MSOFFICE MIME类型验证 [英] MSOFFICE MIME type verification

问题描述

  $ mimeTypes = array（'application / msword'）; //曾经是一个数组
 
 $ finfo = new finfo（FILEINFO_MIME，/ usr / share / misc / magic）; 
 
 
 $ type = $ finfo-> file（$ _ FILES ['userfile'] ['tmp_name']）; 
 $ mime = substr（$ type，0，strpos（$ type，';'））; 
 
 $ b $ if（in_array（$ mime，$ mimeTypes））
 {//让它进入
  

问题在于我正在将application / vnd.ms-office作为我试图上传的任何MSOFFICE文件的文件类型。我不希望允许所有MSOFFICE文件，只有.DOC的。有没有解决方法？

请注意，这些MSOFFICE类型文件是在OPENOFFICE中创建的，这会有所作为吗？

解决方案

最好的办法是在知道文件是Office文档（ application / vnd.ms-office ）后验证文件扩展名。手动设置当前文件的正确MIME。

如果你有权访问Apache，你可以在 conf / mime.types

  application / msword doc 
 application / vnd.ms-excel xls 
 [...]等

 .potm application / vnd.ms-powerpoint.template.macroEnabled.12 
 .ppsm application / vnd.ms-powerpoint.slideshow.macroEnabled.12 
  

I have the following:

$mimeTypes = array('application/msword'); //used to be an array

$finfo = new finfo(FILEINFO_MIME, "/usr/share/misc/magic"); 


$type = $finfo->file($_FILES['userfile']['tmp_name']);
$mime = substr($type, 0, strpos($type, ';'));


    if (in_array($mime, $mimeTypes)) 
      { //let it in

The problem is that I am getting "application/vnd.ms-office" as the filetype for any MSOFFICE file that I attempt to upload. I DO NOT wish to allow all MSOFFICE files, only .DOC's. Is there a workaround for this?

**Please note that these MSOFFICE type files were created in OPENOFFICE, would this make a difference?

解决方案

The best you can do is verify file extension after know the file is a Office document (application/vnd.ms-office) and set manually the correct MIME for current file.

If you have access to Apache, you can add the correct MIME in conf/mime.types

application/msword doc
application/vnd.ms-excel xls
[..] etc
