利用PHP的反射把两种支付接口统一起来。

使用前需要配置目录下的Config文件即WxpayConfig.php与AlipayConfig.php

使用支付宝支付

<?phpnamespace WatcherHangzhouPayment\Payment;$payRequestParams = array(    'returnUrl' => $this->generateUrl('pay_return', array('name' => 'alipay'), true),    'notifyUrl' => $this->generateUrl('pay_notify', array('name' => 'alipay'), true),    'showUrl' => $this->generateUrl('show_goods', array('id' => $goods['id']), true),);$paymentRequest = createPaymentRequest($order, $requestParams);function createPaymentRequest($order, $requestParams){    $requestParams = array_merge($requestParams, array(            'orderSn' => $order['sn'],            'title' => $order['title'],            'summary' => '',            'amount' => $order['amount'],    ));    return Payment::createRequest('alipay', $requestParams);}$htmlForm = $request->form();$inputHtml = '';foreach ($htmlForm['params'] as $key => $value) {    $inputHtml .= "<input type=\"hidden\" name=\"{$key}\" value=\"{$value}\">";}$html = <<<EOF<!DOCTYPE html><html><head>  <meta charset="utf-8">  <title>Jumping to alipay gateway...</title><body>  <form action="{$htmlForm['action']}"  method="{$htmlForm['method']}" name="form">    {$inputHtml}  </form>  <script>    document.all.form.submit();  </script></body></html>EOF;echo $html;die;

使用微信支付

微信支付依赖composer的把url转换为二维码text的Endroid\QrCode\QrCode库。

<?phpnamespace WatcherHangzhouPayment\Payment;<?phpnamespace WatcherHangzhouPayment\Payment;$payRequestParams = array(    'returnUrl' => $this->generateUrl('pay_return', array('name' => 'wxpay'), true),    'notifyUrl' => $this->generateUrl('pay_notify', array('name' => 'wxpay'), true),    'showUrl' => $this->generateUrl('show_goods', array('id' => $goods['id']), true),);$paymentRequest = createPaymentRequest($order, $requestParams);function createPaymentRequest($order, $requestParams){    $requestParams = array_merge($requestParams, array(            'orderSn' => $order['sn'],            'title' => $order['title'],            'summary' => '',            'amount' => $order['amount'],    ));    return Payment::createRequest('wxpay', $requestParams);}$returnXml = $paymentRequest->unifiedOrder();$returnArray = $paymentRequest->fromXml($returnXml);if ($returnArray['return_code'] == 'SUCCESS') {    $url = $returnArray['code_url'];    $html = <<<EOF<!DOCTYPE html><html><head>  <meta charset="utf-8">  <title>使用微信二维码支付</title><body>  <img  src="{{ path('generate_qrcode_image',{url:url}) }}"  alt="微信支付与支付宝支付整合 PHP实现" >          <div class="text-qrcode hidden-xs">            请使用微信扫一扫<br>扫描二维码支付          </div></body></html>EOF;    echo $html;    die;}

回调数据处理

if (支付宝) {    $response = Payment::createResponse('alipay', $_POST);} elseif (微信) {    $returnXml = $GLOBALS['HTTP_RAW_POST_DATA'];    $response = Payment::createResponse('wxpay', fromXml($returnXml));}$payData = $response->getPayData();if ($payData['status'] == "success") {    //干支付成功该干的事情}function fromXml($xml){    $array = json_decode(json_encode(simplexml_load_string($xml, 'SimpleXMLElement', LIBXML_NOCDATA)), true);    return $array;}

Dependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Dependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
