Wordpress PHP在Bootstrap Carousel中输出相同的post ID

<div id="myCarousel" class="carousel slide" data-ride="carousel">
  <!-- Indicators -->
  <ol class="carousel-indicators">
    <?php
    $args = array(
      'post_type' => 'post',
      'posts_per_page' => 5 // 设置要显示的文章数量
    );
    $query = new WP_Query($args);
    $count = 0;
    while ($query->have_posts()) {
      $query->the_post();
      $active = ($count == 0) ? 'active' : ''; // 第一张图片添加active类
      echo '<li data-target="#myCarousel" data-slide-to="' . $count . '" class="' . $active . '"></li>';
      $count++;
    }
    wp_reset_postdata();
    ?>
  </ol>

  <!-- Wrapper for slides -->
  <div class="carousel-inner">
    <?php
    $args = array(
      'post_type' => 'post',
      'posts_per_page' => 5 // 设置要显示的文章数量

    $count = 0;
    while ($query->have_posts()) {
      $query->the_post();
      $active = ($count == 0) ? 'active' : ''; // 第一张图片添加active类
      echo '<div class="item ' . $active . '">';
      echo '<a href="' . get_permalink() . '">' . get_the_post_thumbnail() . '</a>'; // 输出文章特色图片
      echo '<div class="carousel-caption">';
      echo '<h3>' . get_the_title() . '</h3>'; // 输出文章标题
      echo '<p>' . get_the_excerpt() . '</p>'; // 输出文章摘要
