This module provides python binding for the Mongoose web server.
|
|
|
|
There are two classes defined:
|
|
|
|
Connection: - wraps all functions that accept struct mg_connection pointer
|
|
as first argument.
|
|
|
|
Mongoose: wraps all functions that accept struct mg_context pointer as
|
|
first argument.
|
|
|
|
Creating Mongoose object automatically starts server, deleting object
|
|
automatically stops it. There is no need to call mg_start() or mg_stop().
