记录下thinkphp5自定义底层基类、内部类函数使用笔记大部分笔记来自tp手册。php

底层经常使用代码的封装

在控制器中基类的起着相当重要的做用,整个项目的代码安全,复杂程度,易读性都要看你项目的基类架构的.html

好比api中都须要某一个功能函数，咱们就能够写在基类里。ajax

贴上一个基类返回错误码的例子:thinkphp

<?php


namespace app\member\controller;
class Base extends \app\base\controller\Base
{

    static public function showReturnCode($code = '', $data = [], $msg = '')
    {
        $return_data = [
            'code' => '500',
            'msg' => '未定义消息',
            'data' => $code == 1001 ? $data : [],
        ];
        if (empty($code)) return $return_data;
        $return_data['code'] = $code;
        if(!empty($msg)){
            $return_data['msg'] = $msg;
        }else if (isset(ReturnCode::$return_code[$code]) ) {
            $return_data['msg'] = ReturnCode::$return_code[$code];
        }
        return $return_data;
    }

    static public function showReturnCodeWithOutData($code = '', $msg = '')
    {
        return self::showReturnCode($code,[],$msg);

    }

}

基类:数据库

<?php
namespace app\base\controller;

class ReturnCode
{
    static public $return_code = [
        '1001' => '操做成功',
        '1002' => '你想作什么呢', //非法的请求方式 非ajax
        '1003' => '请求参数错误', //如参数不完整,类型不正确
        '1004' => '请先登录再访问', //未登陆 或者 未受权
        '1005' => '请求受权不符', ////非法的请求  无受权查看
        '1006' => '数据加载失败', //
        '1010' => '数据不存在', //
        '1020' => '验证码输入不正确', //
        '1021' => '用户帐号或密码错误', //
        '1022' => '用户帐号被禁用', //
        '1030' => '数据操做失败', //
    ];
}

而后就能够调用了json

    private function getUid(){
        //数据库字段 网页字段转换
        $param = [
            'userid' => 'userid',
            'userpwd' => 'userpwd',
            'mobile' => 'mobile',
        ];
        $param_data = $this->buildParam($param);
        if (empty($param_data['userid'])&&empty($param_data['mobile'])) return self::showReturnCodeWithOutData(1003);
        $check_login = $this->doModelAction($param_data, 'base/Member.login', 'base/Member', 'checkLogin');
        if (!isset($check_login['code'])) $this->showReturnCodeWithSaveLog(1111);
        if ($check_login['code'] == 1001) {


        }
        return $check_login;

    }

框架构造函数使用

构造函数在类的初始化时候执行的一个方法,构造函数中不要使用return关键词。api

那么咱们常常在构造函数里面作作什么呢?浏览器

数据初始化注入对象等
前置工做的处理
权限判断

咱们看一下TP5 控制器的构造函数,他在初始化时候注入了request对象,咱们继承了控制器,直接就可使用$this->request调用,同时也封装了View类.同时对前置的beforeActionList属性的方法进行处理.安全

public function __construct(Request $request = null)
    {
        if (is_null($request)) {
            $request = Request::instance();
        }
        $this->view    = View::instance(Config::get('template'), Config::get('view_replace_str'));
        $this->request = $request;

        // 控制器初始化
        $this->_initialize();

        // 前置操做方法
        if ($this->beforeActionList) {
            foreach ($this->beforeActionList as $method => $options) {
                is_numeric($method) ?
                $this->beforeAction($options) :
                $this->beforeAction($method, $options);
            }
        }
    }

对于权限判断的例子:微信

public function _initialize()
    {
        parent::_initialize(); // TODO: Change the autogenerated stub
        $user_agent = $this->request->server('HTTP_USER_AGENT');
        if (! strpos($user_agent, 'MicroMessenger') === false ) $this->isWechatBrowser = true;
        //判断提交方式和是否微信浏览器
        if ($this->request->method() == 'GET' && $this->isWechatBrowser === true){
            //未登陆 从新登陆
            if (!$this->checkAuth()&& !$this->no_login )  $this->wxoauth();
            $this->isLogin=true;
            //设置全局登陆
            $this->loginGlobal();
            if(!$this->isReg){
                if(!$this->checkUuidMobile()) $this->redirect('user/user_blind.html');
            }
        }

