API接口笔记

1.基类

　   定义返回信息

    protected $user;                  //用户表
    protected $token;                 //用户token
    protected $isSuccess = FALSE;    //状态是否成功
    protected $msg = ‘操作成功‘;       //返回给开发者的数据
    protected $Usermsg;               //返回给用户的数据
    protected $api_code;              //接口名
    protected $code = 0;              //状态码
    protected $results;               //返回数据

定义返回成功的快捷信息

// 输出正确数据
  public function restSuccess($msgCode = ‘0|操作成功‘)
  {
    $this->isSuccess = True;
    $messageCode = explode(‘|‘,$msgCode);
    @$this->code  = $messageCode[0];
    @$this->msg   = $messageCode[1];
    unset($messageCode);
  }

定义返回失败的快捷信息

  // 输出错误数据
  public function restError($msgCode = ‘1|服务器繁忙|输入数据有误‘)
  {
    $this->isSuccess = False;
    $messageCode = explode(‘|‘,$msgCode);
    $this->code  = $messageCode[0];
    @$this->Usermsg = $messageCode[1];
    @$this->msg = $messageCode[2];
    unset($messageCode);
  }

定义整合的返回信息

// 整体输出返回数据
  public function response()
  {
      $data[‘api_code‘] = $this->api_code;
      $data[‘code‘] = $this->code;
      $data[‘isSuccess‘] = $this->isSuccess;
      $data[‘msg‘] = $this->msg;
      $data[‘Usermsg‘] = $this->Usermsg;
      $data[‘results‘] = $this->results;
      return $data;
  }

API健壮性

 // 检测设备
  private function checkDevice()
  {
    if(!isMobile()){
      $this->restError(config(‘errorMsg.notMobile‘));
      echo json_encode($this->response());
      exit();
    }

  }

  //检测请求方式
  private  function checkMethod()
  {
    if(!$this->request->isPost()){
      $this->restError(config(‘errorMsg.notMethod‘));
      echo json_encode($this->response());
      exit();
    }
  }

定义构造方法，使用TP5内置方法

public function _initialize()
{
      parent::_initialize();

      $this->api_code = input(‘api_code‘);

      $this->checkDevice();   // 检查设备
      $this->checkMethod();  //检测请求方式
      $this->checkLogin(); //检测登录
      //$this->checkApi();   // 检测APi
  }

2.缓存

// 浏览帖子
    public function index()
    {
        $info = cache(‘postindex‘);//查找缓存

        if(!$info){//如果缓存没有数据
            $list = new Mpost;//查找数据库
            $info = $list->i_ndex();
            cache(‘postindex‘,$info,3600);//设置缓存
        }
        $this->assign(‘arr‘, $info);
        return view(‘postd/index‘);
    }
