无法在 Laravel 中导出 Excel，找不到 404

如何解决无法在 Laravel 中导出 Excel，找不到 404

我在 Laravel 中导出 Excel 文件时遇到了一些问题。当我单击导出按钮时，页面显示“404 Not Found”。我试过 php artisan route:clear 或 php artisan route:cache 但它不起作用。

希望你能帮我解决问题。这是我的代码：

App\Teacher.php：

    <?php
    namespace App;
    use Illuminate\Database\Eloquent\Model;

    class Teacher extends Model {
        protected $guarded = [];
        protected $table = 'teachers';
    }

App\Exports\TeacherExport.php:

    <?php
    namespace App\Exports;

    use App\Teacher;
    use Maatwebsite\Excel\Concerns\FromCollection;
    use Maatwebsite\Excel\Concerns\WithHeadings;

    class TeacherExport implements FromCollection,WithHeadings {    
        public function headings():array {
            return [
                'id','name','email','created_at','updated_at'
            ];
        }
        /**
         * @return \Illuminate\Support\Collection
         */
        public function collection() {
            return Teacher::all();
        }
    }

App\Controllers\TeachersController.php:

    public function exportTeacherIntoExcel() {
        return Excel::download(new TeacherExport,'teacher.xlsx');
    }

web.php：

Route::get('/teacher/export-excel','TeachersController@exportTeacherIntoExcel');

资源\视图\教师\index.blade.php：

    @extends('home')
    @section('content')
        <div class="card mb-3">

解决方法

谢谢大家。我已经解决了我的问题。这里的问题是路线的顺序。在我的路线中，我像这样修复了它并且它有效。 web.php:

/**
 * Teacher
 */
Route::get('/teacher/export-excel','TeachersController@exportTeacherIntoExcel');
Route::get('/teacher','TeachersController@index');
Route::get('/teacher/create','TeachersController@create');
Route::post('/teacher','TeachersController@store');
Route::get('/teacher/{teacher}/edit','TeachersController@edit');
Route::patch('/teacher/{teacher}','TeachersController@update');
Route::get('/teacher/{teacher}','TeachersController@destroy');
