Cocos2dx Network (2) Token Generation

Token, certificate. For HTTP connections, the main function is to distinguish the (when) The request logs on. Therefore, it must meet the following requirements:

1. Uniqueness. Different users have a unique token for each login.
2. Valid time. The token expires.
3. Start time. No, this cannot be used to check whether it is invalid.

Based on the above three points, a simple Token Generation and verification is compiled:

1 import time 2 Import base64 3 4 class token: 5 # playerid can be replaced with your own string to ensure that each user has a different 6 def gettoken (self, playid, delaytime ): 7 curtime = int (time. time () 8 # You can modify 9 mystr = STR (playid) + '$' + STR (curtime) + '$' + STR (delaytime) 10 token = base64.encodestring (mystr ). strip () 11 return token12 13 # Check whether the time is valid. 14 def istokenvalible (self, token): 15 base64text = base64.decodestring (token) 16 strlist = base64text. split ('$') 17 curtime = int (time. time () 18 starttime = int (strlist [1]) 19 if curtime-starttime> int (strlist [2]): 20 return false21 else: 22 return true
