URL prefix for posts WordPress

So I have website on a WordPress engine. And I want to make posts urls looks like http://website.com/blog/post-name/ or http://website.com/blog/categ-name/post-name/. But everything else will look like http://website.com/page-name/. Just want to add prefix 'blog' to urls for all posts but not pages. My permalink settings is /%postname%/. If i will put /blog/%postname%/ I will have 'blog' prefix in every URL of my site 开发者_运维技巧:( I can't find solution in WordPress admin backend and I didn't find any acceptable plugin for this. Any help is appreciated, thanks.

1) Add this rewrite at the end of you function.php

function add_rewrite_rules( $wp_rewrite )
{
    $new_rules = array(
        'blog/(.+?)/?$' => 'index.php?post_type=post&name='. $wp_rewrite->preg_index(1),
    );

    $wp_rewrite->rules = $new_rules + $wp_rewrite->rules;
}
add_action('generate_rewrite_rules', 'add_rewrite_rules'); 

function change_blog_links($post_link, $id=0){

    $post = get_post($id);

    if( is_object($post) && $post->post_type == 'post'){
        return home_url('/blog/'. $post->post_name.'/');
    }

    return $post_link;
}
add_filter('post_link', 'change_blog_links', 1, 3);

2) Go to Settings > Permalinks and click Save Changes.

Create a category called blog and use the permalink structure /%category%/%postname%/.

Go to Settings > Permalinks, choose "Custom Structure" and rewrite this field to "/blog/%postname%/". Your post will get /blog/ prefix, but your pages doesn't. I've tested it at Wordpress 5.2.2

I did this:

add_action( 'init', 'redefine_post', 1 );
function redefine_post() {
    register_post_type( 'post', array(
        'labels' => array(
            'name_admin_bar' => _x( 'Post', 'add new on admin bar' ),
        ),
        'public'  => true,
        '_builtin' => false,
        '_edit_link' => 'post.php?post=%d',
        'capability_type' => 'post',
        'map_meta_cap' => true,
        'hierarchical' => false,
        'rewrite' => array( 'slug' => 'blog' ),
        'query_var' => false,
        'has_archive' => true,
        'supports' => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'trackbacks', 'custom-fields', 'comments', 'revisions', 'post-formats' ),
    ) );
}

It involves creating a custom post type (which is slightly annoying), but it overrides and works with post.

I wish there was a better way of doing this! (Otherwise yes you get /blog/ in front of everything if you just change the permalinks).

  $new_rules = array(
    '(([^/]+/)*blog)/page/?([0-9]{1,})/?$' => 'index.php?pagename=$matches[1]&paged=$matches[3]',
