本文实例讲述了php银联网页支付实现方法。分享给大家供大家参考。具体分析如下：这里介绍的银联WAP支付功能，仅限消费功能。
1. PHP代码如下：复制代码 代码如下:<?phpnamespace commonservices;class UnionPay{ /** * 支付配置 * @var array */ public $config = []; /** * 支付参数，提交到银联对应接口的所有参数 * @var array */ public $params = []; /** * 自动提交表单模板 * @var string */ private $formTemplate = <<<"HTML"<!DOCTYPE HTML><html><head> <meta charset="utf-8"> <title>支付</title></head><body> <div style="text-align:center">跳转中...</div> <form id="pay_form" name="pay_form" action="%s" method="post"> %s </form> <script type="text/javascript"> document.onreadystatechange = function(){ if(document.readyState == "complete") { document.pay_form.submit(); } }; </script></body></html>HTML;/*** 构建自动提交HTML表单* @return string*/public function createPostForm(){ $this->params["signature"] = $this->sign(); $input = ""; foreach($this->params as $key => $item) { $input .= " <input type="hidden" name="{$key}" value="{$item}">"; } return sprintf($this->formTemplate, $this->config["frontUrl"], $input);}/*** 验证签名* 验签规则：* 除signature域之外的所有项目都必须参加验签* 根据key值按照字典排序，然后用&拼接key=value形式待验签字符串；* 然后对待验签字符串使用sha1算法做摘要；* 用银联公钥对摘要和签名信息做验签操作* * @throws Exception* @return bool*/public function verifySign(){ $publicKey = $this->getVerifyPublicKey(); $verifyArr = $this->filterBeforSign(); ksort($verifyArr); $verifyStr = $this->arrayToString($verifyArr); $verifySha1 = sha1($verifyStr); $signature = base64_decode($this->params["signature"]); $result = openssl_verify($verifySha1, $signature, $publicKey); if($result === -1) { throw new Exception("Verify Error:".openssl_error_string()); } return $result === 1 ?
