PHP method to implement WeChat refund application process
This article mainly introduces you to the php implementation of the WeChat refund application process. It is implemented using the refund() method provided in WxPay.Api.php, the most important class file in the official SDK. Please refer to it for complete reference. Below is this article, I hope it can help everyone.
Of course, WeChat payment has been settled, otherwise how can I get a refund? This time I will use the official demo. Of course, there may be many masters on the Internet who have rewritten and encapsulated the demo themselves, which may be easier to use and simpler, but I still don’t recommend using it for the following reasons:
(1) It may not be fully functional, maybe it just implements WeChat payment , but there are also business functions such as applying for refunds, querying refunds, order inquiries, and canceling orders, which you may need later. If you rely on the convenience of the master’s SDK, you will be confused if there are new business needs;
(2) Security considerations, when it comes to payment and money, it must be very safe. Although I also complain about the official SDK, at least it will be relatively safe. It will be rewritten again. Although no problems have been found for the time being, it will be bad if there are loopholes.
This article is still implemented by using the refund() method provided in WxPay.Api.php, the most important class file in the official SDK. This method is located at No. 141 of the WxPay.Api.php file. OK, the code is as follows:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 |
|
The official method is very clear about what parameters are required, and there are some required parameters that the SDK has completed for us. I will use this method Re-encapsulate it to make it easier to call in the project:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 |
|
I need to complain here, but I don’t even mention the type of the return value. When paying, XML data is returned. Here What was returned was an array, which caught me off guard. Haha, but it is better to return an array, so I can directly judge and process it.
The method call is even simpler:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
|
The successful return of the refund is as follows:
Personal test is correct: This is implemented by integrating the official SDK. If you do not use the SDK, you can use a simpler method, see: PHP to implement WeChat payment (jsapi payment) and refund (no need to integrate the payment SDK)
