1. The notify_url address in Wechat native Mode 2 must be a public network address.

two。 Alipay's notify_url cannot be in the form of query string, such as xxx/notify.php? Route=a/b, can only be xxx/notify.php

In the synchronous callback processing of Alipay and Tenpay in 3.OpenCart, it is better for unset ($_ GET ['route']) to verify the payment callback again, otherwise the callback verification will not succeed because this extra parameter participates in the calibration check.

4. Wechat sends data streams when calling back notify, so GET and POST cannot get the data notified asynchronously after payment. You can modify it by using the official SDK:

$GLOBALS ["HTTP_RAW_POST_DATA"] = file_get_contents ("php://input", "r"); $notify = new PayNotifyCallBack (); $notify- > Handle (false)

Alipay of 5.PC browser will pop up Alipay client to pay when accessing with ios device, so you can't receive asynchronous and synchronous notification, so you need to judge whether the access device is mobile or client. If it is mobile, you have to use Alipay's wap method to pay.
