I want to make a payment on the web page as follows:

Options = {...,

    notify_url: URL::to('payment'),    }    

Both the QR code and scan code are successfully generated. No problem.

But: cannot be executed in policy_url?

URL: to ('payment') is defined as follows:
Route: get ('payment', '. Controller @ payment'); (do not know whether to use get or post ??)
Method Content:

$ Request = new policyrequest (); ...... the content is not changed. Use the code in example directly.

This address can be opened directly. The content is as follows (not sure whether it is correct ):

This XML file does not appear to have any style information associated with it. The document tree is shown below.

Please give me some advice. I 've been depressed for several days. Thank you !!
