php thinkPHP和onethink微支付插件

thinkPHP和微支付实现的微信支付插件，在微信中调用微信jssdk实现支付，这里有详细的代码和教程，具体看这里：http://vote.wucheshuedu.com/index.php?s=/Home/Article/detail/id/20.html``` php //实现的Wxpay钩子方法 public function Wxpay($param){ require './Addons/Wxpay/WxPayPubHelper/WxPayPubHelper.php'; $jsApi = new \JsApi_pub();

        //=========步骤1：网页授权获取用户openid============
        if (!isset($_GET['code']))
        {
            //触发微信返回code码
            $url = $jsApi->createOauthUrlForCode(\WxPayConf_pub::JS_API_CALL_URL.'/order_id/'.$param['order_id']);
            Header("Location: $url");
        }else
        {
            $order_id = $param['order_id'];
            $info = M('Order')->where('id='.$order_id)->find();
            if(empty($info) || $info['is_pay'] == 1){
                dump('该订单不存在或已支付'.$order_id);
                exit();
            }
            $this->assign('info', $info);
            $a = $info['money'];
            $b = 100;
            $c = $a * $b;

            //获取code码，以获取openid
            $code = $_GET['code'];
            $jsApi->setCode($code);
            $openid = $jsApi->getOpenId();
        }

        //=========步骤2：使用统一支付接口，获取prepay_id============
        //使用统一支付接口
        $unifiedOrder = new \UnifiedOrder_pub();

        $unifiedOrder->setParameter("openid","$openid");//商品描述
        $unifiedOrder->setParameter("body","在线预订");//商品描述
        //自定义订单号，此处仅作举例
        $timeStamp = time();

// $out_trade_no = \WxPayConf_pub::APPID."$timeStamp"; $out_trade_no = $info['ordersn']; $unifiedOrder->setParameter("out_trade_no", "$out_trade_no");//商户订单号 $unifiedOrder->setParameter("total_fee", "$c");//总金额 $unifiedOrder->setParameter("notify_url",\WxPayConf_pub::NOTIFY_URL.'/order_id/'.$param['order_id']);//通知地址 $unifiedOrder->setParameter("trade_type","JSAPI");//交易类型

        $prepay_id = $unifiedOrder->getPrepayId();
        //=========步骤3：使用jsapi调起支付============
        $jsApi->setPrepayId($prepay_id);
        $jsApiParameters = $jsApi->getParameters();
        $this->assign('jsApiParameters', $jsApiParameters);

        $this->display('pay');
    }
