Smart Pay Payment access experience

Recently in the making of an advertising platform, the need to use UnionPay payment, customers have chosen to pay the third-party platform.

General wisdom to pay the background need to bind online site domain name, so test payment, must be online on the server.

I first download the development document, in fact, the demo file can be used directly,

Then use CMD to generate the public and private keys to upload it to the payment background, update the public key.

The latest public and private keys are also updated in the code.

If the signature fails when the connection occurs, the key should be the other problem, need to carefully detect the code.

Successful access will jump to the third-party payment platform.
