Editor to share with you the php version of how to develop UnionPay payment interface, I believe that most people do not know much about it, so share this article for your reference, I hope you can learn a lot after reading this article, let's go to know it!

UnionPay should first pay attention to two important parts:

The PHP operating environment is above 5.4.18.

Extended openssl is opened.

The columns in the development manual are for reference only, because they are basically wrong. You can try to go to a demo on the official website. Note that UnionPay is now developed. There is no test key provided, and it can only be developed in a formal environment.

Here is a payment class I wrote in ThinkPHP

/ * * UnionPay v0.1 * @ auther:Summer;* @ date:20151202* / class NetPayAction extends BaseAction {/ / in the class initialization method, introduce the relevant class library public function _ initialize () {header ("Content-type:text/html;charset=utf-8"); vendor ('Netpay.util.common', "," .php "); / / Import the encrypted core folder vendor (' Netpay.util.SecssUtil',", ".class.php") / / Import the encrypted core folder vendor ('Netpay.util.Settings_INI', "," .php "); / / import the encrypted core folder vendor (' Netpay.util.Settings',", ".php"); / / import the encrypted core folder $this- > securityPropFile= $_ SERVER ['DOCUMENT_ROOT'].
