Then the previous version was detached from the previous version of Access-token and ticket

on the code;

This modification will obtain tokens and ticket separated, respectively encapsulated in the function;

The last parameter of each function is a callback parameter;

The parameters of the callback function are the results that need to be processed in this step;

How to deal with the result, according to the function passed in;
