How to use ThinkPHP6 to implement Alipay payment

With the popularity of mobile payment, Alipay has become the preferred payment method for more and more people. As a high-performance, high-efficiency, safe and stable open source framework, ThinkPHP6 is also favored by many developers. So, how to implement Alipay payment quickly and easily in ThinkPHP6?

First of all, we need to apply to sign the Alipay Open Platform on the Alipay Open Platform and obtain the corresponding application information. For specific procedures, please refer to the official documentation of Alipay Open Platform.

Next, install Alipay SDK in ThinkPHP6. You can execute the following command in the root directory of ThinkPHP6:

composer require "alipay/easysdk:dev-master" -vvv

After successful installation, create a new AliPay folder in the app directory, then create the Service directory under the folder, and then create PayService.php in the directory. Used to encapsulate Alipay payment interface calls:

<?php

namespace appliPayservice;

use Exception;
use thinkacadeConfig;
use thinkacadeLog;
use AlipayEasySDKKernelFactory;
use AlipayEasySDKPaymentCommonModelsAlipayTradeAppPayModel;

class PayService
{
    /**
     * app支付
     *
     * @param integer $orderId 订单ID
     * @param string $subject 订单标题
     * @param string $body 订单内容
     * @param float $amount 订单金额（元）
     * @param bool $isDebug 是否开启调试
     * 
     * @return array|string
     */
    public function appPay($orderId, $subject, $body, $amount, $isDebug = false)
    {
        try {
            // 获取支付宝配置信息
            $config = Config::get('alipay.');

            // 加载SDK配置
            Factory::setOptions($config);

            // 创建支付请求对象
            $request = Factory::payment()->appPay(new AlipayTradeAppPayModel([
                'outTradeNo' => $orderId, // 订单ID
                'subject' => $subject, // 订单标题
                'totalAmount' => strval($amount), // 订单金额（元）
                'body' => $body, // 订单内容
            ]));

            // 返回支付参数
            return $request;
        } catch (Exception $e) {
            // 异常处理，自行根据业务逻辑实现
            Log::error($e->getMessage());
            return '支付请求失败，请重新尝试';
        }
    }
}

Note that the payment methods here are for reference only, and the specific parameter configuration can be adjusted according to your own business needs.

Finally, call PayService in the controller to implement the Alipay payment function:

<?php

namespace appindexcontroller;

use thinkacadeRequest;
use appliPayservicePayService;

class Index
{
    public function index()
    {
        // 生成订单
        $orderId = 1;
        $subject = '测试订单';
        $body = '测试订单内容';
        $amount = 0.01;

        $payService = new PayService();
        $payParams = $payService->appPay($orderId, $subject, $body, $amount, true);

        // 返回支付参数给客户端
        return json($payParams);
    }
}

The above are the basic steps for using ThinkPHP6 to implement Alipay payment. Of course, corresponding logical processing and exception handling are also required in actual applications to meet specific business needs.

In general, with the powerful functions of Alipay SDK and ThinkPHP6, it has become extremely simple to implement Alipay payment, and the wide application of Alipay payment also provides us with important information to develop more convenient and faster mobile payment applications. Support and security.
