我正在重写功能，以将数据从Json文件获取到mysql。我的代码中有一个错误，我不知道在哪里。如果您希望发挥作用并告诉我在哪里做错了事，我将非常高兴。

代码：
public function getParameterMap()
{
return [
'file' => 'url',
'category' => ['categoryList']['name'],
'thumbnail' => ['assetList']['name'],
'tags' => ['tagList']['name'],
'name' => 'title'
];
}
/**
* @param FeedGame $game
* @param $feedData
* @return mixed
*/
public function filterGame(FeedGame $game, $feedData)
{
$game->setProviderId(substr(md5($feedData->name), 0, 5));
$game->setCategory(array([($feedData->categoryList->name)]));
$game->setThumbnail(array([($feedData->assetList->name)]));
$name = $feedData->title;
$description = $feedData->description;
$game->setTags(array([($feedData->tagList->name)]));
}
在将数据添加到mysql之后-在我的基础上，我在类别列-“数组”中看到。在标签列和缩略图列中，我也看到了“数组”。
在filterGame函数中-这里我出错了，我不知道该怎么写。 Json文件的数组中有数组，我不知道如何 吸引它。
您能帮我吗？
我想在mysql中使用-512x512缩略图和categoryList（json）中的第一类，以及所有标签列表，每个标签后均带有“”。
Ps-对不起我的英语-我是自己学的，可能我犯了很多错误。
