如何在Wordpress页面中放置结构化数据标记中的markup.html

我的Google analytics帐户建议我将结构化数据标记添加到标题部分的网页中。我标记了我想要的内容并创建了HTML。但是，当我将代码放在我标记的页面的HTML中时，我不会看到标题部分。所以，我只是把它放在页面的顶部。当我将其添加到页面顶部时，它会创建一个空间。可以把这个代码放在页面底部吗。代码如下所示：

 <script type="application/ld+json">
 [ {
 "@context" : "http://schema.org",
 "@type" : "Product",
  "description" : "IT Training Courses",
  "url" : "https://mindiq.com/it-training-course-list-application- 
   development- 
    java/"
    }, {
   "@context" : "http://schema.org",
   "@type" : "Product",
  "description" : "IT Training Courses",
  "url" : "https://mindiq.com/pythonl-training-onsite-tailored-low-cost/"
   } ]
  </script>

[ {
“@context”：”http://schema.org",
“@type”：“产品”，
“说明”：“IT培训课程”，
“url”：”https://mindiq.com/it-training-course-list-application- 
发展-
java/”
}, {
“@context”：”http://schema.org",
“@type”：“产品”，
“说明”：“IT培训课程”，
“url”：”https://mindiq.com/pythonl-training-onsite-tailored-low-cost/"
} ]

看看这里：

<?php
add_action('wp_head', 'your_function');
?>

function your_function() {
?>
