Access data on remote server by Repository pattern and unit of work pattern

I am building a game that require access to the game server.

How could I use repository pattern and unit of work patterns to access the data on the server via HTTP request?

Below is the interface that I use to send request to the HTTP server.

public interface IRequest{
    void Request(string path, WWWForm form, bool isRequireSession = true, Action<JsonData> onSuccess = null, Action<JsonData> onFail = null, Action<JsonData> onError = null);
}
