[英]Webkit and Excel file(PHPexcel)
我有一个可以下载的excel文件。例如NAME.xlsx它可以在firefox中运行但是在webkit(safari / chrome)中它还附加了名称扩展名.xhtml,因此它的名称将是NAME.xlsx.html它应该只有.xlsx
在这里你有我的标题:
$objWriter = new PHPExcel_Writer_Excel2007($objPHPExcel);
$objWriter->save($root.'/application/to_excel/KSW.xlsx');
$this->getResponse()->setHeader('Content-type', 'application/download', true);
$this->getResponse()->setHeader('Content-type', 'application/octet-stream', true);
$this->getResponse()->setHeader('Content-type', 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet', true);
$this->getResponse()->setHeader('Content-disposition', 'attachment;filename='.basename($root.'/application/to_excel/KSW.xlsx').'', true);
$this->getResponse()->setHeader('Cache-Control', 'max-age=0', true);
那么我做错了什么?
我还没有让这个功能失败 - 它适用于我迄今为止在Safari(Windows)和Chrome中尝试过的所有Office 2007/2010文件。 get_known_mime_types()函数只返回我的应用程序支持的所有mime类型的巨大数组 - 只需Google就可以获得所需的MIME类型。 $file
是主机上$file
的实际路径, $name
是下载(运行/保存)对话框中显示的文件名。 我也得到了应有的信任,我得到了大部分的地方。 希望你也有运气:
function file_download($file, $name, $mime_type='') {
/* The majority of this code was taken from:
* http://w-shadow.com/blog/2007/08/12/how-to-force-file-download-with-php/
*
* So a big thanks to them.
* I have modified parts of it, though, so it's not 100% borrowed.
