Simple use of socket in Cocos2d-x

Cocos2d-x socket simple socket

Summary of How to Use SOCKET today, in Baidu .. The link found above (there is a link to Baidu, which is not fully written. You can check the link ,)... If any big God has a new demo, please share it !!!

In the Cocos2d-x about the network request: Get post put Delete (the latter two I rarely used in development), there is socket (for timely communication, network game teammates call ).

Create a project under vs (remember that it is not a Cocos project !!!) C ++ file. As a server

Note the header file introduced at the beginning, notoneless !!!

The following is the client:
