在视图中从公用文件夹访问资产（Laravel）

Question

I cannot access assets in my view.

Here is my code.

 $mail->addAttachment(asset($file), 'receiptFile', 'base64', 'application/octet-stream');

The browser shows the following error:

Could not access file: http://localhost/receiptGenerator2/public/5a46187d954de.png Message could not be sent.Mailer Error: Could not access file: http://localhost/receiptGenerator2/public/5a46187d954de.png ------

As you can see the path to the file was successfully located.

If Laravel can find the file,why is it showing the error.

Answer 1

Please try that way Use asset and give image name and if file is any folder than give {{ asset('folder_name/image_name') }}

{{ asset('5a46187d954de.png') }}

Its generate http://localhost/receiptGenerator2/public/5a46187d954de.png

Answer 2

Try this:

->attach(
   public_path('receiptGenerator2/public/5a46187d954de.png'), [
   'as' =>"attachment.png" ,
   'mime' => 'application/octet-stream',
]);

Edit: Since you're using phpmail this should do the trick

 $mail->addAttachment(public_path($file), 'receiptFile', 'base64','application/octet-stream');

Mail requires the full path, yes you can open the file from that url from the browser but the phpmailer attempts to access http://localhost/receiptGenerator2/public/5a46187d954de.png in your disk, so it tries to get the file from /var/www/html/project/ http://localhost/receiptGenerator2/public/5a46187d954de.png which is not valid.

Answer 3

As the docs for addAttachment() say, the first parameter must be a local file system path; it will not work if you give it a URL. PHPMailer isn't an HTTP client - there are many other functions and libraries to help with that, so use them if you need to fetch something from a remote URL to use as an attachment. You should not be using localhost URLs for local resources anyway as it's unnecessarily inefficient.
