微信支付开发-支付工厂H5Api查账代码

一、H5支付产品、Native支付产品

二、工厂父类抽象类代码开发

<?php
/**
 * 微信父类抽象类
 * User: 龙哥·三年风水
 * Date: 2024/9/19
 * Time: 11:33
 */
namespace Payment\WechatPay;
abstract class WechatPaymentHandle
{
    /**
     * 下单
     * User: 龙哥·三年风水
     * Date: 2024/9/19
     * Time: 11:36
     * @ return mixed
     */
    protected abstract function pay();

    /**
     * 查询
     * User: 龙哥·三年风水
     * Date: 2024/9/19
     * Time: 11:39
     * @ return mixed
     */
    protected abstract function transac();

    /**
     * 退款
     * User: 龙哥·三年风水
     * Date: 2024/9/19
     * Time: 11:42
     * @ return mixed
     */
    protected abstract function refunds();
}

三、工厂通道选择类代码开发

<?php

四、H5Api支付产品查账代码开发

<?php
/**
 * H5支付方式

 * Time: 11:29
 */
namespace Payment\WechatPay\impl;

            $error['code'] = $arr['code'];
            $error['message'] = $arr['message'];
            $error['timestamp'] = time();
            $error['ip'] = get_client_ip();

        }
        return $arr;
    }

    /**

    public function __destruct(){
        $this->url = '';
        $this->header = '';
        $this->data = [];
    }
}

五、微信支付订单号查询订单测试调用

public function index(){
        //定义参数
        $transaction_id = '支付时返回微信订单号';
        // 初始化通道
        $wechatPaymentFactory = new WechatPaymentFactory(3);
        // 选择实例
        $wechatPaymentHandle = $wechatPaymentFactory->sendWechatPaymentHandle("https://api.mch.weixin.qq.com/v3/pay/transactions/id/{$transaction_id}",'');
        $res = $wechatPaymentHandle->pay();
        var_dump($res);
}

六、商户订单号查询订单测试调用

public function index(){
        //定义参数
        $out_trade_no = '支付时系统创建的支付单号';
        // 初始化通道
        $wechatPaymentFactory = new WechatPaymentFactory(3);
        // 选择实例
        $wechatPaymentHandle = $wechatPaymentFactory->sendWechatPaymentHandle("https://api.mch.weixin.qq.com/v3/pay/transactions/out-trade-no/{$out_trade_no}",'');
        $res = $wechatPaymentHandle->pay();
        var_dump($res);
}
