Wordpress wp_head（）标题标记不起作用

The problem is that on my one pager website the title tag doesn't get populated.

page.php looks like this:

<?php 

locate_template( 'page-home.php', true );

exit();

page-home.php looks like this:

<?php get_header(); ?>

<?php get_template_part('template-sections/slider'); ?>

<?php get_template_part('template-sections/services'); ?>

<?php //etc. ?>

<?php get_footer();

header.php looks like this:

<!doctype html>
<html <?php language_attributes(); ?>>
<head>
    <meta charset="<?php bloginfo( 'charset' ); ?>"/>
    <meta name="viewport" content="width=device-width, initial-scale=1"/>
    <link rel="profile" href="http://gmpg.org/xfn/11"/>
    <base href="<?php echo get_site_url(); ?>/">
    <?php wp_head(); ?>
</head>

<body itemprop="hasPart" itemscope="" itemtype="http://schema.org/WebPage" <?php body_class(); ?>>
<!-- etc -->

And footer.php looks like this:

            <?php wp_footer(); ?>
    </main>
    <aside class="aside">
        <div class="aside__content">
        </div>
    </aside>
</div>
</body>
</html>

Yes. There is a page present called home in the backend. And I would like Wordpress to pick that title up and use it as a title tag in header.php.

Now as far as I know, Wordpress normally automatically populates the title tag. So what's the problem here? Thanks!

PS: I am not using the wp_title filter anywhere in my custom Wordpress theme.

    Ok, the solution I found might help others. So I felt free to post it here.

    Part 1. Comparing with the standard twentyseventeen theme. I found that Wordpress needs add_theme_support( 'title-tag' ); to be able to manage the title. (Otherwise you should just add a <title> tag yourself in header.php, I guess.

    Part 2. I needed to add a custom filter to functions.php to display the title in a format that is desired. For example (using a SEO plugin): 

    function custom_title( $title_parts ) {
    $page_id   = site_get_page_id(); // custom function, you might want to use global $post here
    $seo_title = @get_post_meta( $page_id, '_aioseop_title' );

    if ( isset( $seo_title[0] ) ) {
        $title = $seo_title[0];
    } elseif ( isset( $page_id ) ) {
        $title = get_the_title( $page_id );
    }

    $page_title           = isset( $title ) ? $title : 'Page not found in backend';
    $title_parts['title'] = $page_title;

    return $title_parts;
}
