微信小程序 实现朋友圈+评论+点赞

需求：

• 登录用户的好友列表
• 查看用户好友发布的所有动态
• 可以评论用户发表的动态
• 展示动态下的评论
• 可以对用户发表的动态进行点赞/取消点赞、分享、举报
• 可以发布动态

发布动态（文字、图文、列表）

/*
 * 发布动态
 */
public function store(Request $request)
{
    //接收数据
    $params = $request->all();
    //获取用户id
    $params['user_id'] = (new TokenServe())->checkToken($request->header('token'));
    //发布动态 将数据添加入库
    Message::create($params);
    return ['code'=>200,'msg'=>'发布成功','data'=>[]];
}

点赞+取消点赞

/*

 */

    //接收是哪个用户点赞的
    $user_id = (new TokenServe())->checkToken($request->header('token'));
    //查询该用户是否给该动态点过赞
    $res = MessageLike::where(['message_id'=>$message_id,'user_id'=>$user_id])->get()->toArray();
    if (empty($res)){
        //没点过赞 则点赞
        MessageLike::create(['message_id'=>$message_id,'user_id'=>$user_id]);
    }else{
        //点过赞 则取消点赞
        MessageLike::where(['message_id'=>$message_id,'user_id'=>$user_id])->delete();
    }
}

发表评论

/**
 * @param Request $request
 * @return array
 * 评论
 */
public function messageComment(Request $request)
{
    //接收评论的内容
    $params = $request->all();
    //获取评论的用户
    $params['user_id'] = (new TokenServe())->checkToken($request->header('token'));
    //添加入库
    MessageComment::create($params);
    return ['code'=>200,'msg'=>'评论成功','data'=>[]];
}

到这里就差不多完成了，细节需要自己优化，前端页面需要自己编写
