Go to the homepage after successful payment. Then the callback does not respond. Is it my jump problem?

... Success will be achieved after 10 thousand pitfalls. An error occurred while calling back .. I still don't know where it is. Please refer to the clear path.

The callback function in the second figure cannot be confirmed to be successful. you have to check the asynchronous notification url set in the first figure. after the user makes the payment, the asynchronous notification url you set will be accessed over there, return some parameters to this page, which is ineffective; otherwise, your url is set incorrectly; or the callback page has a bug. isn't there any debugging tool, it's okay to listen to the page.
