Using Nginx+uwsgi+redis to realize the game GM chat function

Original demand

A customer service GM can add all the players in the game to be friends and chat. The specific functions are as follows:
* GM up and down
* Add game players as friends
* Delete Game players as friends
* GM sends chat messages
* Player Push Chat message
Additional qualification: A GM account can add multiple gamers as a friend, while a gamer can only be added by a GM account

Demand analysis

Because we are not in the game to cross-serve chat, cross-service friends this feature, and will not be supported in the future, so let GM in the game to create characters, and then add the game suit players to chat The program is not implemented. And GM isn't really a game character, and it doesn't have to be created inside the game.
The whole difficulty is how to get each game suit to access the various data sent by GM, how to push the player's data to GM.

Specific implementation

In order to implement the GM data on each server, we have adopted a simple solution: Put the GM data on our web server, the various game uniforms from the Web server to pick up the data.
This scheme is simple, the Web server and the game suit do not have long connection, directly with the HTTP GET and post method can take the data. The entire architecture is as follows:

   GM1  - - - - - - -  operation and Maintenance Chat Service  - - - - - - - -  Game Web Server  - - - - - -  Game server 1  - - - - - - - -  Game Client 1   |   |   |   |   |   |   GM2   Game server 2   Game Client 2   

Here customer service GM1 and GM2 both use the Web interface to chat with the game client.
Operation and maintenance Chat Service exists because:
* The creation of GM needs to be approved by operation and maintenance side.
* The game Web server can be whitelisted, only the IP of the OPS Chat Service can access the game's Web server
Only the game client and the game server is the TCP long connection, the other is the use of HTTP short connection to achieve.
The Web server uses Nginx, not nodejs. The Nginx scheme is quite mature and easy to deploy.
Since I am much more familiar with Python than Lua, I use UWSGI as an agent instead of writing it directly with Lua.
And the database is used by the Redis,redis set up a timed disk. Data format settings can refer to my premise of the article, basically is
gm:%d:nameIn this format, key indicates what GMX's name is, and Val represents the name.

Implementation code

The configuration of Nginx and Uwsgi has been omitted. For privacy reasons, the relevant IP has been omitted, the code also has enough comments, no longer repeat:
