Pure white, such as the topic, I was self-taught access API this, there is now A API requires authorization, I'll visit the API access token is returned including refresh token and access token, reoccupy token to access another API, I understand the concept of the two, just after the accesstoken expired use refresh token for the latest accesstoken, but specific steps or A face of meng, assuming that access token API is A, to access the actual API is B, then I'll accesstoken is expired after refreshtoken revisit B will get here? Or visit A, but how should visit A the refreshtoken to go in!
Or is my both guess wrong, what should I get back! Trouble to write specifically, thank you