    }

控制起来继承:

<?php

namespace app\api\controller;


class WxpayAction extends Auth
{
    public function _initialize()
    {
        config('default_return_type','html');
        parent::_initialize(); // TODO: Change the autogenerated stub
    }

    public function index($order_no='2017020453102495'){

        if(!$this->isWechatBrowser){
         //*******
         为了演示方便 这里省略了订单的是否支付验证
         
         另外 微信支付自己就有支付重复验证 这里并无加入乐观锁过滤 
         //*******
        $data=controller('base/WxPay')->payByOrderNo($order_no);
        $assign_data=[
            'title'=>'为了家健康--订单支付',
            'amount'=>$data['amount'],
            'order_no'=>$order_no,
            "jsApiParameters" =>$data['jsApiParameters'],
            'openid'=>$this->open_id,
            'data_md5'=>md5($order_no.$this->open_id.$data['amount']), //md5验证( 订单号 openid 金额)

        ];

        $this->assign($assign_data);
        return $this->fetch('wxpay/index');

    }


    public function showOrdersPayOk($order_no,$order_amount,$data_md5){
        //md5验证( 订单号 openid 金额)
        if (md5($order_no.$this->open_id.$order_amount)<>$data_md5){
            $assign_data=[
                'title'=>'为了家健康--支付出错了',
                'content'=>'你要支付的订单号不存在请核对后再支付!',
            ];
            $this->assign($assign_data);
            return $this->fetch('wxpay/err');
        }else{

            $assign_data=[
                'title'=>'为了家健康--该订单已经支付成功',
                'amount'=>$order_amount,
                'order_no'=>$order_no,
            ];
            $this->assign($assign_data);
            return $this->fetch('wxpay/ok');
        }
    }

    public function jsSign($url=''){
        $url= $url ? : $this->request->server('HTTP_REFERER');
        return json(controller('base/WxApi')->getJsSign($url));
    }

框架析构函数使用

析构函数就是一个收尾的一个方法,

例子:建立一个虚拟基类

<?php
namespace app\base\controller;

use think\Cache;
use think\Controller;
use think\Session;
use think\Loader;

abstract class Base extends Controller
{
    protected $error;             //出错时候的记录
    protected $log=[];            //要保存的记录
    protected $saveLog = false ;
    
    
    static public function showReturnCode($code = '', $data = [], $msg = '')
    {
        $return_data = [
            'code' => '500',
            'msg' => '未定义消息',
            'data' => $code == 1001 ? $data : [],
        ];
        if (empty($code)) return $return_data;
        $return_data['code'] = $code;
        if(!empty($msg)){
            $return_data['msg'] = $msg;
        }else if (isset(ReturnCode::$return_code[$code]) ) {
            $return_data['msg'] = ReturnCode::$return_code[$code];
        }
        return $return_data;
    }
    
        protected function addLog($code='',$msg=''){
        $this->log[] =[
            'uuid' => $this->uuid,
            'url' => $this->request->url(true),
            'method' => $this->request->method(),
            'data' => $this->getData(),
            'ip' => $this->request->ip(),
            'code'=>$code,
            'desc' => $msg,
        ];
    }
    protected function toSaveLog(){
        $this->saveLog = true ;
        $this->addLog();
    }

    protected function showReturnCodeWithSaveLog($code = '', $data = [], $msg = ''){
        $this->saveLog = true ;
        $this->addLog($code,$msg);
        return self::showReturnCode($code, $data, $msg);
    }
    
    protected function getData(){
        if ($this->request->isPost()){
            return $this->request->post();
        }else{
            return $this->request->get();
        }
    }
    protected function saveLogAction(){
        if (!empty($this->log)){
            foreach($this->log as $value){
                dump($value);
            }
        }
    }

    public function __destruct()
    {
        // TODO: Implement __destruct() method.
        //记录日志
        if (!empty($this->log) && $this->saveLog == true){
            $this->saveLogAction();
        }
    }
}

控制器继承:

<?php

namespace app\member\controller;
use app\base\model\Member;
use think\Cache;
use think\Db;

class Test extends Base
{

    public function index(){

       return $this->showReturnCodeWithSaveLog(1001,'演示析构函数成功了');

    }



}
