错误:文件格式或文件扩展名无效。验证文件未损坏

tok*_*000 0 php phpspreadsheet

我想在我的项目中使用 PHPSpreadsheet 库将数据导出到导出的文件中,但是当我尝试打开文件时,此错误显示:excel 无法打开文件,因为文件格式或文件扩展名无效。验证文件未损坏

  • 注意:我在我的项目中使用 MVC,所以控制器中的代码如下:

           protected function Excel($view, $variables = [])
    {
      require_once PATH_LIBRARY_FOLDER.'PhpSpreadsheet\vendor\autoload.php';
      ob_start();
      // Note: make new Spreadsheet object
      $spreadsheet = new Spreadsheet();
      // Note: get current active sheet (frist sheet)
      $sheet = $spreadsheet->getActiveSheet();
      $sheet->setCellValue('A1', 'Hello World !');
    
      extract($variables);
      include($this->viewPath.$view.'.php');
      // Note: set the header to define it is excel file
      header("Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet");
      // Note: set the header to define excel file name
      header("Content-Disposition: attachment;filename=\"filename.xlsx\"");
      header("Cache-Control: max-age=0");
    
      // Note: create IOFactory object
      $writer = IOFactory::createWriter($spreadsheet, 'xlsx');
      ob_get_clean();
    
      $writer->save('php:://output');
      exit();
    }

当我以文本形式打开文件时,我发现了这个错误:

致命错误:未捕获的 PhpOffice\PhpSpreadsheet\Writer\Exception:无法打开 php:://output 进行写入。在 C:\xampp\htdocs\GL_App\Library\PhpSpreadsheet\vendor\phpoffice\phpspreadsheet\src\PhpSpreadsheet\Writer\Xlsx.php:218

我有同样的问题,我的解决方案在这里。只需将代码放在下面:

ob_end_clean();

代码:

        ob_end_clean();
        header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
        header('Content-Disposition: attachment;filename="'. $filename );
        header('Cache-Control: max-age=0');

        $writer->save('php://output'); // download file
