3. Feedback method

When the payment is successful, Yibao will visit here
Access in two ways:
1. Guide the user's browser redirection (if the user closes the browser, he cannot access here)
2. Yibao's server will Access this method using point-to-point communication. (Success must be returned, otherwise the Yibao server will keep calling this method)
