控制器代码

文章点赞操作
public function zan(Request $request){ //点赞的文章id $newid=$request->param('tid'); //获取用户id $uid=session('user')['id']; //使用redis存入数据 $redis = new redist(); $redis->connect('127.0.0.1', 6379); // $redis->flushAll(); //取出关于这个文章所有点赞过的用户id $uidArray= $redis->SMEMBERS ($newid); if (in_array($uid,$uidArray)) return json(['code'=>500,'msg'=>'不能重复点赞']); if ($redis->sAdd($newid,$uid)) return json(['code'=>200,'msg'=>'点赞成功']); return json(['code'=>500,'msg'=>'点赞失败']); }
