我是laravel的新手，尝试创建一个搜索函数，但是我遇到了一个问题，代码返回一个空白页&它应该返回一个带有结果的表

这是BookSearchController

<?php

namespace App\Http\Controllers;
use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use DB;
use App\Book_Search;

class BookSearchController extends Controller
{
   public function searchForm(){
        return view('book-search');
   }
   public function searchbook(Request $request){
        $reader = new Book_Search;
        $reader->searchbooks($request);
   }
}

控制器应负责将数据返回给客户端

更改模型以从数据库返回结果集：

public function searchbooks(Request $request){

  $query = $request->get('query');
  $Books = DB::table('bookuser')->Join('users', 'bookuser.userID', '=','users.id')->Join('book', 'bookuser.bookID','=','book.ID')->select('Firstname','picture','price','availabilty','name')->where('name','like','%'. $query. '%')->get();

    return $Books;

}

和您的控制器：

public function searchbook(Request $request){
    $reader = new Book_Search;
    $Books = $reader->searchbooks($request);
    $query = $request->query;

    return view('book_search', compact('Books', 'query'));
}
