PHPcms微信支付

基本上按照官方给的sdk修改的没有改动太多东西
微信支付有些麻烦需要在微信公众平台上设置-支付授权目录（重要）和-[网页授权获取用户基本信息]（重要）
流程已经走通因为各个项目的不同仅供参考吧

有好的建议请留言

1.去官网下载

https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

2.重新建立目录结构

3.在模块方法中建立方法

注微信支付中获取code和openid时容易丢失传递值可以考虑cookie传值

[php] view plain copy

public function wx_pay() {

    include PHPCMS_PATH . '/wxpay/lib/WxPay.Api.php';

    include PHPCMS_PATH . '/wxpay/WxPay.JsApiPay.php';

    include PHPCMS_PATH . '/wxpay/log.php';

    $logHandler = new CLogFileHandler(PHPCMS_PATH . "'/wxpay/logs/" . date('Y-m-d') . '.log');

    $log = Log::Init($logHandler, 15);

    //①、获取用户openid

    $tools = new JsApiPay();

    $openId = $tools->GetOpenid();

    $list['cate_name'] = param::get_cookie('cate_name');

    $list['amount'] = param::get_cookie('amount');

    $list['order_sn'] = param::get_cookie('order_sn');

    //②、统一下单

    $input = new WxPayUnifiedOrder();

    $input->SetBody($list['cate_name']);

    $input->SetAttach($list['cate_name']);

    $input->SetOut_trade_no($list['order_sn']);

    $input->SetTotal_fee($list['amount'] * 100);

    $input->SetTime_start(date("YmdHis"));

    $input->SetTime_expire(date("YmdHis", time() + 600));

    $input->SetGoods_tag("test");

    $input->SetNotify_url("http://www.www.com/wxpay/notify.php");

    $input->SetTrade_type("JSAPI");

    $input->SetOpenid($openId);

    $order = WxPayApi::unifiedOrder($input);

    $list['jsApiParameters'] = $tools->GetJsApiParameters($order);

    //var_dump($list);exit;

    include template('xxx', 'xxx', 'default');

}

4.前台页面

[html] view plain copy

<!DOCTYPE html>

<html lang="en">



<head>

    <meta http-equiv="content-type" content="text/html;charset=utf-8"/>

    <meta name="viewport" content="width=device-width, initial-scale=1"/>

    <title>支付</title>

    <script type="text/javascript">

        //调用微信JS api 支付

        function jsApiCall() {

            WeixinJSBridge.invoke(

                'getBrandWCPayRequest',

                {$list[jsApiParameters]},

                function(res) {

                    WeixinJSBridge.log(res.err_msg);

                    if (res.err_msg == "get_brand_wcpay_request:ok") {

                        window.location.href = "";

                    } else {

                        //返回跳转到订单详情页面

                        alert(支付失败);

                        window.location.href = "";

                    }

                }

            );

        }



        function callpay() {

            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();

            }

        }

    </script>

</head>



<body>

    <div class="receive">

        <h2>微信支付</h2>

        <ul class="form-list">



            <p class="submit" type="button" onclick="callpay()">立即支付</p>

        </ul>

    </div>

</body>



</html>

5.回调函数

经测试回调链接不支持拼接链接因为赶时间没有进行其他的实现方法
回调函数 /wxpay/notify.php

[php] view plain copy

<?php



ini_set('date.timezone','Asia/Shanghai');

error_reporting(E_ERROR);

require_once "lib/WxPay.Api.php";

require_once 'lib/WxPay.Notify.php';

require_once 'log.php';



//初始化日志

$logHandler= new CLogFileHandler("logs/".date('Y-m-d').'.log');

$log = Log::Init($logHandler, 15);



class PayNotifyCallBack extends WxPayNotify

{

function __construct()

{



    // $hostname = "localhost";

    // $database = "cmsv";

    // $username = "root";

    // $password = "root";





    $conn = mysql_connect($hostname, $username, $password) or trigger_error(mysql_error(),E_USER_ERROR);

    mysql_select_db($database, $conn);

}

//查询订单

public function Queryorder($transaction_id)

{

    $input = new WxPayOrderQuery();

    $input->SetTransaction_id($transaction_id);

    $result = WxPayApi::orderQuery($input);

    Log::DEBUG("query:" . json_encode($result));

    if(array_key_exists("return_code", $result)

        && array_key_exists("result_code", $result)

        && $result["return_code"] == "SUCCESS"

        && $result["result_code"] == "SUCCESS")

    {

        return true;

    }

    return false;

}



//重写回调处理函数

public function NotifyProcess($data, &$msg)

{

    Log::DEBUG("call back:" . json_encode($data));

    $notfiyOutput = array();



    if(!array_key_exists("transaction_id", $data)){

        $msg = "输入参数不正确";

        return false;

    }

    //查询订单，判断订单真实性

    if(!$this->Queryorder($data["transaction_id"])){

        $msg = "订单查询失败";

        return false;

    }

    $order_sn = $data["out_trade_no"];

            $transaction_id = $data["transaction_id"];

    $amount = $data["total_fee"]/100;

    $query = "SELECT ...";

    $result = mysql_query($query);

    $row = mysql_fetch_array($result);

    $time = time();

    Log::DEBUG("v2_code_order:" . json_encode($row));

    if($amount == $row['amount']){

        $sql2 = "SELECT id,code_sn FROM ...";

        $re = mysql_query($sql2);

        $code = mysql_fetch_array($re);

        Log::DEBUG("code_ll:" . json_encode($code));

        $sql_code="UPDATE v2_code SET..";

        $code_up = mysql_query($sql_code);



        $sql_order="UPDATE v2_code_order SET ...'";

        $order_up = mysql_query($sql_order);

        Log::DEBUG("code_up:" . json_encode($code_up));

        Log::DEBUG("order_up:" . json_encode($order_up));



    }else{

        return false;

    }





    return true;

}

}



Log::DEBUG("begin notify");

$notify = new PayNotifyCallBack();

$notify->Handle(false);
