doyo 微信手机端自动登录和绑定openid

reg.html 和 login.html

<input type="hidden" name="openid" value="{$_GET['openid']}">

底部js判断自动获取openid

<script>

//判断是否是微信浏览器的函数
function iswx(){
  //window.navigator.userAgent属性包含了浏览器类型、版本、操作系统类型、浏览器引擎类型等信息，这个属性可以用来判断浏览器类型
  var ua = window.navigator.userAgent.toLowerCase();
  //通过正则表达式匹配ua中是否含有MicroMessenger字符串
  if(ua.match(/MicroMessenger/i) == 'micromessenger'){
  return true;
  }else{
  return false;
  }
}

    $(function(){
        // 判断微信浏览
        openid = '{$_GET['openid']}';
        console.log(iswx());
        if(iswx() && !openid){
              window.location.href="index.php?a=wxlogin&m=login";
        }
    })
</script>

index.php 里面加俩函数用来 获取openid

 function wxlogin(){
        $appid='wx1fc44448137cb1';
        $redirect_rui=urlencode('http://13.jianku.com.cn/index.php?&a=wxlogin2&m='.$this->syArgs("m",1));
        $url='https://open.weixin.qq.com/connect/oauth2/authorize?appid='.$appid.'&redirect_uri='.$redirect_rui.'&response_type=code&scope=snsapi_userinfo&state=asd123#wechat_redirect';
        header('Location:'.$url);
    }
    function wxlogin2(){
        $appid='wx1fc4444437cb1';
        $appsecret='02286028tttt88cbb5cdbdc3471';
        $code=$_GET['code'];
        $url='https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code';
        $result=file_get_contents($url);
        $result=json_decode($result,true);
        $access_token=$result['access_token'];
        $openid=$result['openid'];


        // 查询是否已经绑定过，绑定过直接登录    
            $conditions = array('token' => $openid);
            $m = syDB('member')->find($conditions,null,'id,user,token');
            if($m){
                $_SESSION['member'] = array(
                    'user' => $m['user'],
                    'id' => $m['id'],
                    'gid' => $r['gid'],
                );
                $this->gourl='?c=member';
                jump($this->gourl);
            }
            else
            {
                // 没有绑定过，新注册或者绑定已注册账号

                // 默认到注册页面
                jump("index.php?c=member&a=".$this->syArgs("m",1)."&openid=".$openid);

            }


    }

member.php 更新数据库绑定用户的openid

login()

// 登录绑定openid
if($this->syArgs("openid",1)) syDB('member')->update(array('id'=>$r['id']),array('token'=>$this->syArgs("openid",1)));

// 手机登录微信

        $this->gourl='?c=article&id='.$this->syArgs('id');
        jump($this->gourl);
