This article mainly introduces the development of the php version of the Alipay service window API interface. Interested friends can refer to it. I hope to be helpful.
The development of the Alipay service window API interface is very important for many friends who want to recharge on the website. Today we will take a look at an example of the development of the PHP version of the Alipay service window API interface.
I have nothing to do in the past two days to access the Alipay service window. Look at Alipay's DEMO. Oh my God, how can I evaluate it? The readability is not very good and it hinders simple development. So I simply developed it based on the API provided. There are still many imperfections in the interface. If you are interested, you can improve it yourself. I will post the code below, and I will write how to use it when I have time.

}Okay, the above is an example of the development of the Alipay service window API interface compiled by the editor for you. The prerequisite for this is that we must apply for a permission. This official can apply to the editor I won’t introduce it.
