链接到html中的PDF，该文件没有扩展名，但我知道这是pdf如何使其正确打开 [英] Link to a PDF in html, the file has no extension, but I know it is pdf how to make it open appropriately

问题描述

第一篇文章。我正在为一个客户端的项目，他们有pdf文件上传到文件结构（LAMP堆栈），但文件没有扩展名。假设这些文件必须是PDF，我将如何让浏览器了解，并相应地打开它们？显然，通过添加文件扩展名，这将突然工作，但我不能改变他们的系统工作方式，这将导致太多的变化，他们在一个紧迫的截止日期。至于保存一个临时副本在某个地方，我可以这样做，但我希望一个更好的解决方案。有没有办法向浏览器建议他们以某种方式打开文件？

First post. I'm working on a project for a client where they have pdf files uploaded to a file structure (LAMP Stack) but the files have no extensions on them. Under the assumption that those files have to be PDF how would I get the browsers to understand that, and open them accordingly? Obviously with adding the file extensions this would suddenly work but I can't change the way their system works, it would result in too many changes and they are on a tight deadline. As for saving a temporary copy somewhere, I could do that, but I was hoping for a better solution. Is there a way to suggest to the browsers that they open a file a certain way?

任何想法家伙/ gals？

Any thoughts guys/gals?

推荐答案

您只需在标题中设置应用程序类型和文件名，如下所示：

You just set the application type and file name in the headers, like so:

// This points to the file in question, note that it doesn't 
// care whether it has an extension on the name or not.
$filePathOnDisk = '/path/to/your/pdffile';

// You can make this whatever you like, it doesn't have to 
// be the same as the file name on the disk! This is the name of the file your end 
// user will see when they are asked if they want to save. open, etc in the browser.
$fileName = 'file.pdf'; 

$data = file_get_contents($filePathOnDisk); 
header("Content-type: application/pdf");
header("Content-disposition: attachment;filename=$fileName");
echo $data;
