Installation

2. Start setup.py file from this repository:

   python setup.py install

Usage

You can import the module in the following way:

import axessy.axessy

In this package there is the "AxessPackage" class defined with the following methods:

• parsePacket(params): "params" includes the GET parameters sent via an "/online" or "/batch" command from the device, and stores the data inside the class variables;
• message(msg, beep=100, show=2): builds a string that you can put inside an HttpResponse to send back to the device;
• sendKeepAlive(url, username, password): asks the device to send a keepalive message.

Also the "AxessPackage().ack" and "AxessPackage().keepalive" variables are defined for string responses to "/batch" and "/keepalive" commands.

A dictionary with all possible errors saved into a transaction, "AxessPackage().error_dict", is defined and automatically used by "parsePacket" method.

Finally there are two new Error classes used by the "checkPacket()" method (this method is used by "parsePacket" automatically):

• MacAddressError
• CardError
