【中文标题】生成和下载 excel 文件会生成 ERR_INVALID_RESPONSE【英文标题】:Generating and downloading an excel file generates a ERR_INVALID_RESPONSE 【发布时间】:2015-10-01 18:46:55 【问题描述】:这是我的代码:
public function downloadexcel($requestId)
$this->loadModel('MaterialsRequest');
$materialsRequests = $this->MaterialsRequest->find('all', array('conditions' => array('MaterialsRequest.request_id' => $requestId)));
date_default_timezone_set('Europe/London');
if (php_SAPI == 'cli')
die('This example should only be run from a Web Browser');
/** Include PHPExcel */
//require_once dirname(__FILE__) . '/../Classes/PHPExcel.php';
// Create new PHPExcel object
$objPHPExcel = new PHPExcel();
// Set document properties
$objPHPExcel->getProperties()->setCreator("mez")
->setLastModifiedBy("mez")
->setTitle("Supply Template")
->setSubject("Supply Template")
->setDescription("Supply Template , please fill and upload.")
->setKeywords("office 2007 openxml php")
->setCategory("Supply");
$objPHPExcel->getActiveSheet()->getColumnDimension('A')->setWidth(10);
$objPHPExcel->getActiveSheet()->getColumnDimension('B')->setWidth(40);
$objPHPExcel->getActiveSheet()->getColumnDimension('C')->setWidth(30);
$objPHPExcel->getActiveSheet()->getColumnDimension('D')->setWidth(30);
$objPHPExcel->getActiveSheet()->getStyle('A')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::HORIZONTAL_LEFT);
$objPHPExcel->getActiveSheet()->getStyle('B')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('C')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);
$objPHPExcel->getActiveSheet()->getStyle('D')->getAlignment()->setHorizontal(PHPExcel_Style_Alignment::VERTICAL_CENTER);
// Add some data
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A1', 'Material ID')
->setCellValue('B1', 'Material Name')
->setCellValue('C1', 'Quantity')
->setCellValue('D1', 'Your offer');
$index = 2;
foreach ($materialsRequests as $oneMaterialsRequests)
$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A' . $index, $oneMaterialsRequests['MaterialsRequest']['material_id'])
->setCellValue('B' . $index, $oneMaterialsRequests['Material']['name'])
->setCellValue('C' . $index, $oneMaterialsRequests['MaterialsRequest']['qty'])
->setCellValue('E' . $index, $oneMaterialsRequests['MaterialsRequest']['id']);
$index++;
/// Set sheet security
$MaterialsRequestsNo = count($materialsRequests);
$MaterialsRequestsNo+=1; //add count for header
$objPHPExcel->getActiveSheet()->getProtection()->setSheet(true);
$objPHPExcel->getActiveSheet()
->getStyle('D2:D' . $MaterialsRequestsNo)
->getProtection()->setLocked(
PHPExcel_Style_Protection::PROTECTION_UNPROTECTED
);
// Miscellaneous glyphs, UTF-8
// Rename worksheet
$objPHPExcel->getActiveSheet()->setTitle('Supply');
// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);
// Redirect output to a client’s web browser (Excel2007)
header('Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet');
header('Content-Disposition: attachment;filename="Supply.xlsx"');
header('Cache-Control: max-age=0');
// If you're serving to IE 9, then the following may be needed
header('Cache-Control: max-age=1');
// If you're serving to IE over SSL, then the following may be needed
header('Expires: Mon, 26 Jul 1997 05:00:00 GMT'); // Date in the past
header('Last-Modified: ' . gmdate('D, d M Y H:i:s') . ' GMT'); // always modified
header('Cache-Control: cache, must-revalidate');// HTTP/1.1
header('Pragma: public'); // HTTP/1.0
$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
$objWriter->save('php://output');
exit;
当我调用此函数时,我可以从在灯上运行的本地服务器获取 excel 表,并且在我调用该函数后网页会关闭,但是当我在我的 apache 服务器上调用它时会出现错误: ERR_INVALID_RESPONSE
,我浏览了放置 die() 的代码;在每一行之后查看它会如何响应,直到在$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
之后放置一个 die() 它会下载电子表格,但它会被损坏并且不会关闭页面并且它不会显示该错误消息,但是显然$objWriter->save('php://output');
导致出现错误,页面将冻结,并且无法下载 excel 文件。
我调试了别人的代码,但我无法弄清楚这部分。
【问题讨论】:
phpexcel to download 的可能重复项 【参考方案1】:最终问题出在 ZipArchive 类中,这就是它在一台服务器上工作而在另一台服务器上不起作用的原因。
更多文档在这里:http://www.php.net/manual/en/zip.installation.php
【讨论】:
【参考方案2】:我遇到了同样的问题。使用“php -m”检查它会为您提供模块列表并检查您是否安装了“zip”模块。 http://php.net/manual/en/book.zip.php
PhpExcel 需要此模块。如果您没有,请尝试安装或更改您的 php 版本。就我而言,我解决了将我的 php 从 7 更改为 php 5.5
【讨论】:
我建议您启用 Excel Lib 的所有要求: PHP 扩展 php_zip 已启用 PHP 扩展 php_xml 已启用 PHP 扩展 php_gd2 已启用 注意:不要忘记重新启动服务器。【参考方案3】:您可以尝试保存到临时文件并使用重定向来提供它:
$objWriter->save('wwwroot/some-file.xlsx');
header("Location: /some-file.xlsx");
exit();
【讨论】:
感谢您的回答,我在代码末尾添加了这个而不是$objWriter->save('php://output')
,但它仍然给了我相同的结果。【参考方案4】:
现在使用 php 7.4 你必须使用 --with-zip 选项
【讨论】:
【参考方案5】:在 php 7.4 中
//$objWriter=PHPExcel_IOFactory::createWriter($objPHPExcel,'Excel2007');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');
exit;
