Overview#

This documentation explains how to develop this project.

Prerequisites#

  • Python 3.7+
  • APISIX 2.7.0+

Debug#

  • Run make setup installation dependencies
  • Run make install installation runner to system
  • Run make dev to start it

Plugin#

Plugin directory#

/path/to/apisix-python-plugin-runner/apisix/plugin

the .py files in this directory autoload

Plugin example#

/path/to/apisix-python-plugin-runner/apisix/plugin/stop.py/path/to/apisix-python-plugin-runner/apisix/plugin/rewrite.py

  • Plugins must inherit the PluginBase class and implement all functions.
    • name function: used to set the registered plugin name.
    • config function: used to parse plugin configuration.
    • filter function: used to filter requests.
      • conf parameter: plugin configuration after parsing.
      • request parameter: Request object, which can be used to get and set request information.
      • response parameter: Response object, which can be used to set response information.

Test#

Run make test.
