我有一個excel文件,我想用php excel將文件轉換爲pdf。使用下面的代碼:將excel文件轉換爲pdf,使用phpexcel返回空文件
namespace frontend\controllers;
use PHPExcel;
use PHPExcel_IOFactory;
use PHPExcel_Settings;
use PHPExcel_Style_Alignment;
use yii\web\Controller;
class ExportsController extends Controller
{
public function actionIndex()
{
$inputFile = \Yii::getAlias('@frontend') . '/controllers/matrix.xls';
$inputFileType = PHPExcel_IOFactory::identify($inputFile);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objPHPExcel = $objReader->load($inputFile);
$objPHPExcel->setActiveSheetIndex(0);
$rendererLibrary = 'DomPDF';
$rendererLibraryPath = \Yii::getAlias('@frontend') . '/components/Classes/PHPExcel/Writer/PDF/' . $rendererLibrary;
$rendererLibraryPath .= '.php';
if (!PHPExcel_Settings::setPdfRenderer(
$rendererLibrary,
$rendererLibraryPath
)
) {
die(
'NOTICE: Please set the $rendererName and $rendererLibraryPath values' .
'<br />' .
'at the top of this script as appropriate for your directory structure'
);
}
header('Content-Type: application/pdf');
header('Content-Disposition: attachment;filename="01simple.pdf"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'PDF');
$objWriter->save('php://output');
}
}
當我評論的最後兩行代碼否則它會返回空的PDF文件,其拋出以下錯誤:net::ERR_INVALID_RESPONSE
。
你能幫我找到代碼的錯誤嗎?
仍然是一樣的錯誤 –
當我把$ objWriter = PHPExcel_IOFactory :: createWriter($ objPHPExcel,'PDF');在標題之前,它沒有給net :: ERR_INVALID_RESPONSE,但顯示另一個錯誤無法加載PDF渲染庫 –
使用required_once加載PDF庫 –
