Laravel routing: How to create a link to a PDF file
提问by user2746374
I need to generate PDF documents and have them send by email as well as make them reachable by a link. Sending by email is OK, but I have no idea how to create the link.
我需要生成 PDF 文档并让它们通过电子邮件发送以及通过链接访问它们。通过电子邮件发送可以，但我不知道如何创建链接。
Since I use Laravel 4, all links are going through routes.php.
So how do I create a link to a file at a given directory?
由于我使用 Laravel 4，所有链接都通过routes.php. 那么如何在给定目录中创建指向文件的链接？
<a href="http://my.domain.org/assets/pdf/file.pdf">Link</a>
will not work, since the route is not known by laravel...
将不起作用，因为 laravel 不知道该路线...

To generate a link to a physical file or directory, that you don't want to run through Laravel's application (e.g. through index.php), use URL::asset().
要生成指向物理文件或目录的链接，您不想通过 Laravel 的应用程序（例如通过 index.php）运行，请使用URL::asset().
URL::asset('assets/pdf/file.pdf');
This assumes you've created a physical PDF file on your server that you want to link to. If your PDF file is dynamic and generated/retrieved through your Laravel application, you should use URL::to(), URL::route(), or similar.
这假设您已经在要链接到的服务器上创建了一个物理 PDF 文件。如果你的PDF文件是动态的，并通过您Laravel应用程序生成/检索到的，你应该使用URL::to()，URL::route()或类似的。

Martin Tale is right, but this is another way of accomplishing the same using Laravel's Blade:
Martin Tale 是对的，但这是使用 Laravel's Blade 完成相同任务的另一种方式：
{{ link_to('/assets/pdf/file.pdf', 'Link') }}

Create that PDF somewhere in public directory and then create a link to that file like this:
在公共目录中的某处创建该 PDF，然后创建指向该文件的链接，如下所示：
URL::to('path/to/public/directory/file.pdf')

if you are using laravel 4's MAIL feature you can add this to it
如果您使用的是 laravel 4 的 MAIL 功能，您可以将其添加到其中
$message->attach($pathToFile);
but the .pdf in your public directory under a pdf folder and that will make it:
但是 pdf 文件夹下公共目录中的 .pdf 将使它：
$message->attach('pdf/mypdffile.pdf');
the same can be for a link which you can add to the email
您可以添加到电子邮件中的链接也是如此
{{ URL::to('pdf/mypdffile.pdf') }}
You shouldn't need a route to create a link it can be done by blade.
您不需要路由来创建可以由刀片完成的链接。

Another way, in a view:
另一种方式，在一个视图中：
<a href="{{ asset('/your_pdf_file.pdf') }}">some text</a>
This link will go to publicfolder.
此链接将转到public文件夹。
