After receiving a completed package, you can go to the nature of the protocol (because the association of the association is not encrypted, so you don't have to do this again here, huh, huh J, you can just relax your mind) . If you receive a completed game data with CommView or other tools, you will find such a data process: 1, 0x0000 00 02 00 80 C8 00 00 00 00 00 00 04 00 02 00 ... €? ... ....... 2, 0x0050 17 20 00 00 04 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 0000 000000 0000-00-00 00 00-01 00 E0 00 01 00 00 00. ........? .... 4, 0x0000 03 20 00 00 04 00 00 00-01 00 00 00. ........ .. Then there is a pile of data as in the following 5, 0x0000 0D 20 00 00 38 00 00 00-01 00 00 00 01 00 00 00. ..8 ........... Finally, there is a Such a command 6, 0x0100 15 20 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 02 65 67 65. ......... Ege If we still remember the order of playing cards when playing upgrades: login, send Brand, called card, start, play card, end, follow the above instructions, huh, now you will understand the role of these instructions, because these orders will appear every time, so as long as the reception has played a card The data of the whole process can be analyzed. (Different colors identified above, the previous part is the command word, the latter part is the length of the package, this point is in the previous article)
.......to be continued
