API

1.全表查詢

public function query()
{
  $sql = "查詢語句";
  $query = $this->db->query($sql);
  $this->output->set_output(json_encode($query->result()));
}

2.帶引數查詢（get請求）

public function queryByParam($param)
{
  $sql = "查詢語句 where 欄位＝{$param}";
  $query = $this->db->query($sql);
  $this->output->set_output(json_encode($query->result()));
}

3.帶引數查詢（post請求）

public function detail()
{
  $jsonStr = $this->input->raw_input_stream;
  $jsonObj = json_decode($jsonStr); 
  $param = $jsonObj->id;
  $sql = "查詢語句 from 表名 where 欄位 = `{$param}` ";
  $query = $this->db->query($sql);
  $resData = $query->result();
  $this->output->set_output(json_encode($resData));
}

4.分頁查詢

public function paginate()
{
  $jsonStr = $this->input->raw_input_stream;
  $jsonObj = json_decode($jsonStr); 
  $page = $jsonObj->page;    //$page=1
  $limit = $jsonObj->limit;  //$limit=2
  if($page < 1 )
  {
     $page = 1;
  }
  $tmp = ($page-1)*$limit;
  $sql = "查詢語句 from 表名 limit {$tmp},{$limit}";
  $query = $this->db->query($sql);
  $this->output->set_output(json_encode($query->result()));
}

5.儲存

public function save()
{
  $jsonStr = $this->input->raw_input_stream;
  $jsonObj = json_decode($jsonStr);
  $params = array(
    `id` => $jsonObj->id,
    `name` => $jsonObj->title,
    `content` => $jsonObj->content
  );
  $this->db->insert(`表名`,$params);
  $this->output->set_output($this->db->affected_rows());
}
