我正在尝试使用 page_attachments 挂钩将开放图元标记动态添加到 drupal 8。元标记生成正确，但图像和网站 url 正在由 drupal 编码，结果是断开的链接。function module_page_attachments(array &$page){ $tags = [ ["name" => "twitter:card", "content" => "summary"], ["name" => "og:url", "content" => "https://example.net/index.php?param1=1¶m2=2¶m3=3"], ["name" => "og:title", "content" => "My title"], ["name" => "og:description", "content" => "My description"], ["name" => "og:image", "content" => "https://example.net/images?id=1&size=400"], ]; foreach ($tags as $tag) { $headerTag = array( '#tag' => 'meta', '#attributes' => array( 'property' => $tag['name'], 'content' => $tag['content'], ), ); $page['#attached']['html_head'][] = [$headerTag, $tag['name'] . "Id"]; }}结果如下<html><head> <meta charset="utf-8" /> <meta property="twitter:card" content="summary" /> <meta property="og:url" content="https://example.com/index.php?param1=1&param2=2&param3=3" /> <meta property="og:title" content="My title" /> <meta property="og:description" content="My description" /> <meta property="og:image" content="https://example.net/images?id=1&size=400" /></head><body></body></html>所有的&字符都被编码并转化为&. 如何防止 Drupal 对字符进行编码？

DrupalCoreRenderMarkup应该可以解决问题：
<?php
use Drupal\Core\Render\Markup;
function module_page_attachments(array &$page)
{
$tags = [
["name" => "twitter:card", "content" => "summary"],
["name" => "og:url", "content" => Markup::create("https://example.net/index.php?param1=1¶m2=2¶m3=3")],
["name" => "og:title", "content" => "My title"],
["name" => "og:description", "content" => "My description"],
["name" => "og:image", "content" => Markup::create("https://example.net/images?id=1&size=400")],
];
foreach ($tags as $tag) {
$headerTag = array(
'#tag' => 'meta',
'#attributes' => array(
'property' => $tag['name'],
'content' => $tag['content'],
),
);
$page['#attached']['html_head'][] = [$headerTag, $tag['name'] . "Id"];
}
}

needs work在 drupal 的网站上有一个关于状态问题的公开票。
解决此问题的一种方法是拦截页面并在模块文件中更改其模板，如下例所示：
文件名：example.module
/**
* Drupal bug caused the application to escape links. Therefore the og:image and og:url
* were not working. Drupal kept converting `&` to `&`
* The solution here below converts the tags into inline templates
*/
function spa_seo_page_attachments_alter(array &$attachments)
{
if (isset($attachments['#attached']['html_head'])) {
foreach ($attachments['#attached']['html_head'] as $key => $item) {
$property = !empty($item[0]['#attributes']['property']) ? $item[0]['#attributes']['property'] : '';
if ($property == "og:url" || $property == "og:image") {
$content = $item[0]['#attributes']['content'];
$property = $item[0]['#attributes']['property'];
$attachments['#attached']['html_head'][$key][0] = [
'#type' => 'inline_template',
'#template' => "{{ meta|raw }}",
'#context' => [
'meta' => '<meta property="' . $property . '" content="' . $content . '" />',
]
];
}
}
}
}
笔记
请注意，这DrupalCoreRenderMarkup并不能解决问题，因为这是一个错误。
