这篇文章主要介绍了php银联网页支付实现方法,实例分析了php操作银联网支付接口的技巧,具有一定参考借鉴价值,需要的朋友可以参考下

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:

namespace common\services;
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 =


   
    支付


   
跳转中...

   

        %s

* @return string
*/

{
        $this->params['signature'] = $this->sign();
        $input = '';
        foreach($this->params as $key => $item) {
            $input .= "\t\t\n";
        }
        return sprintf($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
*/
