构建查询

$query = Query::query('TestQueryWithEverything');
$query->defineFragment('userStuff', 'User');
$query->userStuff->fields('id', 'name', 'path');
$query->fields('scope', 'friends', 'viewer');
$query->friends->attribute('names', ['marc', 'jeff']);
$query->friends->fields('id', 'name', 'picture');
$query->friends->picture->attribute('size', 50);
$query->viewer->fields('...userStuff', 'repos');
$query->viewer->repos
	->attribute('public', true)
	->attribute('limit', 10)
	->attribute('order', ['field' => Query::enum('STARS'), 'direction' => Query::enum('DESC')]);
$query->viewer->repos->fields('id', 'path');
$query->viewer->repos->fragment('PublicRepo')->fields('stars');
$query->viewer->repos->fragment('PrivateRepo')->fields('status', 'permissions', 'members');
$query->viewer->repos->PrivateRepo->members->fields('...userStuff');

渲染结果

$string = $query->build();

结果为

query TestQueryWithEverything {
  scope
  friends(names: ["marc","jeff"]) {
    id
    name
    picture(size: 50)
  }
  viewer {
    ...userStuff
    repos(public: true, limit: 10, order: {field: STARS, direction: DESC}) {
      ... on PublicRepo {
        stars
      }
      ... on PrivateRepo {
        status
        permissions
        members {
          ...userStuff
        }
      }
      id
      path
    }
  }
}

fragment userStuff on User {
  id
  name
  path
}

突变

由于突变实际上与查询相同，因此具有完全相同的语义

$query = Query::mutation();
$query->field('moveProjectCard')->attribute('input', ['cardId' => 123, 'columnId' => 456]);
$query->moveProjectCard->fields('clientMutationId');

制作

mutation {
  moveProjectCard (input: {cardId: 123, columnId: 456}) {
    clientMutationId
  }
}
