use League\Fractal\Manager;
use League\Fractal\Resource\Collection;
$articles = [
[
'id' => 1,
'title' => 'JSON API paints my bikeshed!',
'body' => 'The shortest article. Ever.',
'author' => [
'id' => 42,
'name' => 'John',
],
],
];
$manager = new Manager();
$resource = new Collection($articles, new ArticleTransformer());
$manager->parseIncludes('author');
$manager->createData($resource)->toArray();
?>如果让我选最喜爱的 PHP 工具包，Fractal 一定榜上有名，它隐藏了实现细节，让使用者完全不必了解 JSONAPI 协议即可上手。不过如果你想在自己的项目里使用的话，与直接使用 Fractal 相比，可以试试 Fractalistic ，它对 Fractal 进行了封装，使其更好用：
collection($articles) ->transformWith(new ArticleTransformer()) ->includeAuthor() ->toArray(); ?>
如果你是裸写 PHP 的话，那么 Fractalistic 基本就是最佳选择了，不过如果你使用了一些全栈框架的话，那么 Fractalistic 可能还不够优雅，因为它无法和框架本身已有的功能更完美的融合，以 Lavaral 为例，它本身内置了一个 API Resources 功能，在此基础上我实现了一个 JsonApiSerializer，可以和框架完美融合，代码如下：
resource = $resource;
$this->resourceValue = $resourceValue;
}
public function jsonSerialize()
{
foreach ($this->resourceValue as $key => $value) {
if ($value instanceof Resource) {
$this->serializeResource($key, $value);
} else {
$this->serializeNonResource($key, $value);
}
}
if (!$this->isRootResource()) {
return $this->data;
}
$result = [
'data' => $this->data,
];
if (static::$included) {
$result['included'] = static::$included;
}
if (!$this->resource->resource instanceof AbstractPaginator) {
return $result;
}
$paginated = $this->resource->resource->toArray();
$result['links'] = $this->links($paginated);
$result['meta'] = $this->meta($paginated);
return $result;
}
protected function serializeResource($key, $value, $type = null)
{
if ($type === null) {
$type = $key;
}
if ($value->resource instanceof MissingValue) {
return;
}
if ($value instanceof ResourceCollection) {
foreach ($value as $k => $v) {
$this->serializeResource($k, $v, $type);
}
} elseif (is_string($type)) {
$included = $value->resolve();
$data = [
'type' => $included['type'],
'id' => $included['id'],
];
if (is_int($key)) {
$this->data['relationships'][$type]['data'][] = $data;
} else {
$this->data['relationships'][$type]['data'] = $data;
}
static::$included[] = $included;
} else {
$this->data[] = $value->resolve();
}
}
protected function serializeNonResource($key, $value)
{
switch ($key) {
case 'id':
$value = (string)$value;
case 'type':
case 'links':
$this->data[$key] = $value;
break;
default:
$this->data['attributes'][$key] = $value;
}
}
protected function links($paginated)
{
return [
'first' => $paginated['first_page_url'] ?? null,
'last' => $paginated['last_page_url'] ?? null,
'prev' => $paginated['prev_page_url'] ?? null,
'next' => $paginated['next_page_url'] ?? null,
];
}
protected function meta($paginated)
{
return [
'current_page' => $paginated['current_page'] ?? null,
'from' => $paginated['from'] ?? null,
'last_page' => $paginated['last_page'] ?? null,
'per_page' => $paginated['per_page'] ?? null,
'to' => $paginated['to'] ?? null,
'total' => $paginated['total'] ?? null,
];
}
protected function isRootResource()
{
return isset($this->resource->isRoot) && $this->resource->isRoot;
}
}
?>对应的 Resource 基本还和以前一样，只是返回值改了一下：
'articles',
'id' => $this->id,
'name' => $this->name,
'author' => $this->whenLoaded('author'),
];
return new JsonApiSerializer($this, $value);
}
}
?>对应的 Controller 也和原来差不多，只是加入了一个 isRoot 属性，用来识别根：
article = $article;
}
public function show($id)
{
$article = $this->article->with('author')->findOrFail($id);
$resource = new ArticleResource($article);
$resource->isRoot = true;
return $resource;
}
}
