thinkphp与微信jssdk结合分享实例
新建commoncontroller.class.php来获取
appid: '', // 必填，公众号的唯一标识
timestamp: , // 必填，生成签名的时间戳
noncestr: '', // 必填，生成签名的随机串
signature: '',// 必填，签名getsignpackage();
        $this->assign('signpackage',$signpackage);
    }
}
//微信方法

    }
}下面就可以使用了
新建indexcontroller.class.phpdisplay();
    }
}html文件中添加
        之后就大功告成
