PHP微信支付功能示例

本文实例讲述了PHP微信支付功能。分享给大家供大家参考，具体如下：

微信开发SDK:文中用的是php_sdk_v3.0.9 ：https://pay.weixin.qq.com/wiki/doc/api/jsapi.php?chapter=11_1

import("wxpay.lib.AppPay#Config", EXTEND_PATH, ".php");
import("wxpay.lib.WxPay#Api", EXTEND_PATH, ".php");
//$this->weixinpay();
$config = new \AppPayConfig();
//订单号
$appId = $config->GetAppId();
$key = $config->GetKey();
$money = 0.01 * 100;
$orderSn = 'M201810241754107557';//订单号;
$curTime = time();
$input = new \WxPayUnifiedOrder();
$input->SetBody("用户红包");
$input->SetOut_trade_no($orderSn);
$input->SetTotal_fee($money);
$input->SetTrade_type("APP");
$unifiedOrder = \WxPayApi::unifiedOrder($config, $input);
if ($unifiedOrder['result_code'] == 'SUCCESS' && $unifiedOrder['return_code'] == 'SUCCESS') {
  /*$unifiedOrder 组成：
   * ["appid"] => string(18) "wx2xxxx49"
  ["mch_id"] => string(10) "1xxxxxx01"
  ["nonce_str"] => string(16) "1GnEUXTuTcFtJVtb"
  ["prepay_id"] => string(36) "wx241933xxx68fa24ece70611692955"
  ["result_code"] => string(7) "SUCCESS"
  ["return_code"] => string(7) "SUCCESS"
  ["return_msg"] => string(2) "OK"
  ["sign"] => string(32) "7903xxxxx4710E460CB156"
  ["trade_type"] => string(3) "APP"*/
  $curTime = time();
  // 第一部分
  $wxpayResult = new \WxPayResults();
  $wxpayResult->SetData('appid', $unifiedOrder['appid']);
  $wxpayResult->SetData('partnerid', $unifiedOrder['mch_id']);
  $wxpayResult->SetData('prepayid', $unifiedOrder['prepay_id']);
  $wxpayResult->SetData('noncestr', $unifiedOrder['nonce_str']);
  $wxpayResult->SetData('timestamp',$curTime);
  $wxpayResult->SetData('package',"Sign=WXPay");
  $wxpayResult->SetData('sign',"");
  $wxpayResult->SetSign($config);
  $data = $wxpayResult->GetValues();
  // 第二部分
  $data['appid'] = $unifiedOrder['appid'];
  $data['partnerid'] = $unifiedOrder['mch_id'];
  $data['prepayid'] = $unifiedOrder['prepay_id'];
  $data['noncestr'] = $unifiedOrder['nonce_str'];;
  $data['timestamp'] = $curTime;
  $data['package'] = "Sign=WXPay";
  $data['sign'] = $this->wxappPaySign($key, $data);//$unifiedOrder['sign'];//签名,具体签名方案参见微信公众号支付帮助文档;
  $this->returnSuccess($data);
} else {
  Log::write(var_export($unifiedOrder, true));
  $this->returnError(300, '微信支付失败');
}
private function wxappPaySign($key,$parameters)
{
  $sign = md5(sprintf("appid=%s&noncestr=%s&package=%s&partnerid=%s&prepayid=%s×tamp=%s&key=%s",
    $parameters['appid'],
    $parameters['noncestr'],
    $parameters['package'],
    $parameters['partnerid'],
    $parameters['prepayid'],
    $parameters['timestamp'],
    $key));
  return strtoupper($sign);
}

第一部分和第二部分功能是相同的。
