Question

我需要在持久功能内返回一个JsonResponse。

这是我的DataPersister类的示例，目标是返回JsonResponse，当我尝试时，出现错误：控制器必须返回一个\“ Symfony \ Component \ HttpFoundation \ Response \”对象，但它返回了一个对象类型为App \ Entity \ VerificationCodes。

game_hash = {
    :home => 
    {
        :team_name => "Brooklyn Nets",
        :colors => ["Black", "White"],
        :players => {
            :player1 => {
                :name => "Alan Anderson",
                :number => 0,

请帮助我或告诉我我能做的比你

如果您希望将App\Entity\Users类转换为JSON，则可以实现JsonSerializable接口（PHP本机接口）。该接口迫使您实现方法jsonSerialized，该方法在对象转换为json时会自动调用（例如，当您使用json_encode($user);时。）

最后，您可以尝试

class Users implements \JsonSerializable
{
    public function jsonSerialize()
    {
        return []; // an array representation of your class
    }
}

那么您可以...

return new JsonResponse(json_encode($user));

或（也许）...

return new JsonResponse($user);

Api Platform-Symfony-以持久功能返回json
