Laravel Excel：错误资源解释为文档但使用 MIME 传输

如何解决Laravel Excel：错误资源解释为文档但使用 MIME 传输

用于导出数据的 Laravel Excel 将下载仅包含 excel 表格中的标题的空数据！ 我只想使用 excel 从我的搜索中导出过滤后的数据，但它会下载仅包含标题的空 excel 表格!!请谁能告诉我我的错误在哪里！

DealerExportSearch.php

class DealersSearchExport implements FromCollection,WithHeadings,ShouldAutoSize,WithEvents
{
    use Exportable;

    protected $name;
    protected $email;
    protected $mobile_no;
    protected $city;

    public function __construct( $name,$email,$mobile_no,$city)
    {
        $this->name         = $name;
        $this->email        = $email;
        $this->mobile_no    = $mobile_no;
        $this->city         = $city;
    }
     
    //function select data from database
    public function collection()
    {
        return Dealer::select()->where('name',$this->name)
                                ->where('email',$this->email)
                                ->where('mobile_no',$this->mobile_no)
                                ->where('city','=',$this->city) //i tried using the above and this also same result
                                ->get();
    }
    
    public function registerEvents(): array
    {
        return [
            AfterSheet::class    => function (AfterSheet $event) {
                $cellRange = 'A1:W1'; // All headers
                $event->sheet->getDelegate()->getStyle($cellRange)->getFont()->setSize(12);
            },];
    }

    //function header in excel
    public function headings(): array
    {
        return [
             'No','name','email','mobile_no','shop_name','city','address'
        ];
    }
}

我的控制器

public function index(Request $request)

{
 $method = $request->method();
        if ($request->isMethod('get')) {

            $name       = $request->name;
            $email      = $request->email;
            $city       = $request->city;
            $mobile_no  = $request->mobile_no;

            if ($request->has('search')) {
                $dealers = Dealer::where('name','LIKE','%'.$name.'%')
                            ->where('email','%'.$email.'%')
                            ->where('mobile_no','%'.$mobile_no.'%')
                           ->where('city','%'.$city.'%')
                            ->paginate(5);
                return view('dealer.index',compact('dealers'));
            }
            elseif ($request->has('exportSearchExcel')) {
                return Excel::download(new DealersSearchExport($name ?? '',$email ?? '',$mobile_no ?? '',$city ?? ''),'DealersSearchExcel-reports.xlsx');
            }
            else{
           $dealers = Dealer::orderBy('id','DESC')->paginate(5);
            return view('dealer.index',compact('dealers'));
            }
        }
    }

刀片

<form action="{{ route('dealer.index') }}" method="GET"  enctype="multipart/form-data">
        @csrf
        <div class="form-group row">
            <div class="col-sm-3">
                <label for="name">Name: </label>
                <input class="form-control" name="name" value="{{ request()->input('name') }}" type="text" placeholder="The Dealer Name">
            </div>
         .....................................................................
            </div>
            <div class="col-md-12 pt-3 text-right">
                <button type="submit" name="search" class="btn btn-primary"><i class="fa fa-fw fa-search"></i> Search</button>
                <button type="submit" name="exportSearchExcel" class="btn btn-secondary text-light"><i class="fa fa-download"></i> Export Excel  </button>                
            </div>
        </div>

我的控制台中没有显示任何错误，每当我按下导出按钮时，它都会返回此错误并下载一个空的 xslx。

资源被解释为 Document 但使用 MIME 类型 application/vnd.openxmlformats-officedocument.spreadsheetml.sheet 传输：“http://127.0.0.1:8000/dealer?_token=TTlpqFNn4hr5rwI1jSlt0d4mbtww2moO8i1WWjfn=&nameex=& /p>

解决方法

更新

我通过将我在 DealerExportSearch.php 中的查询更改为与我在 controller 中的查询相同的查询来解决此问题

DealerExportSearch.php

class DealersSearchExport implements FromCollection,WithHeadings,ShouldAutoSize,WithEvents,WithMapping
{
//the above codes not changed till the collection function

    //function select data from database
    public function Collection()
    {
        return Dealer::where('name','LIKE','%'.$this->name.'%')
                            ->where('email','%'.$this->email.'%')
                            ->where('mobile_no','%'.$this->mobile_no.'%')
                           ->where('city','%'.$this->city.'%')
                            ->get();

    }

 public function map($row): array{
           $fields = [
              $row->id,$row->name,$row->gender,$row->date_of_birth,$row->email,$row->mobile_no,$row->shop_name,$row->city,$row->address,];
        return $fields;
    }


///below codes not changed .....
