通过PHP服务.docx文件 [英] Serving .docx files through Php

问题描述

尝试使用Php提供.docx文件时遇到问题.上传文件时，我会检测到文件的mime类型，并使用根据mime类型具有正确扩展名的文件来上传文件；例如下方:

I'm having issues when attempting to serve a .docx file using Php. When uploading the file I detect the file mime type and upload the file using the file with the correct extension based on the mime type; e.g. below:

application/msword - doc
application/vnd.openxmlformats-officedocument.wordprocessingml.document - docx

当尝试提供要下载的文件时，我会根据检测到的扩展名和基于例如MIME类型的服务进行相反的操作.

When attempting to serve the files for download, I do the reverse in detecting the extension and serving based on the mime type e.g.

public static function fileMimeType($extention) {

        if(!is_null($extention)) {
            switch($extention) {
                case 'txt':
                    return 'text/plain';
                    break;
                case 'odt':
                    return 'application/vnd.oasis.opendocument.text';
                    break;
                case 'doc':
                    return 'application/msword';
                    break;
                case 'docx':
                    return 'application/vnd.openxmlformats-officedocument.wordprocessingml.document';
                    break;
                case 'jpg':
                    return 'image/jpeg';
                    break;
                case 'png':
                    return 'image/png';
                    break;
                case 'pdf':
                    return 'application/pdf';
                    break;
                default:
                    break;
            }
        }

}

所有文件似乎都可以正确下载并可以正常打开，但是当尝试打开docx文件时，Word(在多个文件上)会引发错误，指出文件已损坏.

All files appear to download correctly and open fine but when attempting to open a docx file, Word (on multiple files) throws a error stating the file is corrupt.

任何想法都很棒，谢谢.

Any ideas would be great, thanks.

try {

 $file = new Booking_Document((int)$get_data['bookingDocument']);
 header('Content-Type: ' . Booking_Document::fileMimeType($file->getDocumentType()));
 header('Content-Disposition: attachment; filename=' . $file);
 header('Expires: 0');
 header('Cache-Control: must-revalidate, post-check=0, pre-check=0');
 header('Pragma: public');
 echo readfile(Zend_Registry::get(static::$_uploadDir).$this->_id);
} catch (Exception $e) {
 View_Helpers_FlashMessages::addMessage(array('message' => $e->getMessage(), 'type' => 'error'));
}
exit;

已修复

在调用readfile()之前，我添加了ob_clean()和flush()，它们似乎已解决了该问题.

Prior to calling readfile() I added ob_clean() and flush() which appears to have fixed the problem.
