PHP中使用getUnlimited获取小程序码使用scene蚕食是怎么使用的？ $param = json_encode(array("page"=>"livegroup/pages/index/index","scene"=>"fxid=123&goodid=3","isHyaline"=>true)); $param = json_encode(array("page" => "livegroup/pages/index/index","scene"=>"?fxid=123&goodid=3","isHyaline"=>true)); $param = json_encode(array("page" => "livegroup/pages/index/index","scene"=>array("fxid"=>123,"goodid"=>3),"isHyaline"=>true)); 哪一种方式是对的？前端获取是用options获取就行了吗？
