controller:

   public function goodsList(){if (request()->isGet()) {//表单验证//调用发布$where = [];$goodname = $this->request->param('goodname', '');if(!empty($goodname)){$where[] = ['name','like',$goodname];}return $this->logic->goodsList($where, $this->page, $this->size);}return '';}

logic：

  public function goodsList($search = null, $page = 1, $limit = 10){$lists = Goods::when(($search && is_array($search)), function ($query) use ($search) {$query->where($search);})->alias('good')->field("good.id,good.type,good.name,good.photo,good.price,good.introduction,good.tag")->order('id', 'desc')->paginate($limit, false, ['page' => $page]);return $this->success("获取数据成功", $lists);}

测试的结果：

奇怪的是当我直接搜 ：马抗  无数据 

解决办法：加上通配符

    public function goodsList(){if (request()->isGet()) {//表单验证//调用发布$where = [];$goodname = $this->request->param('goodname', '');if(!empty($goodname)){$goodname = '%' . $goodname . '%';$where[] = ['good.name','like',$goodname];}return $this->logic->goodsList($where, $this->page, $this->size);}return '';}
