-- Extending the Base Plugin handler is optional, as there is no real
-- concept of interface in Lua, but the Base Plugin handler's methods
-- can be called from your child implementation and will print logs
-- in your `error.log` file (where all logs are printed).
local BasePlugin = require "kong.plugins.base_plugin"
local CustomHandler = BasePlugin:extend()

-- Your plugin handler's constructor. If you are extending the
-- Base Plugin handler, it's only role is to instanciate itself
-- with a name. The name is your plugin name as it will be printed in the logs.
function CustomHandler:new()
  CustomHandler.super.new(self, "my-custom-plugin")
end

function CustomHandler:init_worker(config)
  -- Eventually, execute the parent implementation
  -- (will log that your plugin is entering this context)
  CustomHandler.super.init_worker(self)

  -- Implement any custom logic here
end

function CustomHandler:certificate(config)
  -- Eventually, execute the parent implementation
  -- (will log that your plugin is entering this context)
  CustomHandler.super.certificate(self)

  -- Implement any custom logic here
end

function CustomHandler:access(config)
  -- Eventually, execute the parent implementation
  -- (will log that your plugin is entering this context)
  CustomHandler.super.access(self)

  -- Implement any custom logic here
end

function CustomHandler:header_filter(config)
  -- Eventually, execute the parent implementation
  -- (will log that your plugin is entering this context)
  CustomHandler.super.header_filter(self)

  -- Implement any custom logic here
end

function CustomHandler:body_filter(config)
  -- Eventually, execute the parent implementation
