我正在嘗試使用 page_attachments 掛鉤將開放圖元標記動態添加到 drupal 8。元標記生成正確，但圖像和網站 url 正在由 drupal 編碼，結果是斷開的鏈接。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"]; }}結果如下<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&字符都被編碼并轉化為&. 如何防止 Drupal 對字符進行編碼？

DrupalCoreRenderMarkup應該可以解決問題：
<?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 的網站上有一個關于狀態問題的公開票。
解決此問題的一種方法是攔截頁面并在模塊文件中更改其模板，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 . '" />',
? ? ? ? ? ]
? ? ? ? ];
? ? ? }
? ? }
? }
}
筆記
請注意，這DrupalCoreRenderMarkup并不能解決問題，因為這是一個錯誤。
