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 ：http://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&timestamp=%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。
