将参数从内容类型传递到模块 [英] passing a parameter from a content type to a module

问题描述

我以为这很容易，但是我很沮丧.

I assumed this would be easy but I am stumped.

我有一个包含id字段的自定义内容类型.我用一个基本的页面模板来渲染它们.

I have a custom content type that includes an id field. I render these with a basic page template.

我已经编写了一个小模块，该模块创建了一个块，并在其中填充了来自外部API的数据.一切正常，但我似乎无法弄清楚如何将给定页面内容中的id值传递给模块，以便可以进行API调用.

I have written a small module that creates a block which is populated with data from an external API. Everything works except I cannot seem to figure out how to pass the value of the id from the content of a given page to my module so it can make the API call.

在直接的php中将是几行代码，在Drupal 8和twig中不会那么复杂吗?

It would be a couple of lines of code in straight php, it can't be that complicated in Drupal 8 and twig can it?

我设法找到了解决方法

如果有其他用途，我会重新发布它.

I am re-posting it in case it is useful to anyone else.

如果您要生成自定义块，则可以通过块构建函数内部的路由系统访问内容字段，如下所示:

If you are generating a custom block you can access content fields via the routing system inside your block build function like this:

public function build() {

    if ($node = \Drupal::routeMatch()->getParameter('node')) {
      $field_my_custom_value = $node->field_my_custom_value->value;
    }

    //do something with the variable, like make the API call

    //Make sure to set the cache to the context or even to zero if you need
    return array(
      '#markup' => $this->t('my content to render'),
      '#cache' => array(
         'contexts' => ['contexts' => ['route']],
      ),
   );
}
