This article mainly introduces the example analysis of the callback operation of the thinkPHP framework docking Alipay instant arrival interface. The article is very detailed and has a certain reference value. Interested friends must finish reading it!

The details are as follows:

With regard to the docking process of the Alipay instant collection interface, it is very simple, and many people have sent it. I am no longer verbose here. After the docking is completed, the callback after the success of online payment is relatively difficult. I'll focus on sharing my experience.

When I was developing the second-generation tourism CMS (http://www.erdaicms.com)), I also spent a lot of time in the callback.

Whether it is Alipay interface or WeChat Pay interface, callback is divided into jump callback and asynchronous notification callback. Jump callback is not safe. If you join the guest and close the payment page immediately after the payment is completed, you will not be notified that this order has been paid, so we need to use asynchronous notification callback:

$alipay_config ['notify_url'] = ". $ss [' web_url']." / v.php/Index-alipay_notify_url.html "

First set the address that introduces the asynchronous callback

The specific handling function of asynchronous callback is also posted here for reference:

Because it is an asynchronous notification, debugging is troublesome and cannot be obtained by WYSIWYG. That is to say, generally speaking, there is no way to print the output result with echo or print_r, and there is no way to know where it is executed or the result. At this time, we use log file output, code:

$file ='. / log.txt';// the file name to write to (can be any file name). If the file does not exist, it will create a $content = "paid successfully". $bdata ['total_fee']. "\ n"; / / the content to be written file_put_contents ($file, $content,FILE_APPEND); / / write to the file

The above code automatically generates a log.txt file in the root directory, so that you can easily know the execution result and facilitate debugging.

Alipay's asynchronous notification interface will notify you many times until you return success, that is, if you submit a test order, you can test it many times, because if you do not return success, it will notify you at regular intervals.
