yii2中自定义公共类

以微信企业号为例：

1、在YII根目录新建一个文件夹wechat，新建Wechat.php文件

代码如下：

<? 

namespace app\wechat;

class Wechat

{

    const AGENTID = 3;//应用ID

    const CORPID = "wx5d0183ad90c95d8b";//ID

    const CORPSECRET = "KTHAkkVl4mX4Jr_g89d3PXajYupsUcJFvGWQ1K6ZMagTPOh4kiNMfBLFoDr12DVh";//秘钥

    const SCOPE = "snsapi_base"; 

    const STATE = "123";    

  

    //自动登录跳转

    public function wxauto($jumpurl){   

        $corpid = self::CORPID; 

        $scope = self::SCOPE; 

        $state = self::STATE;  

        $url='https://open.weixin.qq.com/connect/oauth2/authorize?appid='.$corpid.'

        &redirect_uri='.urlencode($jumpurl).'

        &response_type=code&scope='.$scope.'&state='.$state.'#wechat_redirect';

        header("Location:".$url);

        exit;

    }

     

    //推送信息

    public function getPush($userid , $agentid , $message){

            $userinfo = $this->getToken();//获取access_token

            $access_token = $userinfo['access_token'];

            $sendmsg_url = "https://qyapi.weixin.qq.com/cgi-bin/message/send?access_token=".

            $access_token;

            $data="{\"touser\":\"$userid\",\"msgtype\":\"text\",\"agentid\":$agentid,\"text\":

            {\"content\":\"$message\"},\"safe\":0}";

            $res = $this->curlPost($sendmsg_url,$data);

            $errmsg=json_decode($res)->errmsg;

    }

     

    //获取token

    public function getToken(){     

        $corpid = self::CORPID; 

        $corpsecret = self::CORPSECRET; 

        $Url="https://qyapi.weixin.qq.com/cgi-bin/gettoken?corpid=".$corpid."&corpsecret=".$corpsecret;

        $res = $this->curlPost($Url);

        $access_token=json_decode($res)->access_token;

        $userinfo = array();

        $userinfo['access_token']=$access_token;

        return $userinfo;

    }

     

    //定义curl方法

    public function curlPost($url,$data=""){

        $ch = curl_init();

        $opt = array(

                CURLOPT_URL     => $url,

                CURLOPT_HEADER  => 0,

                CURLOPT_POST    => 1,

                CURLOPT_POSTFIELDS      => $data,

                CURLOPT_RETURNTRANSFER  => 1,

                CURLOPT_TIMEOUT         => 20

        );

        $ssl = substr($url,0,8) == "https://" ? TRUE : FALSE;

        if ($ssl){

            $opt[CURLOPT_SSL_VERIFYHOST] = 2; //注意1已经弃用

            $opt[CURLOPT_SSL_VERIFYPEER] = FALSE;

        }

        curl_setopt_array($ch,$opt);

        $data = curl_exec($ch);

        curl_close($ch);

        return $data;

    }

}

?>

　　

2、控制器的调用：

引入 use app\wechat\Wechat;

$chat = new Wechat();  //实例化类

$REDIRECT_URI= $_SERVER['HTTP_HOST'].'/test/back';//定义跳转URL

$chat->wxauto($REDIRECT_URI);//调用类的方法

    $chat->getToken();//调用类的方法

 

$corpid = Wechat::CORPID;//调用类的常量

$corpsecret = Wechat::CORPSECRET;//调用类的常量

$agentid=Wechat::AGENTID;//调用类的常量
