yii中的restful方式输出并调用接口和判断用户是否登录状态

//创建一个控制器接口  返回的是restful方式
<?php
namespace frontendcontrollers;
use frontendmodelsFenlei;
use frontendmodelsGoods;
use frontendmodelsPower;
use frontendmodelsUser;
use yii;
use yiiwebController;
use yii
estActiveController;
class RestfulController extends ActiveController
{
    protected  $result=[
        'code'=>0,
        'data'=>'',
        'error'=>''
    ];
    public $modelClass='';

    public function actions()
    {
        $actions=parent::actions();
        unset($actions['view'],$actions['index'],$actions['create'],$actions['delete'],$actions['update']);
        return $actions;
    }

    //登录页面
    public function actionLogin()
    {
        $data['name']=Yii::$app->request->post('name');
        $data['pwd']=Yii::$app->request->post('pwd');
        if(empty( $data['name']) || empty($data['pwd']))
        {
            $this->result['error']="用户名密码不能为空";
            $this->result['code']="1001";
            return $this->result;
        }
        $aa=User::user($data);
        if($aa)
        {
            Yii::$app->cache->set('name',1,7200);
            $token=md5($data['name'].$data['pwd']);
            $this->result['data']=$token;
            $this->result['error']="登录成功";
        }else{
            $this->result['error']="登录失败";
        }
        return $this->result;
    }
}

//然后通过另一个控制器来调用接口
<?php
namespace frontendcontrollers;
use frontendmodelsCurl;
use yii;
use yiiwebController;
use yii
estActiveController;
class LoginController extends Controller
{
    //登录页面
    public function actionLogin()
    {
        $name=Yii::$app->request->get('name');
        $pwd=Yii::$app->request->get('pwd');
        $curl = new Curl();
        $url='http://weixin.api.com/index.php/restful/login';
        $data=[
            'name'=>$name,
            'pwd'=>$pwd
        ];
        $aa=$curl->getCurl($url,'post',$data);
        //返回的是json数据
        $a=json_decode($aa,true);
        $token=$a['data'];
        file_put_contents('login.txt',$token);
        var_dump($token);
    }
}

//这是curl的方式调用
<?php
namespace frontendmodels;
class Curl
{
    public function getCurl($url,$type='get',$data,$https='true')
    {
        $ch = curl_init($url);
        curl_setopt($ch,CURLOPT_RETURNTRANSFER,true);
        if($type=='post')
        {
            curl_setopt($ch,CURLOPT_POST,1);
            curl_setopt($ch,CURLOPT_POSTFIELDS,$data);
        }
        if($https=='false')
        {
            curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,false);
            curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,false);
        }
        $data=curl_exec($ch);
        curl_close($ch);
        return $data;
    }
}

//判断用户是否登录的状态
<?php
namespace frontendcontrollers;
use frontendmodelsCurl;
use yii;
use yiiwebController;
class CatController extends Controller
{
   //判断用户是否存在
    public function init()
    {
        $name=Yii::$app->cache->get('name');
        if($name !=1)
        {
            Yii::$app->cache->set('name',2);
            return "请登录";
        }
    }

    //水果的添加
    public function actionAdd()
    {
        $data['g_goods']=Yii::$app->request->get('g_goods');
        $data['g_kc']=Yii::$app->request->get('g_kc');
        $data['id']=Yii::$app->request->get('id');
        $url='http://weixin.api.com/index.php/restful/add';
        $curl = new Curl();
        $aa=$curl->getCurl($url,'post',$data);
        var_dump($aa);
    }
}
