How can I get the URL to the public files directory?

Question

I can get the path to the public files directory by using Filesystem::realpath:

$path = $filesystem->realpath('public://');

But how can I get the URL of public://?

Answer 1

$my_path = file_create_url("public://"); 

Will definately work, however it's not coming from a service. Let me investigate more on this!

Okey I found it! This is how file_create_url works:

And this is the corresponding line specific to "public://" resolving (if you are sure you are trying to resolve a "public://..." uri):

  if ($wrapper = \Drupal::service('stream_wrapper_manager')->getViaUri($uri)) {
  return $wrapper->getExternalUrl();
}

Which means you will have to use StreamWrapperManager service, and after calling the getViaUri, you will able to get the external url. So this is service based solution!

Answer 2

After Drupal 9.3.3, you can do this with the field_url_generator service.

$url = \Drupal::service('file_url_generator')->generate('public://basename.ext'); 

This returns a path to the file like /sites/default/files/basename.ext.

Answer 3

Another way to achieve it.

$wrapper = \Drupal::service('stream_wrapper_manager')->getViaScheme(file_default_scheme());
return $wrapper::baseUrl();

will return DOMAIN/sites/default/files for my case. For 'public', $wrapper belongs to class "PublicStream", you can check other methods inside.

I've added it because this works for me:

$my_path = file_create_url("public://");

But this not work:

if ($wrapper = \Drupal::service('stream_wrapper_manager')->getViaUri($uri)) {
  return $wrapper->getExternalUrl();
}

in my project, it returns "public://".

Maybe it's related to update of Drupal Core or some settings. Unfortunately, it's not easy to find the root cause. I hope this information will be helpful for somebody.

I was having -

public://2019-03/YxoEy6.png

and I got the image by -

<img class="item-logo" src="{{file_url(restricted_item.logo_name.logo )}}" alt="logo" />

Answer 5

Drupal 9 and 10

Use the FileUrlGenerator service:

$urlEntity = \Drupal::service('file_url_generator')->generate($file->getFileUri())
$url = $urlEntity->toString();

// or

$url = \Drupal::service('file_url_generator')->generateString($file->getFileUri())
