PHP accesses Alipay's instant payment function
这篇文章主要介绍了PHP 接入支付宝即时到账功能,非常不错，具有参考借鉴价值，需要的朋友可以参考下
首先请到支付宝那边申请一个及时到账的接口账户，需要提交相关材料申请。然后根据即时到账的API文档进行接入。API文档提供了各种语言版本的demo,我这里是下的php版demo,然后再进行相关修改操作。你也可以将demo版本的代码重新整合，我这里暂时为了走通充值及时到账流程，就不进行代码重构了。
前台表单提交
<form action="/pay/alipayapi.php" class="tm-panel-small uk-form uk-form-stacked" method="post" target="_blank">
<p class="element" style="margin-top:60px;">
</p>
<p class="uk-form-row">
<p class="uk-form-controls">
<label for="form-username" class="uk-form-label" style="display:inline-block;padding: 0 10px;vertical-align: middle;margin-left:-20px;">订单序号:</label>
<input class="uk-form-width-large" type="text" name="WIDout_trade_no" id="out_trade_no" value="<?php echo trim($_GET['orderid']);?>" >

<input class="uk-form-width-large" type="text" name="WIDsubject" value="<?php echo trim($_GET['orderid']);?>" >

</p>
</p>
<p class="uk-form-row">
<p class="uk-form-controls">

<input class="uk-form-width-large" type="text" name="WIDtotal_fee" value="<?php echo trim($_GET['amt']);?>">
<br>
</p>
</p>
<p class="uk-form-row">
<p class="uk-form-controls">
<label for="form-username" class="uk-form-label" style="display:inline-block;padding: 0 10px;vertical-align: middle;margin-left:-20px;">商品描述:</label>
<input class="uk-form-width-large" type="text" name="WIDbody" value="订单测试支付">
<br>
</p>
</p>
<input type="hidden" name="uid" value="<?php echo $_GET['uid'];?>">
<input type="hidden" name="codes" value="<?php echo $_GET['code'];?>">
<input type="hidden" name="tags" value="<?php echo $_GET['tag'] ?>">
<p class="uk-form-row">
<input class="uk-button uk-button-primary uk-button-large uk-width-1-1" type="submit" class="alisubmit" value ="确认支付">
</p>
</p>
</form>设置alipay.config.php配置文件,主要配置一下几个参数
$alipay_config['partner'] 设置签约账号ID
$alipay_config['key'] 设置MD5校验key
$alipay_config['notify_url'] 设置异步回调地址
$alipay_config['return_url'] 设置回调返回地址
$alipay_config['transport'] 设置协议类型，默认为http
$alipay_config['partner'] = 'xxxxxxxxxxxx'; //收款支付宝账号，以2088开头由16位纯数字组成的字符串，一般情况下收款账号就是签约账号 $alipay_config['seller_id'] = $alipay_config['partner']; // MD5密钥，安全检验码，由数字和字母组成的32位字符串，查看地址：https://b.alipay.com/order/pidAndKey.htm $alipay_config['key'] = 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'; // 服务器异步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问 $alipay_config['notify_url'] = "http://xx.xx.xx.xx/pay/notify_url.php"; // 页面跳转同步通知页面路径 需http://格式的完整路径，不能加?id=123这类自定义参数，必须外网可以正常访问 $alipay_config['return_url'] = "http://xx.xx.xx.xx/pay/return_url.php"; //签名方式 $alipay_config['sign_type'] = strtoupper('MD5'); //字符编码格式 目前支持 gbk 或 utf-8 $alipay_config['input_charset']= strtolower('utf-8'); //ca证书路径地址，用于curl中ssl校验 //请保证cacert.pem文件在当前文件夹目录中 $alipay_config['cacert'] = getcwd().'\\cacert.pem'; //访问模式,根据自己的服务器是否支持ssl访问，若支持请选择https；若不支持请选择http $alipay_config['transport'] = 'http'; // 支付类型 ，无需修改 $alipay_config['payment_type'] = "1"; // 产品类型，无需修改 $alipay_config['service'] = "create_direct_pay_by_user";
交易处理完成后会发送订单信息及交易状态到你指定好的回传return_url.php中，你可以通过回传给你的订单状态判断交易是否成功，成功则进入下一步逻辑（你自己的订单处理逻辑），否则返回失败。

Explain JSON Web Tokens (JWT) and their use case in PHP APIs.
Apr 05, 2025 am 12:04 AM
JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
How does session hijacking work and how can you mitigate it in PHP?
Apr 06, 2025 am 12:02 AM
Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
What are Enumerations (Enums) in PHP 8.1?
Apr 03, 2025 am 12:05 AM
The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.
Describe the SOLID principles and how they apply to PHP development.
Apr 03, 2025 am 12:04 AM
The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.
