标签:dem   回调   ini   def   ade   jsapi   test   data   请求方法   

一、前期准备工作

1、微信公众号需要开通微信支付认证将获取的秘钥给三方平台

2、添加支付回调域名地址:填写三方平台域名地址即可(最多5个)

 

二、代码demo

1、完成支付类

<?php
/**

 * Time: 17:25
 */

namespace app\models;


class Payment
{

    public static function WxPayInit($body, $trade_no, $total_fee, $open_id, $notify_url, $attach = [])
    {

        $post_params = [
            ‘body‘ => $body,
            ‘trade_no‘ => $trade_no,
            ‘total_fee‘ => $total_fee * 100,
            ‘open_id‘ => $open_id,
            ‘attach‘ => $attach,
            ‘notify_url‘ => \Yii::$app->request->hostInfo . \Yii::$app->request->scriptUrl . $notify_url
        ];
        return self::WxPay($post_params);
    }

    public static function WxPay($data)
    {
        $hywx_test = \Yii::$app->params[‘hywx_test‘];
        $pay_config = [
            ‘APPID‘ => $hywx_test[‘app_id‘],
            ‘MCHID‘ => $hywx_test[‘mch_id‘],
            ‘MCHKEY‘ => $hywx_test[‘mch_key‘]
        ];

        $attach = json_encode($data[‘attach‘]);
        $input = new \WxPayUnifiedOrder();
        $input->SetBody($data[‘body‘]);
        $input->SetAttach($attach);
        $input->SetOut_trade_no($data[‘trade_no‘]);
        $input->SetTotal_fee($data[‘total_fee‘]);
        $input->SetTime_start(date("YmdHis"));
        $input->SetTime_expire(date("YmdHis", time() + 600));
        $input->SetNotify_url($data[‘notify_url‘]);
        $input->SetTrade_type("JSAPI");
        $input->SetOpenid($data[‘open_id‘]);
        $result = \WxPayApi::unifiedOrder($input, $pay_config);
        if ($result[‘result_code‘] == ‘SUCCESS‘ && $result[‘return_code‘] == ‘SUCCESS‘) {

            $jsapi = new  \WxPayJsApiPay();
            $jsapi->SetAppid($result["appid"]);
            $timeStamp = time();
            $jsapi->SetTimeStamp("$timeStamp");
            $jsapi->SetNonceStr(\WxPayApi::getNonceStr());
            $jsapi->SetPackage("prepay_id=" . $result[‘prepay_id‘]);
            $jsapi->SetSignType("MD5");
            $jsapi->SetPaySign($jsapi->MakeSign( $hywx_test[‘mch_key‘]));
            return $parameters = $jsapi->GetValues();
        }
    }
}

 

2、支付请求方法

require_once dirname(dirname(__FILE__)) . ‘/librarys/wx/wx_pay/lib/WxPay.Api.php‘;
require_once dirname(dirname(__FILE__)) . ‘/librarys/wx/wx_pay/lib/WxPay.Config.php‘;
require_once dirname(dirname(__FILE__)) . ‘/librarys/wx/wx_pay/lib/WxPay.NativePay.php‘;

    public function actionTest()
    {
        $body = ‘欧式body‘;
        $order_code = ‘HY‘ . date(‘YmdHis‘);
        $total_fee = 0.01;
        $open_id = ‘or-9g0kq0_p4FxCLMAWPg4ZPYX0k‘;//用户open_id
        $notify_url = ‘/site/test-call-back‘;//回调地址
        $jsApiParameters = Payment::WxPayInit($body, $order_code, $total_fee, $open_id, $notify_url);
        $return_arr = [];
        $return_arr[‘trade_no‘] = $order_code;
        $return_arr[‘jsApiParameters‘] = $jsApiParameters;
        return $this->renderJson($return_arr);
    }

3、支付页面

<?php
/**
 * Created by PhpStorm.
 * User: LiDingLie
 * Date: 2017/10/18 0018
 * Time: 11:28
 */

use yii\helpers\Url;

$web = Url::base();
$this->title = ‘订单支付‘;
$url = \app\librarys\Tools::urlBase();
?>

<a href="javascript:" onclick="pay()" class="zf_btn">确定支付</a>
<script type="text/javascript" src="<?= $web ?>/js/jweixin-1.0.0.js"></script>

<script type="text/javascript">

    function pay() {
        var baseUrl = ‘<?=$url?>‘;

        requestJson(baseUrl + ‘/site/test‘, {}, true, function (response) {
            if (response.status == 0) {
                trade_no = response.data.trade_no;
                var jsApiData = response.data.jsApiParameters;
//                var wechat = JSON.parse(jsApiData);
                callpay(jsApiData);
            } else {
                layer.msg(response.message);
            }
        });
    }


    function callpay(wechat) {
        if (typeof WeixinJSBridge == "undefined") {
            if (document.addEventListener) {
                document.addEventListener(‘WeixinJSBridgeReady‘, jsApiCall, false);
            } else if (document.attachEvent) {
                document.attachEvent(‘WeixinJSBridgeReady‘, jsApiCall);
                document.attachEvent(‘onWeixinJSBridgeReady‘, jsApiCall);
            }
        } else {
            jsApiCall(wechat);
        }
    }


    function pollCode(wechat) {
        var order_code = wechat.order_code;
        var data = {};
        data.order_code = order_code;
    }

    function jsApiCall(wechat) {
        WeixinJSBridge.invoke(‘getBrandWCPayRequest‘, {
            ‘appId‘: wechat.appId,
            ‘timeStamp‘: wechat.timeStamp,
            ‘nonceStr‘: wechat.nonceStr,
            ‘package‘: wechat.package,
            ‘signType‘: wechat.signType,
            ‘paySign‘: wechat.paySign
        }, function (res) {
            if (res.err_msg == ‘get_brand_wcpay_request:ok‘) {
                is_allow_pay = false;
//                js轮训查询 是否支付成功
                var setInt = setInterval(function () {
                    pollCode(wechat);
                }, 1000);

            } else if (res.err_msg == ‘get_brand_wcpay_request:cancel‘) {
                layer.msg(‘取消支付成功‘);

                //取消订单,作废报名记录
                cancelPayTicketHandler(wechat.order_code);
            } else {
                layer.msg(res.err_msg);
            }
        });
    }
</script>
