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

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
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($list);exit;
include template('xxx', 'xxx', 'default');
}
4.前台页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta http-equiv="content-type" content="text/html;charset=utf-8"/>
<meta name="viewport" content="width=device-width, initial-scale=1"/>
<title>支付</title>
<script type="text/javascript">
//调用微信JS api 支付
function jsApiCall() {
WeixinJSBridge.invoke(
'getBrandWCPayRequest',
{$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
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();
$notify->Handle(false);
6.微信支付扫码支付(接口)
public function jsapi()
{
include PHPCMS_PATH . '/wxpay/lib/WxPay.Api.php';
include PHPCMS_PATH . '/wxpay/WxPay.JsApiPay.php';
include PHPCMS_PATH . '/wxpay/WxPay.NativePay.php';
include PHPCMS_PATH . '/wxpay/log.php';
if ($_POST['user_name'] && $_POST['amount'] && $_POST['title'] && $_POST['user_id']) {
$order_sn = date("YmdHis") . substr(time(), -3) . str_pad(mt_rand(1, 9999999), 7, '0', STR_PAD_LEFT);
$order['order_sn'] = $order_sn;
$order['amount'] = $_POST['amount'];
$order['user_phone'] = $_POST['user_phone'];
$order['user_id'] = $_POST['user_id'];
$order['source'] = $_POST['source'];
$order['user_address'] = $_POST['user_address'];
$order['user_name'] = $_POST['user_name'];
$order['cate_name'] = $_POST['title'];
$order['cate_id'] = 101;
$order['c_time'] = time();
$re = 1;
if ($re) {
$notify = new NativePay();
$input = new WxPayUnifiedOrder();
$input->SetBody($_POST['title']);
$input->SetAttach($_POST['title']);
$input->SetOut_trade_no($order_sn);
$input->SetTotal_fee($_POST['amount'] * 100);
$input->SetTime_start(date("YmdHis"));
$input->SetTime_expire(date("YmdHis", time() + 600));
$input->SetGoods_tag("xxxx");
$input->SetNotify_url("http://www.xxxx.com/wxpay/notify.php");
$input->SetTrade_type("NATIVE");
$input->SetProduct_id(time());
$result = $notify->GetPayUrl($input);
$url = $result["code_url"];
$url = $result["code_url"];
}
}
