect('/')->with('success', 'Klient vytvořen');
}

/**
 * Display the specified resource.
 *
 * @param  int  $id
 * @return \Illuminate\Http\Response
 */
public function show($id)
{
    //
    $client = Client::find($id);
    return view ('show')->with('client', $client);
}

public function download(){

    $client = Client::find($id);
    return response()->download($pathToFile);


}
