How to get all posts from the current request?

Question

WordPress

I need to get all posts in the current request.

global $wp_query;
$posts = $wp_query->posts;

works fine if there are no parameters.
For example, if I make a selection by meta parameters

meta_key=color&meta_value=blue

adding them as a GET to the link, the posts are displayed correctly, however,
$posts = $wp_query->posts;
all posts are transferred here, without taking into account the selection by parameters
How can I get the posts in the current request, taking into account the selection by parameters?
