如何获取WordPress中的所有帖子标签？

$tags = get_tags();

if ( ! empty( $tags ) ) {
    echo '<ul>';
    foreach ( $tags as $tag ) {
        echo '<li><a href="' . get_tag_link( $tag->term_id ) . '" title="' . esc_attr( $tag->name ) . '">' . $tag->name . '</a></li>';
    }
    echo '</ul>';
}

fetch('https://your-wordpress-site.com/wp-json/wp/v2/tags')
    .then(response => response.json())
    .then(data => {
        console.log(data);
    })
    .catch(error => {
        console.error('Error:', error);
    });

$args = array(
    'taxonomy' => 'post_tag',
    'hide_empty' => false,
);

$tags_query = new WP_Query( $args );

if ( $tags_query->have_posts() ) {
    echo '<ul>';
    while ( $tags_query->have_posts() ) {
        $tags_query->the_post();
        $tag = get_term( get_the_ID(), 'post_tag' );
        echo '<li><a href="' . get_tag_link( $tag->term_id ) . '">' . $tag->name . '</a></li>';
    }
    echo '</ul>';
}

wp_reset_postdata();
