具体代码如下

namespace Payment\Controller;

use Common\Controller\FrontbaseController;

class WxpayController extends FrontbaseController{

//api--获取的订单号

public function wechatPay(){

require_once C(EXTEND_PATH).'/Wxpay/WechatAppPay.php';

$appid = 'wx************';

$mch_id = '**商户id**';

$notify_url = 'http://**********/application/Payment/notify.php';

$key = '*******商户秘钥*********';

$description = I("description");//商品描述

$wxPrice = I("wxPrice"); //订单金额 只能为整数 单位为分

$tradeNo = I("tradeNo"); //自定义的订单号

//1.统一下单方法

$wechatAppPay = new \WechatAppPay($appid, $mch_id, $notify_url, $key);

$params['body'] = $description; //商品描述

$params['out_trade_no'] = $tradeNo; //自定义的订单号

$params['total_fee'] = $wxPrice; //订单金额 只能为整数 单位为分

$params['trade_type'] = 'APP'; //交易类型 JSAPI | NATIVE | APP | WAP

$result = $wechatAppPay->unifiedOrder( $params );

//print_r($result); // result中就是返回的各种信息信息，成功的情况下也包含很重要的prepay_id

//2.创建APP端预支付参数

/** @var TYPE_NAME $result */

$data = @$wechatAppPay->getAppPayParams( $result['prepay_id'] );

// 根据上行取得的支付参数请求支付即可

if($data){

$arr['status'] = 1;

$arr['appid'] = $data['appid']; //应用APPID

$arr['partnerid'] = $data['partnerid']; //商户号

$arr['prepayid'] = $data['prepayid']; //预支付交易会话标识

$arr['package'] = $data['package']; //交易类型

$arr['noncestr'] = $data['noncestr']; //微信返回的随机字符串

$arr['timestamp'] = $data['timestamp']; //时间戳

$arr['sign'] = $data['sign']; //微信返回的签名

}else{

$arr['status'] = 0;

$arr['msg'] = '获取微信返回信息失败';

}

$this->output($arr);

}

}
