php版银联支付接口开发简明教程

本文实例讲述了php版银联支付接口开发的方法。分享给大家供大家参考，具体如下：

支付接口现在有第三方的支付接口也有银行的支付接口。这里就来介绍php版本银联支付接口开发的方法。

银联支付，首先要注意二重要的部分：

PHP运行环境是5.4.18以上

开了扩展openssl

开发手册上面的列子只做参考，因为基本都是错的。你可以试着去官网下一个demo。。。注意现在银联开发，没有测试密钥提供，只能在正式环境开发

下面是我用ThinkPHP编写的一个支付类

/**
* 银联支付 v0.1

class NetPayAction extends BaseAction{
//在类初始化方法中，引入相关类库

public function pgReturn(){

   foreach($_POST as $key=>$value){
     $text[$key] = urldecode($value);
   }
  if ($secssUtil->verify($text)) {
           //支付成功
    $_SESSION["VERIFY_KEY"] = "success";
  } else {
   //支付失败

  }
 }
 }
}
}

银联支付应该是算比较简单的！！

希望本文所述对大家PHP程序设计有所帮助。
