Drupal 8：如何编辑“段落”字段值？

问题描述

我想知道是否可以设置一个段落的值。 在我的模块中，我使用了entity_presave函数，如果我尝试获取Paragraph值，则其工作正常，但是如果我尝试设置或编辑值，则其以某种方式无法工作。

function setParagraph($node)
{
  $paragraph = $node->field_paragraphs->getValue();
  // Loop through the result set.
  foreach ($paragraph as $element) {
    $p = \Drupal\paragraphs\Entity\Paragraph::load($element['target_id']);
    $foo = $p->field_foo>value;
    $bar = $p->field_bar->value;

`$foo and $bar are getting filled with the right values`

but if i want to set a value nothing will work 

    $p->set('field_foo',$bar); //not working
    $p->field_foo = $bar;  //not working
    $p->field_foo->value = $bar; notworking
    //$p->set('field_steamconnect',$steamconnect);
  }
}

解决方法
