我使用的是 Laravel 5.8，我想使用 LaravelExcel 从视图中下载数据。这是我的导出类：

namespace App\Exports;

use App\Member\Student;
use Illuminate\Contracts\View\View;
use Maatwebsite\Excel\Concerns\FromView;
use Maatwebsite\Excel\Facades\Excel;

class StudentExportView implements FromView
{
    /**
    * @return \Illuminate\Support\Collection
    */
    public function view(): View
    {
        return view('admin.students.custom',[
           'students' => Student::take(1)->get(),'customs' => Student::take(1)->get(),]);
    }
}

这里是下载csv的控制器方法：

public function export_view()
    {
        return Excel::download(new StudentExportView,'studentlist.csv');
    }

这里是调用这个方法的路由：

Route::get('export_view','StudentAdminController@export_view')->name('students.export_view');

但问题是，下载的内容是这样的：

如您所见，标题已损坏，正文似乎是空的。

那么如何解决这个问题？
