在浏览器中使用php显示.msg文件

Question

我已经在PHP应用程序中附加了Outlook msg文件。 我将该文件存储在sql服务器数据库中。

现在，我想从浏览器中打开并显示它。

我尝试了这段代码：

  if($ext=="msg")
  {
    header('ContentType : application/octet-stream');
    header('Content-Disposition: attachment; filename='. basename($filename));
    echo base64_decode($file);
  }

$ filename和$ file来自数据库。

在IE和chrome中，它会在Outlook中打开msg文件，但在firefox中不会打开它。

有什么方法可以使其在所有浏览器中正常工作吗？

还是我在某个地方出错或浏览器中有任何设置吗？

Answer 1

我遇到了几乎类似的情况，并且能够解决它。 包括下面的标题，它应该可以正常工作。

header("Pragma: public");
header("Expires: 0");
header('Content-Encoding: UTF-8');
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-type: application/vnd.ms-outlook;charset=UTF-8"); 
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=test.msg");
header("Content-Transfer-Encoding: binary ");

Answer 2

if($ext=="msg")
  {
    header("Content-Type: text/Calendar");
    header('Content-Disposition: inline; filename='. basename($filename));
    echo base64_decode($file);
  }
