This is a simple implementation of REST using Websockets.
Websockets are a way of creating a persistent connections between the client and server. These sockets allow bi-directional data transfer without the need of long-polling or refreshing. Since these are also based on HTTP so only one HTTP request is sent to the server for establishing the connection.
Django-channels are used in this project as a dependency.
There are 3 main actions which a user can do via minimal UI.
-
Start a new request on the server. Takes 3 arguments which are connid, time and route
connid -> Specifies the connection ID for a particular request.
time -> Timeout for the request.
route -> Specifies which Consumer should be invoked for handling this request. In this case it is request
-
Kill a running request on the server. Takes 2 arguments which are connid and route
connid -> Specifies the connection ID for a particular request.
route -> Specifies which Consumer should be invoked for handling this request. In this case it is kill
-
Get the status of all the running requests on the server. Takes only 1 argument which is route
route -> Specifies which Consumer should be invoked for handling this request. In this case it is status
All the communication between the client and server happens over JSON which is also a standard way of communication over the Channels.
